Power unit suspension

power unit (engine with gearbox and clutch) installed on the car on elastic supports. They perceive both the weight of the power unit and the loads that occur when the car starts off, accelerates and brakes. Elastic mounts absorb the vibrations of a running engine and do not transmit them to the body, thereby reducing noise in the car. On the other hand, elastic mounts protect the power unit from sudden shocks when the vehicle is moving over uneven roads.

The car adopted a three-point mounting scheme for the power unit, consisting of a front 5 (pic. eleven), rear 2 and left 3 supports.



The front and left bearings have the same device and consist of an outer steel cage and an inner aluminum bushing, between which there is rubber vulcanized to them. The supports are pressed into welded steel brackets. Bracket 6 of the front support is bolted to the cylinder block, and bracket 4 of the left support is bolted to the gearbox housing. The supports are attached to the body brackets with the help of bolts that pass through the holes in the support bushings.

The rear support 2 is bolted from below to the bottom of the body. It consists of an outer steel reinforcement and an inner aluminum sleeve, also separated by rubber. Bracket 1 of the rear support is forged steel, mounted on the gearbox with bolts connecting the clutch housing to the gearbox housing.
