Description
Technical field
The invention belongs to train wheel noise reduction technology field, rubs and hinders more particularly to a kind of multilayer for wheel
Buddhist nun's device.
Background technology
Also the problem of some are negative is brought while the development of high-speed railway brings convenient.Vibration noise is exactly
One of them.Excessive vibration noise level had not only influenced the ride comfort of passenger but also can influence the normal life of resident on the way.
Therefore the vibration noise for the reduction high-speed railway that takes measures becomes an important topic of the development with high-speed railway.With
The raising of train speed, the noise problem of wheel increase faster compared to wheel rail system other parts, it is therefore necessary to take and arrange
Applying reduces the vibration noise of wheel.Increase wheel damping be reduce that unsteadiness of wheels noise is most economical and effective method it
One, occur many products related to this both at home and abroad.
The content of the invention
The present invention proposes that one kind is used for car to solve the vibration noise technical problem in high speed train wheel operational process
The multilayer frcition damper of wheel.The multilayer frcition damper uses the principle of frictional damping, considerably increases each mode of wheel
Damping ratio, the effect of frictional damping has been given full play to using sandwich construction.
The purpose of the present invention is achieved through the following technical solutions：A kind of multilayer frcition damper for wheel is described more
Layer frcition damper includes installing plate 1 and multilayer friction plate 2, and the multilayer friction plate 2 is superimposed on the installing plate 1；It is described more
Multiple mounting holes 3 are provided with layer frcition damper, the both ends of the installing plate 1 are respectively arranged with installation stomidium 4；The multilayer is rubbed
Damper semicircular in shape is wiped, its radius determines that its width is by between the wheel rim and web of wheel 6 according to tread diameter in wheel 6
Space determine.
Further, the multilayer frcition damper is symmetrically mounted in wheel 6 dovetail groove 8 on tread by bolt 7
In.
Further, the multiple mounting hole 3 is 3 mounting holes 3.
Further, the number of plies of the multilayer friction plate 2 increases or reduces according to being actually needed.
Multilayer frcition damper of the present invention takes full advantage of the principle of frictional damping, compared to the frictional damping of individual layer
Ring, the sandwich construction of the multilayer frcition damper are capable of providing the damping of bigger.And relative to the damping using viscoelastic material
For device, which has preferable environmental suitability.Its damping is varied less with environment, Neng Gougeng
Good uses in intercity line.Multilayer frcition damper processing at the same time and installation are all very simple, so as to the more day of one's doom
The consumption of the resources such as the reduction manpower and materials of degree.
Brief description of the drawings
Fig. 1 is the structure diagram of multilayer frcition damper of the present invention；
Fig. 2 is the schematic diagram that multilayer frcition damper is installed on wheel；
Fig. 3 is the partial enlarged view that multilayer frcition damper is installed on wheel.
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, belongs to the scope of protection of the invention.
The damper that the present invention is used to reduce unsteadiness of wheels noise is made of an installing plate 1 and multilayer friction plate 2, also may be used
The quantity of friction plate 2 is increased or decreased according to actual needs such as mass ratio.Friction plate 2 and installing plate 1 are pacified after being superimposed with bolt 7
On wheel 6.When vibration and deformation occurring in wheel operational process, between installing plate 1 and wheel 6, friction plate 2 and installing plate
Relative motion occurs between 1 and between friction plate 2 so as to phase mutual friction consumed energy.
With reference to Fig. 1-Fig. 3, the present invention proposes a kind of multilayer frcition damper for wheel, the multilayer frcition damper
Including installing plate 1 and multilayer friction plate 2, the thickness between installing plate 1 and friction plate 2, and each layer friction plate 2 can be identical
Can be different；The multilayer friction plate 2 is superimposed on the installing plate 1；The number of plies of the multilayer friction plate 2 increases according to actual needs
Add or reduce, be preferably 2 layers.Multiple mounting holes 3, the both ends point of the installing plate 1 are provided with the multilayer frcition damper
Installation stomidium 4 is not provided with；The multilayer frcition damper is pacified using bolt by the mounting hole 3 and the installation stomidium 4
On wheel 6；Multilayer frcition damper is using the form being arranged symmetrically, to ensure that wheel 6 is dynamic flat during operation
Weighing apparatus.The installation of multilayer frcition damper uses the quantity of bolt 7 to be determined according to emulation and experimental result.The pretightning force of bolt 7 is same
Sample needs to determine to reach optimal effect of vibration and noise reduction by testing and emulating.The multilayer frcition damper is in semicircle
Shape, its radius determine that its width is determined by the space between the wheel rim and web of wheel 6 according to tread diameter in wheel 6.
Dovetail groove 8 is provided with wheel 6, the multilayer frcition damper is symmetrically mounted in wheel 6 on tread by bolt 7
Dovetail groove 8 in.
The multiple mounting hole 3 is 3 mounting holes 3.
The both ends of installing plate 1 are fixed on wheel 6, and the both ends of friction plate 2 are then in free state, so equally can
Preferably play the effect of vibration and noise reduction of multilayer frcition damper.When wheel is subject to external drive to shake during operation
When dynamic and deformation, multilayer frcition damper equally can be vibrated and deformed, so multilayer frcition damper and wheel 6 it
Between, and relative motion can occur between multilayer frcition damper inner layers friction plate and rub, so as to consume wheel
Vibrational energy, and then reduce wheel vibration and radiation noise.
The present invention has the features such as novelty simple in structure, excellent noise reduction effect, good environmental adaptability.
Above to a kind of multilayer frcition damper for wheel provided by the present invention, it is described in detail, herein
In apply specific case the principle of the present invention and embodiment be set forth, the explanation of above example is only intended to side
Assistant solves the method and its core concept of the present invention；Meanwhile for those of ordinary skill in the art, the think of according to the present invention
Think, in specific embodiments and applications there will be changes, in conclusion this specification content should not be construed as pair
The limitation of the present invention.
