ACTUATOR ASSEMBLY FOR A VEHICLE BRAKE AND METHOD FOR ACTIVATING AN ACTUATOR ASSEMBLY FOR A VEHICLE BRAKE

An actuator assembly for a vehicle brake is described. It comprises a carrier assembly () on which an activating carriage () for a brake lining is guided linearly. Moreover, an electric motor fastened to the carrier assembly () is provided which is coupled drivingly to the activating carriage via a gear unit and a spindle drive such that the activating carriage can be displaced selectively between a retracted position and an extended position. In addition, the actuator assembly comprises a locking assembly () for selectively immobilizing in rotation an output shaft () of the electric motor. The locking assembly () here comprises a locking lever () which at a first end () is mounted rotatably on the carrier assembly () and at a second opposite end () is coupled to a locking actuator (). A locking tooth () is moreover positioned between the first end () and the second end (). A method for activating an actuator assembly for a vehicle brake is furthermore presented.
