Brake pedal for actuating an electric brake installation

摘要

The braking pedal (2) contains a foot plate (4), over which a power is transmitted to a mechanical component (12) which is re-shaped by the foot power and re-assumes its original form at a removal of the foot power, to move the foot plate to its starting position. The mechanical component consists of a stack of plate springs. The stack of plate springs is assembled from individual plate springs (14) with different indices, so that the plate spring stack has an altogether progressive index. The plate spring stack consists pref. of at least two partial spring stacks (12a, 12b) which comprise a different spring hardness, whereby one stack surrounds the other stack concentrically.
