A practical and simple suspension system with connected left and right dampers is proposed to concurrently improve maneuverability/stability and ride comfort for automobiles. Because this suspension apparatus is able to produce both a spring characteristic as well as a damping characteristic, with bouncing/pitching and with rolling separately, a degree of freedom peculiar to a suspension design can be increased. When this apparatus is applied to automobiles, it becomes easy to improve these contradictory vehicle performances. It has a simple constitution in which each damper on the left and right wheels is joined with hydraulic piping of X form. And it has higher reliability and energy conservation effect in comparison with general electronic control suspension systems, and therefore does not require the electronic devices and the drive resources of actuator. In this paper, we show a design method of this system with coordinated right and left suspension dampers. Furthermore, we report the results of computer simulation confirming that circular turning performance is improved by the proper adjustments of the roll stiffness with nonlinear characteristics to roll angle, and of the roll damping characteristics in the front and rear suspensions.
