Abstract
The utility model discloses a noise-damping wheel for railcars. The noise-damping wheel comprises a wheel rim and spokes. The inner side of the wheel rim is provided with a circular groove embedded with a noise-damping ring. The noise-damping ring is made of the metal materials. With the friction of the noise-damping ring and the circular groove, the vibration energy can be absorbed, thereby achieving a goal of lowering the noise. The utility model has the advantages of simple structure, convenient assembly and excellent noise-damping effects.
Description
Technical field
The utility model relates to a kind of wheel of guideway vehicle, particularly a kind of noise reduction wheel with the effect of abating the noise.
Background technology
The noise pollution of guideway vehicle has become the shortcoming of a key of city railway vehicle, also becomes obstacles of its a large amount of development of restriction, and the noise pollution that therefore how to reduce guideway vehicle becomes current important problem.In the noise of guideway vehicle especially the noise between the wheel track in the highest flight, the noise that therefore how to reduce between the wheel track becomes the problem that our times is paid close attention to.But the noise trailing wheel and the rail both direction that reduce between the wheel track are set about, so the noise reduction wheel has just produced.The method of wheel noise reduction has many, have plenty of in wheel, be provided with the elastic colloid of making by High molecular materials such as rubber absorb the vibration and noise, but this structure exists easy loss, short defective of life-span, and High molecular material often has comb. simultaneously, also exists disaster hidden-trouble; The noise-reducing structure of the noise reduction wheel that has is very complicated, and installation and maintenance are all inconvenient, has also increased the manufacturing cost of wheel, and because its complex structure, it is big to occupy the space, causes difficulty for the installation of brake disc.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, easy to assembly and noise reduction wheel with better erasure effect.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of noise reduction wheel, comprise wheel rim and spoke, and the inboard of described wheel rim is provided with circular groove, is inlaid with the noise reduction ring in the circular groove.
A kind of preferred structure is that the circular groove of wheel rim inboard is two, lays respectively at the both sides of spoke.
Above-mentioned noise reduction ring is preferably becket.
Noise reduction wheel of the present utility model has only increased circular groove and noise reduction ring on the basis of common wheel, therefore simple in structure, easy to assembly.Also have the following advantages simultaneously:
● safety: steel loop embeds in the circular groove, without fasteners such as bolts, can not come off.
● adopt becket as the noise reduction ring, no combustible material.
● need not maintenance, be convenient to check.
● good muffling effect, can reduce by 27 decibels in frequency domain.
● the space that takies wheel is little, and brake disc can be installed.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the cutaway view of the utility model noise reduction wheel.
The specific embodiment
Noise reduction wheel of the present utility model as shown in Figure 1, be provided with the twice circular groove in the inboard of wheel rim 1, the twice circular groove lays respectively at the both sides of spoke 2, be inlaid with a noise reduction ring 3 in the per pass circular groove, this noise reduction ring 3 is a becket, noise reduction ring 3 forms interference fit with wheel rim 1 in circular groove, the noise reduction ring is pressed in the circular groove with press device.Other structure is identical with common wheel.
Because the phase mutual friction produces noise, this birdie is difficult to make the people to bear during especially by small curve radius between the common rail wheel wheel track.The noise reduction principle of the utility model wheel is as follows: when wheel is sounded, wheel must vibrate by certain mode, no matter wheel is by that a kind of modal vibration, buckling deformation (lateral deformation) or radial deformation (linear deformation) must take place in wheel, no matter be the sort of shape of shaking, can rub between steel loop and the circular groove, consume its energy, make the very fast decay of vibration, thereby the noise between the wheel track is reduced.Damping when steel loop noise reduction wheel increases unsteadiness of wheels can reduce about 27 decibels of noises than common the wheel when 1125HZ.
