INTRODUCTION
History of the Pavlovsk Bus Plant
The history of PAZ began to be laid at the beginning of the 20th century. The construction of the Pavlovsk Bus Plant began in early August 1930. At that time it was known as the Automotive Tool Factory. But by the beginning of 1932, the construction was completed and on December 5, 1932, the plant was recognized as operational. This kind of tool was the main production focus of the Pavlovsk Bus Plant until 1952, with a break in 1941-1945. (during the war years, the company was directed to the production of ammunition).
Formation of the PAZ automobile plant
By a decree of the Government of the USSR in 1952, the Automotive Tool Plant became the Pavlovsk Bus Plant due to a shortage public transport(negative consequences of the war). A plan for the reconstruction of the plant and a program for the production of 10,000 buses were also approved. The first batch is being produced, which consists of five PAZ-651 bonneted buses.
In 1989, the last time the PAZ-672 model was released from the factory. At the end of the same year, without stopping the production process, the serial production of the current basic model of the PAZ-3205 bus was launched. This bus model has become the face of the PAZ automobile plant. Also, about thirty modifications of this bus were developed by the plant's engineers, which were designed for operation in various climatic conditions. Only about 10 modifications were mass-produced. This model of the PAZ bus has proven itself perfectly on the roads of our country, which was noted directly by passengers.
In 2000, production was directed to the manufacture of buses of large (PAZ-5272) and middle class (PAZ-4230 "Aurora"). In the same year, the PAZ automobile plant was merged with the RusPromAvto management company. Pavlovsk Bus Plant has repeatedly confirmed its reputation as the largest and leading Russian manufacturer buses.
In 2000, the restructuring and optimization of production processes was also launched, and already in 2003 it covered all divisions of the Pavlovsk Bus Plant, which led to excellent results. This can be seen in the union of workshops in one building:
Welding and painting;
press;
Metal procurement.
Close attention was paid to the optimization of the production of the PAZ plant, and therefore work was started in the assembly shop according to the methods of the Toyota company. The result was on the face.

2.TRANSMISSION
The torque generated by crankshaft engine, is transmitted to the driving wheels of the car through the units and transmission mechanisms.
In PAZ - 3205, the rear wheels are the driving wheels and the power transmission consists of a clutch, gearbox, cardan drive, final drive, differential and axle shafts.
2.1 Clutch
The clutch serves to briefly disconnect the engine from the transmission (when shifting gears in the gearbox) and smoothly connect the engine and transmission (when starting off).
The principle of operation of the clutch is that the torque is transmitted due to the friction that occurs between the drive and driven discs, pressed against each other by springs.
The clutch is mounted on the flywheel, which is one of its drive discs.
The PAZ-3205 clutch is designed and operates as follows (see Fig. 1). Twelve springs (12) press the driven disk (3) through the pressure plate (4) against the ground surface of the flywheel. The driven disk is mounted on the splines of the drive shaft (9) of the gearbox. Thus, when the clutch is engaged, the torque from the flywheel is transmitted by friction to the driven disk and then through the drive shaft of the gearbox to subsequent transmission mechanisms.
The clutch drive is mechanical. To disengage the clutch, press the pedal (16) so that the rod (14) with the adjusting nut (13) turns the lever (18) of the fork, which moves the clutch (8) with the bearing (20) along the sleeve. The clutch will rotate the inner ends of the levers (5) around its axes, and their outer ends will retract the pressure plate, compressing the springs located between the stamped steel casing (11) of the clutch and the disc (4). The driven disk is released, and the torque will not be transmitted to subsequent mechanisms. If you release the pedal, it will move under the action of the springs (15 and 19) and the clutch will reengage.
A thrust ball bearing installed in the clutch reduces friction between it and the ends of the levers at the moment the clutch is released. The fork (18) is fixed to the clutch housing (2) by means of a ball joint.
When the clutch is engaged, its parts heat up due to friction between the drive and driven discs. Heat-insulating washers located between the pressure plate and the springs reduce the transfer of heat to the springs, which lose their elastic properties when heated.
Clutch disc. Six spring corrugated plates and two friction linings are riveted to the steel driven disk. Linings are made of pressed asbestos fiber impregnated with Bakelite or synthetic resins and have a high coefficient of friction.

