Abstract：In response to the difficulty in achieving adaptability and smoothness to complex road conditions in mining areas in the existing control form of the suspension system structure of heavy-duty hydraulic vehicles,the uneven distribution of load of vehicles under extreme operating conditions on complex roads is analyzed.Based on the working environment conditions of a certain mining area,the technical design requirements for the proposed hydraulic suspension system are proposed,and the principle of the designed suspension system is explained;By conducting force research on the suspension oil cylinder and the entire vehicle under three extreme working conditions of full load climbing,downhill,and unloaded downhill under different connection modes,the optimal connection scheme of the suspension oil cylinder under different working conditions is determined.At the same time,the adhesion of the entire vehicle is checked,and the required driving pressure of the hydraulic system is calculated;Finally,the parameters of the hydraulic suspension system are calculated and matched,to provide strong support for the feasibility of the product system scheme.
