The invention provides a novel double-cavity undercarriage buffer device, and belongs to the technical field of undercarriage buffer design, an oil injection and inflation nozzle of a buffer is installed at the left end of the upper portion of a first outer cylinder, and an upper anti-torsion arm is hinged to the lower portion of the first outer cylinder; the lower anti-torsion arm is hinged to the inner cylinder, and the airplane wheel is connected to the right end below the inner cylinder; the supporting ring is mounted on the inner cylinder to form an inner cylinder assembly; the valve is placed in the damping plate, the third nut is in threaded connection with an inner threaded hole of the damping plate, and the damping plate is in threaded connection with the lower end of the oil needle to form an oil needle assembly; the oil needle assembly is installed in the inner cylinder assembly and installed in the first outer cylinder together with the inner cylinder assembly, the upper end is connected with the first outer cylinder, and the lower end fixes the supporting ring and the first outer cylinder through a connecting piece. The piston is arranged in the second outer cylinder; the high-pressure cavity structure and the low-pressure cavity structure are relatively independent, and design is facilitated; the landing load process is relatively smooth, and the maximum load is lower; the position coordination difficulty of the undercarriage and the high-pressure cavity can be reduced according to the arrangement of the fuselage mounting position.
