Abstract

The utility model relates to a vibration-damping rail for trains, in particular to a train rail for steady transition when the train wheels pass through the joint by changing the shape of the rail joint. The upper and bottom joints of the front section of the steel I beam rail are > shaped joints which are convex outward, and the middle joint is a step type joint which is convex toward the center at one side; the upper and bottom joints of the steel I beam rail at the rear section are > shaped joints which is concave inward, and the middle joint is a step type joint which is concave toward the center at one side. The vibration-damping rail has the advantages that joints of different shapes are adopted, which is especially favorable for the train wheels to be transited onto another rail when the train advances, and the pressure from the train carriages is also naturally decomposed; the vibration-damping rail can ensure steady advancing of the train, effectively reduce vibration, and is favorable for speeding up the train. The train rail for steady transition of the utility model is suitable for the improvement on the rails of freight and passenger trains.

Description

A kind of train track of stable transition interface

Technical field

The utility model relates to a kind of train damping steel rail, specifically relates to a kind of the change when track interface shape makes train wheel through interface and can stablize the train track of transition.

Background technology

Existing train rail interface is perpendicular to that train advances or direction of retreat, like this when this interface of train running wheel process, can be because the seam of interface causes vibrations, not only can influence the gait of march of train, also can produce destruction to rail and train wheel, especially when train is run at high speed, destroy particularly evidently, even can lead to a disaster.Although more existing improved plans are not orthogonal to the train running direction as merely the rail joint end direction being changed into, the defective of this scheme is can't rail is fixing more firmly, also is difficult to two one steel rail keeping parallelisms are unfavorable for the train damping simultaneously.

Summary of the invention

The technical problems to be solved in the utility model is at the deficiencies in the prior art, and a kind of train track that two joint rail joint end shapes make the stable transition interface of train track smooth transition that changes is provided.

The train track of a kind of stable transition interface of the utility model is achieved by following technical proposals: the utility model kind is stablized the train track of transition interface, comprise prosthomere i iron track, deutomerite i iron track, described prosthomere i iron track upper interface is the greater-than sign type interface that outwards protrudes, the middle part interface is the stepped ramp type interface to a side central protuberance, and prosthomere i iron track bottom is the greater-than sign type interface that outwards protrudes; Described deutomerite i iron track upper interface is recessed inwards greater-than sign type interface, and the middle part interface is to the recessed stepped ramp type interface in a side center, and bottom interface is recessed inwards greater-than sign type interface.

The train track of a kind of stable transition interface of the utility model has following beneficial effect compared with prior art: the train track of a kind of stable transition interface of the utility model adopts difform interface in i iron track upper, middle, and lower part, seam is initial to be dispersed in the certain distance, be particularly conducive to train when advancing wheel carry out the transition to naturally on another one steel rail, the pressure of railway carriage also obtains natural decomposition; I iron track middle part is that an one steel rail and another one steel rail mesh together, and rail is on sustained height before and after having guaranteed.The train track of a kind of stable transition interface of the utility model can make train advance steadily, effectively reduces vibrations, reduces noise, helps the speed-raising of train.The train track of a kind of stable transition interface of the utility model is applicable to the improvement of lorry, passenger vehicle rail.
