7.2. Mechanical transmission
The transmission is placed in a case from an aluminum alloy and attached by the left end of the engine. It consists of a transmission, the main transfer and differential.
The torque from a cranked shaft of the engine is transferred through coupling to primary shaft of a transmission on which the coupling disk is established. The forward part of primary shaft is established on the roller bearing, and a back part – on the ball tight bearing. From a secondary shaft the torque is transferred to differential and to power shafts.
In neutral situation primary shaft and gear wheels of a secondary shaft rotate freely and do not transfer a torque to differential.
The mechanism of gear shifting is put in action by the lever located on a floor of the car, by means of a switching rod. 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 secondary shaft.
