Abstract

The invention relates to an air suspension and interconnected suspension parallel system. The air suspension and interconnected suspension parallel system at least comprises an interconnected hydraulic system, an air spring system and a control system. An oil cylinder actuator of the interconnected hydraulic system and an air spring of the air spring system are arranged in parallel. The lower end of the oil cylinder actuator and the lower end of the air spring are both connected with wheels, and the upper end of the oil cylinder actuator and the upper end of the air spring are both connected with a vehicle body. The air spring can adjust the height of the vehicle body and the rigidity of the suspension through the control system, and the interconnected hydraulic system can switch the configuration and adjust the damping of the suspension through the control system, so that the function is greatly expanded, and the requirements of the vehicle in different application scenes can be met.

Description

technical field [0001] The present invention relates to the technical field of vehicle suspension, in particular to a parallel system of air suspension and interconnected suspension. Background technique [0002] With the increasing intelligence of automobiles, people put forward higher requirements for the maneuverability, comfort and safety of vehicle chassis. However, because the stiffness, damping and body height of traditional suspension cannot be adjusted, the suspension design always has to compromise between sportiness and comfort. For example, in order to improve the anti-roll ability of the vehicle, a roll bar is often used, but due to the linear torsional stiffness of the roll bar, when one wheel is bumped, the vibration will be transmitted to the other side of the body, resulting in a decrease in comfort. [0003] To improve comfort while improving handling, a passive hydraulically interconnected suspension was proposed. Because the passive hydraulic interconne...
