Abstract
Abstract A swing arm suspension for automotive vehicle has a suspension arm pivotably connected to a suspension member for rotation about a substantially horizontal pivot axis. A lateral rod is connected to the suspension arm at one end thereof via a bushing and to a suspension member at the other end via another bushing. The position where the lateral rod is connected to the suspension member is offset from an extension of the pivot axis of the suspension arm. The position is chosen such that the lateral rod serves to provide rolling compensating force for the suspension to satisfactorily and successfully restrict roll or compliance steering in the toe-out direction and to prevent positive camber. The lateral rod is positioned to be connected to the suspension member at such a position as to cause toe-in and/or negative camber.
