The invention relates to a double-cavity diaphragm corrugated pipe rear air suspension, and belongs to the technical field of configuration of vehicle suspension devices with gas spring characteristics. The rear air suspension comprises a first diaphragm corrugated pipe arranged between a top seat and a base and a second diaphragm corrugated pipe located in the first diaphragm corrugated pipe, a top cover is arranged on the top seat in a sealed mode, the top of the first diaphragm corrugated pipe is fixed to the top seat, the bottom of the first diaphragm corrugated pipe is fixed to the base, and the top of the second diaphragm corrugated pipe is fixed to the top cover. A blind plate is fixed at the bottom of the second diaphragm corrugated pipe; a main air cavity is defined between the inner side of the first diaphragm corrugated pipe and the outer side of the second diaphragm corrugated pipe, an auxiliary air cavity is defined among the inner wall of the second diaphragm corrugated pipe, the top cover and the blind plate, a first air hole communicated with the main air cavity is formed in the top base and the top cover in a penetrating mode, and a second air hole communicated with the auxiliary air cavity is formed in the top cover. According to the rear air suspension, the main air cavity and the auxiliary air cavity are inflated and deflated, so that the height and rigidity of the rear air suspension can be adjusted.

    本发明涉及一种双腔膜片波纹管后空气悬架,属于具有气体弹簧特性的车辆悬架装置的配置技术领域。该后空气悬架包括设于顶座与底座之间的第一膜片波纹管和位于第一膜片波纹管内的第二膜片波纹管,顶座密封设有顶盖,第一膜片波纹管顶部与顶座固定,第一膜片波纹管底部与底座固定,第二膜片波纹管顶部与顶盖固定,第二膜片波纹管底部固定有盲板;在第一膜片波纹管内侧与第二膜片波纹管外侧之间围成有主气腔室,在第二膜片波纹管内壁、顶盖和盲板之间围成有副气腔室,贯穿顶座和顶盖开设有与主气腔室连通的第一气孔,顶盖上开设有与副气腔室连通的第二气孔。该后空气悬架通过对主副两个气腔室进行充放气,实现对后空气悬架的高度和刚度的双重调节。
