SUSPENSION SYSTEM, CONNECTION/DISCONNECTION CONTROL SYSTEM AND DETECTION METHOD THEREFOR

摘要

A suspension grouping valve set of a multi-bridge suspension system, a suspension system and a detection method therefor. The suspension grouping valve set comprises two hydraulic control one-way valves (11, 12) communicating with an oil pipeline (10) of a hydraulic system and provided with opposing oil inlets; a pressure sensor (4) located on the oil pipeline (10) between the oil inlets of the two hydraulic control one-way valves (11, 12), and used for acquiring pressure information about the oil fluid in the pipeline between the oil inlets of the two hydraulic control one-way valves (11, 12);a control valve set used for simultaneously controlling the opening or closing of the two hydraulic control one-way valves (11, 12); an air control device (7) used for controlling the opening or closing of the control valve set;and a controller which is connected by signals to the pressure sensor (4), controls the action of the air control device (7) and judges whether the oil pipeline (10) of the hydraulic system is connected or disconnected according to the pressure information acquired by the pressure sensor (4).
