ABSTRACT:
A cooling mechanism of an electromagnetic powder clutch comprises a drive member connected with an output shaft of an engine, a driven member connected with a main drive shaft through a pump drive shaft, a metal powder interposed in the gap between the drive member and the driven member for transmitting torque from the drive member to the driven member, a cooling fluid for cooling said electromagnetic clutch, a cooling passage provided in the driven member for letting flow the cooling fluid therein so as to cool the driven member, an oil supply passage provided in the driven member for supplying the cooling fluid to the cooling passage, an oil drain passage provided in the driven member for draining the cooling fluid from the cooling passage, a supply passage provided in a clearance between the main drive shaft and the pump drive shaft for supplying the cooling fluid to the oil supply passage, and a return passage provided in a center hole of the main drive shaft for returning the cooling fluid from the oil drain passage to a transmission.
