The invention discloses an air spring for a railway passenger vehicle and a production method of the air spring. The air spring comprises an upper cover plate assembly, an air bag, a rubber seat, an auxiliary spring assembly and a throttling flange which is located in the middle of the rubber seat and connected with the rubber seat, wherein the rubber seat is mounted above the auxiliary spring assembly; the air bag is located above the rubber seat, and the upper cover plate assembly is located above the air bag; the upper cover plate assembly comprises an upper cover plate flat plate, an upper cover plate locating pin, upper cover plate vulcanized rubber, upper cover plate sealing rubber and an upper cover plate support plate connected to the lower side of the upper cover plate flat plate. The production method of the air spring for the railway passenger vehicle comprises the following steps: producing the upper cover plate assembly; producing the air bag; producing the rubber seat; producing the auxiliary spring assembly; assembling the components to form the air spring for the railway passenger vehicle. The air spring can provide high bearing capacity under the condition of smaller mounting height and provide proper vertical and horizontal stiffness values. The air spring manufacturing process control capacity is improved, and the manufacturing cost of the air spring is reduced.
