Introduction

Road transport is the most mass and convenient mode of transport, having great maneuverability, cross-country ability and adaptability to work in various climatic conditions. Road transport is an effective means of transporting passengers and goods mainly over relatively short distances. ZIL431410 and GAZ 3307 cars are onboard trucks designed to transport piece goods from enterprises and factories to warehouses.

Vehicle maintenance is designed to maintain serviceability and serviceability during its operation, storage and transportation. The main maintenance works include lubrication, diagnostic, adjustment and fastening works. The purpose of maintenance is to prevent faults and reduce wear of parts of the car. However, during the operation of the car, it can fail, in which case repair of the car is required. Repair is designed to restore the car or unit that has lost its operability. Repair includes assembly and assembly works, as well as directly restoration work. According to the Regulation on Maintenance and Repair of Rolling Stock of Road Transport, the following types of maintenance are adopted in our country: daily maintenance (TR), TO1, TO-2, seasonal maintenance (CO) and 2 types of repair: routine repair (TR), overhaul (CR).

The main tasks facing the technical service of the motor vehicle enterprise include:

- development and delivery to the executors of regulatory and technical and design documentation ensuring creation of conditions for technical policy implementation;

- planning, organization and management of maintenance, repair and storage of rolling stock;

- organization of logistical support and storage of spare parts, operational materials;

- development of measures to save all types of resources and primarily labor and fuel-economic;

- analysis of technical condition of road transport rolling stock, production and technical base, technological equipment, production reserves;

- organization of internal calculation of maintenance and repair of rolling stock;

-Compile the delivery plan and describe the vehicles and process equipment;

- staffing of the engineering and technical service with personnel, advanced training, improvement of working and living conditions, improvement of rationing, moral and material incentives of the personnel;

- carrying out measures to prepare enterprises for the reception and effective operation of cars of a new design;

- communication, dissemination and realization of best practices of technical operation;

The purpose of the course project is to consolidate and deepen knowledge on the technology and organization of maintenance and maintenance (TR) of rolling stock, as well as technological design of production divisions of operational motor transport enterprises (ATP). In the project, the process design of the TR zone is carried out, which is an important link in the general maintenance and TR process at this ATP in Arkhangelsk

The following main tasks are solved in the course project:

- determination of scope of works and number of workers at ATP and in TR area

- development of organization and technology of works in the TR area

- composition of Job Instruction;

- calculation of the level of mechanization of the production process;

- planning decisions.

Characteristics of atp and zone tr

This road transport enterprise is an industrial cargo company, since it uses trucks ZIL431410 and GAZ3307 - onboard trucks. The freight transport company carries out freight transportation using on-board cars, dump trucks, vans, tractors, semi-trailers, trailers of various carrying capacities. In large industrial centers, where there is a large volume of the same type of cargo, freight ATPs can specialize in the types of cargo (reinforced concrete products, bulk goods, containers, products of industrial enterprises).

Cars are operated in the suburbs of the city of Arkhangelsk on roads with asphalt pavement in the cold climatic zone, flat terrain. Operating conditions category (CMS II).

The company operates 100 ZIL431410 cars and 85 GAZ3307 cars. For ZIL431410 cars, the mileage is first 40,000 km, and for GAZ3307 cars, the mileage is first 30,000 km. The actual average mileage of ZIL431410 cars is 400.0 thousand km, and for GAZ3307 cars the actual average mileage is 352.94 thousand km.

The average daily mileage of cars is 240 km.

The number of working days in the year is 305 days. Cars work in two shifts. The start time of cars entering the line in shift I is 08 00 the end time of exit 09 00. The start time of cars entering the line in shift II is 13 00 the end time of exit 14 00. The average daily working time of cars on the line is 10.7 hours.

The TR area is essential in the overall maintenance and repair of vehicles. This area on ATP is designed to remove worn-out or disabled units from the car and install new or repaired ones on the car.

Conclusion

In this course project, a project was developed for the TR zone.

In the first section, a characteristic was given to road transport and directly to the ZiL - 431410 car. The objectives and objectives of road transport maintenance and TR were identified. The characteristics of the ATP technical service were also given.

In the second section, the characteristics of this ATP and the TP zone were given.

In the third section, standards were adopted, their adjustment was made, the following were determined: technical readiness coefficient α _ t = 0.879, car usage coefficient α _ and = 0.700. Were defined: total annual run 〖∑ L 〗 _ km r=11344200; annual maintenance programs: Neo = 47268 autos.; Numr = 36396 t.; N2 = 977 t; N1 = 2935 t; Nd1 = 4206 t; ND2 = 1172 t; Bus Neo=370. Replaceable programs are calculated: 〖 N 〗 _ bus YMP^CM=60; 〖 N 〗 _ bus EO^CM=77; 〖 N 〗 _ 1^CM=10 bus; 〖 N 〗 _ 2^CM=3 bus; 〖 N 〗_ (D-1) ^CM=14 bus; 〖 N 〗_ (D-2) ^CM=4 bus.

After that, the annual labor intensity of TO and TR 〖 ∑T 〗 _ TO = 37039.09 people were determined; T _ (tp/1000km) ^ g = 107341.60 (hourly )/1000km

As a result, the number of regular workers at ATP and in the TR zone was determined: at ATP Rya = 70 people.; Rsh = 78 people; in the TR zone, RH = 20 people; Rsh = 23 people.

In the fourth section, the organization of maintenance and maintenance was defined. At this ATP, the organizational and production structure of the technical service for ATP with a number of cars from 150 to 200 was adopted. The TR process was also developed, the equipment was adopted and the production area was calculated.

In the fifth section, the technological process of removing the spring of the front suspension of the ZiL - 431410 car in the form of a job instruction was developed.

In the sixth section, the degree and level of mechanization of labor were calculated: C = 60.9%; Y = 4.87%.
