The invention relates to an actuation device for a brake (), for applying an output force (F) to means () which generate braking force, depending on an input parameter (F), comprising a lever () and a force generator () which brings a force (F) to bear on the lever () at an effective angle (&#x3b1;), relative to the longitudinal axis of the lever (). 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.

Actuating device for a brake

The electromagnetic coil according to the invention has a coil core, a winding of coil wire and two contact pins, the contact pins being secured to at least one resilient holding member and being movable relative to the coil core. The holding member is formed in a unitary manner with the coil core, and the ends of the coil wire are secured to the movable/resilient contact pins.
