PURPOSE:To prevent the backward tilt of a chassis in acceleration by obtaining a driving torque repulsive force by detecting a rear-wheel load in acceleration and adjusting the amount of liquid in the cylinder of a front and rear wheel buffer apparatuses and varying the damping force and the spring constant of the buffer apparatus. CONSTITUTION:Each signal of a load sensor 15, car-height sensor 16, and a car-speed sensor 12 in the rear part of a chassis is input into a microcomputer 65. The microcomputer 65 calculates acceleration speed from the signal of the car-speed sensor 16 when the load sensor 15 shows a prescribed value or more, and said acceleration speed is compared with a prescribed value. When the acceleration speed is larger than the prescribed value, the solenoids 30a of the electromagnetic variable throttle valves 30 of the front and rear wheel suspensions 1 and 21, solenoid 11c of an electromagnetic throttle valve 11A, and the solenoid 11d of an electromagnetic opening and closing valve 11B are energized, and the electromagnetic direction switching valves 27 and 37 of the front and rear wheel suspensions 1 and 21 are operated to return the pressurized liquid in a front-wheel cylinder 7 to a liquid tank 31, and the pressurized liquid in an accumulator 36 is supplied into the rear-wheel cylinder 7. Thus, the backward tilt of the chassis in acceleration can be prevented. |
