Types of trailers. Traction-coupling devices of road trains. What are couplers needed for?

When it comes to trailers, novice motorists confidently discuss the issues of carrying capacity and maneuverability. But the questions of the towing device are perplexing only because of the definition of the concept. Is it a hitch for a light trailer, or a trailer coupling head, or maybe a drawbar - is it a tow bar ?!

The benefit of acquiring a branded towbar for a car is understandable. What is a towing hitch (drawbar) or a towbar - a hook with a metal ball sticking out below the bumper for throwing a hitch head on it, mounted on the end of a straight or V-shaped trailer drawbar. When there is a need to transport cargo that does not fit in the passenger compartment or trunk, the choice of a trailer is accompanied by questions about the towbar. After all, depending on the fastening, the permissible load on the car frame is calculated. Of course, the weight tables are on the certificates and on the back of the bonnet. But what if the hitch is not installed?

Definitely:

  • Look for a suitable or native brand;
  • In the absence of custom-made or independently.

What is a tow hitch

In practice, two types of TSU have taken root in Russia:



The advantage of this design is the possibility of equipping the trailer braking system, which will work by means of transmitting mechanical vibrations through the ball to the coupling head and ensure leveling of high-speed differences on the road: the car slows down, the trailer presses the lever on the ball by inertia, the brakes are turned on.

Homemade TSUs try to fit into the specific features of the destination. Otherwise, operation may be prohibited. There are many models on the market. All of them are different:

  • By weight classification;
  • By design;
  • fastening method;
  • Electrical fastening features.

Towing with non-standard values ​​can lead to bad consequences. Therefore, the classification of towbars begins with the weight load. Fitting in with your group will ensure long-term viability.

  1. For passenger cars from allowable weight trailer 1.5 t;
  2. For station wagons, minivans with a similar value up to 2.5 tons;
  3. For minibuses, SUVs up to 3.5 tons.

TSU classification:

European design. The difference from domestic ones is the size of the ball, which is marked in inches:

  • 1- 7/8 is equal to 47.6 mm;
  • 2 is equal to 50.8 mm;
  • 2-5/16 - 58.7 mm.

American design. It's a slightly different story. They have the shape of a quadrangular shaft, into which a drawbar tip is inserted with a lock in the form of a hook-shaped handle.

The mounting method involves three types of devices:


Classification of towbars:


The tow hitch is the meeting point of the automotive electrics and the trailer. A socket with 7, 13 or 15 pins is usually mounted on the towbar, and the trailer wiring assumes a similar plug. It happens that the plug and socket turn out to be with different contact options. Choosing a trailer with the right pinout in advance will eliminate the problem. But if this happens, an adapter comes to the rescue.
Manufacturers of towbars, offering their products to the mass consumer, are responsible for the quality of the material and the resistance of the elements in the assembly, which can only be checked in the factory. The requirements of OST 37.001.299 regulate the characteristics. Handicraft towbars live and successfully disguise themselves as original samples. It is good if the craftsman knows the formula for the distribution of weight relative to the car body and the installation of fastening points, but no one guarantees the reliability of the metal.

How to install a hitch

Mounting a towbar on a car

TSU is attached to the frame or body of the car. The bumper is usually removed and its role goes to the main beam of the trailer. In some cases, it is necessary to drill a spar and install embedded plates. But installing a native towbar is a simple matter. If the car manufacturer has provided mounting points, holes and other elements for installing the towbar, and there is also a document (usually a certificate upon purchase) with the characteristics of the original device, then self-assembly is quite legal and logical. The service will offer a certain price. This will pay off if it is planned to drill additional holes or install a non-native towbar, but suitable in terms of characteristics. The service will issue a written opinion on compliance with the standards.

The condition of the ball and the TSU itself requires constant checking for the presence of:

  • Loose, stripped nuts or bolts (grover will prevent loosening, but not stalling);
  • ball lubricants;
  • Cleanliness of the outlet;
  • Weld seams.

The ball experiences critical loads and is subject to wear. It is necessary to measure the diameter every 1-1.5 thousand kilometers.

