Abstract

1360399 Reciprocating pumps and motors GENERAL ELECTRIC CO 22 Sept 1971 [25 Sept 1970] 44158/71 Heading F1A [Also in Division F2] A tracked vehicle steering transmission comprises an input drive-shaft 1 and right and left output shafts 4, 5, driven through a steering transmission 3 either directly through gearing 30-32 or through an increaser transmission 2. Each transmission includes a piston and cylinder hydrostatic pump motor unit 35, 37 and 36, 38 capable of infinitely variable speed and reverse control. Each output shaft is driven through first and second planetary gears and at slow speeds, shaft 39 drives suns 40, 41 to drive planets 42, 43 with ring gears 37, 38 controllably driven in either direction by units 35-38 with the carrier of each first planetary gear driving suns 44, 49 which through planets and carriers 47, 51 drive the output shafts 4, 5 while the rings 46, 50 are held with the increaser transmission held by a brake 29. At higher speeds the brake 29 will be released and the hydrostatic unit in the increaser transmission will be controllably driven to drive the rings 46, 50 of the second planetary gears to increase the speed of the output shafts 4, 5. An hydraulic controller Fig. 3 has an accelerator pedal position signal acting on an input shaft 62, connected to one end of a bar 66 and an engine speed signal represented by an external pump pressure, acting on the other end of the bar 66 to control a pilot piston 71 which causes a power piston 73 to position a control plate 74. A manual selector 84 sets the desired range and the plate 74, by cams 75-77, actuates the control valves of the hydrostatic units. A steering wheel signal given to the plate 74 will cause the steering arm 78 to pivot to give more stroke to the left or right valve of the steering hydrostatic units. Each hydrostatic unit Fig. 2 comprises identical pump and motor units each with a cylinder 6 having ball pistons 8 in bores 7 contained in a ball pump race 9 pivotally mounted at 10 the output of the unit giving infinitely variable speed in reversible directions by varying the eccentricity of the ball race 9 of one or other or both of the units by valve means 19 controlling a fluid motor 15.
