A rubber shock absorber for trains with reduced rubber deformation

Abstract

The invention relates to the technical field of rubber dampers for a train, and discloses a rubber damper for the train for reducing rubber deformation. The rubber damper comprises a rubber body. A spring rod is movably connected with the surface of the rubber body. Connecting rods are slidingly connected with the positions, located at the two ends of the spring rod, in the rubber body correspondingly. A hollow channel is fixedly connected with the surface of each connecting rod. The surface of each hollow channel is fixedly connected with a supporting plate. The surface of the side, away fromthe corresponding hollow channel, of each connecting rod is provided with a slide rail. The surface of each slide rail is slidingly connected with a driving rod. The spring rod drives the connectingrods at the two ends of the spring rod to slide close to each other on the surfaces of the slide grooves and squeeze the driving rods to slide on the surfaces of the slide rails, the driving rods aresqueezed to drive springs on the lower side to get close to each other, a filling ball is squeezed to release gas when the springs get close to each other, the gas flows into the hollow channels through a gas flow pipe and is then discharged out of air holes in the surfaces of the supporting plates, and therefore the effect of resisting the shrinkage deformation of the rubber body through internalinflation is realized.

Description

technical field [0001] The invention relates to the technical field of rubber shock absorbers for trains, in particular to a rubber shock absorber for trains that reduces rubber deformation. Background technique [0002] As an important type of shock absorber, rubber shock absorbers have been widely used in various types of machinery, automobiles, railway locomotives, water vehicles, airplanes and other aircraft; their excellent performance is widely used in train tracks. [0003] The reason why the rubber shock absorber is widely used is that it has durable high elasticity, and has excellent functions of vibration isolation, impact isolation and sound insulation, but its essence is rubber, and rubber is susceptible to temperature, oil, ozone, sunlight, etc. And chemical solvent corrosion, the function is easy to age and relax, so the service life is short. [0004] Among them, the temperature has the greatest influence on the rubber shock absorber. It is well known that th...

[0004] Among them, the temperature has the greatest influence on the rubber shock absorber. It is well known that the rubber shock absorber is related to the hardness of the rubber. Influence, that is, the temperature is high, the rubber softens and deforms, and the hardness decreases, and vice versa, and the traditional rubber shock absorber does not have a special treatment method for this, resulting in the shock absorption effect of the rubber shock absorber inconsistent with the expectation. Therefore, a rubber shock absorber for trains that reduces rubber deformation came into being
