The invention provides a hydro-pneumatic suspension system and an engineering vehicle, and relates to the technical field of vehicle suspensions. The hydro-pneumatic suspension system comprises an axle, a hydro-pneumatic spring and a guide mechanism. The hydro-pneumatic spring is connected with the axle; the guide mechanism comprises a first upper thrust rod, a first lower thrust rod, a second upper thrust rod, a second lower thrust rod and a cross beam; the two ends of the first upper thrust rod, the two ends of the first lower thrust rod, the two ends of the second upper thrust rod and the two ends of the second lower thrust rod are hinged to the cross beam and the axle correspondingly, and the first lower thrust rod and the second lower thrust rod are arranged in the front-back direction; the first upper thrust rod and the second upper thrust rod are both obliquely arranged relative to the cross beam, and the extending direction of the first upper thrust rod is opposite to that of the second upper thrust rod. The hydro-pneumatic suspension system is applied to engineering vehicles. The hydro-pneumatic suspension system can reduce left-right shaking of a vehicle to a certain extent so as to improve the stability of the vehicle.
