Differential shell blanks on modern cars are usually divided into two categories: geared differentials and slip differentials according to their working characteristics.

Slip differential. In order to improve the passing ability of the car on bad roads, some off-road vehicles and high-end cars are equipped with anti-slip Differential shell blank. The characteristic of a slip differential is that when one side of the drive wheel slips on a bad road, most or all of the torque can be transferred to the drive wheel on a good road. In order to make full use of the adhesion of this driving wheel to generate enough driving force, the car can start or continue to run smoothly.
To achieve the above requirements, the easiest way is to set a differential lock on the symmetrical bevel gear Differential shell blank, making it a positive locking differential. When one side of the drive wheel is slipping, the differential lock can be used to lock the differential and not act as a differential.
Through the above introduction and analysis of the Classification of Differential shell blank, hope it helps you.
