Power shafts

The car is set in motion due to torque transmission from axial differentials to driving wheels of forward and back bridges of the car by means of four power shafts (two lobbies and two back). Boots of internal hinges are made of rubber, and external - of thermoplastic (thermoplastic is steadier against external influences). Each shaft consists of three main parts: internal hinge, directly shaft and external hinge of equal angular speeds (HEAS). The internal hinge of a shaft is fixed in assembly of the corresponding differential by means of a lock ring. External hinges (CV JOINTS) terminate in shlitsevy pins which enter shlitsevy naves of driving wheels. Fixing of pins in naves is carried out by means of stupichny nuts.
