PURPOSE:To improve the turning property of the vehicle by a method wherein rear wheels are steered into the reverse phase of front wheels at a speed lower than a predetermined speed of the vehicle by utilizing the power assist pressure of a power cylinder in the power steering device. CONSTITUTION:Connecting rods 7, 27 are connected to the rear ends of respective knuckle arms 2, 22, which support the front wheels 1 and the rear wheels 21 through bearings, through tie rods 5, 25. The power cylinder 10 and a cylinder 30 are provided at the middle parts of the connecting rods 7, 27 so that pistons 8, 28, secured to the rods 7, 27, are fitted slidably into the cylinders. Coil springs 33, 34 are accommodated in the left and right chambers 31, 32 of the cylinder 30 under compressed conditions to hold the connecting rod immovable when the pressures of oil, applied to respective chambers 31, 32 are lower than a predetermined pressure. The right chamber 12 of the cylinder 10 is communicated with the left chamber 31 of the cylinder 30 through a tube 41 while the left chamber 11 of the cylinder 10 is communicated with the right chamber 32 of the cylinder 30 through the tube 42. |
