In an actuator or electro-mechanical brake unit, preferably for rail vehicles, a roller (25), which is connected to a member for transmitting a resulting force from the actuator, is acted on by constant forces from two directions forming an angle with each other. These forces stem from opposite ends of a spring (13). One of the forces is transmitted directly to the roller and the second one via a lever (17). A control yoke (27) for the roller can be transferred along the periphery of the roller by means of an electric control motor (31) for creating different leverages and thus different resulting forces. |
