Abstract

An axially actuatable positive engagement clutch which includes an input shaft with an input toothing and an output shaft with an output toothing. An axially displaceable connection element can occupy a meshing position which is located in an actuation path (s) between the open position and the closed position and in which the driving toothing engages with the input toothing or the output toothing for the first time during the transition from the open position into the closed position. An actuation device is configured to displace the connection element from the closed position to the open position, and an elastic return element which applies a restoring force to the connection element in direction of the closed position. The return element has a force/deflection characteristic with a local force maximum (F1) which coincides in the actuation path (s) at least approximately with the meshing position of the connection element.