PAZ 3205, 2006
Hello. I have been working on it for 4 years, running about a hundred thousand kilometers along the Volgograd roads - this is not a joke to you. PAZ 3205 is a very good device. Its biggest drawback, in my opinion, is the ZMZ-53 engine - it is rather weak for a bus. And, of course, the clutch. This bus was originally created for rural areas, trips from town to village, for regional and suburban routes with low passenger traffic. The designers in a nightmare did not assume that the PAZ 3205 would be used as one of the main buses in major cities. After all, what we proudly call "route taxi", in fact, is an ordinary regular regular bus service. No one imagined that the PAZ 3205 would systematically (several times a day) be packed up to the nominal (5 people per square meter), or even full (8 people per square meter) capacity. The bus is fast enough, has sufficient (with human occupancy) comfort. Although very tough. Withstands poor maintenance and the most brutal treatment. Yes, the machine has been outdated since its inception. Well, the Pavlovsk Plant has a new (2006) and much more advanced model 3204.
Advantages : Fairly durable. Good permeability.
disadvantages : obsolete. Hard. Gluttonous and weak gasoline engine.

PAZ 3205, 2009
The bus is quite simple with an outdated design. Hardy, but in terms of reliability, not very. There are disadvantages - pneumohydraulic brake drive. With all the ensuing consequences. In the literal sense, the cuffs on the working brake cylinders last for a very short time, that is, if you replace the pads and cylinders at the same time, then it is not a fact that the cylinders will live until the next replacement of the pads. And to replace them or brake cylinder, it is necessary to unscrew the wheel nuts with fittings. Exactly, there is one more minus - futorki. Far from always, this dirty trick is unscrewed immediately, even if it is abundantly lubricated during assembly, and sometimes you have to use a grinder or throw off the hub. Well, if you do all this in the garage, and not on the road, with nervous passengers in the cabin. But what I liked about PAZ 3205 was power steering. By 10 years of operation, ABS begins to “fail”, the brakes sometimes work, sometimes they don’t. The solution to the problem is disconnecting the wiring harness under the driver's seat. And try to smear the fittings with copper grease, of course, you can’t unscrew them by hand, but they go much easier.
Advantages : simple. Inexpensive. Perfect for rural areas - good cross-country ability. GUR.
disadvantages : hard. Not very reliable.

PAZ 3205, 2017
The bus of 2017 is no different from the old PAZ 3205 models. The interior, as it was bad, remained. Gasoline carburetor engine, does not pull at all, does not start without jerking without degassing, the clutch is disgusting, the noise is terrible, the gearbox with double release and regassing is rarely possible to change gear without a crunch, you need to squeeze the clutch with both feet, when driving in first gear such a howl is worth , which I think is about to break the checkpoint. The fuel consumption of the PAZ 3205 space is 37.95 in the city, how did they manage to reach the euro at all, not to mention euro 2, 3 or 4, but how is this disgrace still being produced?
Advantages : hardy.
disadvantages : obsolete in everything.

PAZ 3205, 2015
The PAZ 3205 bus is a museum exhibit. In general, in Russia they do not like and do not know how to make equipment for people. Inconvenience - both for the driver and passengers. But if the passengers are temporarily staying on the bus for a trip, then the driver is constantly on the day-to-day. With a gasoline engine, the bus does not have enough power at modern speeds. Clutch, gearbox - leave much to be desired. In addition to the fragility of the clutch, there is also such a property as freezing when low temperatures, the brake pneumohydraulic system also freezes, as a result of which not only operation, but also safety worsens (and the lower the ambient temperature, the worse the operation of the clutch and brakes). Cramped driver's seat. Installing rearview mirrors creates dead zones when reviewing. Between the driver's panel and the windshield, waste bins in the form of recesses are created by the factory. Poor blowing of windshields at low temperatures, repeaters of direction indicators are installed outside in an ill-conceived place, which contributes to throwing dirt from under front wheel. There are also questions about the tightness of the doors and the interior heating of the PAZ 3205. As for heating, we can say the following: in winter, the PAZ 3205 bus is a refrigerator, and in summer it is an oven. With diesel engine there are also problems - since the engine itself is very noisy, and working with such noise for a long time is simply unbearable. The brake system was converted to pneumatic - this is a plus, but the conversion of bumpers from metal to plastic is the “know-how of the factory” (since plastic bumpers even crack at low temperatures and, in my opinion, it would be better if the bumpers were completely removed or they came up with something something more original). Still - outside the joints of the body are sealed with tape and sheathed with aluminum strips, under which moisture gets in and corrosion of the metal soon appears. In general, you still need to work and work on creating a normal bus, because in other countries they somehow know how to make pretty good equipment.
