REAR WHEEL STEERING FOR VEHICEL WITH TORSION BEAM AXLE

PURPOSE: A rear wheel steering device of a torsion beam axle vehicle is provided to reduce a minimum rotation radius of a vehicle in low speed and to improve driving stability and turning stability in high speed. CONSTITUTION: A rear wheel steering device of a torsion beam axle vehicle comprises a rear wheel knuckle(5), a screw unit, a linear movement unit(11), and a link(13). The rear wheel knuckle supports a rear wheel(1) to be moved and is rotatably installed in a trailing arm(3). The screw unit is formed in a torsion bar of a torsion beam axle type suspension device. The linear movement unit moves as relative screw motion with the screw unit and forms linear displacement on the torsion bar. The link is connected to the each rear wheel knuckle on both sides of the linear movement unit and transmits the linear displacement of the linear movement unit to the rear wheel knuckle.
