Abstract

1500741 Hydropneumatic suspension systems SOC NOUVELLE DES ATELIERS DE VENNISSIEUX 28 July 1975 [13 Sept 1974] 31497/75 Heading B7D In a suspension for a vehicle carrying a crane and comprising as shown in Fig. 1 hydraulic jacks 1 each having upper and lower chambers 2, 3 connected to a hydropneumatic accumulator 5 and a pressurized fluid reservoir 6 respectively, and a height regulating valve 10 having a first output 11 connected to the chamber 1 through a piloted one-way valve 13 and a second output 14 connected to the pilot circuit of the valve 13, there is provided as shown in Fig. 3 in the connection between the pressurized fluid reservoir 6 and the chambers 3 a piloted one-way valve 18 which has its pilot circuit connected to the chambers 2. The height regulating valve 10 has a neutral position in which both outputs 11, 14 are connected to a reservoir 6 so that the volume of fluid in the chambers 2 is held constant by the one-way valve 13, and also has raise and lower positions in which the output 14 is connected to the reservoir 6 and the output 11 supplied with pressurized fluid from a pump 8 or vice versa so that the volume of fluid in the chambers 2 is increased or decreased respectively. The one-way valve 18 and a valve 19 for isolating the accumulator 5 enable the suspension to be locked at any height, the valve 19 when closed preventing flow of fluid between the chambers 2 and the accumulator and the valve 18 preventing flow from the chambers 3 to the reservoir 6. The chambers 2 may be connected to the output 14 from the valve 10 through a calibrated one-way valve 21 which opens at a higher pressure than the pilot pressure of the valve 13 so that fluid from the pump 8 can be supplied to the chambers 2 to raise the axles or wheels associated with the jacks. In a vehicle having each jack or at least the jacks associated with the wheels on opposite sides separately controlled, the vehicle can be brought to a horizontal position on uneven ground by means of the jacks before being supported by stabilizer beams or arms, and the wheels or axles can then be raised from the ground during operation of the crane.
