The invention provides an oil-gas balance suspension system capable of lifting an axle. The oil-gas balance suspension system comprises a front axle suspension assembly, a rear axle suspension assembly and a lifting axle control system. The lifting axle control system is in circulation connection with the front axle suspension assembly and the rear axle suspension assembly; the lift bridge control system comprises an energy accumulator and a damper, and the energy accumulator and the damper are in circulation connection. The front axle suspension assembly comprises a front axle and a front hydro-pneumatic spring; the rear axle suspension assembly comprises a rear axle and a rear hydro-pneumatic spring; and the front hydro-pneumatic spring is in circulation connection with the rear hydro-pneumatic spring. An oil-gas type balance suspension structure is adopted, and compared with a traditional steel plate spring, the bearing capacity is large, and the failure rate is low; the hydro-pneumatic spring is variable
