摘要： A torque split power transmission is described, having an input shaft (2) and an output shaft (4), said input shaft (2) and said output shaft (4) for torque splitting purposes in a first mechanical drive line having a fixed ratio of transmission and in a second drive line having an infinitely variable ratio of transmission (5) between a drive shaft (10) and a driven shaft (13) being in connection with a planetary gear (3). The shaft being in direct connection with the planetary gear is locked at least approximately once to standstill over the whole range of revolutions. To reduce power losses at special working points the infinitely variable transmission (5) being located in the second drive line is free of any torque transmission but keeps a supporting function when reaching a ratio of transmission at which the shaft being connected with the planetary gear at least approximately stands still.

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)).
