Designing the process of providing services at the tire shop

The design object is the tire fitting area at the service station.

Tire service is the service and repair of car wheels. Both stationary and mobile tire fitting on wheels takes place in several stages.

Tire fitting includes:

removal / installation of the wheel on the vehicle

wheel wash

diagnostics and disassembly

troubleshooting or replacing tires

mounting and balancingThis is done with a special foaming liquid. Or more simply, the tire is simply lowered into a tank of water

After determining the location of the damage, the tire is placed on a tire changer. The simplest tire changer is most often a round rotating table with special devices that can greatly facilitate and simplify tire repair. Stands exist automatic and semi-automatic.

As a material for repairing a tire, a tourniquet or patch is usually used.

Repair tubeless tire tourniquet is as follows: the location of the damage is determined, the cause of the puncture is removed, the walls of the damage are covered with glue, the tourniquet, which matches the diameter of the puncture, is also placed in the puncture hole.

When repairing a tire with a patch, the first two stages are the same as in the previous case. Next, grind the damaged area. A patch of fresh rubber is glued on it. Vulcanization is carried out, grooves are applied on the tread.

The following types of work are carried out at the tire shop:

· Tire fitting of wheels;
· Balancing;
· Vulcanization;
· Editing disks;
· Correction of tires from defects.

Depending on the method of organizing the repair and the type of tires being repaired, several types of tire fitting can be distinguished. These are long-familiar stationary workshops, and their analogue is mobile tire fitting. The latter arose due to the pronounced seasonal focus of this business, which predetermines that most of the orders will be in late autumn or early spring. But it is impossible to organize a profitable enterprise, all the rest of the time being limited to waiting for the arrival of a driver who has received an accidental puncture in the workshop. So tire fitting and became on wheels. Usually a mobile, or mobile tire fitting, is a van based on a small truck, the filling of which is a special tire fitting equipment. But in accordance with the nature of the tires requiring repair, this type of car service is divided into passenger and truck tire fitting.

Professional tire changers and high-quality consumables for tire changer are the most important difference between a serious specialized enterprise. According to its design, equipment for tire fitting and related work can be computerized, automatic and semi-automatic. It is also divided into diagnostic, balancing, painting and welding - according to the functionality.

What types of services are provided in tire shops? Wheel balancing - Car tire is a complex technical product, consisting of a large number of elements and different compositions rubber compound, as well as steel, textiles, synthetic materials. Therefore, in the production of a tire, it is quite difficult to evenly distribute the constituent elements of the tire carcass structure, and this inevitably leads to the appearance of “heavy” places in the tread part, as well as in the sidewall. In addition, the disk has a hole for the valve, which in turn has its own mass. And the technology of manufacturing disks by casting also does not allow achieving equal weight around the entire circumference of the disk.

If the wheel is not balanced, then when rotating on the car, it causes vibration, which is especially noticeable at speeds from 80 to 120 km / h. As a result, comfort deteriorates, the load on the vehicle suspension elements increases significantly, the tire wears unevenly and fails prematurely.

How is wheel balancing done? The car is on a lift. The wheels are removed and washed, after which they are checked on special equipment designed to eliminate dynamic imbalance. It is very good if the unit allows you to balance the wheels, taking into account factory tolerances in rotating elements - hubs, disks, etc. At the end, the wheels are installed on the car. In this case, the tightening force of the fasteners is controlled by a torque wrench. This is the most general scheme.

Modern equipment for tire fitting and technical diagnostics allows you to combine this important process with a number of other auxiliary technical operations.

Tire vulcanization is a type of tire repair for various damages. Distinguish between cold and hot vulcanization. Cold vulcanization is the bonding of two materials (in this case, rubber components), without heat treatment. Hot vulcanization differs from cold vulcanization in that the bonding of materials occurs using high temperatures. For this type of repair, such consumable, like "raw rubber" - a viscous, plastic mixture that turns into real rubber during the vulcanization process and closes the damage.

Repair of tubeless tires is not accidentally singled out as a separate type of repair. Tubeless tires have a long list of advantages, but the repair of such tires is a complex process that has unique technologies from which it is impossible to depart. Let's start with the fact that all installation and dismantling work must be carried out very carefully. A slight damage to the bead flanges is enough, and depressurization of a tubeless tire can occur. Repair of such a tire is carried out only on special equipment. For example, for removal and installation it is better to use a tire changer. Some of these machines are available in the TI version, with a built-in tubeless tire inflator.

Tire side cut repair is a process no less responsible than tire balancing. First of all, because the safety of driving a car depends on the observance of technology and the quality of its implementation. To repair tire side cuts, you need a specialized vulcanizer - always with bilateral heating of the tire, as well as knowledge of the features of this type of repair.

Restoration, repair and painting of disks is a service that is popular with many motorists. Very often, only a set of disks is found on sale, the purchase of which will cost more than repairing one. It is important that the repair technology does not violate the structure of the metal; it is good if during the repair of the disk its heating is excluded.

Tire inflation is a service that in many workshops becomes free for serious customers. This important procedure, the need for which does not need to be told to any motorist.

Inflating tires with nitrogen is a novelty that has managed to become popular in many car service and tire fitting points, which can pleasantly surprise all motorists and professional drivers. Nitrogen has several advantages over air. It is an inert gas and therefore there is no risk of explosion. Nitrogen has a slower leak rate, so the car gets more range in the event of a puncture. There are other advantages - constant pressure, retardation of aging, elimination of rim corrosion.

Reception of tires for seasonal storage, which is so difficult to properly organize in an apartment or a regular garage, is also becoming a service provided by some service centers, owners of suitable storage facilities.

What distinguishes a serious tire fitting organization? First of all, it is high measurement accuracy, speed, reliability and quality assurance. This becomes possible only thanks to the work of real professionals, in combination with the use of the most modern machines and tools for tire fitting.
