The pedal is pre-stressed by a spring loader means in a direction opposite to the direction of operation. The invention also has a stroke simulator connected to the actuation pedal for transmitting the force. The stroke simulator cooperates with a damping device for defining the setting of a predetermined force-stroke characteristic curve. In order to flexibly adapt the characteristic curve of the force and stroke of the actuating pedal (1) to a predetermined course, the present invention provides that the damping device is configured as a magnetic fluid damping device (10).

Note that the above-mentioned constant throttle effect of the through hole is observed.
Friction that occurs in cup-shaped spring devices and causes small hysteresis is considered to be another disadvantage.

The actuation pedal or brake pedal 1 has a foot plate 2 to which a flexible resistance arm 3 rotatably provided via a tiltable rotary shaft 4 is mounted. The characteristic curve of the appropriate progressive force and stroke of the brake pedal 1 is reproduced by the spiral spring 5. The spiral spring 5 is pre-loaded in a direction opposite to the direction of operation of the brake pedal 1, is firmly fixed thereto, and has a spring stop 6