Advantages : No.
disadvantages : in a review.

Introduction
PAZ 3205 is one of the most popular domestic buses. 3205 is the basic model of the plant, on which a wide number of different modifications are built. The bus has been developed for almost 15 years by creating about 10 prototypes. Serial production of the model started on December 1, 1989. PAZ 3205 replaced the mass PAZ 672 on the conveyor, which was outdated at that time. On June 4, 2001, the plant celebrated the production of the 100,000th PAZ 3205 bus. In 2008, the equipment at the plant was modernized, which made it possible to produce equipment more productively. Despite the outdated design, PAZ 3205 can often be seen as fixed-route taxi, commuter or district bus. Also, PAZ 3205 is widely used as Vehicle ritual services, educational institutions.
On the Russian market PAZ 3205 has proven itself exclusively with positive side. The bus has a strong structure, endurance, maintainability and ease of maintenance. PAZ 3205 can be equipped with both gasoline and diesel engines.

Conclusion
The PAZ 3205 bus is quite simple to maintenance. It is beneficial, as PAZ 3205 quickly pays for itself in commercial use, and also has an excellent price-quality ratio. Plus, PAZ 3205 has optimal technical characteristics. Today, this bus is one of the most popular in its class, since, having small dimensions, it is quite nimble and quirky.
The PAZ-3205 bus is a basic model of a small class produced at the Pavlovsk Bus Plant. This high-floor vehicle with compact dimensions is perfect for transporting small groups of passengers over short distances. The bus, like most domestic models, does not have much comfort, but is perfectly adapted to Russian roads and fuel, has good cross-country ability, is simple in design. High ground clearance allows the use of equipment in off-road conditions.
History of creation
The prototype of the PAZ-3205 was the PAZ-665, created in 1966. Initially, 2 versions were developed - for urban and tourist transportation. Tourist buses more comfortable interior fittings. However, the initial tourist modification of the PAZ was not mass-produced. The improvement of the device of the model lasted almost 15 years, during which time 10 different versions were created.
The PAZ-3205 model, in the form that we know now, appeared after the choice of the Gorky Automobile Plant as the main supplier of aggregates and assemblies. The first buses of this modification were produced in 1981. After carrying out measures to improve the design in 1986, the production of small volumes of the PAZ-3205 model began. Serial production of equipment began in 1989. It was equipped with two types of engines - gasoline and diesel. Doors - front automatic, rear - emergency, bridge - from the GAZ car, brakes - hydropneumatic.
PAZ-3205 modifications
In 2009, after the initial model was discontinued, the development of its improved modifications continued. The comprehensive modernization of the PAZ-3205 consisted in the replacement of Ukrainian and Belarusian products with German components and assemblies, in the appearance of plastic trim gray color and anti-corrosion tape at the joints of the body, the development of new layouts for passenger seats and the cargo compartment. New equipment heating system provided the possibility of using cars even in severe frosts. Since 2002, all equipment has been equipped with an ABS system.
PAZ-32053. Single-door modification, has air brakes and a carburetor engine.
PAZ-32054. Double door bus. The doors open from the driver's seat. The engine is petrol.

Advantages of PAZ-3205 and its modifications
The lack of comfort of these buses is compensated by a number of advantages, thanks to which the brainchild of the Pavlovsk Bus Plant has been widely used on the roads of Russia for several decades:
- A wide range of models that allows you to choose a modification that best suits the intended purpose, load, routes, climate.
- Possibility to order an individual complete set of the car intended for rendering emergency assistance, laboratory services, servicing various groups of the population.
- Simplicity and convenience of a design, a possibility of use in difficult road conditions.
- Ability to carry out repairs by the driver. While modern imported buses, equipped with electronic blocks and other technically advanced devices, can only be repaired in the conditions of specialized services.
