Blocking device for an electromechanical service brake of a motor vehicle electromechanical service brake with such a blocking device and motor vehicle with such an electromechanical service brake

摘要

The present invention relates to a shut-off device for an electromechanical drive brake (12) of a motor vehicle (10), comprising a locking wheel (46) rotatably supported around an axis of rotation (T) and the lock wheel is rotatably connectable or connected to the drive shaft 20 of the driveline 18 of the electromechanical drive brake 12 rotatable around the same rotation axis T, and the blocking device 48 is lockable. a locking plunger (50), a movement device (52) for movement of the locking plunger (50) along an axis of movement (A) and a positioning device (58) for positioning the locking plunger (50); is the axis of movement A in the axial direction between a first position in which the locking plunger 50 releases the locking wheel 46 and a second position in which the locking plunger 50 engages into the locking wheel 46 for blocking. can move along. The invention also relates to an electromechanical drive brake (12) for a motor vehicle (10) comprising such a shut-off device (48). The invention also relates to a motor vehicle (10) comprising such an electromechanical drive brake (12).
