Abstract

The invention relates to an actuation device for a brake (40, 41, 42, 43, 50), for applying an output force (FA) to means (40, 41, 42, 43, 50) which generate braking force, depending on an input parameter (FE), comprising a lever (1) and a force generator (7) which brings a force (FFeder) to bear on the lever (1) at an effective angle (α), relative to the longitudinal axis of the lever (1). Furthermore, an alternative actuating device for a brake is given, which permits a significant reduction of the power and energy requirements relative to direct-acting actuating devices. The above is achieved by means of a low-friction actuation characteristic as a result of the construction features of the actuating device and/or the selection of materials used. A preferred field of application is in electrically-driven braking systems on commercial vehicles.
