Electromechanical braking mechanism for a motor vehicle

Abstract

An electromechanical brake apparatus for a motor vehicle comprises an adjustment apparatus and a brake component which is connected thereto and which can be adjusted by the adjustment apparatus along an axis and brought into braking engagement with a counter-brake component, wherein the adjustment apparatus has a first actuator and a second actuator which is coupled thereto in series, wherein the first actuator has a rotatably drivable first drive wheel by which a first output element and a first drive element which can be adjusted axially relative thereto can be rotatably driven relative to each other, and the second actuator has a rotatably drivable second drive wheel which is coaxial relative to the first drive wheel and by which a threaded spindle which has a spindle thread which engages in an inner thread of the first actuator can be rotatably driven. In order to enable a more compact and less complex construction, the threaded spindle and the second drive wheel have corresponding, mutually engaging positive-locking elements which are configured to produce a positive-locking connection which is effective with respect to rotation about the axis in a circumferential direction and which can be axially displaced relative to each other.