Tow hitch manufacturers

Finally, a list well-known manufacturers TSU:

  • Bosal - 200 samples for cars and trucks from Belgium;
  • Brink - the leading position from Holland;
  • VFM is a Russian association under the flag of Bosal;
  • Westfalia is a large German company. More than 800 items;
  • Aragon - Spanish leader;
  • HiddenHitch is a North American company;
  • AvtoS - Russian company produces trailers and towbars;
  • BALTEX is a domestic company from St. Petersburg.


Video review of towbars Bosal

When the picture is clear, there is no point in wasting time and inventing what is already in the best possible way. A sound approach to the solution of cargo transportation and competent installation of the towbar will certainly lead to success. And lovers of inventions should at least focus on the owners of golden hands.

Towing device of a tractor car (device and purpose)

An important condition for the effective use of road trains is interlocking, which means the possibility of coupling a car or tractor with various trailer links.

The towing device of tractor vehicles is a towing device, and trailers - a coupling loop and a drawbar.

Rice.

Serves for the operation of the car as part of a road train - with a trailer, and for towing a faulty car.

Two front tow hooks are mounted on the ends of the side members and are each attached with three bolts. The shape of the hook provides a secure fixation of the towing device with a loop of the appropriate size. The rigid tug used by a number of enterprises has different sizes at the ends of the loop, the smaller of which is designed for installation on the front hook. The stop under the loop protects it from spontaneous disengagement from the hook during mutual movements of the tractor and the towed vehicle.

The towing device, attached with tie bolts, is mounted on the rear cross member of the frame, reinforced with braces. The towing device consists of a hook, a rubber shock absorber, a hook latch. The shock absorber on the hook is clamped with a nut between the support washers resting on the housing and housing cover. This design provides a two-way action of the hook, softens axial shocks when the road train is moving. The cap protects the hook coupling nut assembly from contamination. Friction surfaces are lubricated through grease fittings. The pawl locks the hook latch, and the cotter pin keeps the pawl from moving. Thus, spontaneous opening of the tow hook mouth is excluded. The hook nut must be screwed all the way into the rear support washer, while allowing axial movement of the hook up to 0.5 mm. Permissible wear hook link without repair should be no more than 5 mm.

Smaller hinges will result in increased wear, reduced towbar life, and damage to the drawbeam due to hitch loading.

The surface of the coupling loop must be even, smooth, and of regular geometric shape. You can restore the size of the loop by welding metal, but at the same time, its working surface must be protected from the influx of metal and burrs. The loop on the trailer drawbar must be rigidly fixed. When maneuvering a tractor with a trailer, do not allow the road train to fold at a large angle in order to avoid damage to the end part of the frame by the trailer drawbar and breakage of the tow hook.

Characteristics of additional equipment

For the operation of ZIL vehicles in special conditions, a set of additional equipment is provided that is attached to the vehicle or installed on it in addition to the basic (mandatory) completeness.

Complete set of additional equipment for each model truck different.

For ZIL vehicles of models 431410, additional equipment includes: preheater engine; insulating cover of the radiator; extensions of the front and side boards of the body; cloth-blanket on the body; awning with a frame; entrenching tool (saw, ax, shovel); fastening details of a fire extinguisher, entrenching tool; canisters (with fasteners) with a capacity of 10 and 20 liters each.

The fastening of the fire extinguisher and the trenching tool is determined by the manufacturer when assembling the car.

The insulating cover on the radiator lining is designed to protect the cooling system and, first of all, the radiator from intense cooling. To adjust the overlap area of ​​the radiator surface, flap valves are used, held by latches in the required position.

The cover is recommended for use at ambient temperatures below -10 ° C. The cover is installed outside the radiator lining and fastened at the top with hooks for the hood lock bolts, and at the bottom - with a ring on a rubber cord for the brackets supporting the electrical wires going to the headlights.

To maintain the most favorable thermal conditions for the operation of the engine and the cabin heating system, it is recommended to open the valves diagonally depending on the ambient temperature. In this case, the right (in the direction of the vehicle) valve should open the inlet in the ventilation duct to the cab heater. This ensures a constant supply of fresh air into the cab.

