Abstract

In a clutch operating system, a signal transmitter device (1) is connected via pressure medium in a pressure-medium circuit (5) between a clutch pedal (3) with the master piston unit (31) and the slave piston unit (41) of the clutch (4). This signal transmitter device generates a pressure signal (11) when, after a gear-change, a gear is again engaged in the gearbox causing an electromagnet (15) to be energised. This signal is transmitted via the pressure-medium circuit (5) to the master piston (32) and thus to the clutch pedal (3) as a tactile signal. To match this signal to the driver's requirements, an adjusting device (13), with which the signal strength can be regulated, is fitted to a pressure piston (12). The pressure piston may be connected to a larger piston (Fig 2) actuated pneumatically from an air reservior via a pressure reducing valve and under the control of a solenoid valve. <IMAGE>
