Description
Technical field
The invention belongs to train wheel noise reduction technology field, more particularly to a kind of composite damping for wheel
Ring.
Background technology
Recently as the construction in city, track public transport has obtained quick development.This is facilitating people's trip
While, a series of problem is also brought, noise pollution is one of them.Due to people's living standards continue to improve,
People are also declining the tolerance of noise.Therefore reducing the noise of Transit Equipment just becomes one of enterprise's care
Problem.For city railway vehicle, wheel-rail noise is the largest one of noise source, and wheel noise is wherein most important
Part.The wheel of most of subway or light rail vehicle is that simple metal is made, the noise after being encouraged by wheel-rail interaction
Radiate bigger.Therefore many technical measures for reducing unsteadiness of wheels noise are come into being.Such as constraint is pasted on wheel web
Damping installs frictional damping ring and using elastic wheel etc. on wheel rim.These methods reduce wheel to a certain extent
Noise, but all there is damping-constraining is pasted in some shortcomings, such as web, there is the danger that damping-constraining comes off；Friction
Damping ring can increase low-frequency noise while overall noise is reduced；Elastic wheel is complicated and cost is higher, and reliability is not yet
Such as metallic wheel.
Invention content
The present invention proposes a kind of for vehicle to solve the vibration noise technical problem in high speed train wheel operational process
The composite damping ring of wheel.The present invention using frictional damping and viscoelastic damping principle, can act on simultaneously train wheel from
Middle low frequency solves the contradiction that can increase low-frequency noise when reducing wheel high-frequency noise, is greatly reduced to the entire frequency range of high frequency
The vibration noise of wheel.
The purpose of the present invention is achieved through the following technical solutions：A kind of composite damping ring for wheel, the compound resistance
Buddhist nun's ring includes outer layer metal 1, viscoelastic layer 2 and solid inner layer metal 3；The cross-sectional shape of the composite damping ring is circle,
The cross section of the outer layer metal 1, viscoelastic layer 2 and solid inner layer metal 3 is concentric circles；1 inside of outer layer metal is superimposed
Viscoelastic layer 2, the 2 inside superposition solid inner layer metal 3 of viscoelastic layer；Notch is provided on the composite damping ring convenient for peace
Dress.
Further, the viscoelastic layer 2 is fixed by the extruding between solid inner layer metal 3 and outer layer metal 1.
Further, the composite damping ring is installed in the semi-circular recesses at 4 wheel rim of wheel, groove diameter with it is compound
It is identical to damp ring diameter.
Further, indentation, there is connected and is fastened by elastic element 5 after the composite damping ring is installed on wheel 4.
Further, the diameter of the elastic element 5 is identical with the composite damping ring diameter.
The composite damping ring structure of the present invention is compact, simple, can efficiently use the structure of existing wheel, not change it
The further reduction of vibration noise is realized in the case of structure.It is with good economic efficiency and real for the transformation of existing line
With value.Simultaneously because the composite damping ring has reserved installation gap, mounting process is very simple, does not need to special equipment.
In addition to this, which solves adjustment of the damping ring to temperature by elastic element well, makes damping ring
Effect of vibration and noise reduction do not change with the variation of the factors such as the pretightning force as caused by temperature.Finally, composite damping ring have compared with
Good safety, due to being installed in the groove of wheel, and the fastening that has elastic component, there is no what is come off suddenly during use
Problem.

Specific embodiment
The technical solution in the embodiment of the present invention is carried out below in conjunction with the attached drawing in the embodiment of the present invention clear, complete
Ground describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.Based on this
Embodiment in invention, the every other reality that those of ordinary skill in the art are obtained without making creative work
Example is applied, shall fall within the protection scope of the present invention.
With reference to Fig. 1-Fig. 2, the present invention proposes a kind of composite damping ring for wheel, and the composite damping ring includes outer layer
Metal 1, viscoelastic layer 2 and solid inner layer metal 3；The cross-sectional shape of the composite damping ring is round, the outer layer metal
1st, the cross section of viscoelastic layer 2 and solid inner layer metal 3 is concentric circles；The 1 inside superposition viscoelastic layer 2 of outer layer metal, institute
State 2 inside superposition solid inner layer metal 3 of viscoelastic layer；The viscoelastic layer 2 is inlayed between the two metal layers, the viscoplasticity
Layer 2 is fixed by the extruding between solid inner layer metal 3 and outer layer metal 1.When double layer of metal is vibrated and is deformed, viscoelastic layer
2 to bear tension and compression shear-deformable, so as to generate viscoelastic damping.Microcosmic phase occurs between outer layer metal 1 and wheel 4 to sliding, from
And generate frictional damping.Composite damping ring has taken into account the characteristic of viscoelastic damping and frictional damping, more existing frictional damping ring
Effect of vibration and noise reduction is more preferable.
With reference to Fig. 3-Fig. 4, the composite damping ring is installed in the semi-circular recesses at 4 wheel rim of wheel, groove diameter with
Composite damping ring diameter is identical to ensure coming into full contact between composite damping ring and wheel 4.It is provided on the composite damping ring
Notch.Indentation, there is connected and is fastened by elastic element 5 after the composite damping ring is installed on wheel 4.To ensure that wheel 4 revolves at a high speed
Dynamic balancing and installation during turning need, and the diameter of elastic element 5 and density etc. are approximate with composite damping ring.It is preferred that the bullet
The diameter of property element 5 is identical with the composite damping ring diameter.
Composite damping ring of the present invention takes into account the characteristic of frictional damping and viscoelastic damping, and it is therefrom low can to reduce wheel
Frequency arrives the vibration noise of high frequency full frequency band.The present invention is applied to the vibration and noise reducing of train wheel.The particularly cities such as subway, light rail
Rail traffic vehicles.Since path limits, this kind of vehicle is easily influenced in the process of running by wheel track horizontal force, from
And generate larger whistler.Traditional frictional damping ring can reduce the whistler of wheel to a certain extent, still
It is found through experiment that the drawbacks of such damping ring while increasing overall noise reduction there is that can increase wheel low-frequency noise, therefore
Devise the composite damping ring.Composite damping ring of the present invention has taken into account the effect of frictional damping and viscoelastic damping.It is multiple
It closes and microcosmic opposite slip occurs between the outer layer metal 1 of damping ring and wheel 4, generate frictional damping；Viscoelastic material layer exists
Occur to squeeze under the action of double layer of metal and shear-deformable, generate viscoelastic damping.Increasing damping ring totality damping
Under the premise of, pass through the low-frequency noise of viscoelastic damping reduction wheel.
It above to a kind of composite damping ring for wheel provided by the present invention, is described in detail, herein should
The principle of the present invention and embodiment are expounded with specific case, the explanation of above example is only intended to help to manage
Solve the method and its core concept of the present invention；Meanwhile for those of ordinary skill in the art, thought according to the present invention,
There will be changes in specific embodiment and application range, in conclusion the content of the present specification should not be construed as to this hair
Bright limitation.
