The invention relates to a diaphragm corrugated pipe double-cavity front air suspension, and belongs to the technical field of vehicle suspension devices. The front air suspension comprises a first diaphragm corrugated pipe and a second diaphragm corrugated pipe, wherein the top and the bottom of the first diaphragm corrugated pipe are respectively fixed with a top seat and a bottom seat; the top of the second diaphragm corrugated pipe is fixed with the top cover, and an annular plate is fixed at the bottom; a piston rod of the damper sequentially penetrates through the base, the annular plate and the top cover from outside to inside and is fixed to the top cover. A main air cavity is defined by the inner wall of the first diaphragm corrugated pipe, the outer wall of the second diaphragm corrugated pipe, the lower surface of the top seat, the lower surface of the top cover, the upper surface of the base, the first section outer wall of the piston rod and the outer wall of the annular plate. An auxiliary air chamber is defined by the inner wall of the second diaphragm corrugated pipe, the lower surface of the top cover, the outer wall of the second section of the piston rod and the inner wall of the annular plate; the first air hole and the second air hole are communicated with the main air cavity and the auxiliary air cavity respectively and then are inflated and deflated, and double adjustment of the height and the rigidity of the front air suspension is achieved.
本发明涉及一种膜片波纹管双腔前空气悬架,属于车辆悬架装置技术领域。该前空气悬架包括第一膜片波纹管和第二膜片波纹管,第一膜片波纹管顶部和底部分别与顶座和底座固定;第二膜片波纹管顶部与顶盖固定,底部固定有环形板;阻尼器的活塞杆从外向内依次穿过底座、环形板和顶盖并固定于顶盖;由第一膜片波纹管内壁、第二膜片波纹管的外壁、顶座下表面、顶盖下表面和底座上表面、活塞杆的第一段外壁和环形板外壁围成有主气腔室;由第二膜片波纹管的内壁、顶盖下表面、活塞杆的第二段外壁和环形板内壁围成有副气腔室;第一气孔和第二气孔分别连通主气腔室和副气腔室后进行充放气,实现对前空气悬架的高度和刚度的双重调节。
