1. The role of vehicles in the national economy

Road transport is one of the most important branches of the national economy. There are practically no enterprises of industry, construction, agriculture that would not use the services of vehicles. Its role in meeting the transportation needs of the population is great.

Motor transport is the most mobile of all existing modes of transport. It does not depend on the availability of main roads and with the help of it daily transport links between enterprises, institutions, organizations, between them and other modes of transport, etc.

Road transport plays an important role in the work of the country's transport and road complex. The advantages of road transport are high maneuverability, high carrying capacity, faster delivery of goods and passengers, lower cost of short distances compared to water and rail transport, and some others. Due to high maneuverability, road transport transports goods directly from the consignor's warehouse to the consignee's warehouse without expensive transshipments from one mode of transport to another. Higher speeds on improved roads make it possible to deliver goods and passengers more quickly than on waterways and railways.

The share of road transport in transportation is constantly increasing. More and more goods transported by rail over short distances are transferred to the road, even if there are access railways at the sender and recipient.

In the total volume of cargo transportation carried out by all modes of transport in the Russian Federation in 2009. The share of road transport is 54.6%, and in passenger transportation - 53.7%. These figures undoubtedly speak for themselves that automobile was and remains one of the most important modes of transport.

2. Value of repair production

The most important condition for the high-performance and uninterrupted operation of the rolling stock of road transport is the provision of its modern production and technical base for the overhaul of cars, units and the restoration of worn out parts. The main tasks of repair production are the further development of centralized repair of machines and equipment as the most important prerequisite for the introduction of progressive technological processes that ensure an increase in the quality and efficiency of repair of complex modern equipment.

The prospects of car repair production are determined by objective constantly operating factors. Modern design, technological and economic foundations, on which the design, production and operation of cars are based, determine the disparity in the resource of individual parts of units and assemblies and make their simultaneous replacement impractical.

During the operation of the car, its structural elements are subjected to physical wear under the influence of friction forces and the environment. In order to keep cars in working condition, it is necessary to systematically carry out a whole range of measures, including maintenance, maintenance and overhaul with periodic replacement and restoration of worn out parts and assemblies.

Environmental protection activities

From the farm workshop, all waste is exported to the district landfill on the territory of the farm itself, the so-called forest plantations are planted every year. In order to preserve the environment, it is necessary to carefully study the issues of neutralization, disposal or burial of various harmful solutions of acids, alkalis, detergents and other materials used during repair together with the district sanopedemstation. Spent lubricants are sent for regeneration or used for local needs. Some repair processes, such as painting, epoxy resin applications, storage, welding, and some others, are associated with the release of harmful or toxic gaseous media. Devices for forced exhaust ventilation with outlet pipes of sufficient height shall be provided at all places of possible release of such substances.

Conclusion

I designed the washing area in the conditions of a motor transport enterprise. This area is designed for cleaning vehicles, as well as work related to cleaning cars. The site has an area of ​ ​ 45kv. meters, and designed to serve cars.

This site is located in a production building, which includes all sections and workshops, which will reduce the cost of construction and further maintenance. The building itself is equipped with the necessary number of rooms, corresponding to the technological process.

One person works at the site. The area is provided with the necessary amount of equipment. At workplaces there are instructions and job descriptions and memos.

On the site with natural lighting is provided and artificial.

In the technological part of this diploma project, he considered issues of repair of the camshaft, main defects, methods of their repair. Then he developed a defect map, indicating repair methods.

For better cleaning of cars, the device "Nozzle for washing" was developed. Working documentation for its manufacture (specification and detailed drawings) was made and developed for this device.

In the graphic part, he provided a plan for the washing area, with the arrangement of technological equipment, with the application of the necessary dimensions and observance of fire safety. And assembly drawing of accessory, working drawings on accessory parts.
