DEVICE FOR AN INTERNAL COMBUSTION ENGINE

摘要

A device for transmitting a torque from the crankshaft of an internal combustion engine to a drive shaft (6) of an ancillary unit comprises a pulley (1) of a belt drive, which is rotatably received on a housing (3) of the ancillary unit. Said pulley is linked with the drive shaft (6) of the ancillary unit so as to be movable. According to the invention, a device comprising a free engine clutch (8) limiting the torque that can be transmitted is provided in the power flux from the pulley (1) to the drive shaft (6) of the ancillary unit, thereby keeping away excess vibrational stress caused by the ancillary unit.
