Abstract
A limited slip differential includes a driving plate, backing plates, differential gear assemblies, and a transmission assembly engaged together inside a sealed casing where fluid is pumped. The driving plate has pairs of communicated openings for interlocking two gears of each gear assembly, which extend by opposite directions from the driving plate for separately engaging with the transmission assembly. While synchronously rotating the plates, the gear assemblies are alternatively soaked into the fluid and each permits the fluid passing among the gears for adjusting the rotational speed. In the event that the rotational speed difference of axle shafts of the vehicle exceeds a threshold value, the LSD applies at least one gear assembly to generate a back pressure and efficiently block the fluid passing through the gears for limiting mutual rotational speed difference, hence achieving a limited-slip effect.
