Introduction

For a number of reasons, road transport in Russia is becoming increasingly important. Cars are widely used in all areas of the national economy and perform a significant amount of transport robots, or rather serve to transport goods and passengers.

Cars have a wide range of applications in various fields and different climatic conditions and are therefore subjected to various loads. Therefore, the technical condition of the car during long-term operation does not remain unchanged. It deteriorates due to wear of parts and mechanisms, breakdowns and other malfunctions, which leads to a deterioration in the performance of the car. The main means of reducing wear of parts and mechanisms and preventing failures of the car, i.e. maintaining it in proper technical condition is timely and high-quality maintenance. Maintenance and TR labor costs are very high and account for 91 percent of all costs. Timely and high-quality performance of all work related to the maintenance of the car will increase its service life without major repairs, which will affect the amount of work performed.

The technical condition also depends on the storage conditions of the car.

For performance of objectives it is necessary to use widely means of technical diagnostics, as much as possible to mechanize production sites and shops of the maintenance (M) and maintenance (M) of cars, to equip them with hoisting-and-transport mechanisms and control and adjusting devices, to improve technology of M and TP and production management, to create the required production and household and sanitary and hygienic working conditions of repairmen.

Knowledge of all factors and patterns of changes in the technical condition of cars allows you to correctly organize work to increase the reliability and durability of the car through timely and high-quality maintenance.

Maintenance of rolling stock in terms of periodicity, as well as labor intensity are divided into the following types: daily maintenance (ES); first maintenance (TO-1); second maintenance (TO-2); seasonal maintenance (CO).

EO includes inspection work, filling with fuel, oil and cooling liquid, and for some types of specialized rolling stock - sanitary treatment of the body.

With long-term operation, cars reach a state where the cost and labor associated with keeping them operational in the conditions of motor vehicles becomes more the profit that they bring in operation. This technical condition of cars is considered to be the limit, and they are sent for major repairs to car repair enterprises.

The organization of car repair in our country is constantly paid great attention.

To better meet the increased need for automotive repair. In the rear, new ones were opened on the basis of some industrial enterprises: repair plants, as well as mobile repair units for current and major repairs of cars and their units in the field.

Much attention is paid to the training of scientific and engineering personnel in car repair. In 1930, the Moscow Automobile and Road Institute was organized, in which the Department of Automobile Production and Repair was created. The same departments in subsequent years were organized in automobile and road institutes in the cities of Kiev, Kharkov, Omsk, Tashkent and in many polytechnic institutes of our country. Currently, road and motor transport technical schools produce highly qualified specialists in the operation and repair of cars.

Car repair production in our country is constantly developing and improving. The current course on the concentration of overhaul of cars in the production associations of the automotive industry will allow to enlarge and specialize enterprises.

At large specialized car repair enterprises, conditions are created for the wide use of the most advanced technological processes, modern equipment, mechanization and automation. This master direction in the development of car repair production will lead to a sharp improvement in the quality of car overhaul and the fullest realization of its economic benefits.
