The invention provides air supply equipment for an automobile air suspension. The air supply equipment comprises a compression unit and a drying and filtering unit, and is characterized in that a piston piece is movably installed in an air cavity and divides the air cavity into a first-stage compression chamber, an air inlet chamber and a second-stage compression chamber, the air inlet chamber iscommunicated with an air inlet pipe, the second-stage compression chamber is communicated with an air outlet, the piston piece is internally provided with an air duct and a first vent hole communicating the air inlet chamber and the first-stage compression chamber, and the piston piece is further provided with a second vent hole communicating the first-stage compression chamber and the air duct and a third vent hole communicating the second-stage compression chamber and the air duct; a connecting rod group is connected with the piston piece and is driven by a motor to drive the piston piece toreciprocate up and down; a filter shell is connected with a compression shell, an air outlet of the compression shell is communicated with the filter cavity, and a filter element is installed in thefilter cavity. According to the invention, a two-stage compression technology is adopted, the highest output gas can reach 21Bar, the pressure of the output air is high, and the adjusting sensitivityof an automobile air suspension system can be effectively improved; and functions are integrated, and the total volume is smaller.

    本发明提出了一种汽车空气悬架用空气供给设备,包括压缩单元和干燥过滤单元;活塞件活动安装在气腔内并将气腔分为一级压缩室、进气室、二级压缩室,进气室与进气管连通,二级压缩室与出气口连通,活塞件内设有通气道并设有连通进气室与一级压缩室的第一通气孔,活塞件上还设有连通一级压缩室与通气道的第二通气孔以及连通二级压缩室与通气道的第三通气孔;连杆组与活塞件连接且连杆组由电机驱动带动活塞件上下往复运动;过滤壳体与压缩壳体连接且压缩壳体的出气口与滤腔连通,滤芯安装在滤腔内。本发明采用两级压缩技术,最高输出气体可达21Bar,输出气体压力高,可有效提高汽车空悬系统调节灵敏度;功能集成化,总体积更小。