- High reliability, thanks to which this machine is effectively operated on urban, rural, rural roads, for servicing industrial and agricultural enterprises.

My last video about the PAZ bus.

The prototype of PAZ buses known to the entire population of the post-Soviet space was the PAZ-665 model, developed by the designers of the Pavlovsk Bus Plant back in 1966.
The history of the appearance of buses of the PAZ-3205 series
The bus was developed in two versions - a city bus with two double-leaf automatically opening doors, and a tourist version of the same car, which differed from the basic version in the presence of comfortable seats in the cabin and one manually opened door. The body design and interior layout of the experimental model vaguely resembled the PAZ-3205, the release of which was launched much later.
In 1967, the tourist version of the bus, which received the PAZ-665T index, was demonstrated in Paris, at the international motor show, where it was awarded the Grand Silver Medal of the French High Commissariat for Tourism and the motor show medal.
PAZ 665T Experienced (EC-96)
At the same time, the plant was preparing for the production of another bus model - PAZ-672, developed several years ago. The Ministry of Automobile Industry of the USSR decided to produce this particular model, as a result of which the international prize-winner PAZ-665 did not go into production, remaining an experimental model.
Later, several more experimental models were created at the plant with a layout identical to PAZ-3205. So, in the 70s, several modifications based on the PAZ-3202 were developed. Their launch into mass production was scheduled for 1979, but production problems that arose at ZiL, which is the main supplier of components for the Pavlovsk bus, prevented the existing plans from being realized.
Experimental PAZ-3202. The series was not released.
To get out of this situation, it was decided to change the base supplier, and switch to components and assemblies supplied by the Gorky Automobile Plant. As a result, it has developed new model, which received the PAZ-3205 index, the first prototypes of which appeared in 1981. In the design of the new model, many flaws were discovered, the elimination of which took several more years. Only in 1986, small-scale production of the PAZ-3205 was launched, and, finally, in 1989 the bus went into series, replacing the obsolete 672 model.
pre-production PAZ-3205
The new bus was significantly different from its predecessor. PAZ-3205 received a spacious, comfortable, bright interior with a large glass area. However, the model in its own way technical specifications somewhat inferior to the previously developed version 3203, since the parts and assemblies supplied by GAZ were inferior to the ZiL counterparts.
The bus was equipped with a ZMZ-5112 engine with a capacity of 125 horsepower, and was not much different from the engine that was equipped with the 672nd model. The gearbox, brake system and axles were supplied from GAZ, the steering mechanism was produced at the Minsk Automobile Plant.
From the beginning of serial production until 1991, the bus was delivered to all the republics of the USSR, the pace of production was constantly increasing. However, the collapse of the USSR and the long crisis that followed led to a sharp decline in production at PAZ. Nevertheless, even in crisis conditions, the factory workers managed to put on the conveyor the urban modification PAZ-32051, and in 1995 the modernized PAZ-3205-07 with a diesel unit MMZ D 245.7 produced by Belarusian machine builders.
PAZ-3205 special order 10 pcs. for the 27th Congress of the Central Committee of the CPSU
By the second half of the 1990s, the plant again saw an increase in production, which, paradoxically, was facilitated by the ongoing crisis in the country. The fact is that many automobile enterprises engaged in passenger transportation, due to the high cost, were not able to purchase large, spacious buses, and replaced them with much more accessible grooves. True, in the same period, cases of serious accidents involving these buses became more frequent, which was associated with numerous violations of operating rules and the low reliability of the hydraulic brake system.
PAZ 3205 1989, LUX equipment
By the beginning of the 2000s, the Pavlovsk Automobile Plant, in general, had overcome all the difficulties of the transition period and began to produce better and more reliable modifications of buses. AT model range a single-door PAZ-32053 and a two-door PAZ-32054 appeared, equipped with axles manufactured by the Ryazan auto-aggregate plant and new pneumatic brakes. By 2002, these models were finalized and equipped with an anti-lock system. ABS brakes. Gradually, the new Pavlovsk buses replaced the outdated PAZ-3205 and PAZ-32051 models.
