Parts of differential assembly coming up with a useful functionality

A differential assembly 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?

• 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

• 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 part 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
