Coupling device with a leg spring

摘要

The device (7) has a coupling part coaxially arranged to another coupling part. Each coupling part has engagement members e.g. jaws (9, 12) and tooth, for positive transmitting of torque between the coupling parts. A spring device tenses the engagement members in a circumferential direction. The spring device has a leg spring (13) with a ring part and legs (17, 18), where the ring part is arranged coaxial to the coupling parts and the legs extend outwards in a radial direction. A ring of the ring part is closed in an angular range greater than 320 degrees.
