Introduction

Urban passenger transport plays a special role, satisfying not only the needs of production, but also the social and individual needs of society and everyone. In turn, it is an integral part of a single transport system and occupies an important place in it.

The main task of urban passenger transport is to timely, high-quality satisfaction of the needs of the national economy and the population in transportation.

The organization of urban bus transportation is one of the main tasks, the solution of which ensures the life of modern cities, the distribution of traffic volumes between individual modes of transport and the definition of the role of each type of transport should be made on the basis of the following requirements:

1. Ensuring the lowest operating costs;

2. Quality passenger service.

Analysis of work at passenger car enterprises shows the presence of certain problems in urban passenger transport.

One of these problems is the aging of the fleet and the lack of a necessary repair base .

Maintenance of cars in technically working order depends substantially on level is production technical base the enterprise of the road transport, representing set of the buildings, constructions, the equipment, equipment and tool intended for maintenance and repair of the rolling stock.

Currently, in motor transport enterprises (ATPs), the technological processes of maintenance and repair of rolling stock do not fully meet the requirements of scientific and

technical process. Improving the design of cars, their assemblies and assemblies causes the need to modernize production areas and work stations, equipping them with new technical equipment.

The shortcomings of existing technological processes, the shortage of technological equipment, lead to violations of technological discipline, low quality of work and, as a result, the premature appearance of malfunctions of rolling stock.

However, it should be borne in mind that the creation of a developed production and technical base requires a large financial cost. Therefore, the process of reconstruction and technical re-equipment should be ongoing and continuous.

Conclusion

The diploma project consists of an explanatory note, and graphic material for 10 sheets of A1 format.

During the diploma project, the following were completed:

- analysis of PATP location;

- arrangement of suspension diagnostics section;

- Calculations of labour intensity of works by sections and zones;

- required number of posts and production workers;

- required areas of industrial and domestic premises.

In the design part of the project, a stand was developed for diagnosing the suspension of the car. The electric motor and gearbox were selected, the shafts were calculated for strength.

The section "Safety of vital activity" considers harmful factors on PATP, and calculation of lighting for inspection ditch of diagnostic zone is made. The number and type of lamps and their arrangement in the inspection ditch are determined.

In the section "Economics" calculations were made: the effectiveness of the introduction of the suspension diagnostics area, profit and payback period.

Thus, according to the diploma project as a whole, it can be noted that the goals and objectives set as a result of the work carried out have been achieved.
