Parts of differential assembly

A differential assembly parts has got various parts. The different differential assembly parts are mentioned below:

•    Pinion Drive Gear: this part transfers the power to the ring gear from the drive shaft.

•    Differential case assembly: this part holds the Ring gear along with other components which drive the rear drive axle.

•    Ring Gear: this section transfers the power to the previous part that is Differential case assembly.

•    Rear drive axles: these are the steel shafts which transfer the torque from differential case assembly to drive wheels.

•    Axle housing: these are the metal body that encloses the rear axles and also supports the rear axle assembly.

•    Rear axle bearings: these are the ball bearings which fit between the axle housing and the axles.

•    Side gears: these gears help both the wheels to turn independently while turning.

How does the power flow in differential assembly parts?

•    Drive shaft rotates the Pinion gear.

•    The Pinion gear then becomes the bigger ring gear to produce a speed reduction.

•    The Ring gear which is attached to the differential case hence starts to rotate along with the ring gear.

•    The Differential case then turns the sun gears that are connected to the different axles.

•    The Axles shift the power towards the wheels.

Functions of differential assembly parts

•    It transfers the power from the drive shaft to all the wheels.

•    It provides a final reduction in gear.

•    It splits the amount of torque that is going to each of the wheels.

•    It allows the wheels to rotate and spin at various speeds during turns.

Why a differential assembly parts is required

Car wheels turn at different speeds while turning. The inside wheels always move lesser than the outside wheels. Hence the inner wheels travel a shorter distance. Also, the distance traveled by