Insulated cover on the hood is designed to reduce the intensity of cooling engine compartment when operating vehicles in winter in areas with ambient temperatures below -40 ° C. The insulation is placed on the hood and fixed on it with metal plates covering the edges of the hood. In the rear part, the insulation is pressed with a cotton belt with hooks at the ends, hooked to the fastening of the brackets of the rear side-view mirrors.

A tow hitch is a towing device designed for transporting trailers or trailers with a car. TSU is installed on many vehicles by the manufacturer. However, some motorists mount these elements on their own. Before performing the installation, you need to know what the requirements of the traffic police are for the towbar in 2019.

Towbar on a car, has several types:

  • Welded.

Attaches firmly to the vehicle. Most dangerous for participants traffic, its use on passenger cars is prohibited.

  • Folding.

This device has hinges in its design, thanks to which the device is easy to fold and put away under the car bumper. Some companies produce electrically operated folding towbars, which are controlled directly from the passenger compartment.

  • Removable.

TSU is installed by snapping a special lock. Removable towbar is the safest towing device for operation. The part is easy to install and also easy to remove, so this type of hitch is popular with motorists.

When choosing a TSU, it is necessary to take into account the dimensions of the part. Otherwise, the vehicle may not be allowed to operate.

Can it be installed on a car

The law does not prohibit the installation of a tow hitch on a car, but this is a design change vehicle that need to be legalized. Otherwise, the driver is punished by the traffic police.

Modified trunks and towbars will be approved by the traffic police. This is done so that the changes made to the design of the car do not threaten the safety of the driver and other road users. When installing the TSU on your own, you should take into account the requirements of the rules of the road regarding the installation of additional equipment on the vehicle.

Legal installation rules

The provisions for installing the towbar and its subsequent registration with the traffic police are regulated technical regulation"On the safety of wheeled vehicles" TR TS 018/2011. This traffic rule entered on January 1, 2015.

If the manufacturer has provided places for attaching the tow hitch, and also included this equipment in the list of additional devices for the machine, then its installation is not a change in the design of the vehicle and does not require registration. However, when checking, the inspector will need to present a passport for the towbar, and its certificate of conformity.

If the car is converted on its own, then for this, it is necessary to obtain the appropriate permission from the traffic police. Otherwise, the car will not be allowed for operation, since its use without a trailer will reduce the safety of other road users. Therefore, after making changes, they are put on record.

After the conversion, you will need to carry with you the TSU passport, a mark on its installation, a copy of the certificate of conformity, as well as an act of work done.

When is installation prohibited?

The legitimacy of operating a car equipped with a towbar is regulated by employees of the State Inspectorate for Road Safety. If optional equipment installed on a car not according to the rules, or poses a potential threat to the life and health of road users, then a driving ban is imposed on such a car. In accordance with the traffic rules, a car with trailed equipment cannot be used if:

  1. The installation was not carried out according to the rules, serious interference was made in the design of the car. When installing traction devices, not provided by the vehicle manufacturer, the part is connected to the car body by welding or self-tapping screws, the holes for which are made independently. However, this is prohibited by traffic rules.
  2. The hitch protrudes strongly beyond the bumper. This poses a threat to vehicles driving behind, in a collision, the vehicle behind will receive much more damage.
  3. The inability of the machine to tow trailers or trailers. Each car has a maximum load capacity, on some models, manufacturers do not provide for the use of trailers or trailers. Installing a towbar, and using it for its intended purpose, can reduce the life of the car, and lead to emergency situations.
  4. Absence necessary documents. Provided that the installation and type of trailer equipment complies with the rules, you need to acquire the relevant documents and put changes in the design into account. Otherwise, such tuning will be considered illegal.

Required documents

After registering the converted car, the motorist receives a number of documents that he needs to have with him to confirm the legality of the installation of the TSU:

  • Certificate of conformity for towbar.

