What Is Limited Slip Differential ? How Does It Work

Are you aware of the working of the limited slip differential? If not, then, don’t worry because this article will give you a complete knowledge about the working of It. First let us know first why we need it.

Before the usage of this limited slip differential, the standard differential was discovered. But in the case of the standard slip differential, there were many problems. One of the main reasons why we use the limited slip differential over standard differential is as below:

In case of the standard slip differential, both the axles of the wheels move with a different speed. Consider a vehicle which is running on the road, its one wheel is on the slippery surface while another wheel on the surface with a good contraction or a surface which is dry. As the axles rotate with different angular velocities, power transferred to the wheel on the slippery road will be high while the power transmitted to the wheel on the dry surface will less. So, the wheel on the slippery surface will rotate with higher speed than the wheel on a surface with a good contraction. Due to this big relative difference in the rotations of the two wheels the car will not move at all. So, to solve this problem the limited slip differential is used.

For the clarification of the above paragraph, just refer to the following image:
Limited slip differentialA limited slip differential is a type of differential that limits the amount of rotational difference between the two output shafts.

In 1935, such type of differential was designed by the company, ZF Friedrichshafen. Limited Slip Differential is popularly known as LSD.Basically, there are four types of the LSD which are used in the cars that we see on roads. Following are the four types of the LSD that you must know:

  • Electronically Controlled LSD
  • LSD of fixed value
  • LSD which are operated by the torque
  • Speed Sensitive LSD
