ABSTRACT:
A pneumatic control device for a vehicle clutch has at least one clutch disk and includes a pneumatic cylinder operatively connected to the clutch disk operating the clutch disk as a function of pneumatic pressure applied to the cylinder. A displacement sensor measures an amount of travel of the clutch pedal and emits a signal based thereupon. An electronic package responsive to the signal from the displacement sensor outputs a control signal which follows a predetermined law as a function of the signal from the displacement sensor. A pneumatic circuit is connected to the pneumatic cylinder for supplying the pneumatic pressure thereto, the pneumatic circuit including an electropneumatic modulator which receives the control signal and outputs a pneumatic pressure as a function of the control signal.
