The invention discloses a damper (112). The damper comprises a pressure tube (122) and a piston (128). The piston (128) defines a rebound chamber (130) and a compression chamber (132). The damper (112) also includes a piston rod (134) that reciprocates with the piston (128). The damper (112) includes a sealing ring (308) slidably disposed about the piston rod (134). The sealing ring (308) includes a locking mechanism (360) adapted to lock the sealing ring (308) around the piston rod (134). The sealing ring (308) also includes an inner surface (326) having a plurality of concave surfaces (328) and a plurality of convex surfaces (330). Each of the plurality of concave surfaces (328) is positioned adjacent to a corresponding convex surface (330) of the plurality of convex surfaces (330). The sealing ring (308) also includes an upper surface (334) extending between the outer surface (336) and the inner surface (326). The upper surface (334) defines a plurality of channels (340). The sealing ring (308) also includes a groove (338) and a drain (374) for tuning energy dissipated by the damper (112) during the rebound stroke to help reduce noise.
本发明公开了一种阻尼器(112),该阻尼器包括压力管(122)和活塞(128)。活塞(128)限定回弹腔室(130)和压缩腔室(132)。阻尼器(112)还包括与活塞(128)一起往复运动的活塞杆(134)。阻尼器(112)包括密封环(308),该密封环可滑动地设置于活塞杆(134)周围。密封环(308)包括锁定机构(360),该锁定机构适于将密封环(308)锁定于活塞杆(134)周围。密封环(308)还包括具有多个凹状表面(328)和多个凸状表面(330)的内表面(326)。多个凹状表面(328)中的每一者定位成相邻于多个凸状表面(330)的对应凸状表面(330)。密封环(308)还包括在外表面(336)和内表面(326)之间延伸的上表面(334)。上表面(334)限定多个通道(340)。密封环(308)还包括凹槽(338)和排放部(374),以用于调谐在回弹行程期间由阻尼器(112)所耗散的能量以帮助降低噪声。
