Towson Central Differential
The core of the Torsen differential is the worm gear and the worm drive system, as shown in Figure 2. It is their mutual meshing interlock and the configuration in which the torque is transmitted unidirectionally from the worm gear to the worm gear to realize the differential lock function, which limits the slip. When driving in a corner, the front and rear differentials function as a conventional differential. The worm gear does not affect the output speed of the half shaft. If the car turns to the left, the right wheel is faster than the differential. The worm wheel with low speed on the left side and different left and right speeds can closely match the synchromesh gear. At this point the worm gear is not locked because the torque is from the worm gear to the worm gear. When one side of the wheel is slipping, the worm gear assembly functions to automatically adjust the power distribution very quickly through the Tosson differential or the hydraulic multi-disc clutch.
