PURPOSE:To improve turning ability during low speed running and stability during high speed running, by a method wherein an actuator is located between the one end side of a leaf spring, the other end side of which is pivotally supported to a car body frame, and a car body frame, and the actuator is controlled according to the steering angle of a front wheel. CONSTITUTION:A pair each of shackle members 26L, 26R, 28L, and 28R is mounted to each of the front, the rear, the right, and the left of a car body frame 22, and a pair of leaf springs 30L and 30R is mounted on each of both sides. A pair of left and right hydraulic cylinders 38L and 38R is mounted to the rear of the car body frame 22, and piston rods 40L and 40R are rotatably mounted to the shackle members 28L and 28R, respectively. Meanwhile, a detecting signal from a steering angle sensor 52 for detecting the steering angle of a pair of left and right front wheels 2L and 2R is inputted to a control unit 50. From the control unit 50, drive signals for oil pumps 46L and 46R are outputted so as to actuate the hydraulic cylinders 38L and 38R based on a steering angle signal. |
