Abstract

The invention provides a novel railway rail joint, which aims at the problems that the prior railway rail joints in China are high in friction and noise, affects train speed, and the like because of plane-to-plane connection. The invention provides the novel railway rail joint, which changes partial rail head (1) of an I-shaped rail in contact with wheels from a plane into two tenon shape joints with one side convex and the other side concave, namely an 'N' shape, and does not change a middle rail web (2) or a bottom (3). When the rail is laid, any two joints are aligned, and a steel plate (5) is placed in the two joints and fixed by screws (4). The joint can also be changed into a miter joints at an angle of 30 to 60 degrees. The railway rail joint can reduce the friction between train wheels and the rail joint, and has the advantages of raising the running speed of trains, reducing train noise and the like.

Example Embodiment

[0013] Below in conjunction with accompanying drawing, invention is described further:
[0014] A new type of railway rail joint, which changes the part of the rail head (1) where the "I"-shaped rail contacts the wheel from a flat surface to two "mortise" shaped joints with half protruding and half recessed, that is, " "The shape of the middle rail waist (2) and the bottom (3) remain unchanged. When laying the rail, align any two joints, put them into the steel plate (5), and fix them with screws (4).
[0015] A new type of railway rail head, which is to change the "I"-shaped rail head (1) in contact with the wheel from a flat surface to a 50° inclined joint. The two ends of the inclined plane are straight lines, and the joint between the straight line and the inclined plane is a straight line. shape, the middle rail waist (2) and the bottom (3) of the rail remain unchanged. For the auxiliary rail, align any two joints, put in the steel plate (5), and fix it with screws (4).
