Steering device for vehicle

Abstract

Abstract PURPOSE:To improve steering property by a method wherein front wheels and rear wheels are turned into reverse phases upon running at a low speed by utilizing the assist power of a power cylinder to improve the turning property of the vehicle while all wheels are turned into the same phase upon running at a high speed by utilizing side force effecting on the rear wheels. 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 middel 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, a lower arm 45 for the rear wheel is connected to the fron end of the knuckle arm 22 for the rear wheel through a bearing and the other end thereof is connected to the body of the vehicle by a pivotal pin 49 through an elastic bush 46. 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.
