Abstract

A freewheeling clutch assembly wherein pawl members are mounted for pivotal movement in one of a driven and driving member of the clutch assembly and wherein ratchets are formed in the other member. When the driven member overruns the driving member, pivotal movement of the pawls causes their disengagement with the ratchets and the clutch will freewheel. When the driving member commences again to overrun the driven member, resilient annular means interposed between the members will cause the pawl members to be pivoted back into their torque transmitting position.
