Differentialgetriebe.

摘要

A differential gear mechanism has a clutch (8) formed and acting between a pair of worm gears (2,3) each of which are connected to different axle shafts (13,14). The clutch (8) releasably inter-connects the worm gears (2,3) to lock the differential. As a result, even if a wheel connected to one of the axle shafts (13,14) falls into a completely skidding state, drive torque is still transmitted to the other axle shaft (14,13). When the connected state of worm gears (2,3) is released, an ordinary differential operation is performed.