Changes are approved by the state traffic inspectorate. After successful registration with the traffic police, the driver receives a certificate of registration of the modified vehicle.

  • Certificate of completion.
  • Passport for traction additional equipment, with a note from the car service where the installation took place.

Also in the glove compartment there should be a driver's license, documents for the car and the TCP, notes on the passed technical inspections are entered into it.

If the driver refuses to register changes in the design of the car, then an administrative fine is imposed on him.

fines

At self installation TSU, you need to know what punishment awaits the driver for using a traction device without registration. Violation is punishable by a warning or a fine.

Installing an additional traction device on the machine allows you to use the vehicle as a tractor for trailers and trailers. However, installation must be carried out in accordance with all the rules. Only in this case it will be possible to avoid constant fines, and harm to the life and health of other road users.

Regardless of the types of road trains, traction coupling devices must provide:

Reliable connection of a tractor with a trailer or semi-trailer;

The possibility of their relative movement;

Smooth transmission of forces from the tractor to the trailer when starting off;

Possibility of fast coupling and uncoupling.

An automobile towing device (TSU) can be represented as a combination of three elements:

Detachable coupling mechanism;

Shock-absorbing device;

Mounting details.

Traction-coupling devices of vehicles-tractors. The main classification feature of the node is the design of the main mating pair.

According to this parameter, towing devices are divided into

Hook (pair: hook - loop);

Pivot (pivot - loop);

Ball (ball - loop).

An additional classification feature is the type of elastic element. To reduce dynamic loads, cylindrical or ring springs, as well as rubber dampers, can be used. In trucks, hook and pivot devices have become widespread. On cars manufactured in Ukraine and Russia, as well as in the USA, England and France, hook-and-loop connections are used. The pin-loop connection is used in Czechoslovakia, the GDR and the FRG.

Hitch-hitch of KAMAZ 5320, 55102 hook-and-loop type vehicles is installed in the rear cross member of the frame. The stalk of the towing hook 15 is inserted into a massive cylindrical body 2, on the one hand closed with a protective cap 1, and on the other - with a cover 19 of the body. The rubber elastic element 5 is located between the two supporting flanges 20 and 21. The presence of the rubber elastic element softens shock loads when starting the car with a trailer from a stop and when driving on uneven roads. On the finger 17, a latch 14 of the hook is installed, locked by a pawl 9 and a cotter pin with a chain 11; this prevents the trailer tongue from disengaging from the hook.

The towing device of the KAMAZ 53212 car of the kingpin-loop type (Fig. 3) is a V-shaped catcher 15, which is fixed on the rear cross member with the help of an elastic flange 11 and a castellated nut 12. Depreciation is carried out by two rubber buffers 14 located on both sides of the rear cross member 10 of the frame.

An actuator with a self-release fuse 4 is fixed on the catcher. In the guide cavity of the body 6 there is a pin 5, which is fixed in the uppermost position by a lever 7 fixed on the axle 8.

When the hitching eye of the trailer drawbar hits the kingpin, the latter rises and releases the lever, which, under the action of the springs, returns to the lower position and lowers the kingpin into the opening of the coupling eye. At the same time, the self-release safety device leaves the fixed position and locks the king pin.

In order to improve safety and speed up the process of coupling a car with a trailer, semi-automatic towing devices are increasingly being used abroad.

Two-axle and multi-axle trailers have devices for turning the front axle. The articulation between the car and the trailer and the presence of the pivoting front axle of the trailer ensure the rotation of the car and the trailer without slipping the wheels, as well as the relative movement of the car and the trailer in the vertical and horizontal planes.

Depending on the method of transmission of horizontal forces, rotary devices are divided into pivot And pivotless.

The most common at present is the pivot swivel device, which has a number of disadvantages, including bulky design and high starting resistance when turning.

The pivotless swivel found on most of the new two-axle trailers does not have these drawbacks. An inner clip is fixed on the trailer frame, and an outer clip is fixed on the trailer pivot axle frame. Steel balls are placed between them. Disassembly rotary device and its lubrication is carried out through plugs.

