Abstract:
A torque limiting apparatus for transmitting power from a drive shaft connected to a drive source, to a differential gear system for driving a pair of wheel axes, the torque limiting apparatus comprising:a connecting shaft having an input side and an output side, said output side being adapted to be connected to the differential gear system, a hollow cylindrical casing having an interior and supported on the input side of the connecting shaft rotatably relative thereto, said hollow cylindrical casing having an input end and an output end, said input end of the casing being adapted to be connected to the drive shaft, said output end of the casing having an opening communicating with the interior of the casing, a seal member for interconnecting liquid-tightly the opening of the casing and an opening of a housing of the differential gear system, wherein the interior of the casing and an interior of the housing communicate with each other through the opening of the casing and the opening of the housing, and a connecting mechanism, provided between the casing and the connecting shaft, for transmitting only a partial power less than a predetermined torque value out of whole power input into the casing.
