An air storage type axle with an upward drainage function comprises a hollow tubular axle head, an axle body and a braking system, wherein the section of the axle body is square; an air inlet port and an air outlet port are formed in the axle body; the air storage type axle is characterized in that a water drain hole is formed above the axle body; a water collecting groove is formed in the inner wall of the axle body right against the downside of the water drain hole; a water drain pipe is mounted in the water drain hole; the bottom end of the water drain pipe penetrates deeply into the water collecting groove; a water inlet or a water inlet gap is formed in the wall of the water drain pipe which penetrates deeply into the water collecting groove; the upper end of the water drain pipe is connected with a water drain valve; and a sealing component is arranged on the inner wall of the axle head. The invention is advantaged in that an air storage tank on an automobile can be eliminated by using the axle as the air storage tank so that the cost is reduced and the weight of an automobile body is also reduced; as the water drain pipe is positioned on the upside and provided with the valve, automatic drainage can be achieved; it is convenient to drain water; collisions of ground and flying stones on the valve can be avoided; the service life of the valve is greatly prolonged; and the air storage type axle is safe and reliable. The invention is also advantaged in that the concept of the air storage type axle is skillful, the structure of the air storage type axle is novel, various hidden troubles and inconvenience brought by putting a water drain port on the downside are solved and the air storage type axle can be widely applied to various hollow automobile axles.