Traction-coupling devices of road trains-dissolutions. Depending on the type of hitch with a tractor vehicle, trailer units for long loads are divided into drop trailers, drop semi-trailers and long-wheelbase drop trailers with a front rolling cart. Trailers-dissolutions are towed by cars that have horses instead of platforms, semi-trailers-dissolutions are towed by truck tractors, and long-wheelbase trailers are towed by ballast tractors. At the same time, trailers and semi-trailers-dissolutions, depending on the carrying capacity, can have from one to three axles.

Trailers - and semi-trailers-dissolutions consist of a frame, a drawbar with a loop or a pivot (semi-trailer), an axle (axles) with wheels, a bunk and a suspension. Some dissolution designs are equipped with a wheel steering system. The drawbars of the trailers-dissolutions end in a loop and are connected to the tractor with a hook. In front of the semi-trailer-dissolution there is a kingpin and its connection with the saddle of the tractor vehicle. The magnitude of the load on the trailer or semi-trailer-dissolution (for a given mass of cargo) varies depending on the length of the drawbar and the size of the overhangs of the cargo from the bunk. The designs of the bunk trailer-dissolution and the traction vehicle-tractor are the same. They consist of a transverse swivel beam and vertical tilting uprights.

Traction-coupling and supporting devices of truck tractors. The most common coupling device for truck vehicles - tractors and semi-trailers consists of a saddle located on the vehicle frame and a kingpin on the semi-trailer.

To ensure the mutual movement of the vehicle-tractor and the semi-trailer, modern fifth wheel coupling devices on the vehicle-tractor have two rolling axes (transverse and longitudinal) and a king pin rigidly fixed to the semi-trailer. Such a semi-automatic fifth wheel with two swing axes (Fig. 4.3) has the following device. On the frame of a tractor vehicle with an offset relative to rear axle(inside the base by 50-150 mm) a plate 8 is installed with a support circle 4 hinged on it, having a mouth 19. The support circle fixed on the balancer 2 can swing on the axis 3 in the longitudinal, and on the axis 7 in the transverse planes. To dampen the swing of the circle in the transverse plane, there are two cylindrical springs 6 and limiters 5. In the center of the support circle, the kingpin grips 18 are fixed, hinged on the fingers 17 and having bevels in the front. The bevels in the back of the grips coincide with the bevels: the mouth of the reference circle. In the front part, the grips have shaped cutouts into which the lock 15 is inserted. The lock has a rod 13 on which the spring 14 and the lock lever 16 are put on. The lock has a longitudinal cutout, which includes a guide pin 12. fixed at the bottom of the support circle. When the semi-trailer is connected to the tractor vehicle, the grips 18 are brought together and cover the semi-trailer kingpin. In this case, disengagement is impossible due to the fact that the lock 15 prevents the rotation of the grips on the fingers 17.

The uncoupling of the semi-trailer is carried out by retracting the fuse to the side of the bar 1 and moving the lock 15 forward using the lever 16. In this case, the spring 14 is compressed. The latch 11 in the lock, pulled by the spring 10, abuts against the lug of the lock and holds it in the forward position.

Lecture 5

Lots of modern cars are not equipped with a towing device, which sometimes creates a large number of inconveniences. The tow hitch is designed to expand the functionality of the vehicle. This mainly refers to the movement of goods and additional vehicles.

In this article, we will try to understand what trailing devices are, what they are, and also outline their features, characteristics and capabilities.

1. What is a hitch


The towing device has several names, including the towing device, as well as, by all famous name- hitch. A towbar is a device that is designed for towing cargo and light trailers using a tractor.

In other words, tow hitches are designed to securely attach a trailer to a vehicle while distributing the load correctly.


Moreover, the towbar must ensure safety and reliability during transportation, as well as not damage appearance vehicle.

An interesting fact is that the true origin of the word hitch has not been established. Many believe that it is of German origin. However, it can be found in German terminology in the meaning of the working part of a railway rail. If you combine two German words, such as ride and head, you can get the sound of farkopf, where the abbreviation towbar comes from. One way or another, this is one of the explanations for the existing word.

