摘要： A system operated by means of what is referred to as a clutch pedal is described, which adjusts the traction power of an infinitely variable, hydrostatic-mechanical transmission. The transmission contains at least one pump (1) and at least one motor (2), arranged in a hydraulic circuit. In order to reduce the traction power, pressure is leaked between the two sides of the motor (2) by reducing the pressure at the control parts (14a) of two proportional valves 14, 15 in respective lines bridging the motor (2).
The control parts (14a) of the proportional valves (14, 15) are connected via a shift valve (19) to an intermediate valve (24), the closing force of which is reduced as the clutch pedal (26) is opened (by means of a closing spring (36)).
