Embodiment Construction

[0036] In the following, an exemplary embodiment of a subassembly of an electromechanical brake actuator for an electrically operated parking brake is described, it being understood that the presented subassembly is also applicable to an electromechanically operated service brake.

[0037] Corresponding elements in the figures have the same reference numerals. Terms such as "top" and "lower side" or "at the top" and "on the lower side" or "horizontal" or "vertical" refer to the orientation of components as shown in the figures. It should be understood that the subassembly is normally mounted horizontally in the electric parking brake (in other words, rotated by 90° compared to the representation in the figures).

[0038] figure 1 A cross-sectional view of the electromechanical brake actuator 10 according to the first exemplary embodiment is shown. The electromechanical brake actuator 10 includes a subassembly 12 of a drive 16 having an electric motor 17 . Furthermore, the s...

Abstract

The invention relates to a subassembly (12) for an electromechanical brake actuator (10). Said subassembly (12) comprises a drive device (16) for generating a torque and a gear mechanism (18) for transmitting the torque, said gear mechanism (18) comprising, one behind the other, a first, a second and a third gear speed (22, 24, 26). The second gear speed (24) is configured as a planetary gear set. The invention further relates to an electromechanical brake actuator (10) comprising said subassembly (12).

Description

technical field [0001] The present disclosure relates to the field of motor vehicle brakes. More specifically, the present disclosure relates to subassemblies of brake actuators, for example, for electromechanically operated parking brakes or electromechanically operated service brakes. Background technique [0002] Electrically operated parking brakes (EPB) are increasingly frequently replacing conventional parking brakes, which convert the force applied by the driver via pulleys into clamping forces at the vehicle's wheel brakes. The advantage of electric parking brakes is that they can be controlled with modern on-board electronics. In this way, new application possibilities of the parking brake are opened, such as, for example, enabling assisted starting on slopes (slope hold function). [0003] Electrically operated parking brakes typically include an electromechanical brake actuator that applies a clamping force to the wheel brakes via a mechanically displaceable bra...
