8.2. General information

On the cars described in the management the 5-staged manual box of gear shifting (MBGS), or 4-or the 5-staged automatic transmission (AT) is established.

The transmission is placed in the cast aluminum case attached to the left end face of the block of cylinders. Mechanisms actually of a box of gear shifting and differential are a part of knot. The model of a box is specified on the plate fixed on its case (see the Section Identification of Transmission). The case is equipped drain, jellied and control with the openings closed by traffic jams.

Rotation is transmitted from a bent shaft of the engine through coupling knot on a main shaft of the transmission. The main shaft is supplied with vents on which the conducted clutch plate is established. From a main shaft on which there are all 6 gear wheels of transfers rotation is transferred to a secondary shaft of RKPP on which the conducted gear wheels of all forward transfers are located. All transfers are synchronized. From a secondary shaft rotation is transferred to the conducted differential gear wheel. The gear wheel, in turn, gives planetary knot, satellites and power shafts. Free rotation of satellites on the axes allows an internal wheel to rotate when passing turns more slowly than external.

At turning on of the reverse gear in gearing between its gear wheel and external teeths of the coupling of inclusion of 1-2 transfers the parasitic gear wheel enters. Such design provides necessary reduction in the rate of rotation and forces a secondary shaft to rotate in the opposite direction.

Primary and secondary shaft of a box are located in parallel each other, and also parallel to a bent shaft and power shafts. Gear wheels of both shaft is in continuous gearing. On neutral transfer of a gear wheel rotate on secondary to a shaft freely, without transferring rotation to the conducted gear wheel of the main transfer.

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 drive 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. As naves of the sliding couplings are equipped with the vents entered into gearing with vents of a secondary shaft, the gear wheel blocked on a nave begins to rotate together with shaft, providing the further drive with the corresponding transfer relation.
