Abstract

A switchable coupling with a coupling system between a driving element and an output element is provided. The switchable coupling includes an actuator, an elastic actuating element and a switching element movable between starting, central and end positions. In the central position the switchable coupling has a different state (open or closed) than in the starting position. The switchable coupling further includes a bolt constrained between first and second bolt stops. Axial movement of the switching element causes operative surfaces connected to the switching element or the bolt to engage with elements on other of the switching element and the bolt, such that the bolt rotates relative to the switching element. The bolt alternately moves relative to the switching element into a first relative position blocking switching element movement in the central position, and into a second relative position permitting movement of the switching element toward the starting position.
