On the car the five-step mechanical transmission (fig. 6.3) is established.

The transmission is executed on двухвальной to the scheme with five synchronised transfers of a forward course and one not synchronised transfer of a backing. The transmission and the main transfer with differential have the general картер; besides, the transmission is supplied additional intermediate картером and a cover. The primary shaft запрессован in the block of gear wheels also is connected to it шлицами.

On secondary to a transmission shaft the leading cylindrical gear wheel of the main transfer, conducted gear wheels and synchronizers of transfers are established. Steams of gear wheels of a forward course of a transmission are in constant gearing. Gear wheels I–V of transfers in neutral position freely rotate on secondary to a shaft.

Transfers of a forward course join axial moving corresponding муфт the synchronizers established on secondary shaft. Backing transfer joins moving of an intermediate gear wheel of a backing along the axis.

The gear change mechanism is located in a cover established from above on картере of a transmission.

Fig. 6.4. The main transfer and differential: 1 – a shaft-gear wheel of a reducer of a drive of a speedometer; 2 – the case of a reducer of a drive of a speedometer; 3, 12, 34 – sealing rings; 4, 11, 19, 31, 37 – bolts; 5 – a lock plate; 6 – a transmission cover; 7, 33 – external rings of bearings of differential; 8 – an adjusting nut of bearings; 9 – a clamp plate; 10 – a washer; 13, 36 – epiploons; 14 – an axis of satellites of differential; 15 – a clamp of an axis of satellites; 16, 30 – conic roller bearings of differential; 17 – a lining; 18 – the bottom cover; 20 – the differential case; 21, 26 – persistent washers; 22, 25 – semiaxial gear wheels; 23, 27 – persistent washers of satellites; 24 – satellites; 28 – a conducted gear wheel of the main transfer; 29 – a leading gear wheel of a drive of a speedometer; 32 – картер transmissions; 35 – the right cover of bearings of differential

The main transfer (fig. 6.4) is executed in a kind of pair the cylindrical gear wheels which have been picked up for noise. The twisting moment is transferred from a conducted gear wheel of the main transfer to differential and further on drives of forward wheels.
