Motor vehicle brake, in particular a motor vehicle brake that can be actuated in a combined hydraulic and electromechanical manner, comprising a multi-stage spindle

A motor vehicle brake adapted to be actuated in a combined hydraulic and electromechanical manner, having an actuator assembly comprising:

• a housing,
• an actuating element that is displaceable relative to the housing along a longitudinal axis for a hydraulic or electromechanical displacement of a brake lining,
• a motor drive, and
• a displacement mechanism, situated between the motor drive and the actuating element, for displacing the actuating element, wherein the displacement mechanism has a multi-stage spindle-nut arrangement comprising a first spindle-nut pair having a first thread pitch and a second spindle-nut pair having a second thread pitch, wherein the first thread pitch is larger than the second thread pitch, wherein, during an electromechanical actuation of the motor vehicle brake, the first spindle-nut pair is active in a first actuating phase and the second spindle-nut pair is active in a second actuating phase, and
• wherein the second spindle-nut pair has a second spindle and a second nut, the second nut being coupleable to the actuating element in a rotatably fixed manner, and the second spindle being rotatably drivable by the motor drive,
• wherein the second nut of the second spindle-nut pair has two parts, a first nut section being coupled in a rotatably fixed manner to a second nut section via a connecting pin, but being displaceable relative to the second nut section in an axial direction, the first nut section and the second nut section being stretched apart from one another in the axial direction via a compression spring mechanism.
