PURPOSE:To make possible to steer a rear axle of a vehicle with a simple arrangement, by forming fluid chambers in each of couplings provided at both ends of each of torque rods for supporting the rear axles, and by feeding and discharging fluid into and from the fluid chambers to change the effective length between both couplings. CONSTITUTION:In a rear axle steering device in which a rear axle of a vehicle such as a truck or the like, are suspended from both ends of leaf springs, and both ends of the rear axle are coupled to a vehicle body through the intermediary of torque rods 26, respectively, ring-like couplings 33, 34 are provided at both ends of each torque rod 26, and are fitted therein with rubber bushings 35 each having its center section oscillatably supporting a connecting pin 37. Further, a pair of hydraulic chambers 41, 42 are formed in each rubber bushing 35 at positions on an axial extension of the torque rod 26, symmetrically with each other with respective to the center of the bushing, and therefore, the effective length L between the couplings 33, 34 is changed by feeding and discharging fluid into and from the hydraulic chambers 41, 42 through a change-over valve 38 to steer the rear axle. |
