Embodiment Construction
[0037] figure 1 with figure 2 A fastening device 10 according to the invention is schematically shown. This fixture is provided with two separate drives, the transmission lock drive 22 and the differential lock drive 42 . The transmission locking drive 22 and the differential locking drive 42 are each embodied as either electromechanical or hydraulic actuators. A transmission locking device 20 and a differential locking device 40 are thus formed. With regard to the mode of operation, the two shafts (ie the transmission locking shaft 24 and the differential locking shaft 44 ) are now drivingly connected to one another via corresponding coupling sections 25 and 45 . Redundant operation is achieved by the coupling of the transmission lock drive 22 and the differential lock drive 42 .
[0038] At least one of the two drives 22 and 42 is now activated for the imposition of the stationary situation, ie the locking of the driven wheels. During normal driving operation, the tran...
