The invention discloses a vibration reduction steel rail joint which comprises a vibration reduction joint clamping plate and a steel rail joint clamping plate. The vibration reduction joint clampingplate is arranged on the first side of a steel rail, the steel rail joint clamping plate is arranged on the second side of the steel rail, and the side face, close to the steel rail, of the vibrationreduction joint clamping plate is a first arc face with a preset first arc. The first arc surface is tightly attached to the first side of the steel rail. The middle of a fishplate on the outer side of the steel rail joint is heightened to be higher than the rail surface, so that when a wheel passes through the steel rail joint, the fishplate on the outer side and the steel rail bear rolling of the wheel at the same time, a transition effect on the wheel is achieved, the impact force of the wheel on the steel rail is reduced, and a vibration reduction effect is achieved.

本发明公开了一种减振钢轨接头，包括减振接头夹板、钢轨接头夹板，所述减振接头夹板设置在钢轨的第一侧，所述钢轨接头夹板设置在钢轨的第二侧，所述减振接头夹板靠近钢轨的侧面为具有预设的第一弧线的第一弧面，所述第一弧面紧贴钢轨的第一侧。本发明还将钢轨接头外侧鱼尾板中部加高到高于轨面，使车轮在通过钢轨接头时，外侧鱼尾板和钢轨同时承受车轮的碾压，对车轮起到过渡作用，减小车轮对钢轨的冲击力，起到减振的作用。
