ABSTRACT:
A suspension strut for a motor vehicle in which a steering knuckle is supported by a housing of a telescopic damper. A piston rod projecting from the damper housing has a support flange secured to its free end to form part of a flexible mounting for a body portion of the vehicle. A helical suspension spring is seated at its lower end on an annular bracket carried by the damper housing and at its upper end on a spring support plate surrounding the piston rod. A needle-roller thrust bearing is interposed between the piston rod support flange and the spring support plate to accommodate rotary movement of the spring and support plate during steering maneuvers.
To provide a predetermined amount of bearing friction, a friction element in the form of a circular bead is arranged between the piston rod support flange and the spring support plate. The circular bead is formed as a part of a cage of plastic material serving to locate the individual needle rollers of the bearing.