Another meaning of the word hitch is a device on a horse-drawn cart, which was intended for hanging luggage. There is another version of the origin of the word hitch, which presumably comes from the German word "vorkopf", which means before or before.

In any case, the word has become so commonplace that some drivers don't even know it means tow hitch.

2. Types of trailers, their advantages and disadvantages


More recently, on cars that have the properties off-road a towing hook was installed as a tow bar, to which the trailer drawbar was hooked. The main disadvantage of this device was that shock overloads occurred during transportation, which led to a quick exit from the operation of the hook. Moreover, the hitch itself assumed a number of difficulties.

Modern tow hitches have the form of a ball, with a radius of 25 millimeters to 58.702 millimeters. In this case, the trailer drawbar is also equipped with a corresponding coupling head. The advantage of modern trailers is the possibility of taking traction, braking and upper forces, if the trailer is equipped with one axle.

Towbars for cars can be divided into types, depending on the type of construction, method of attachment, as well as the maximum permissible load. Also, towbars are divided into groups, depending on the type of ball. Among them, the most common are towbars with a rigid welded joint of the ball mechanism. These devices are installed on the car on a permanent basis. This may be inconvenient if the car executive class, and the hitch spoils its appearance.

There are also towbars with removable balls, manual removable devices (the hook in the form of a ball is clamped with bolts), as well as semi-automatic (the hook is fixed with a special lever). There is also a separate type of towbars - this is a towing device for walk-behind tractors.


In general, the hitch consists of two elements - the hitch ball (on the car body) and the hitch head (for mounting on the trailer drawbar). Among other things, attention should be paid to specifications hitch. Also, when choosing a towbar, you need to know the model, release date and body type of your car. It is also necessary to know maximum weight the trailer itself.

3. The appearance of the first car trailers

The history of the appearance of the first car trailers goes back to the time of the appearance of the first trucks and dates back to the 1880s, although the facts indicate the use of the first steam tractors as early as 1853.

In general, the Austrian company is considered the main developer of the first trailers. Wilhelm Schwarzmuller, which since 1870 has been developing and manufacturing wagons and agricultural machinery. In 1921, the first trailer for a truck was produced, and in 2012, the production of semi-trailers began.

One way or another, the production of trailers was based on the needs of the army during the First World War. With the onset of peacetime, they began to gain popularity in everyday life.

4. The cost of towing devices for trailers and their manufacturers


To date, it is not difficult to purchase a towbar. In order to purchase a high-quality and reliable towbar, you must be guided by some rules, namely:

Make sure you have certificates of conformity;

Specify several times the technical characteristics of the towbar, equipment and delivery time.

It is no secret that the more questions you ask, the more information you will have. And the more information, the more chances to choose a quality product.

A large number of manufacturers, mainly European ones, are represented on the modern market of towbars. The largest and most popular are:

Thule- is considered the oldest and has been operating on the market for over 50 years, and in 2006 this company absorbed a brand such as Brink. The company also has the largest model range towbars and manufactures removable, welded and conditionally removable devices;

Auto Hack is a Polish company and has been operating on the market since 1976. The lineup about 700 models;

Bosal differs in a variety of types of towbars, from vertically removable to flange. They also make premium towbars.

The estimated cost of a quality tow hitch ranges from $50 to $110. There are, of course, budget devices, the cost of which does not exceed $ 10, but their quality and reliability are very doubtful. Prices depend on the manufacturer, the brand name, the functionality of the device, as well as its technical characteristics.

The purchase of a tow hitch will allow you to expand the capabilities of the car and supplement it with useful equipment. Before purchasing the selected towbar, compare prices from different sources. The easiest way to do this is on the Internet, so you do not spend extra time visiting car dealerships and services.


Also, it is worth indicating the purpose of the towbar. If you do not plan to use it often, you should not spend big money and choose popularized brands, but if the towbar is necessary for frequent use and transportation of heavy loads, preference should be given to well-known companies that have established themselves in the market not only as stable, but also reliable and quality manufacturers and suppliers.
