Abstract
The utility model discloses a combined noise reduction track which is formed by combing a plurality of track plates. The track plates are concavely and convexly matched and connected; and damping layers are arranged on a concave part and a convex part. The utility model has the advantages of low noise, good cushioning effect and long service life.
Description
Technical field
The utility model belongs to the transportation technology field, relates in particular to a kind of combined type noise reduction track that reduces the rail train of noise.
Background technology
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 bigger vibrations and produce very big noise when driving to these joints, and this not only makes the passenger be fed up with, especially night, influence the passenger and have a rest, bring adverse effect also for the application life of train and end of rail, shortened the application life of rail.Along with the continuous speed-raising of train, the raising of train speed and the wheel-rail noise that causes is in rising trend, wheel-rail noise is the main sound source of train when the following speed of 250km/h is travelled.
The utility model content
The purpose of this utility model is to overcome the above-mentioned technical problem that existing track exists, and a kind of combined type noise reduction track is provided, and the utility model can reduce noise, has cushioning effect, improves the application life of track.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of combined type noise reduction track is characterized in that: described track is combined to form by many track plates, and track plate and the track plate is concavo-convex is connected is provided with buffer layer on inner fovea part and the male part.
The degree of depth of described inner fovea part is greater than the length of male part.
Described buffer layer is the flexiplast buffer layer.
The employing the beneficial effects of the utility model are:
One, the utility model track is combined to form by many track plates, track plate and the track plate is concavo-convex is connected, and 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.
Two, the utility model also comprises buffer layer, and buffer layer is arranged on inner fovea part and the male part, the noise that has produced because of vibrations when further having reduced train driving.
Three, the degree of depth of the utility model inner fovea part has certain cushioning effect greater than the length of male part, and the effect that reduces noise is more obvious, and the application life of having improved track.

The specific embodiment
A kind of combined type noise reduction track, track is combined to form by many track plates 1, and track plate and the track plate is concavo-convex is connected is provided with buffer layer 2 on inner fovea part 3 and the male part 4.
In the utility model, the degree of depth of inner fovea part 3 makes the contact position have certain cushioning effect greater than the length of male part 4.Buffer layer 2 can be the flexiplast buffer layer.In the junction of track plate and track plate, inner fovea part 3 and male part 4 cooperate butt joint for male and female.
Above-described only is preferred implementation of the present utility model.Should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model principle; need not the technical characterictic that the process creative work just can be associated; can also make some modification and improvement; these variations obviously all should be considered as equivalent feature, still belong within the protection domain of the utility model patent.
