Switchable freewheel device for crankshaft pulley for transmitting torque between crankshaft and belt drive, is provided with inner ring rotated relative to outer ring, where freewheel cage is arranged between clamping elements

摘要

The switchable freewheel device (20) is provided with an inner ring (21) rotated relative to an outer ring (16), where a freewheel cage (28) is arranged between clamping elements (26). An electric motor (30) is coaxially arranged to the inner ring and the outer ring for switching the freewheel device. The electric motor has a rotor rotatably mounted relative to the outer ring and a fixed stator. The stator of the electric motor is mounted on a pin. An independent claim is included for a crankshaft pulley for transmitting a torque between a crankshaft and a belt drive.
