Powertrain suspension (VAZ-2109)

            0

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

The vehicle has a three-point powertrain mounting system, consisting of a front 5 (figure 11), rear 2 and left 3 supports.

1 - rear suspension bracket; 2 - rear suspension support; 3 - left suspension support; 4 - left suspension bracket; 5 - front suspension support; 6 - front suspension bracket.


The front and left supports have the same design and consist of an outer steel collar 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 fastened with bolts to the cylinder block, and bracket 4 of the left support is fastened with studs to the gearbox housing. The supports are fastened to the body brackets with bolts that pass through holes in the support bushings.



The information can be read on the website (www.vazbook.ru)

The rear support 2 is bolted from below to the body bottom. It consists of external steel reinforcement and an internal aluminum bushing, also separated by rubber. The rear support bracket 1 is forged steel and is fastened to the gearbox with bolts connecting the clutch housing to the gearbox housing.
