Suspension thrust bearing device

The invention concerns a suspension thrust bearing (1) for use with a suspension spring in an automotive suspension strut. The suspension thrust bearing (1) comprises a bearing (5) with an annular upper part (3) and a annular lower part (4) in relative rotation one to the other, a lower support surface (83) being comprised by the lower part (4) that axially supports an upper end of a suspension spring (2) by the intermediate of a damping device (8) made from resilient material. The resilient material of the damping device (8) is melt in its preformed state with gas. After being molded, the melt material of the damping device (8) comprises an outer skinny layer (85) and an inner foam body (84), the density of said outer skinny layer (85) being strictly greater than the density of the inner foam body (84). 本发明涉及种在机动车悬架支柱中与悬架弹簧起使用的悬架止推轴承(1)。所述悬架止推轴承(1)包括：轴承(5)，其具有相对于彼此旋转的环形的上部(3)和环形的下部(4)；下支撑表面(83)，其由所述下部(4)构成，所述下部(4)通过作为中间物的由弹性材料制成的阻尼装置(8)轴向地支撑悬架弹簧(2)的上端。阻尼装置(8)的弹性材料在其预成型状态时借助气体熔化。在成型之后，阻尼装置(8)的熔融材料包括外皮层(85)和内泡
