Embodiment Construction
[0035] figure 1 A schematic plan view of a motor vehicle 10 with an electromagnetic service brake 12 according to the invention is shown. Here, the electromechanical service brake 12 includes a drive unit 14 , which may include, for example, an electric motor 16 that cooperates with a drive train 18 . In this case, the drive train 18 has a drive shaft 20 which is connected in a rotationally fixed manner with the first spur gear 22 . The first spur gear 22 meshes with the second spur gear 24 which in turn meshes with the third spur gear 26 . Here, the drive shaft 20 and the first spur gear 22 rotate about a first axis of rotation T1, wherein the second spur gear 24 and the third spur gear 26 rotate about a second axis of rotation T2 or about a third axis of rotation T3, which The three axes of rotation T3 extend substantially parallel to the first axis of rotation T1. The third spur gear 26 is connected in a rotationally fixed manner to the main shaft 28 which meshes with th...

The invention relates to a locking device for an electromechanical service brake (12) of a motor vehicle (10), wherein the electromechanical service brake has a ratchet (46) mounted rotatably about an axis of rotation (T), said The ratchet is non-rotatably connectable or connected to a drive shaft (20) rotatable about the same axis of rotation of the drive train (18) of the electromechanical service brake, and the locking device (48) comprises a locking plunger ( 50), the locking plunger is axially movable along the displacement axis (A) between a first position and a second position in which the locking plunger releases the ratchet (46 ), in said second position, said locking plunger is engaged in said ratchet (46) for locking; a movement device for moving said locking plunger along said displacement axis (A) (52); and position determining means (58) for determining the position of said locking plunger.
Description
technical field [0001] The invention relates to a locking device for an electromechanical service brake of a motor vehicle. Furthermore, the invention relates to an electromechanical service brake for a motor vehicle having such a locking device. Furthermore, the invention relates to a motor vehicle having such an electromechanical service brake. Background technique [0002] Electromechanical service brakes, also known as "Brake by Wire", are increasingly being used to replace hydraulically operated braking systems. The reason for this is that electromechanical service brakes enable the individual wheels of the motor vehicle concerned to be braked individually in a simple manner, which can only be achieved with high outlay using hydraulically actuated braking systems. Typically, the equipment outlay for electromechanical service brakes is significantly lower than for hydraulically operated service brakes. The basic structure is limited to the control unit, the electric m...
