Title: Improvements in hydrodynamic road wheel suspension systems for vehicles
IPC: B60G21/06
Filed: 1957-10-11
Abstract: 820,194. Preventing lateral canting. DAIMLER-BENZ A. G. Oct. 11, 1957 [Oct. 16, 1956], No. 31905/57. Class 108(2) A hydro-pneumatic suspension system for a road-vehicle has fluid pressure transmission pipes 15a, 15b leading from each front wheel suspension to an operative member in a central compensating device 16. This member is responsive an increase in pressure in either one of the pipes 15 and operative for transmitting such increase to the other pipe 15. Similar pipes 15c, 15d leading from each of the rear wheel suspensions to a second operative member similar to the first member has the two operative members mechanically connected together so that when one wheel moves upwards towards the chassis the wheel diagonally opposite moves in the same direction and the other two wheels move in the opposite direction. The front wheels are connected to piston rods 11a, 11b, Fig. 2, and the rear wheels to rods 11c, 11d. In operation when the left hand front wheel is moved up towards the chassis, piston 12a displaces hydraulic liquid 13a upwards putting the liquid in pipe 15a under pressure and moving piston 19, and with it piston 18, downwards. Liquid is therefore displaced into pipes 15b, 15c so that pistons 12b, 12c and their corresponding wheels move down with respect to the vehicle chassis, whilst liquid from body 13d flows into the space behind piston 18 so that piston 12d and the right hand side rear wheel move upwards. "Oversteer" or "understeer" characteristics may be produced by adjusting the surface area of the piston acting on the hydraulic liquid by changing the thickness of the piston rod, thus producing different pressures in pipes 15a-15d, higher pressures being produced at front or rear wheels as required. Dipping movements about a transverse axis may be reduced by making piston rod 20 resilient. In the arrangement shown in Fig. 3, pipes 15a-15d communicate with bellows 24a-24d. Lever 27 having arms of unequal length produces a greater pressure in pipes 15a, 15b than in pipes 15c, 15d and hence roll about the longitudinal axis due to centrifugal force is absorbed more by the front wheels than the rear wheels. Fig. 4 shows an entirely pneumatic embodiment in which pistons 18, 19, Fig. 2, are replaced by diaphragms 28, 29 connected by rod 20. In Fig. 5 two gearwheel pumps 31, 32 and 33, 34, connected by shaft 35, pump hydraulic fluid from pipe 15a to pipe 15b and from 15d to 15c or vice versa as required. Due to the different distances between the axes of wheels 31, 32 and 33, 34, the front outside wheel is again more heavily loaded during cornering thus producing an "understeer" characteristic.

Title: Automatic valve systems
IPC: F15B13/02
Filed: 1973-07-04
Abstract: 1423785 Hydrostatic transmission control; valves DEERE & CO 4 July 1973 [4 July 1972] 31910/73 Headings F2W and F2V  In a hydrostatic transmission wherein a variable displacement swash-plate pump, which has its displacement varied in accordance with system pressure, supplies a pair of loads through lines 166, 172, an automatic control valve 98 successively closes outlet 108, 106 connected to the loads as the pump supply pressure 96 falls. The automatic valve 98 comprises a valve spool 132 which is biased to the right by springs 136, 138 and is moved left to the position shown by pump delivery pressure acting in a chamber 154 on a land 124. In the position shown an inlet 104 is connected to the outlet 106 and through an internal duct 170 in the valve spool to the outlet 108. On a reduction of pump delivery pressure the springs 136, 138 move the valve spool 132 right to close the outlet 108 and on a further reduction in pump delivery pressure the spring moves the valve spool further right to additionally close the outlet 106. As the valve spool moves right a spring 206 rotates the spool to move a pin 188 carried by the spool through a gate 198 which prevents automatic return movement of the spool to the left. A knob 184 fast with the valve spool 132 may be rotated to move the pin 188 through the gate 198 to permit leftward movement of the valve spool. The knob 184 additionally indicates the setting of the valve 98. The pump supplies the inlet 104 through a one-way valve 92 and a parallel throttle valve 94. The outlet 106 is connected to its load through an electromagnetically operated valve 168. One of the outlets may be connected through a reversing valve and a series-parallel valve to motors driving the wheels of a tractor. The transmission may be an auxiliary drive to the front wheels of the tractor.
