2112671 9301063 PCTABS00019 A vehicle having a load support body (5), and a pair of front ground engaging wheels (1, 2) and a pair of rear ground engaging wheels (3, 4) connected to the body (5) to support same and each wheel being displaceable relative to the body in a generally vertical direction. A double acting fluid ram interconnected between each wheel (1, 2, 3, 4) and the body (5) each ram including first (17a, 18a)(13a, 14a) and second (17b, 18b)(13b, 14b) fluid filled chambers on opposite sides of the ram piston, said first and second chambers oppositely varying in volume in response to vertical movement between the respective wheels and the body. Respective first fluid communicating conduits (10, 10a) connecting said first chambers (17a, 18a)(13a, 14a) of the front and rear wheels (1, 2, 3, 4) on the same side of the vehicle to provide respective first individual fluid circuits between the interconnected first chambers (17a, 18a)(13a, 14a), and respective second fluid communicating conduits (8, 8a) connecting the second chambers (17b, 18b)(13b, 14b) of the front and rear wheels (1, 2, 3, 4) on the same side of the vehicle to provide respective second individual fluid circuits between interconnected second (17b, 18b)(13b, 14b) chambers. Respective further conduits (35, 36) are provided interconnecting the first fluid circuit (10, 10a) on each side of the vehicle to the respective second fluid circuit (8, 8a) on the opposite side of the vehicle. The two front wheels (1, 2) of the vehicle are connected to the body by respective additional fluid rams (11, 12) defining respective third fluid chambers. The third fluid chambers being interconnected by a third conduit (7). Each of the conduits (10, 10a, 7) and preferably conduits (8 and 8a) have an accumulator (21, 22, 25, 26,...) or other resilience inducing device to accommodate fluid displaced from the rams in the circuit, and provide resilience to the system. |
