PURPOSE:To permit the suspension lock and jack-up by controlling the attitude of a car by the hydraulic cylinders installed onto the front, rear and intermediate axles and permitting a part of hydraulic cylinders to perform oil lock and raising of rear wheels. CONSTITUTION:An attitude controller is constituted of a suspension mechanism I, control mechanism II, and a pressurized-oil feeding/discharging mechanism III. In the suspension mechanism I, hydraulic cylinders SA1-SA8 are installed onto the front, rear and intermediate axles FA, RA, NA1, and NA2, and car height sensors S1-S4 are installed onto the hydraulic cylinders SA1-SA4, respectively. Accumulators Q1-Q6 are installed between the hydraulic cylinders SA1-SA4 and SA5-SA8, and lock valves VL1-VL4 are installed between the piston side chamber (b) of the hydraulic cylinders SA1-SA4 and the accumulators Q1-Q4. Further, the rise, i.e., jack-up of rear wheels is permitted by operating only the hydraulic cylinders SA3 and SA4 of the rear-wheel axle RA. |
