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 cooperating 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 to a first spur gear 22 . The first spur gear 22 meshes with a second spur gear 24 , which in turn meshes with a third spur gear 26 . Here, the drive shaft 20 and the first spur gear 22 rotate around a first axis of rotation T1, wherein the second spur gear 24 and the third spur gear 26 rotate around a second axis of rotation T2 or around a third axis of rotation T3, which The third axis of rotation T3 runs approximately parallel to the first axis of rotation T1 . The third spur gear 26 is connected in a rotationally fixed manner to a main shaft 28 which meshes with a main shaft s...

A blocking device for an electromechanical service brake of a motor vehicle, wherein the electromechanical service brake comprises a ratchet gear, supported rotatably about a rotational axis, which ratchet gear is connected or is connectable torque-proof with a drive shaft, rotatable about the same rotational axis of a power train of the electromechanical service brake, and the blocking device comprises a blocking tappet which is axially movable along a displacement axis between a first position, in which the blocking tappet releases the ratchet gear, and a second position, in which the blocking tappet for the purpose of blocking engages into the ratchet gear, a moving system for moving the blocking tappet along the displacement axis, and a position determination system for determining theposition of the blocking tappet and an electromechanical service brake for a motor vehicle with such a blocking device and to a motor vehicle with such an electromechanical service brake.
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 instead of hydraulically operated braking systems. The reason for this is that electromechanical service brakes are able to brake the individual wheels of the relevant motor vehicle in a simple manner, which can only be achieved at great expense using a hydraulically actuated brake system. Generally, the equipment outlay for electromechanical service brakes is significantly lower compared to hydraulically actuated service brakes. The basic structure is limited to the control unit, electric motor and, dependin...
