The invention relates to an oil-gas interconnection suspension with self-adaptive damping and adjustable roll stiffness, which comprises at least four hydraulic cylinders and two hydraulic loops, the hydraulic cylinders are respectively positioned at four corners of a suspension system, each hydraulic cylinder comprises an upper chamber and a lower chamber, and the upper chamber and the lower chamber are separated by a piston; the first hydraulic loop is formed by communicating a lower cavity of a left front hydraulic cylinder of the suspension, an upper cavity of a right front hydraulic cylinder, a lower cavity of a left rear hydraulic cylinder and an upper cavity of a right rear hydraulic cylinder through pipelines; the second hydraulic loop is formed by communicating an upper cavity of a left front hydraulic cylinder of the suspension, a lower cavity of a right front hydraulic cylinder, an upper cavity of a left rear hydraulic cylinder and a lower cavity of a right rear hydraulic cylinder through pipelines; the first hydraulic loop and the second hydraulic loop are each provided with an energy accumulator and a control valve, and therefore the functions of being capable of adjusting the roll stiffness and self-adaptive damping are achieved. The control stability and smoothness of the vehicle can be improved, the satisfactory damping effect can be achieved by using a small number of control valves, and therefore the control valve has the advantages of being simple in structure and low in cost.
本发明涉及一种具有自适应阻尼和可调节侧倾刚度的油气互联悬架,包括至少四个分别位于悬架系统四角的液压缸及两个液压回路,每个液压缸均包括上腔室和下腔室,且上腔室与下腔室之间通过活塞隔开;第一液压回路由悬架左前液压缸的下腔、右前的液压缸上腔、左后液压缸的下腔、右后液压缸的上腔通过管路连通构成;第二液压回路由悬架左前液压缸的上腔、右前的液压缸下腔、左后液压缸的上腔、右后液压缸的下腔通过管路连通构成;第一液压回路和第二液压回路上均设有蓄能器及控制阀,从而实现可调节侧倾刚度与自适应阻尼的功能。本发明可以提高车辆的操纵稳定性和平顺性,且使用较少数量的控制阀即可达到满意的减震效果,因此具有结构简单、成本低的优势。
