7.2. A mechanical transmission

7.2.2. Introduction

The transmission is placed in картере from an aluminium alloy and attached to the left end of the engine. It consists of a transmission, the main transfer and differential.

The twisting moment from a cranked shaft of the engine is transferred through coupling to a primary shaft of a transmission on which the coupling disk is established. The forward part of a primary shaft is established on the roller bearing, and a back part – on the ball tight bearing. From a secondary shaft the twisting moment is transferred to differential and to power shafts.

In neutral position a primary shaft and gear wheels of a secondary shaft rotate freely and do not transfer a twisting moment to differential.

The gear change mechanism is put in action by the lever located on a floor of the car, by means of a switching rod. The gear change mechanism moves a corresponding plug which moves the synchronizer and provides rigid connection of a gear wheel of a secondary shaft with secondary shaft.
