The invention discloses a negative pressure type automobile suspension system, which comprises a negative-pressure air cylinder, a piston, a connecting rod, an electric lock catch, a pressure reducingrod, a piston, a hydraulic cylinder, a flow guide pipe, an electromagnetic valve, a hydraulic lifting rod, an axle and wheels, wherein inward pressure generated by atmospheric pressure on the pistonin the negative-pressure air cylinder is utilized, the connecting rod pushes the piston to compress hydraulic oil in the hydraulic cylinder, and the hydraulic oil is injected into the hydraulic lifting rod through the flow guide pipe to jack an 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, the pressure in the hydraulic cylinder is not changed, so that the automobile body is kept stable. The electromagnetic valve reduces the flow of the hydraulic oil in the flow guide pipe when the automobile body falls, so that potential energy generated when the automobile body falls is absorbed. According to the negative pressure type automobile suspension system, an automobile body is stable, and the comfort of an automobile is enhanced.

    本发明公开了一种负压式汽车悬挂系统,包括负压气缸、活塞、连接杆、电动锁扣、降压杆、活塞、液压缸、导流管、电磁阀、液压升降杆、车轴、车轮,利用大气压强在负压气缸中对活塞制造的向内压力,经连接杆推动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。
