During operation, the units of individual components of the car wear out. In this regard, operational characteristics are also changing. Clearances between elements may increase, material consumption may increase, and driving performance may decrease. Maintenance can reduce wear, thereby increasing the life of the elements of the car.
But sooner or later, the time comes when maintenance is not enough to maintain the health of the vehicle. Have to resort to repair. That is, troubleshoot and restore all of its working nodes. For this, parts are replaced or repaired. In the article, we will talk about what types of car repair are, how they differ from each other.
Army system
In the army there is a system in which it is customary to separate the current, medium and major repairs. During operation, all parts wear out unevenly. Some are faster, others are slower. Depending on how many kilometers the vehicle has traveled, the technical condition of the machine and the amount of work to maintain and restore it in good condition depends. Let us consider in more detail all types of car repair.
Maintenance
In this type of repair, it is necessary to replace and repair worn or damaged parts. We are talking about individual elements that have reached extreme wear, or have already refused to work elements, except for the basic ones. That is, the following are not subject to current repair:
- cylinder block in the motor;
- rear axle - in the gearbox;
- carter - in the steering gear;
- suspension cross member or front axle beam;
- case - in the back;
- longitudinal beams - in the frame.
During the current repair, parts, individual units and assemblies are changed and restored. Other operations for troubleshooting are also possible.
Medium Repair
If more complex work is expected, then other types of car repair will be required. The middle option includes the replacement or restoration of damaged components, assemblies and individual elements with checking the technical condition and eliminating all other malfunctions identified during the inspection. Special maintenance work is also being carried out. Medium repairs include the replacement of two or more units. But their total number should not exceed half the base.
Overhaul
The main types of car repair include overhaul. It is carried out to restore the health of the vehicle. At the same time, any parts, including the basic ones, are changed and restored. If an overhaul of the unit is carried out, this ensures its full restoration, in accordance with the technical conditions. Assembly and testing are carried out in compliance with the norms and rules of maintenance. The unit is sent for overhaul in cases where the base part must be restored. If it is not possible to repair and restore it through routine repair, it is completely disassembled.
Overhaul restores the performance of the unit, according to the technical conditions for repair, assembly and testing. It is done upon reaching the established mileage or subject to the rules of maintenance, maintenance and operation. These are the main types of car repair. A few more words are worth saying about the capital option.
Capital types of car repair and their characteristics
Overhaul, among other things, is depersonalized and impersonal. In the latter case, all parts are to be installed on the object from which they were withdrawn for work. Then a certain harmony of details that has already been achieved is maintained. In this case, the quality of the repair, as a rule, increases compared to the depersonalized option. Thanks to this approach, other parts will also become more durable.
However, all types and methods of car repair are not without flaws. So, in an unbiased version, the organization of work is significantly complicated. As a result of this, the vehicle will be in the workshop longer. In addition, the work may include the replacement of parts that cannot be repaired with new units or assemblies removed from another vehicle.
In an anonymous version, the organization of repair work is less complicated. Therefore, the object will not be in the workshop for as long as in the previous case. Time is saved due to the fact that vehicles "do not wait" until parts of them are repaired. The method is highly effective, thanks to the correct general approach, the main goal of repair work and the choice of the most effective procedure for their implementation in the organizational conditions of automobile operation.
When is the best time to repair?
In our country, a preventive maintenance system has been adopted. In this case, the work is based on the established plan in order to prevent an emergency failure of one or another mechanism during the operation of a motor vehicle. Scheduled repairs involve maintenance, thus providing information on the condition of the vehicle. At the same time, planned repairs are being carried out.
The essence of the warning system is to carry out repairs until the complete wear of the main and basic parts, components and assemblies. Thus, significantly increases the safety during the operation of vehicles. After all, the use of elements at a stage close to complete wear significantly increases the risk of an accident. On the other hand, much greater financial costs are prevented. After all, repairs carried out only in case of failure in the operation of a particular unit, as a rule, are much more expensive than the one which was carried out in advance.
As you can see, the types of car repair presented in the article have their purpose. Their use depends on the technical condition of the vehicle, as well as on the work planned for a certain period of time.
