ABSTRACT:
A hydromechanical power splitting transmission for use between the prime mover and the axle power train of a vehicle having a planetary differential drive with at least two series of planetary wheels, two sun wheels, a web and annulus, a drive input shaft and a drive output shaft, connected with different shafts of the planetary differential drive. There are furthermore at least first and second hydrostatic machines, which in at least one operational range are connected with one shaft of the planetary differential drive and at least the first of the hydrostatic machines is able to be switched over from its own shaft to another on changing the operational range by clutches, while the second hydrostatic machine is at least substantially stationary. In the operational state of the vehicle in which the ratio of n.sub.output to n.sub.input >approximately 50%, the first hydrostatic machine is connected to the transmission output shaft via one of two speed change devices of different size, selectively operated by a two way clutch. The larger of the two change speed devices is used for forward travel at creep speed and predominantly for reverse of the vehicle and is switched over into this drive ratio when the transmission is stationary.
