ABSTRACT:
An automotive strut type suspension system includes a pair of relatively telescopable members, one of which is attached to the vehicle sprung mass and the other of which is rotatable relative to the sprung mass, and a helical spring disposed around the relatively telescopable members. The spring is seated on the other telescopable member and bears at its opposite end against a retainer. A rigid bearing race is disposed on the sprung mass and includes race surfaces parallel to corresponding surfaces on the retainer. A dual function unitary bearing member is disposed between parallel surfaces on the bearing race and the retainer and accommodating relative rotation between the bearing race and the retainer the spring and the other telescopable member. The unitary bearing member is fabricated from plastic material which exhibits increased coefficient of friction with increased surface contact velocity so that rapid rotary oscillations between the bearing race and the retainer are effectively damped.
