Hydraulic active suspension system

The invention provides a hydraulic active suspension system comprising an oil storage module comprising an oil storage tank for storing suspension oil; the balance module is connected with the oil storage module through an oil supply main path; the four hydraulic branches are connected with the balance module, and the balance module is used for balancing oil pressure of the four hydraulic branches; the redundant branch is communicated with the oil storage module and connected with the balance module in parallel, suspension oil and redundant oil are contained in the redundant branch, the oil storage module provides first oil pressure for the balance module through the suspension oil, and the oil storage module provides second oil pressure for the redundant branch through the suspension oil; the redundant branch converts the second oil pressure of the suspension oil liquid into redundant oil pressure of redundant oil liquid. Through the suspension oil in the oil storage module of the active suspension system, a
