Principle and Type Analysis of Limited Slip Differential——Type

1. Torsen differential: The so-called Torsen differential is to use worm gear to achieve self-locking, which can work continuously like ordinary differentials, and has no delayed response, and does not interfere with the total torque The adjustment of the output, at this time, there is no loss of torque. Compared with the traction control and body stability control systems, it has a greater advantage in performance and is heavier in weight.

2. Helical gear differential: In fact, the principle is no different from the former, but the helical gear is parallel to the half shaft, and the helical gears are meshed with each other, which means that there will be a certain amount of wear and tear. But it will be slightly lighter in weight.

3. Mechanical differential: It mainly uses two sets of left and right pressure plate groups and clutch plates. The limited slip percentage function can be achieved by the arrangement and combination of clutch plates and pressure plates, and the response speed is very fast, but the difference between the differential oil The fluidity is relatively poor and the heat dissipation performance is not very good, so the durability is not very good.

4. Eaton differential: In fact, this differential is also a mechanical differential, but it is slightly simpler in structure than a mechanical differential. A flyweight is set in the differential housing. When the speed difference reaches When a certain value is reached, the flyweight will be locked, and the wheels on both sides will be connected linearly, so as to achieve the purpose of getting out of trouble.
