An air spring assembly includes a piston configured to couple to a suspension component; a top cap configured to couple to a vehicle frame; and a hollow guide tube having a first end coupled to the top cap and a second end provided with an aperture to the hollow. The piston passes through the aperture and is disposed at least partially within the guide tube. The assembly also includes a diaphragmdisposed at least partially within the guide tube, disposed between and attached to the piston and the top cap. The assembly further includes a seal member having an outboard portion coupled to the guide tube proximate the second end, an inboard portion coupled to the outer periphery of the piston, and a membrane extending between the outboard portion and the inboard portion. The membrane definesa rolling lobe disposed between the guide tube and the piston.
空气弹簧组件包括:配置成联接到悬架部件的活塞;配置成联接到车辆框架的顶盖;以及具有第一端部和第二端部的中空引导管,第一端部联接到顶盖,第二端部设置有中空的孔。活塞穿过孔且至少部分地设置在引导管内。所述组件还包括至少部分地设置在引导管内的隔膜,隔膜设置在活塞和顶盖之间且附连到活塞和顶盖。所述组件还包括密封构件,所述密封构件具有外部部分、内部部分和在外部部分和内部部分之间延伸的膜,外部部分在所述第二端部附近联接到引导管,内部部分联接到活塞的外周边。所述膜限定设置在引导管和活塞之间的滚动凸耳。
