General information Gear shifting box - appearanceAssembly 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 tight ball-bearing. 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 differential box in which there is a planetary assembly. From side gear wheels of differential rotation is transferred further to power shafts and further - to the leading forward wheels of the car. Gear wheels of satellites are freely put 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. 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 through the salon of a control lever of RKPP established on a floor and by means of the driving 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 reciprocal 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. Synchronization is provided due to application of the blocking rings with the sprung sliding keys and naves of synchronizers with gear wheels. Cones of synchronizers provide the surfaces of interface of the blocking rings to gear wheels. More detailed the principle the design and functioning of RKPP are described in the Section System Design, the description of separate knots and mechanisms. |
