Non-Aligning Bearings 5-101X Automotive Universal Joint with 4 Plain Round Bearing

Non-Aligning Bearings 5-101X with 4 Plain Round Bearing Universal Joint for Cars , 23.8 x 61.3mm

Description: 

Universal joints are capable of transmitting torque and rotational motion from one shaft to another when their axes are inclined to each other by some angle, which may constantly vary under working conditions. Universal joints are incorporated in the of vehicle’s transmission system to perform three basic applications :

(a) Propeller shaft end joints between longitudinally front mounted gearbox and rear final drive axle.

(b) Rear axle drive shaft end joints between the sprung final drive and the unsprung rear wheel stub axle.

(c) Front axle drive shaft end joints between the sprung front mounted final drive and the unsprung front wheel steered stub axle.

Universal joints have movement only in the vertical plane when they are used for lon­gitudinally mounted propeller shafts and transverse rear mounted drive shafts. When these joints have been used for front outer drive shaft they have to move in both the vertical and horizontal plane to accommodate both vertical suspension deflection and the swivel pin angular movement to steer the front road wheels. The compounding of angular working movement of the outer drive shaft steering joint in two planes imposes large and varying working angles even when the torque is being transmitted to the stub axle. Due to the severe working conditions, special universal joints known as constant velocity joints are employed. These joints have been designed to absorb torque and speed fluctuations and to operate reliably with very little noise and wear having long life.
