8.1.1. General information
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 openings for descent, check and correction of level of the oil, the closed jams.
Rotation is transferred from a cranked shaft of the engine through coupling knot to primary (leading) shaft of RKPP. Primary shaft is supplied with shlitsa on whom the conducted disk of coupling is established. From primary shaft on which there are all leading gear wheels of transfers, rotation is transferred to a secondary (conducted) shaft of RKPP on which 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 actuated. Free rotation of satellites of differential on the axes allows an internal wheel to rotate when passing turns more slowly than the external. Primary and secondary shaft of a box are located in parallel each other, and also parallel to cranked and kardanny shaft.
Gear shifting is carried out by means of established on a floor of salon of the coulisse by means of the lever mechanism of a choice of transfers. The mechanism consists of a set of forks of switching by means of which sliding couplings of synchronizers move along a shaft, carrying out blocking of gear wheels of the corresponding transfers.