Bus PAZ-32051
In the same 2002, some changes appeared in appearance buses. So, the rear emergency door, previously located at floor level, was brought to the level ground clearance, and the glazing area of the emergency door was slightly reduced. Also in the interior of the buses appeared handrails covered with polyurethane coating.
A few years later, in 2007, Pavlovsk buses underwent a very serious modernization. The most problematic units, which caused complaints from the operators, were replaced with imported counterparts. So, the Ukrainian-made compressor was replaced by a similar unit manufactured by a German company. The same fate was awarded to the ABS "Ekran" system of Belarusian production.
In addition to replacing the units, work has been done to improve the quality of the assembly. So, the joints of the body elements began to be glued with a tape that protects the metal from corrosion, the front of the buses received a new plastic lining.
Not without changes in the cabin of the bus. The floor was covered with impregnated special composition plywood, chipboard sheathing was replaced with plastic, doors began to be made of galvanized steel.
The driver's workplace is now separated from the passenger compartment by an incomplete partition, the headlight switch has moved from the floor to the steering column, mirrors with an electric heating system have appeared. Customers were able to order different color options for the interior and exterior of cars in accordance with different finishing schemes.
Nevertheless, despite regular improvements and upgrades, it should be recognized that the PAZ-3205 bus has long and hopelessly become outdated. Ancient gearbox from GAZ-53, gluttonous, not corresponding to modern environmental requirements ZMZ and MMZ power units, outdated design - all this persistently and urgently required replacement.
Test drive PAZ-3205
A few years ago, we were “lucky” to get to know two PAZs closely - gasoline and diesel. Both cars recently left the assembly line, and their mileage was practically zero. But they gave us so many problems that our head was spinning.
What is worth just the side glass falling out of the window opening when performing maneuvers at the training ground? On the second bus, the gearbox was malfunctioning, we did not manage to turn on one of the gears. The outside rear view mirrors were constantly falling off from the vibration. In a word, then, six years ago, the “grooves” left far from the best impression, and it would be interesting to see what has changed over the past years and have the “popular” autobuoys become better?
Three models were chosen for the test drive: PAZ-32053, equipped with a ZMZ-5234.10 gasoline power unit with a mileage of 27,000 km; diesel PAZ-32053-07 with MMZ engine-245.7, having a mileage of 28000 km and PAZ-4234 with an extended chassis base and an increased capacity interior, equipped with a more powerful diesel engine MMZ-245.9E2 with a mileage of 15400 km.
First of all, it caught the eye of a much more high quality bodies. In the buses we tested six years ago, the rust on the rough, sloppy welds was visible even in the cabin. Now everything has changed - the seams are carefully welded, covered with a layer of primer and paint.
Unlike before, the ventilation hatches with rubber seals on the roof of the buses are now tightly closed and do not let in moisture even in heavy rain. Do not fall out now, in contrast to previous times, and side windows. In general, after the first meeting, the impression was that the quality of assembly, anti-corrosion treatment and body painting has increased by several orders of magnitude.
Among other things, it is now used in the assembly of buses new technology anti-corrosion treatment, including the filling of empty cavities, most subject to corrosion, a special compound "Dinitrol", guaranteed to protect the treated surface for six years.
Models 32053 and 32053-07 with gasoline and diesel engines are built on a standard chassis with a body equipped with a double-leaf door that opens with a pneumatic actuator.
An emergency exit door is installed in the rear of the cabin.
In both models, the interior layout is almost the same, although there are certain differences in the number passenger seats and total passenger capacity. There are 25 passenger seats in the PAZ-32053 cabin, and 22 such seats in the PAZ-32053-07 cabin.
Models PAZ-32053 and 32053-07 are small class buses, but PAZ-4234 is already a middle class model equipped with two passenger doors. Of course, in the extended version of the bus, the body configuration and the layout of the cabin have changed, in which a second storage area has appeared. In the extended version, the passenger capacity of the bus has been increased to 50 people, 30 of which can be seated.
The bodies of all tested models are made in a wagon layout, without a partition separating the driver's compartment. It is worth noting that not all drivers are satisfied with the lack of a partition, but it just so happened that on the PAZs workplace The driver has never been fenced.
The driver's seats installed on the buses are quite high quality. The presence of adjustments and suspension create comfortable conditions for the driver when making long-distance flights. But you can’t call the passenger seats comfortable, although you can’t classify them as frankly bad either. But the interval between the seats in the cabin is quite decent, the knees do not rest against the back of the front seat.
