The invention discloses a negative pressure vehicle suspension system. The system comprises a negative-pressure air cylinder, a piston, a piston rod, a hydraulic cylinder, an electromagnetic valve, ahydraulic oil flow guide pipe, an electromagnetic valve, an electromagnetic flow limiting valve, a hydraulic lifting rod, a wheel shaft and wheels. The electromagnetic valve can prevent hydraulic oilfrom entering the hydraulic cylinder to increase pressure borne by the hydraulic oil and be matched with larger vehicle body weight, and the piston rod extrudes the hydraulic oil under the pressure ofa negative-pressure air cylinder piston. The piston in the negative pressure cylinder moves to keep the pressure of the hydraulic oil unchanged so that the vehicle body is in a proper balance state;and when a vehicle encounters an obstacle in a running process, the wheels move upwards to compress the hydraulic lifting rod, the hydraulic oil enters the hydraulic cylinder, the piston rod and the piston are pushed to move outwards, the vehicle body is in a relatively static state, and after the vehicle body crosses the obstacle, the piston in the negative-pressure cylinder moves inwards to pushthe piston rod to push the hydraulic oil into the hydraulic lifting rod. The electromagnetic flow limiting valve is used for absorbing potential energy generated when the vehicle body falls down. Bymeans of the negative-pressure vehicle suspension system, the vehicle body is stable, and the comfort of the vehicle is 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,活塞杆,液压缸,电磁阀,液压油导流管,电磁阀,电磁限流阀,液压升降杆,车轮轴,车轮,所述电磁阀可阻断液压油进入液压缸,以增加液压油所受压力,匹配更大的车身重量,所述活塞杆受负压气缸活塞压力挤压液压油。负压气缸中活塞的移动使液压油压力不变使车身处于合适的平衡状态,当车辆行驶途中遇到障碍物,车轮上行压缩液压升降杆,液压油进入液压缸,推动活塞杆与活塞向外移动,使车身处于相对静止状态,越过障碍后,负压气缸中的活塞向内移动,推动活塞杆将液压油推入液压升降杆。电磁限流阀的使用能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。
