The invention relates to a device (01) for actuating a clutch-controlled transfer case having a two-stage intermediate gearing and a clutch-controlled transfer case that has a two-stage intermediate gearing and that is equipped with such a device. The device (01) comprises: a rotatably driven selector shaft (02), a drive for rotating the selector shaft (02), a clutch cam disk (03), which can be rotated about a clutch cam disk axis (30) by means of the selector shaft (02), and at least one scissor lever (5, 51, 52), wherein: an end (06) of at least one scissor lever (05, 51, 52) is guided in a gate (07) provided on the clutch cam disk (03), the gate (07) has a curved path (71, 72) for each scissor lever (05, 51, 52), in which curved path the end (06) of the scissor lever (05, 51, 52) associated with the curved path (71, 72) is guided, the curved path (71, 72) winds around the clutch cam disk axis (30) by at least 360°, the curved path (71, 72) has at least one spiral segment (70) having a continuously increasing or decreasing distance from the clutch cam disk axis (30), along which segment (70) an end (06) of a scissor lever (05, 51, 52) guided therein experiences a continuously increasing or decreasing change in the deflection of said end of said scissor lever with respect to the clutch cam disk axis (30) during a rotation of the clutch cam disk (03) with increasing angle of rotation, and the clutch cam disk (03) is arranged in such a way that the clutch cam disk can be rotated in relation to the selector shaft (02) between two stops (31, 32) by an angle-of-rotation range (2) such that, by means of rotation of the selector shaft (02) within the angle-of-rotation range (2) lying between said stops (31, 32), shifting back and forth between the shifting stages of the intermediate gearing occurs, and, by means of rotation of the selector shaft (02) beyond the angle-of-rotation range (2), the end of the at least one scissor lever (05, 51, 52) experiences a deflection in order to actuate the clutch while a selected shifting stage is maintained. |
