Abstract

The utility model discloses a combined noise reduction track which is formed by combining a plurality of track plates; a plurality of concave parts are arranged on one track plate; a plurality of convex parts matched with the concave parts are arranged on another track plate; and damping layers are arranged on the concave parts and the convex parts. The utility model has the advantages of close connection, low noise, good cushioning effect and long service life.

Description

The noise reduction combined orbit

Technical field

The utility model belongs to the transportation technology field, relates in particular to a kind of noise reduction combined orbit 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 noise reduction combined orbit is provided, and the utility model connects closely, 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 noise reduction combined orbit, it is characterized in that: described track is combined to form by many track plates, one track plate is provided with a plurality of inner fovea parts, and another connected track plate is provided with a plurality of male part that cooperate with inner fovea part, 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, one track plate is provided with a plurality of inner fovea parts, another connected track plate is provided with a plurality of male part that cooperate with inner fovea part, 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, so just reduced the generation of noise greatly, adopted a plurality of inner fovea parts and a plurality of male part to match, connected tightr.

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 noise reduction combined orbit, track is combined to form by many track plates 1, one track plate is provided with a plurality of inner fovea parts 3, and another connected track plate is provided with a plurality of male part 4 that cooperate with inner fovea part 3, 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 has certain cushioning effect greater than the length of male part 4 in the contact position.Buffer layer 2 is 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.
