Fixed frog wheel transmission area wing rail buffering structure
The invention relates to a fixed frog wheel transmission area wing rail buffering structure. By improving point rail and wing rail top face structures, the cross passing smoothness of a train is enhanced, the stress state of a point rail and wing rails is improved, and then the service life of a frog is prolonged by means of the buffering structure. The height of the portions, corresponding to the 35-mm wide portion of the point rail of the frog, of the wing rails is reduced gradually in the follow end direction, and transferred to the height of standard steel rails of the portions, corresponding to the 60-mm wide portion of the point rail, of the wing rails, so that impact on the top faces of the wing rails when the train enter the cross in the forward direction is buffered, the cross passing smoothness of the train is enhanced, the stress state of the point rail and the wing rails is improved, and the service life of the frog is prolonged.
