8. Transmissions

The VE transmission is placed in a case from aluminum alloy and attached to the left end of the engine. It consists of the transmission, the main transfer and differential. The transmission has five synchronized transfers for advance and one transfer of a backing. The case of the transmission consists their three parts made by casting under pressure of aluminum alloy. On cars two types of the mechanical transmission are established. Both types of the transmission are similar and work as follows.

The torque from a bent shaft of the engine is transmitted through coupling to a main shaft of the transmission on which the clutch plate is established. The main shaft is established on ball bearings. Further the torque is transferred to a secondary shaft which right end is established on the roller bearing, and left – on ball. From a secondary shaft the torque is transferred to differential and to power shafts. In neutral situation the main shaft and gear wheels of a secondary shaft rotate freely and do not transfer torque to differential.

Synchronization of 1 and 2 transfers happens on secondary to a shaft, and synchronization 3, 4 and 5 transfers – on primary to a shaft. New Process synchronizers are used. Pig-iron forks have a molybdenic covering on basic surfaces (forks of the 5th transfer are made of bronze).

The mechanism of gear shifting is put in action by the lever located on a car floor. The mechanism of gear shifting moves the corresponding fork which moves the synchronizer and provides rigid connection of a gear wheel of a secondary shaft with a secondary shaft.

The differential – classical type, has two satellites and two semi-axial gear wheels. The case of differential is manufactured of spheroidal cast iron. Rings of sliding of satellites are made of the polyamide saturated with molybdenum dioxide.
