The invention relates to a suspension thrust bearing device (10) for use with a suspension spring (3) in an automotive suspension strut of a vehicle. The device (10) comprises a bearing (20, 30, 40) having upper annular bearing members (20, 42) and lower annular bearing members (30, 41) in relative rotation; and a damping element (70) made of resilient material and interposed between the lower annular bearing members (30, 41) and the suspension spring. The damping element includes at least one deflecting flange (73) for reducing any ingress of water and other pollutants between the upper and lower annular bearing members. The damping element is provided with an annular groove (74) open axially towards the suspension spring, the annular groove radially defining a spring support surface (75) on an inner side, and the deflecting flange on an outer side. The deflecting flange has a frustoconical shape directed axially towards the suspension spring.

本发明涉及一种与车辆的汽车悬架支柱中的悬架弹簧(3)一起使用的悬架推力轴承装置(10)。所述装置包括：轴承(20、30、40)，具有相对旋转的上环形轴承构件(20、42)和下环形轴承构件(30、41)；以及减震元件(70)，由弹性材料制成，且介于下环形轴承构件(30、41)与悬架弹簧之间。减震元件包括至少一个偏转凸缘(73)，该至少一个偏转凸缘用于减少水和其他污染物进入所述上环形轴承构件与所述下环形轴承构件之间。减震元件设置有在轴向上朝向悬架弹簧开口的环形槽(74)，环形槽在内侧在径向上限定弹簧支撑表面(75)且在外侧在径向上限定偏转凸缘。偏转凸缘具有在轴向上指向悬架弹簧的截头圆锥形形状。
