The invention relates to a front axle composite air suspension system matched with a straight thrust rod, and belongs to the technical field of commercial vehicle front axle suspensions. The front axle composite air suspension system comprises a frame assembly which comprises frame longitudinal beams which are parallel to each other and arranged at intervals; a front axle assembly; a steel plate spring which is longitudinally fixed on the front axle assembly so as to elastically support the frame longitudinal beam; a vibration reduction air bag which is fixedly positioned between the front axle assembly and the frame longitudinal beam so as to elastically support the frame longitudinal beam; and a longitudinal inclination prevention assembly which comprises an air bag installation support fixed to the front axle assembly and a fixing support located on the front side of the front axle assembly and perpendicularly connected with the bottom of the longitudinal beam of the frame, wherein a longitudinal straight thrust rod is connected between the air bag installation support and the fixing support. The front axle assembly moves around the connecting point of the straight thrust rod and the front end of the steel plate spring, the movement track of the front axle assembly is properly controlled, and the control stability during vehicle running is improved.
