摘要

A clutch mechanism designed to include a free-wheeling unit which is disengageable in the driving direction consisting of a clutch hub and a clutch sleeve which cooperate with locking catches, with the clutch sleeve being embraced by a control ring. Control pins are radially guided in the clutch sleeve and, by turning the control ring relative to the clutch sleeve, inclined faces formed on the control ring act on the control pins to actuate the locking catches to permit disengagement of the driving connection.
