Title: ACTUATING UNIT FOR LOCKING AND RELEASING A ROTATIONAL MOVEMENT
Abstract:
The invention relates to an actuating unit for locking and releasing a rotational movement about a shift shaft (2), between a stator (3) and a rotor (14), wherein the rotor (14) has an internal geared ring (20) which runs at least in sections along a circular arc, wherein the shift shaft (2) is arranged at the centre point of the circular arc, wherein a first toothed slide (24) and a second toothed slide (24) are arranged on the stator (3) in such a way that they can be displaced in each case parallel to a first central of the internal geared ring (20) of the rotor (14) in a straight line along a first movement direction or along a second movement direction between a locked position and a rotating position, wherein, in the locked position, a first external toothing system (53) which lies opposite the internal geared ring (20) of the rotor (14) on the first toothed slide (24) or a second external toothing system (53) on the second toothed slide (24) engages in each case into the internal geared ring (20), wherein, in the rotating position, the first external toothing system (53) and the second external toothed system (53) are out of engagement with the internal geared ring (20), wherein the movement between the locked position and the rotating position takes place by means of an eccentric (27) which is connected to the shift shaft (2), wherein the first movement direction and the second movement direction are at the same spacing from the first central of the internal geared ring (20) and are arranged on opposite sides of said central, wherein the eccentric (27) has a number of actuating sections which is equal to the number of toothed slides (24, 25), and in each case one actuating section is assigned to a toothed slide (24, 25), wherein a spiral spring (31) is arranged between the shift shaft (2) and the stator (3).
