A device for mechanically disengaging an automatically engaged clutch device 2, 3 having a hydraulic or electrical disengaging mechanism 4. The hydraulic disengaging mechanism 4 has a disengaging lever 6 that can be moved via a hydraulic disengaging cylinder 5 and has a central disengaging bearing 7. The central disengaging bearing 7 relieves a contact disk 8, and releases a clutch disk 9. An electrical disengaging mechanism works with clutch lamellae 18, 19, which are released when a solenoid element is excited, and mechanically block a clutch disk 9 with the solenoid element de-energized. An electrically operated hydraulic pump 10 with electrically actuated coupling lamellae can automatically disengage an automatically engaged clutch device 2, 3 via the disengaging mechanism 4 during automatic switching processes. A hydraulic supply line 13 secured by a check valve 12 is coupled to the electrical hydraulic pump 10 or to the solenoid element, and connected with a manual hydraulic pump 14 to release a blocked clutch disk 9. The manual pump may be a hand pump or a foot PUMP. |
