Abstract
In order to increase an automatic connecting speed at a torque limiting coupling, a torque limiting coupling (1) has a coupling hub (5). Driving elements (8) are adjustably held in the apertures and extend parallel to the longitudinal axis. A coupling sleeve has first recesses (23) corresponding to the apertures. A switching disc (14) is rotatably arranged between a connected position and a freewheeling position, relative to the coupling hub. The switching disc (14) can be transferred by a rolling movement of the driving elements (8) from the connected position into the freewheeling position. The switching disc (14) has second recesses (34) that engage the driving elements (8) in the freewheeling position. A first and second spring mechanism load the switching disc (14) in the circumferential and axial direction. Circumferential play (28) is formed between the driving elements (8) and the first recesses (23) in the connected position.
