3.1 Introduction

In conditions of increasing volumes of passenger traffic, maintaining buses in a state of high operational reliability with minimal labor and material costs and creating labor safety for traffic and environmental conditions is the main goal of all services of the motor vehicle enterprise.

The efficiency of road transport in transport depends primarily on the level of technical readiness of vehicles. In this regard, the role of high-quality diagnosis and qualified repair of vehicles becomes especially great.

Assembly and assembly works during the repair of rolling stock at Convoy No. 1375 are among the most time-consuming and least equipped with modern equipment. In this regard, one of the main tasks of the development of automotive repair production at the enterprise is to increase the level of mechanization.

The main defects of gearboxes are cracks and cracks of the crankcase, wear of gear teeth, holes for bearings and the bearings themselves. To eliminate these defects, a significant amount of disassembly, welding and other work is required, which requires the use of special devices

Conclusion

During the analysis of the production and technical base of the State Unitary Enterprise MO Mostransavto, the branch of convoy No. 1375 revealed inconsistencies in the resulting economic result, the composition and size of the bus fleet. In this regard, the goals and objectives of the project were formulated, measures to improve the production operation of the bus fleet, and means to achieve the intended goal .

Based on calculations, it was established that the non-load of buses on routes as a result of the introduction of the information navigation system can be reduced from an average of 72 to 14%

In order to improve repair operations at the company in question, in the diploma project, a stand was developed for repairing the Mercedes Benz Sprinter 413CDI bus checkpoint. At the same time, the most common models of stands for repairing checkpoints were analyzed, their characteristics were given, the main advantages and disadvantages were considered. Calculation of bench units and elements is performed.

An analysis of the state of labor protection at convoy No. 1375 was carried out, measures were proposed to improve the state of labor protection, reduce the impact of harmful industrial factors, calculation of injury rates at work, calculation of lighting and vibration insulation

Measures are proposed to reduce the environmental burden of the enterprise on the environment, a project is being considered to modernize artificial, street lighting, by replacing mercury lamps with more economical and safe sodium lamps, an economic assessment of the event is given.

An assessment of the cost-effectiveness of improving the routes of convoy buses No. 1375 using the means of introducing an information navigation system was carried out. The payback period was 0.81 years, the estimated economic effect is 7303tys. rub.
