Freewheel coupling
Abstract:
A form-fitting freewheel coupling, which has a first and second clamping track with latching structures, a gap space between the clamping tracks, and a clamping ring arranged in the gap space. The clamping ring has clamping tongues facing toward the first clamping track and clamping tongues facing toward the second clamping track. A drag ring is arranged in the gap space. The drag ring is pivotable to a limited extent, relative to the clamping ring and is spring-loaded against one of the clamping tracks and interacts with the clamping ring in such a way that, in the event of a rotation of the first clamping track relative to the second clamping track in the freewheel direction, the clamping ring is lifted fully from one of the clamping tracks, while the clamping tongues, which face away from the clamping track, protrude into the latching structures of the opposite clamping track.
