Power shaft

Power shafts transfer a torque from the engine, a transmission and differential to forward wheels. In a transmission case power shafts fasten shlitsevy connections with semi-axial gear wheels of differential. Fixing of a shlitsevy tip of the internal hinge of a power shaft in a semi-axial gear wheel is made by a spring lock ring.

At installation the lock ring is compressed, entering into a shaft flute. After the shaft is completely established in a semi-axial gear wheel of differential a lock ring is unclenched and fixes shlitsevy a tip from axial moving. External hinges of wire shaft fasten to naves of the forward wheels established on bearings. Shaft fastening to a nave is carried out by a nut with a fillet.

For an exception of an otvorachivaniye of a nut the fillet of a nut is bent in dredging of a power shaft. Люфт between a nave and a power shaft it is eliminated with an arrangement шлицов. Shlitsa in a nave are located directly, and shlitsa on a shaft are executed at a small angle. Various execution шлицов provides connection with a preliminary tightness, that is motionless landing of adjustment excluding everything.

Hinges of equal angular speeds (CV JOINTS) are established from two parties of a power shaft. All external CV JOINTS of the Birfield type, and internal – tripoidny type. CV JOINTS of tripoidny type are used for prevention of transfer of vibrations of the engine through power shafts on a car body. CV JOINTS are necessary for transfer of a torque and compensation of movement of a forward suspension bracket. Also, CV JOINTS allow to change length of a power shaft and to transfer a torque under constantly changing corners. For ensuring flexibility in CV JOINTS of the Birfield type use the balls located in the case of the hinge. In Tripoid type hinges (tripoidny type) three rollers, established on the basis with three axes are used.

CV JOINTS can act in film and be served by Tripoidnye. Birfield type CV JOINTS (ball) do not act in film and are not served, on them replacement of only a protective cover is possible.
