The invention discloses a negative pressure automobile suspension system. The system comprises a negative pressure cylinder, a piston, a pulley, a steel wire rope, a steel wire rope reel, a connectingshaft, a continuously variable transmission, a chain, a continuously variable transmission, a connecting shaft, a gear, a rack, a piston, a hydraulic cylinder, a flow guide pipe, a solenoid valve, ahydraulic lifting rod, a wheel axle and wheels. Inward pressure generated by atmospheric pressure on the piston in the negative pressure cylinder is utilized, the steel wire rope reel is pulled by thesteel wire rope to be converted into connecting shaft torsion, the connecting shaft torsion is modulated into torsion matched with the weight of an automobile body through the continuously variable transmission, the rack and the piston are pushed by the connecting shaft gear to compress hydraulic oil in the hydraulic cylinder, and the hydraulic oil is injected into a hydraulic lifting rod througha flow guide pipe to jack the automobile body. When the wheel axle moves up and down relative to the automobile body and the hydraulic lifting rod stretches out and draws back, pressure in the hydraulic cylinder is not changed, and therefore the automobile body is kept stable. The solenoid valve reduces the flow of hydraulic oil in the flow guide pipe when the automobile body falls, and thereforepotential energy generated when the automobile body falls is absorbed. According to the negative pressure automobile suspension system, an automobile body is stable, and the comfort of an automobileis enhanced.

    本发明公开了一种负压汽车悬挂系统,包括负压气缸、活塞、滑轮、钢丝绳、钢丝绳卷轮、连接轴、无级变速器、链条、无极变速器、连接轴、齿轮、齿条、活塞,液压缸,导流管,电磁阀,液压升降杆,车轮轴,车轮,利用大气压强在负压气缸中对活塞制造的向内压力,经钢丝绳拉动钢丝绳卷轮转为连接轴扭力,经无级变速器调制为与车身重量相配的扭力,经连接轴齿轮推动齿条与活塞压缩液压缸中的液压油,经导流管注入液压升降杆使车身顶起。车轮车轮轴相对于车身上下移动液压升降杆伸缩时,液压缸内的压力不变,从而使车身保持平稳。电磁阀在车身下落时缩小导流管内液压油流通量,从而吸收车身下落时的势能。本负压汽车悬挂系统使车身平稳,增强车辆的舒适性。
