ABSTRACT:
A rotation transmission device mounted on a 4WD car can stop the front drive train during 2WD mode, and also permits smooth changeover from 2WD to 4WD even while the vehicle is moving. The rotation transmission device is mounted in a transfer which transmits the output of the engine transmission to the rear propeller shaft through an input shaft and to the front propeller shaft through a silent chain. The rotation transmission device includes a two-way clutch through which the rotation of the input shaft is selectively transmitted to a chain sprocket, an electromagnetic clutch for selectively locking and unlocking the two-way clutch, and a multiple disk clutch provided between the two-way clutch and the electromagnetic clutch to function as a synchronizer that permits smooth mode change from 2WD to 4WD even while the vehicle is moving.
