Abstract
An independent wheel suspension for a motor vehicle according to the present disclosure includes vehicle body structure, a wheel support member and upper and lower suspension arms which connect the body structure to the wheel support. A resilient pivot couples the outer end of the upper arm to the wheel support member and includes a ball and socket joint which has its socket secured to the arm and its ball connected to the wheel support by an annular resilient bushing. The resilient pivot isolates vibrations of the wheel support member from the upper arm. The resilient pivot also allows horizontal wheel movement when the wheel strikes a minor road obstacle such as tar strip or expansion joint in concrete pavement. Such horizontal wheel compliance attenuates the shock of the impact.
