Double-layer elastic base plate and rail fastener
The invention discloses a double-layer elastic base plate and a rail fastener. The double-layer elastic base plate comprises a first elastic base plate, and a second elastic base plate. The first elastic base plate is fixedly arranged at the upper part of an iron base plate of a fastener; the second elastic base plate is arranged at the lower part of the iron base plate of the fastener; at least one groove is formed in the upper surface and/or the lower surface of the first elastic base plate. According to the double-layer elastic base plate combined structure of a railway fastener, enough elasticity of the fastener is guaranteed, the damping performance of the fastener is improved, the durability, weather resistance and wear resistance of the elastic base plate of the fastener are guaranteed, the service life of the fastener is prolonged, and the wheel rail vibration source intensity is reduced.
本发明公开了一种双层弹性垫板及轨道扣件，包括第一弹性垫板；第二弹性垫板；所述第一弹性垫板固设在扣件的铁垫板的上部；所述第二弹性垫板设置在扣件的铁垫板的下部；所述第一弹性垫板的上表面和/或下表面上设置有至少一个沟槽。本发明通过提供铁路扣件双层弹性垫板组合结构，保证扣件足够的弹性，提高扣件阻尼性能，同时保证扣件弹性垫板的耐久性、耐候性以及耐磨性能，提高扣件使用寿命，降低轮轨振动源强。