A few words about cabin ergonomics. PAZ is equipped with a steering wheel that is optimal in diameter and thickness of the rim. But the lack of steering column adjustment somewhat reduces the level of driver comfort. Surprisingly, many upgrades to the car did not affect the pedal unit and headlight footswitch. As on the first PAZ models, the switch is still located next to the pedals.
In subsequent modifications, it would be optimal to provide for the possibility of duplicating the headlight switch by installing it on the steering column, and, at the same time, retaining the foot button, which has become convenient and native for the drivers of the "people's" bus.
Most drivers and technicians like the layout of the bus with an internal engine. It just so happened that domestic vehicles are not highly reliable, and malfunctions of various components and assemblies quite often catch the driver on the road. So let's imagine that a similar breakdown occurred, and there was snow, slush, and frost outside the car. As a rule, in such a situation, the driver has to dress warmly, pull on mittens and fiddle in the cold, sometimes for quite a long time, with a faulty mechanism. But the PAZ drivers are lucky - they do not need to leave the cozy, warm cabin. It is enough to open the hood of the engine compartment, located right there, and calmly engage in repairs.
PAZ-32053 with petrol engine ZMZ-5234.10
We will not draw analogies between power units test specimen with a machine that gave us a lot of trouble six years ago. Then we were dealing with an unrolled unit that had just rolled off the assembly line. Now we came across a copy, the "childhood diseases" of which have long been eliminated by drivers and technicians operating the car.
On the idling engine noise is almost inaudible, but a characteristic sound similar to the scream of a black grouse comes from the pneumatic compressor. At higher speeds, the engine makes itself felt, turning off the pneumatic compressor, reminiscent of the good old GAZ-53 truck.
The engine power of 130 horses provides the bus with a rather frisky start. In the first four gears, the gearbox worked flawlessly, but when turning on the fifth and reverse, there were some difficulties. When you turn on the fifth gear, there was always a slight rattle, and the reverse one turned on hard due to the limited travel of the lever.
PAZ also showed good dynamics on the road, the accelerator pedal was pleased with its smoothness and responsiveness.
Until 2003, buses were equipped with a double-circuit braking system, with hydraulic and pneumatic brakes. After modernization, only pneumatic brakes were installed on the grooves, which made it possible to use anti-lock braking ABS system produced by the German company Knorr-Bremse. But the brake pedal, as before, is located unsuccessfully, as it is at different levels with the accelerator pedal.
Not very convenient and too high location of the hydraulic clutch pedal. In city driving conditions, the driver is forced to constantly keep his foot on the clutch, which creates a feeling of discomfort with such a pedal arrangement. Drivers working on suburban routes do not have such problems, because on a free track it is not necessary to constantly keep your foot on the clutch.
As for maneuverability, this characteristic was and is one of the main advantages of Pavlovsk buses. It is enough to note that with a turning radius of 8.5 meters, the PAZ makes a U-turn in two steps on a road 6 meters wide. It should also be noted the impeccable operation of the power steering, which operates easily and silently.
During the test drive did not cause any complaints and chassis. The buses are equipped with bridges manufactured by the Ryazan and Kanash auto-aggregate plants. The test specimen was equipped with a Ryazan bridge, and, perhaps, therefore, did not make a typical howling sound characteristic of GAZ trucks.
PAZ-32053-07 with Minsk diesel engine
All the advantages and disadvantages that we noted when talking about a car with a gasoline engine are also characteristic of a bus with a diesel power unit.
Being next to the bus running engine, it is difficult not to pay attention to the characteristic noise of the Minsk diesel engine MMZ D-245.7. If you do not see that there is a bus nearby, you might think that the Belarus tractor is working nearby. The designers of the Pavlovsk automobile plant worked hard to reduce the engine noise level, bringing it up to certification standards, but they failed to completely get rid of the “tractor motives”.
In the cabin, the engine noise is not so noticeable, especially compared to a similar car six years ago, in which it was problematic to hear the interlocutor.
Dynamic characteristics gasoline and diesel engines are almost identical, but in terms of fuel consumption, diesel is much more economical, which increases the profitability of its operation.
