The general informationGear change box - appearance
Assemblage of a box gear changes (check point) is placed in cast aluminium картер, приболченный to the left end face of the engine. The assemblage structure includes mechanisms actually transmissions, and also differential of the main transfer.
Rotation is transferred from a cranked shaft of the engine through coupling assemblage to the primary shaft РКПП equipped extended and equipped шлицами with a pin which is passed in a nave of a frictional disk of coupling. The primary shaft of a box rotates in not folding ball-bearings placed in the tight case. From a primary shaft rotation is transferred to a secondary shaft of the box which right end is passed in the roller bearing, and left - in the tight ball-bearing. The target end of a secondary shaft of a box is entered into gearing with корончатой a conducted gear wheel of the main transfer rigidly connected to a box of differential in which there is a planetary assemblage. From lateral gear wheels of differential rotation is transferred further to power shafts and further - on leading forward wheels of the car. Gear wheels of satellites are freely planted on the axis that provides possibility of rotation of driving wheels of the car with various speed, completely eliminating thereby probability of proslipping of an internal wheel during fulfilment of maneuvers.
Primary and secondary shaft of a transmission are located in parallel each other, and also to in parallel cranked 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 a conducted gear wheel of the main transfer.
The gear change is carried out by means of the salon of control lever РКПП established on a floor and means drive the mechanism of a choice of transfers. The drive of the mechanism of a choice of transfers consists of a set of plugs of switching with which help sliding муфты synchronizers move along a shaft, carrying out blocking of gear wheels of corresponding transfers with the naves. As naves sliding муфт are equipped шлицами, entered into gearing with reciprocal шлицами the secondary shaft, the gear wheel blocked on a nave starts to rotate together with shaft, providing the further drive with the corresponding transfer relation. For a guarantee of speed and quality of a gear change in a box synchronisation of all forward transfers is provided. Synchronisation is provided at the expense of application of blocking rings with подпружиненными sliding keys and naves of synchronizers with gear wheels. Cones of synchronizers provide surfaces of interface of blocking rings with gear wheels. More in detail a principle a design and functioning РКПП are described in Section a system Design, the description of separate knots and mechanisms.
