ABSTRACT:
An activating device, in particular a clutch activating device for vehicles equipped with a clutch pedal mounted on a stationary pivot. The clutch pedal is connected to a drive mechanism controlling the activating force of the pedal. The drive mechanism includes a control lever on which an intermediate lever connected to the clutch pedal is held. The drive mechanism includes a first lever joint with the control lever, which is acted upon by a compression spring and which is swivel mounted on a stationary pivot, as well as the attached intermediate lever. This forms a second lever joint with an activating lever of the pedal. The assembly forms an increasing effective lever arm when the pedal is depressed such that the activating force of the clutch pedal is maintained at a substantially constant level for at least a portion of the clutch disengaging process.
