Abstract

The invention discloses a hydraulic interconnection suspension system. Four hydraulic cylinders, two energy storages, two spherical valves and hydraulic pipes are connected with one another to form two hydraulic branches of the hydraulic interconnection suspension system. The invention further provides an exhausting and sealing method for the hydraulic interconnection suspension system. The hydraulic interconnection suspension system and the exhausting and sealing method have the advantage that bubbles are prevented in the hydraulic branches when the hydraulic interconnection suspension system is used.

Description

technical field [0001] The invention relates to a hydraulic interconnection suspension system. Background technique [0002] The hydraulically interconnected suspension system is composed of two hydraulic branches connected by four hydraulic cylinders, two accumulators, two spherical valves and hydraulic pipes. The normal operation of the hydraulic interconnected suspension system requires that the two hydraulic branches reach the same working pressure and the system must not contain air bubbles. However, the air in the general hydraulic cylinder can only be discharged through the inlet and outlet ports, so it is not easy to discharge the air in the hydraulic cylinder. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hydraulically interconnected suspension system in which air bubbles do not appear in the hydraulic branch circuit during use. [0004] In order to solve the above technical problems, the technical...
