    • PURPOSE: A hydraulic damper is provided to contribute to an improvement in the ride quality of automotive vehicles by effectively reducing wide-ranging vibrations including high-frequency vibrations. CONSTITUTION: A hydraulic damper, comprising: a cylinder filled with hydraulic fluid; a piston slidably received in the cylinder through a piston ring; a piston rod having one end mounted to the piston and another end extending outwardly of the cylinder; a guide bush arranged on the side of the cylinder to slidably support the another end of the piston rod; a seal member arranged outwardly with respect to the guide bush, the seal member slidably contacting the piston rod to prevent leakage of hydraulic fluid from the cylinder, the seal member comprising a lip portion; and a friction member arranged inwardly with respect to the seal member, the friction member being mounted to one of the cylinder and the piston rod, the friction member slidably contacting another of the cylinder and the piston rod to produce friction greater than that produced at the seal member.
    • 目的:提供液压阻尼器,通过有效减少包括高频振动在内的宽范围振动,有助于提高机动车辆的行驶质量。 构成:液压阻尼器,包括:充满液压流体的气缸; 通过活塞环可滑动地容纳在气缸中的活塞; 活塞杆,其一端安装到活塞上,另一端延伸到气缸外部; 引导衬套,其布置在所述气缸的侧面上以可滑动地支撑所述活塞杆的另一端; 所述密封构件相对于所述引导衬套向外布置,所述密封构件与所述活塞杆滑动接触以防止液压流体从所述气缸泄漏,所述密封构件包括唇部; 以及摩擦构件,其相对于所述密封构件向内布置,所述摩擦构件安装到所述气缸和所述活塞杆中的一个,所述摩擦构件可滑动地接触所述气缸和所述活塞杆中的另一个,以产生比在 密封件。
