Abstract

The invention relates to damping and buffering equipment for a high-speed railway, in particular to a rubber air spring for a high-speed railway, comprising a supporting seat, a rubber capsule, a rubber surface, a cover plate and a throttling hole. The rubber air spring is characterized by comprising the supporting seat, the rubber capsule, the rubber surface, the cover plate and the throttling hole, wherein the bottom of the rubber capsule is fixedly provided with the supporting seat; the cover plate is fixed on the top of the rubber capsule; the surface of the inner wall of the rubber capsule is provided with a rubber ribbed band; the lower surface of the supporting seat and the upper surface of the cover plate are respectively provided with a screw steel pipe locating pin; and the throttling hole is arranged in the upper part of the rubber capsule. Due to the adoption of the ribbed band arranged on the surface of the inner wall of the capsule of the rubber air spring provided by the invention, the fatigue resistance of the spring is effectively enhanced, and the service life of the spring is prolonged; and due to the adoption of the throttling hole arranged in the spring, vibration in the spring using process can be attenuated, the spring is enabled to keep lower and approximately equal vibration frequency, and meanwhile, the service life of the spring is prolonged.

Description

technical field [0001] The invention relates to a shock absorbing and buffering device for high-speed rail, in particular to a rubber air spring for high-speed rail. Background technique [0002] With the rapid development of economy and society, the accelerated pace of life, the connection between cities has become closer and closer, and people have higher and higher requirements for travel efficiency. The emergence of high-speed rail meets this demand in time. In the prior art, the rubber air spring used with the bogie of the high-speed rail has a large impact due to the high-speed rail running, and the fatigue resistance performance needs to be improved. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a rubber air spring for high-speed rail with simple, ingenious and reasonable structure. The rubber air spring for high-speed rail has obvious shock absorption effect and long service life...
