How is the engine support and what is it for?

The internal combustion engine and gearbox are the two most important units in the car. In the absence or non-working condition of at least one of them, it is already impossible to make a full-fledged movement on the vehicle. In each car, the engine and transmission are fixed in the engine compartment on special supports that prevent them from swinging and deforming.

The engine support is a special rubber-metal assembly, which, despite its simple construction, plays a significant role in the car's operation. What is noteworthy, this mechanism performs several very contradictory characteristics at once. On the one hand, the motor support maximally fixes the power unit to the body of the vehicle, and on the other hand it softens the transmission of the motor vibrations to the other parts. Thus, this device does not allow the unit to move and at the same time prevents the transmission of vibrations that are created during its operation.

To ensure that the power plant does not move from the mountings, the engine support must be as strong and durable as possible. For this, the basis of this mechanism is a metal structure, on the outside of which there are rubber cushions. They reduce all the vibrations, and also absorb the engine when the car hits the unevenness.

The support must be manufactured according to special requirements, which can only be calculated on the factory equipment. Therefore, so that the motor does not move In the longitudinal and transverse directions, the manufacturer carefully controls the properties of the rubber cushion and its metal base. Ideally, this part should not be very soft, as with excessive cushioning the unit is highly swinging, which leads to a decrease in the controllability of the car and the large wear of the tires on the driving wheels. When you hit a bump, this engine support also provokes involuntary shutdown of gears.

Now almost all modern cars are equipped with gel or hydraulic supports. At the top of these parts is an oily liquid. The latter reduces vibrations and acts as a shock absorber.

As for the service life, a regular engine support can last about 50 thousand kilometers. After reaching There is noticeable vibration in the interior of this mileage . This indicates that the front and rear engine mounts have become unusable. But when buying, you should not bypass the so-called tuning details. Despite the fact that in the domestic market they appeared only a few years ago, their characteristics deserve general attention. To verify the quality of such details, it is enough to simply read the reviews of car owners who purchased them. Thanks to the tuning support, the car has more even acceleration and better grip on the road. There is also a large traction force on the rear wheels. The car behaves confidently on the road, especially it is felt on corners. And they cost from 1000 to 1500 rubles; Regular parts - up to 900 rubles.
