Apparatus for brake actuation

An apparatus for actuating a brake of a vehicle, comprising an electric motor;

• a coupling element operatively coupled movement-wise with the electric motor, linearly movable, connectable to a brake tensioning mechanism and transferrable by the electric motor in an energized state out of a braking position into a release position;
• an electrically actuated blocking device for a block on movement of the coupling element at least in the release position and having a spring energy store coupled movement-wise with the coupling element such that, in a release position of the coupling element, the store assumes a position to store spring energy, and, when the block on movement is overridden, the store transfers the coupling element into the braking position by released spring energy, wherein the blocking device is mechanically holdable in a blocking position thereof, effecting the block on movement, and is actuatable electrically, and optionally mechanically, actuatable for overriding the block on movement in the release position of the coupling element, wherein the blocking device has a movable blocking element which, in a blocking position thereof, blocks a movement of the coupling element and is moved out of the blocking position by electrical and optionally mechanical actuation, in the blocking position, the blocking element blockingly acts on a motor drive shaft, and wherein the blocking device has a blocking mechanism with a toothed blocking wheel connected in a rotationally fixed manner to the motor drive shaft, and a blocking pawl arranged to be brought into engagement with the blocking wheel to be effective as a blocking element.
