Manual box of gear shifting
Assembly of the gear shifting box (GSB) is placed in a cast aluminum case, pribolchenny to the left end face of the engine. Mechanisms actually of the transmission, and also differential of the main transfer are a part of assembly.
Rotation is transmitted from a bent shaft of the engine through assembly of coupling on the main shaft RKPP equipped with the pin extended and equipped with vents which is passed throughout a nave of a frictional clutch plate. The main shaft of a box rotates in the non-demountable, placed in the tight case ball-bearings. From a main shaft rotation is transferred to a secondary shaft of a box which right end is passed throughout the roller bearing, and left - to the ball-bearing of tight execution. The output end of a secondary shaft of a box is entered into gearing with the koronchaty conducted gear wheel of the main transfer which is rigidly connected to a box of differential and the planetary assembly placed in it. From side gear wheels of differential rotation is transferred to power shafts and further - to the leading forward wheels of the car. Gear wheels of satellites freely rotate on the axis that provides a possibility of rotation of driving wheels of the car with various speed, completely eliminating with that probability of pro-slipping of an internal wheel during commission of maneuvers.
Primary and secondary shaft of the transmission are located in parallel each other, and also parallel to a bent shaft and power shafts of the leading bridge. In view of feature of a configuration of a gear wheel of both shaft constantly are in gearing with each other. In the neutral provision of a gear wheel rotate on secondary to a shaft freely, without transferring torque to the conducted gear wheel of the main transfer.
Gear shifting is carried out through the salon of a control lever established on a floor RKPP and the drive of the mechanism of the choice of transfers. The drive of the mechanism of the choice of transfers 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 with the naves. 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. For a guarantee of speed and quality of gear shifting synchronization of all forward transfers is provided in a box.