It should be noted that PAZ-32053-07 and PAZ-4234, corresponding to the middle class and equipped with a more powerful diesel unit, have almost similar fuel consumption indicators.
An extended version of the PAZ-4234 bus is equipped with a reinforced Ryazan-made axle and a five-speed mechanical box familiar to us from ZIL trucks.
The expected somewhat sluggish dynamics of the elongated PAZik is compensated by a larger capacity, the bus can carry up to 50 passengers, which is 10-12 people more than small-class brothers can take on board. The successful layout of the passenger compartment made it possible to organize two fairly spacious storage areas.
Naturally, on this model it is impossible to make a U-turn in two stages on a road 6 meters wide due to its dimensions. With a length of 8.2 m and a turning radius of 8.7 m, you can’t maneuver in urban conditions, but the bus is ideal for suburban and rural roads.
Concluding the test drive, we can summarize that the Pavlovsk automakers have managed to take a step forward in recent years.
New models of the PAZ-4320 Avrora with a rear engine are already leaving the assembly line of the plant, often on the streets of Moscow you can also find low-floor city buses PAZ-3327, new small-class models with a front-mounted power unit PAZ-3203 are being tested and gradually go into series. and PAZ-3204.
PAZ-4320 "Aurora"
In a word, the plant is trying to keep up with the times, constantly improving both existing models and developing new ones that correspond to the trends of the country's modern bus market.
With all this, it should be noted that the old models are still in demand on the market. Long-familiar and well-established machines attract many with their accessibility, ease of maintenance, and unpretentiousness. Perhaps, foreigners meeting the "people's" bus on our roads may be confused by its outdated design, but it is not produced for Sweden and Germany, but for our people, and the people like it.
What is the result?
The streets of Moscow and other Russian megalopolises, crowded with automotive innovations from the world's leading manufacturers, have acquired the features of European cities in recent years. However, they are not a reflection of the situation on the roads of a vast country. And the situation is such that for a very long time cars and buses will run along the roads of 1/6 of the land, the roots of which go back to the Soviet automobile industry.
In the Soviet years, the lion's share passenger traffic in rural areas and on short suburban routes, it was carried out with the help of Pavlovsky and Kurgan buses. The maneuverable, nimble PAZik has practically not changed since then, but, at the same time, has not lost its relevance and popularity. It is noteworthy that Pavlovsky bus factory was one of the few enterprises in the industry that managed not only to survive, but also to develop during the years of destructive perestroika, and in the dashing 90s, and in the stable zero.
It would not be an exaggeration to call PAZ buses one of the symbols of the country, which has “rallied” several generations of drivers and passengers around itself. If in other countries young people can see the buses that their fathers and grandfathers used only in the movies, our youth can not only see them on the streets, but also ride in them.
However, the high demand for PAZs cannot be associated only with the continuity of generations. The popularity of Pavlovsk buses is largely due to the effective marketing and technical policy pursued by the Russian Buses company, which, in addition to the Pavlovsk Automobile Plant, also includes Likinsky, Kurgan and Golitsinsky bus plants.
To date, in addition to cars with traditional gasoline power units, PAZ has launched the production of buses equipped with various modifications diesel engine MMZ-245. The installation of a diesel engine made it possible to significantly increase the profitability of the operation of machines. Suffice it to say that the fuel consumption of diesel buses is on average 10 liters less than that of gasoline counterparts. In addition to reducing fuel consumption, diesel unit also allowed, to a certain extent, to solve the problem of compliance of buses with modern environmental requirements.
No less successful was the decision to put into mass production the PAZ-4234 middle-class model with increased passenger capacity to 50 people.
Russian Buses is implementing a production modernization program aimed at increasing its efficiency and reducing costs. Evidence of this approach was the rejection of the technology of energy-intensive stamping production in favor of a tubular body frame using polymer outer panels.
For the first time, the new technology was implemented in the serial production of the PAZ-4230 Avrora bus family, which are already being supplied to the market in sufficient quantities.
Of course, the Aurora is quite comfortable, modern bus. But it should be noted that its cost is almost twice the price of the "people's" PAZ-3205, even in its most expensive, diesel version. Thus, it can be argued that the bus, “coming from the people”, is still provided with a long working biography.
