Introduction

Maintenance of machines is a set of preventive measures during the overhaul period aimed at preventing failures in units and assemblies and reducing the intensity of wear of parts. Maintenance includes control and diagnostic, fastening, lubrication, filling, adjusting, electrical and other types of work.

Car maintenance has the goal of: ensuring the constant technical serviceability of units, components in the car as a whole; maximize overhaul runs; guarantee traffic safety; ensure the minimum consumption of operating materials.

To achieve these goals, a planned preventive maintenance system has been adopted in our country, which provides for the mandatory implementation of the established set of works at a given frequency in the process of using, storing and transporting vehicles. The technological process of servicing a car with a planned preventive system provides for a combination of mandatory work with work performed on demand, the need for which is determined as a result of checking the condition of the car. Maintenance of special equipment installed on the vehicle is carried out, if possible, simultaneously with maintenance of the chassis.

Depending on the amount of work and the frequency of their implementation, maintenance is divided into the following types: control inspection, daily maintenance, maintenance No. 1 (TO-1), maintenance No. 2 (TO-2), seasonal maintenance (SO). The objective of this course project is to get acquainted with the system for carrying out vehicle maintenance, draw up a technological map, determine the number and placement of workers, and also carry out the selection of technological equipment. Carry out a drawing of the car in two projections indicating the number and place of the maintenance operation. And the technological layout of the post with the arrangement of equipment and workers.

TECHNOLOGY CARDS FOR MAINTENANCE AND REPAIR OF KAMAZ VEHICLES (1989)

Introduction
Technological maps of the current repair of units were developed by Tsentravtotekh of the Ministry of Aviation Transport of the RSFSR at the request of the production company KamAZavtocenter of the production association KamAZ.

Technological maps are developed on the basis of the following materials:

1. Regulation on the maintenance and repair of the rolling stock of road transport. Part 1 (guidance).

2. Regulations on the maintenance and repair of the rolling stock of road transport. Part 2 (normative). Cars of the KamAZ family. Po-200-RSFSR-12-0115-87.

3. Operation manual for KamAZ vehicles of 6x4 type (5320-3902002P7).

4. Operation manual for KamAZ vehicles of 6x6 type (4310-3902002RE).

5. Guidelines for the current repair of KamAZ-5320, KamAZ-5511, KamAE-4310 vehicles (shop works). RT-200-15-0066-82.

6. Catalogs and drawings of parts and assembly units of KamAZ vehicles.

When developing technological maps, equipment, instruments and tools were used, which are serially produced by the factories "Rosavtospesoborudovanie" and non-standard equipment, including those developed at KamAZ.

Technological maps contain standards for the labor intensity of work, agreed with the "Tsentro-rgtrudavtotrans" of the Ministry of Transport of the RSFSR.

Technological maps have passed experimental approbation.

Technological maps are typical. In each individual case, it is necessary to link them to the specific conditions of enterprises.

The nomenclature of the repaired units, assemblies, mechanisms and devices was selected based on the typical and most frequent works on the current repair of KamAZ vehicles at enterprises.

The list of technological maps includes repair of: engine, fuel equipment, gas equipment, electrical equipment, pneumatic equipment of the brake system, dumping mechanism, transmission.

To facilitate the reading of technological maps, they contain diagrams, drawings.

The technological maps contain a complete list of disassembly, assembly and troubleshooting operations. Under operating conditions, the depth of disassembly and the scope of troubleshooting can be carried out until a defect is detected.

When organizing and performing work on the current repair of units, assemblies, mechanisms and devices, it is necessary to be guided by the system of labor safety standards and the "Safety Rules for Road Transport Enterprises".

Routine repairs of units, assemblies, mechanisms and devices should be carried out in the workshops or areas designated for this.

When disassembling units, assemblies, mechanisms and devices into parts, it is necessary to use pullers and devices that facilitate the work of performers and ensure the safety of work.

Workshops for the current repair of units should be equipped with the necessary lifting and transport mechanisms. Aggregates and assemblies with a significant mass should be transported, removed and installed from stands with the help of lifting and transport mechanisms equipped with devices that protect from possible falling of aggregates and assemblies.

Devices for fixing units and assemblies on stands should exclude the possibility of displacement or falling of assemblies and assemblies. Tools and fixtures must be in good condition.

The procedure for carrying out routine repairs is set out in technological maps, which reflect the sequence of disassembly and assembly, defect inspection and testing of units and assemblies, equipment, fixtures and tools, technical conditions and instructions, labor intensity of work and qualifications of performers.

The technological process of the current repair of the units should include: cleaning and washing work on the car; identification of faulty units on the car; removal of faulty units from the car; transportation to the workshop; disassembly; external sink (cleaning); disassembly;

washing; cleaning, drying, blowing parts; troubleshooting; picking; assembly; test adjustment; ■ acceptance by quality control department; transportation to the post (warehouse); setting on the car.

Only persons who have been instructed in safety precautions and trained in safe working practices in special classes organized by the administration of the enterprise are allowed to work on the repair of units, assemblies, mechanisms and devices.

In workshops or in areas, there must be first aid kits, complete with medicines necessary for first aid.

The acceleration time from 0-100 is 13.5 s. The maximum speed is 165 km / h. Fuel consumption in urban mode is 10.1 liters. per 100 km., on the highway - 6.7 liters. per 100 km., and in the combined cycle per 100 km - 7.9 liters.

All versions in three versions have:

The same base at 2905 millimeters;

The track of the front and rear wheels, respectively, is 1469 and 1466 millimeters;
