摘要： A switchable coupling (1) with a coupling system (4) between a driving element (2) and an output element (3), wherein the switchable coupling (1) has a preferably electromagnetic actuator (5) and a switching element (6) in the operative vicinity of the actuator (5), and at least one elastic actuating element (10) arranged between the output element (3) and the switching element (6). The switching element (6) is movable in an infinitely variable manner between a starting position (7) via a central position (8) as far as an end position (9), wherein, in the central position (8) of the switching element (6), the switchable coupling (1) has a different state (open or closed) than in the starting position (7). The switchable coupling (1) also has a bolt (11) which is fixedly positioned in the axial direction within the switchable coupling (1) by means of a first bolt stop (12) and a second bolt stop (13). By means of the axial movement of the switching element (6) to and fro upon activation and deactivation of the actuator (5), operative surfaces (24 and 28) of a rotational system (23) connected to the switching element (6) or the bolt (11) come into engagement with moulded elements (26, 27, 30, 31) on the switching element (6) and on the bolt (11) in such a manner that the bolt (11) is rotated in a stepwise manner in relation to the switching element (6). As a result, the bolt alternately moves relative to the switching element into a first relative position (16), in which the bolt blocks a movement of the switching element (6) in the central position (8), and into a second relative position (18), in which said bolt permits a movement of the switching element (6) as far as the starting position.

摘要： The invention relates to a switchable coupling, in particular for passenger vehicle auxiliary assemblies, with an actuating system, which is actuated electrically, mechanically, pneumatically or hydraulically, between a driving element, which is designed, for example, in the form of a pulley, and an output element, wherein the actuating system contains a switching element which, upon actuation of the actuating system, is movable between a switching start position and a switching end position counter to the force of one or more resetting elements, for example springs, wherein, in the switching end position, the switching element produces an operative connection between the driving element and the output element such that, when the driving element rotates, the output element and also an auxiliary coupling connected to the output element are caused to rotate, wherein, after deactuation of the actuating system, the locking bodies located on the auxiliary coupling produce a frictional and/or form-fitting operative connection between the driving element and the output element such that, even after deactuation of the actuating system, a torque can be conducted from the driving element to the output element, wherein the operative connection is interrupted only when the rotational speed of the driving element falls below a limit value. The advantage of this solution consists in the coupling not requiring a permanent supply of power in the switching states "coupling = closed" and "coupling = open".
