8.1. Manual box of gear shifting
The transmission is placed in the cast case attached to the left end face of the block of cylinders. The RKPP case is equipped with the openings for descent, check and adjustment of level of oil closed by traffic jams.
Rotation is transmitted from a bent shaft of the engine through coupling knot on primary (leader) shaft of RKPP. The main shaft is supplied with vents on which the conducted clutch plate is established. From a main shaft on which there are all leading gear wheels of transfers rotation is transferred to the secondary (conducted) shaft of RKPP on which the conducted gear wheels of all transfers are located. All transfers are synchronized. From a secondary shaft rotation via the driveshaft is transferred to the main transfer and differential from which power shafts are set in motion. Free rotation of satellites of differential on the axes allows an internal wheel to rotate when passing turns more slowly than external. Primary and secondary shaft of a box are located in parallel each other, and also parallel to cranked and cardan shaft.
Gear shifting is carried out by means of the coulisse established on a floor of salon by means of the lever mechanism of the choice of transfers. The mechanism consists of a switching set of forks by means of which the sliding couplings of synchronizers move along a shaft, carrying out blocking of gear wheels of the corresponding transfers.
