A brake actuator unit for an electromechanical brake has a spindle, a spindle bearing, which receives the spindle, and a cup-shaped brake piston bearing section, which has a circumferential wall and a base, against which the spindle bearing is supported axially during the actuation of the brake. The brake actuator unit furthermore has a strain sensor having a sensor element, which is arranged on an outer circumference of an axial section of the circumferential wall and is configured to detect a strain of the axial section in a circumferential direction. Moreover, a strain sensor for a brake actuator unit of this kind is provided. Furthermore, an electromechanical brake having a brake actuator unit of this kind and/or having a strain sensor of this kind is provided.
A brake actuator unit for an electromechanical brake, comprising a spindle, a brake piston coupled to the spindle, a spindle bearing, which receives the spindle and absorbs axial reaction forces of the spindle during the actuation of the brake, and a cup-shaped brake piston bearing section, which has a circumferential wall and a base, against which the spindle bearing is supported axially during the actuation of the brake, wherein the brake actuator unit has a strain sensor having at least one sensor element, which is arranged on an outer circumference of an axial section of the circumferential wall and is configured to detect a strain of the axial section in a circumferential direction.
