Abstract: 1515157 Hydrostatic transmission control ROBERT BOSCH GmbH 30 Oct 1975 [19 Nov 1974] 45057/75 Heading F2W A hydrostatic transmission comprises two pumps, 10, 11, supplying respective motors 45, 47, the pumps being driven by a common shaft 10<SP>1</SP> whose speed is sensed by a transmitter 54 which supplies a signal to an electronic controller 20, this controller also receiving signals from devices 18, 21 which sense the pump displacements and operating valves 24 and 26 to control these displacements and prevent stalling of the driving engine, the controller 20 additionally receiving signals from devices 49, 51 which sense the positions of manuallyoperated control valves 38, 39 which control the supply of fluid to the motors 45, 47 so that when these valves 38, 39 are set to give equal supply to the motors the controller 20 will control the pumps so as to maintain this equal supply. The pumps are radial piston type. The pumps are adjusted by servos 52, 53 which are supplied by pressure regulating valves 16, 17 each of which is supplied with the output pressure of its respective pump through a line 33 or 34, the magnetically-operated valves 24, 26 supplying, when operated, the higher output pressure from a shuttle valve 30 to the pressure regulators 17, 16. The motors 45, 47 drive tracks on opposite sides of an excavating vehicle. The controller 20 can additionally adjust the pumps 10, 11 in response to pressure fluid requirements for additional hydraulic equipment such as hydraulic cylinders for operating a jib, arm or bucket of the excavator (Fig. 2, not shown).

A self-pumping hydro-pneumatic suspension unit particularly for motor vehicles comprises a supplementary device for influencing the working pressure and a pressure relief valve 25 in the high pressure chamber, the valve opening at a predetermined pressure. In the construction shown the suspension unit includes two coaxial cylinders 1, 9, the space therebetween being divided by a partition 13 to which is riveted the relief valve 25. A piston 6 works in the inner cylinder 9, the cylinder chamber 21 of which connects with the high pressure chamber 16 through channels 19 and/or throttle valves 20, a recess 18 and channels 17. A diaphragm 14 separates a gas cushion 15 from the high pressure chamber. A storage chamber 11 beneath the partition communicates with a pump chamber 22 beneath the piston through a suction valve, the pump chamber, in turn, communicating with the cylinder chamber 21 through a pressure valve 24. The normal riding level of the unit is determined by a control port 26 which co-operates with the piston 6. The pressure relief valve comprises a differential piston member which is variably spring-loaded such that a valve seat thereon is disengaged by a valve member at the pre. determined pressure (Fig. 2, not shown). The fluid path in the valve is restricted and comparatively long such that the instantaneous increases in pressure due to dynamic overload do not actuate the unit. In a further embodiment (Fig. 3, not shown) the storage chamber is separated from a further gas cushion by a diaphragm. The working piston is provided with a bore in which works a pumping piston which is suspended from the upper end of the unit in a gimbal suspension. The pumping piston is also provided with a bore which communicates with the high pressure chamber at its upper end and with the bore or pumping chamber of the working piston at the other through a variably spring-loaded ball relief valve.
