Suspension thrust bearing device

Abstract

The invention concerns a suspension thrust bearing for use with a suspension spring in an automotive suspension strut. The suspension thrust bearing provides a bearing with an annular upper part and a annular lower part in relative rotation one to the other, a lower support surface being provided by the lower part that axially supports an upper end of a suspension spring by the intermediate of a damping device made from resilient material. The resilient material of the damping device is molten in its preformed state with gas. After being molded, the molten material of the damping device provides an outer skinny layer and an inner foam body, the density of the outer skinny layer being strictly greater than the density of the inner foam body.
