Abstract
Specified is a brake actuator (), in particular for an electromechanical vehicle brake (), having an electric motor () for activating the vehicle brake (), and a blocking module () for selectively rotationally blocking an output shaft () of the electric motor () so as to configure a parking brake function. The blocking module () comprises a blocking lever () which is mounted so as to be pivotable between a locking position and a releasing position, and a blocking actuator () for pivoting the blocking lever (), wherein configured on the blocking lever () is a blocking tooth () which in the locking position of the blocking lever () engages with a gear wheel coupled to the output shaft () of the electric motor (). The blocking tooth () on one tooth flank () has a blocking geometry (), and on an opposite tooth flank () has a lifting geometry (), said geometries () being configured in such a manner that in a rotation of the electric motor () in a first direction that boosts a braking force, the blocking lever () by the rotation of the electric motor () is lifted counter to a spring force so as to disengage from the gear wheel, and a rotation of the electric motor () in an opposite direction that releases the braking force is blocked. A vehicle brake () is furthermore specified.
