Free-film type anti-inclination air spring

Abstract

The invention provides a free-film type anti-inclination air spring, which belongs to the technical field of air springs. A transverse stopping gap and a vertical stopping gap exist in the air spring, so that the vibration impact during operation can not be well reduced. In the invention, a lengthened cylindrical pin is adopted, a friction block is arranged, and meanwhile, the concave design for a stopping seat is carried out, and the upper wall of the stopping seat is heightened, so that the design not only can be used for providing a reasonable free gap for the air spring, but also can be used for effectively preventing the phenomenon that the cylindrical pin jumps out of the stopping seat from occurring; and in addition, the air spring is provided with an anti-leveling anti-inclination rubber block, so that the phenomenon that the air spring is inclined can be effectively prevented, and a horizontal elastic gap is realized by the rubber block together with a transverse limiting device. The free-film type anti-inclination air spring is mainly used for a damping system of a magnetic-suspension vehicle.

Description

technical field [0001] The invention belongs to the technical field of air springs, in particular to a free-membrane air spring. Background technique [0002] The spring suspension device is one of the important factors that determine the running quality of the vehicle. To ensure that the vehicle has a good running quality, it must first be considered that the spring suspension device can make the natural frequency of the vehicle's sprung mass low enough. That is to say, the most important measure to improve the running stability of the vehicle is to increase the static deflection of the spring suspension device as much as possible. With ordinary steel springs, the difference between the static deflection at no load and the static deflection at full load can be significant for vehicles with very soft spring suspension. When this difference reaches a large value, it may cause a large difference in the running quality of the vehicle under the maximum load and the minimum loa...

AI Technical Summary

Problems solved by technology

[0004] 1. The height of the stop wall of the air spring is insufficient. When the cylindrical pin of the air spring jumps, the cylindrical pin easily jumps out of the stop seat and loses the shock absorption of the air spring.

The length of the existing air spring cylindrical pin is only 20mm. In the actual application process, due to the irregularity of vehicle vibration, the air spring cylindrical pin is easy to jump out of the stop, and the jumping phenomenon has occurred several times in the actual application process.

[0005] 2. The horizontal stop gap and vertical stop gap of the air spring are insufficient, which cannot well reduce the vibration impact during operation and reduce the running quality of the maglev train;

[0006] 3. Due to the existence of horizontal gaps, the air spring is prone to dumping during installation, which is not conducive to installation, the air spring is seriously biased, and the lateral positioning stiffness is small

[0008] 4. When the air spring is subjected to lateral force, the air spring will be tilted, which will affect the operating quality of the maglev vehicle, and also cause the air spring airbag to be easily damaged and leak, threatening driving safety.
