Power shaft

Power shafts transfer torque from the engine, the 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 contracts, entering a shaft flute. After the shaft is completely established in a semi-axial gear wheel of differential, the lock ring is unclenched and fixes shlitsevy a tip from axial movement. External hinges of wire shaft fasten to naves of the forward wheels established on bearings. Fastening of a shaft to a nave is carried out by a nut with a fillet. For a nut otvorachivaniye exception, the fillet of a nut is bent in dredging of a power shaft. The side play between a nave and a power shaft is eliminated with an arrangement of shlits. Vents in a nave are located directly, and vents on a shaft are executed at a small angle. Various execution of shlits provides connection with a preliminary tightness, that is the motionless landing excluding all adjustments.

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

Tripoidny CV JOINTS can act and be served. Birfield CV JOINTS (ball) are not removed and are not served, on them replacement only of a protective cover is possible.
