Abstract
The present disclosure relates to an electromechanical actuation unit for a motor vehicle brake comprising: at least one electromechanical actuation device for actuating at least one brake shoe of the motor vehicle brake. The electromechanical actuation device has at least drive element and at least one drive spindle, wherein the at least one drive element drives the at least one drive spindle. The electromechanical actuation device has at least one elastic element, the at least one elastic element being elastically deformable for a parking brake function.

An electromechanical actuation unit for electromechanically actuatable motor vehicle brake, comprising:
- at least one electromechanical actuation device for actuating at least one brake shoe of the motor vehicle brake,
- wherein the electromechanical actuation device has at least one drive element and at least one drive spindle, wherein the at least one drive element drives the at least one drive spindle,
- wherein the electromechanical actuation device has at least one elastic element, the at least one elastic element being elastically deformable for a parking brake function such that the elastic deformation of the at least one elastic element mechanically locks the at least one actuation device in a parking brake position and
- wherein a relative displacement between the at least one drive element and the at least one drive spindle is possible with elastic deformation of the at least one elastic element,
- wherein the at least one electromechanical actuation device has at least one stop element which has at least one externally threaded portion, and
- wherein the at least one stop element comprises at least one recess configured to receive a projection extending from the at least one drive element, such that the projection and recess cooperate to limit movement and enhance mechanical locking.
An electromechanical actuation unit for electromechanically actuatable motor vehicle brake, comprising:
- at least one electromechanical actuation device for actuating at least one brake shoe of the motor vehicle brake,
- wherein the electromechanical actuation device has at least one drive element, at least one drive spindle, and at least one coupling element, wherein the at least one drive element drives the at least one drive spindle,
- wherein the electromechanical actuation device has at least one elastic element, the at least one elastic element being elastically deformable for a parking brake function, and
- wherein the at least one coupling element interacts with the elastic element for coupling the at least one drive spindle to the at least one drive element;
- wherein the at least one drive spindle has at least one depression for the at least one coupling element,
- wherein the at least one drive element has at least one opening for receiving the at least one coupling element and
- wherein the at least one elastic element presses the at least one coupling element into the at least one depression.
