PURPOSE:To reduce the dimension and weight of the whole device by performing the attitude control of a car and ground holding by installing hydraulic cylinders installed onto the front, rear and intermediate axles and accommodating pilot lock valves into the hydraulic cylinders in a main part. 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. Pilot lock valves VL1-VL4 are installed between the piston side chamber (b) of the hydraulic cylinders SA1-SA4 and accumulators Q1-Q4. While, in the pressurized-oil feeding/discharging mechanism III, a pump P for pumping up the oil in a tank T by the drive of an engine E, relief valve R for limitting the max. pressure of the pump P and a constant oil quantity, and a flow-rate control valve FV are provided. |
