Abstract:
1. An electromechanical apparatus for use in a controllable coupling assembly, the apparatus comprising: a housing part having a closed axial end including an end wall having an outer coupling face with a single pocket defining a load-bearing shoulder in communication with an inner face of the end wall; an electromagnetic source including at least one excitation coil at least partially surrounded by the housing part; an element received within the pocket in an uncoupling position and movable outwardly from the pocket to a coupling position characterized by abutting engagement of the element with the load-bearing shoulder; and a reciprocating armature arranged concentrically relative to the at least one excitation coil and being axially movable when the at least one excitation coil is supplied with current, the armature being connected to the element to move the element between the coupling and uncoupling positions wherein the element includes at least one projecting leg portion which provides an attachment location for a leading end of the armature and wherein each leg portion has an aperture and wherein the apparatus further comprises a pivot pin received within each aperture to allow rotational movement of the element in response to reciprocating movement of the armature and wherein the leading end of the armature is connected to the element via the pivot pin.
