ABSTRACT:
A bearing assembly is disclosed for supporting a coil spring, for example for an automobile suspension system. The bearing assembly includes an elastic support having a sloped spring supporting surface corresponding to the pitch of the spring. At the side opposite the spring, the elastic support is supported by a distance element. The distance element and elastic support are geometrically configured so that a uniform axial length of the elastic support member is disposed between the spring and the distance element over a substantial circumference of the coil spring. In certain embodiments, recesses are formed in the elastic support member for engaging with cams at the distance element, with the ends of the cams and the bottoms of the recesses dimensioned so that there is a constant height of the elastic support between the spring and the distance element. In other embodiments, continuous sloped surfaces are provided in both the distance element and the elastic support, again with a constant axial length of elastic support over a substantial portion of the circumference of the coil spring.
