用于车辆悬架的止推轴承
摘要：
悬架支柱(10)包括螺旋弹簧(14)和悬架止动器(18)。该止动器(18)由包括金属垫圈(22)和金属下垫圈(24)的滑动轴承或滚柱轴承(20)旋转。止动器包括单件式杯状物(34)，该单件式杯状物具有上表面(36)和下表面(42)，该上表面包括与轴承的下垫圈(42)接触的区域(38)，该下表面包括平面外环形肩部(44)和至少部分为圆柱形的环形座(46)，该环形座径向地向外翻且与外肩部(44)一起界定用于螺旋弹簧(14)的顶端的外围环形支撑区域(47)。单件式杯状物(34)的上表面(36)包括径向地位于接触区域外的加强肋(40、140)。单件式杯状物(34)包括隔离物(49)，该隔离物形成了构成容纳面(54)和环形座(46)的环形折叠(48)，该容纳面(54)径向地位于在环形座(46)内，单件式杯状物(34)的上表面(36)包括延伸到隔离物(49)的环形折叠(48)中的加强肋(40、140)。
摘要（英）：

A suspension strut (10) comprises a coil spring (14) and a suspension stop (18). The stop (18) is rotated by a plain bearing or roller bearing (20) comprising a metal top washer (22) and a metal bottom washer (24). The stop comprises a unitary cup (34) having an upper face (36) comprising an area (38) of contact with the bottom washer (24) of the bearing and a lower face (42) comprising a planar outer annular shoulder (44) and an at least partially cylindrical annular seat (46) turned radially outwards and delimiting, with the outer shoulder (44), a peripheral annular support area (47) for the top end of the coil spring (14). The upper face (36) of the unitary cup (34) comprises reinforcement ribs (40, 140) located radially outside the contact area. The unitary cup (34) comprises a partition (49) forming an annular fold (48) constituting the containment face (54) and the annular seat (46), the containment face (54) being located radially within the annular seat (46), the upper face (36) of the unitary cup (34) comprising reinforcement ribs (40, 140) extending into the annular fold (48) of the partition (49).
