VEHICLE BEHAVIOR CONTROL DEVICE BY USING A SHOCK ABSORBER FOR IMPROVING RIDING COMFORT AND OPERATION STABILITY BY CONTROLLING OPTIMALLY SPRING CHARACTERISTIC OF AN UPPER BUSH ACCORDING TO A TRAVELING STATE OF THE VEHICLE
PURPOSE: A vehicle behavior control device by using a shock absorber is provided to control wheel bump stroke and wheel rebound stroke of the shock absorber for optimal operation stability and riding comfort by changing hard or softly the spring characteristic of a bump stopper according to a traveling state of the vehicle. CONSTITUTION: A vehicle behavior control device by using a shock absorber is composed of the shock absorber having a spring(2) placed at a spring bracket(2') and a cylinder(1) filled with actuating fluid and combined to a vehicle body to generate damping force; a bump stopper comprising rubber lower and upper bushes(3,4) having spring characteristic for covering a piston rod of the cylinder of the shock absorber and relieving shock; a regulating unit(11) attached to the underside of the bump stopper to compress or extend the bump stopper and to generate magnetostriction for changing the spring characteristic that is set initially; and signal input units(20,20') for analyzing a signal according to vehicle traveling states and sending an electrical signal to generate magnetostriction by the regulating unit.
