Abstract
The utility model discloses a tooth-shaped end opening type rail. The utility model relates to the improvement of the tram train rail. The utility model has the structure that the end opening of the rail is changed into the tooth-shaped end opening; the interface of each rail is a staggered match butt joint structure. The utility model has the advantage that by using the track of the end opening, because the interface of the track is not a linear break joint, the train gradually passes through when the train drives to the interface, and thus, the generation of the noise is reduced.
Description
The utility model belongs to the transportation technology field, relates to a kind of improvement of rail train rail.
At present, the track port of rail train is square butt joint, because the temperature difference that weather brings makes track must reserve the shrinkage joint when laying, and train will form vibrations and produce very big noise when driving to these joints.
The purpose of this utility model provides a kind of profile of tooth port type track that reduces noise.
The technical solution of the utility model is as follows:
Change the port of track into the profile of tooth port, each rail joints is the staggered docking structure that cooperates.
The utility model has the advantages that: adopt the track of this port, because of the interface of track is not the straight line breaking joint, train is to be fade-in to cross when driving to interface, has so just reduced the generation of noise greatly.
Fig. 1 is a structure chart of the present utility model;
Wherein: the 1st, track, the 2nd, profile of tooth port;
As can be seen from Figure, in the junction of track and track, port interface is that the male and female cooperation is right Connect.
Claims (1)
1, a kind of profile of tooth port type track is made up of track (1), it is characterized in that: change the port of track (1) into profile of tooth port (2), each rail joints is the staggered docking structure that cooperates.
