Abstract
The invention discloses a train damping wheel which comprises a center plate (1), a rim (2) and a hub (3). The train damping wheel is structurally characterized in that circular-ring-shaped inner metal plates (4), sticking elastic damping layers (5) and outer metal plates (6) are sequentially fixed to the two sides of the center plate (1) from inside to outside through a bolt (7). The ring width of the circular-ring-shaped inner metal plates (4), the ring width of the sticking elastic damping layers (5) and the ring width of the outer metal plates (6) are the same, and the inner circumferential faces and the outer circumferential faces of circular rings are not in contact with the wheel. According to the train damping wheel, the vibration of the wheel can be relieved, noise generation is inhibited, noise spreading is inhibited, the noise reduction effect is good, installation is easy, the shape of a wheel body is not changed, and application and popularization are easy.
Description
Technical field
The present invention relates to a kind of train damping wheel, belong to traffic and transport field.
Background technology
Along with the fast development of urban track traffic, wheel-rail noise is the Main Noise Sources of track traffic to environmental concerns.Train wheel track rolling noise is excited Wheel Rail Vibration owing to taking turns the irregularity of track surface and then is produced by air borne.
Wheel-rail noise source is primarily of wheel and rail two large divisions composition.The approach of existing reduction railway wheel noise radiation mainly contains: one is according to Principles of Acoustics, reduces wheel noise by wheel profile optimal design.This kind of method is effective, but due to wheel track excitation more complicated, is subject to a lot of restrictions, and must make significantly shape to existing wheel and change, and its work capacity is large and to apply difficulty very large.Two is additional noise reduction device or materials in car wheel structure, as at wheel web surface spraying damping-constraining etc.The damping material of damper restriction layer is high polymers, its vibration and noise reducing mechanism is: become in district at very narrow glassy state, the modulus of poly-mer significantly reduces, display mechanical damping characteristic, at this moment poly-mer has sufficiently high dissipation factor, absorbing vibrational energy that can be a large amount of, thus the vibration reducing wheel.Damper restriction layer reduces noise by reducing unsteadiness of wheels, but the High Rotation Speed of wheel and the severe environment of complexity easily make the adhered layer between damping-constraining and wheel web easily lose efficacy, peel off, thus the detection just needing human and material resources regular and to wheel surface spraying damping-constraining.
Summary of the invention
The object of this invention is to provide a kind of train damping wheel, this wheel can reduce the vibration of wheel, and restraint speckle produces, and hinders noise transmission, excellent noise reduction effect, and be easy to install, do not change wheel body shape, promotion and implementation are easy.
The present invention realizes the technical scheme that its goal of the invention takes: a kind of damping wheel, comprise former, wheel rim and wheel hub, its constructional feature is: described former both sides are all by the bolt interior metal sheet of clamping rings shape, visco-elastic damping layer and outer metal sheet successively from inside to outside;
Interior metal sheet, the visco-elastic damping layer of described annular arrangement are identical with the ring width of outer metal sheet, and the inner peripheral surface of annulus does not contact with wheel with outer peripheral face.
Compared with prior art, the invention has the beneficial effects as follows:
One, by metal sheet, visco-elastic damping layer is arranged on the both sides of wheel rim, avoid because the High Rotation Speed of wheel and the severe environment of complexity make the adhered layer between damping-constraining and wheel lose efficacy, thus damping-constraining occurs occur from the situation of wheel former sur-face peeling.
Two, the metal sheet of annular arrangement and visco-elastic damping layer are fixed on wheel rim both sides, are covered completely in topmost for wheel radiated noise region, hinder the radiation in noise space towards periphery from propagation path.
Three, the outer peripheral face of circular ring metal plate does not directly contact with wheel with inner peripheral surface, prevents the vibration of rim for automobile wheel directly to pass to the outer metal sheet of damping structure, inhibits noise generation.
Four, the visco-elastic damping layer between two adjacent metal sheets can transferring structure power, when there is vibration in wheel in rolling process, rim for automobile wheel and spoke produce and are out of shape, the metal sheet of visco-elastic damping layer both sides is made to produce relative motion, periodically shearing strain is formed at visco-elastic damping layer, by mechanical energy be heat energy and dissipate vibrational energy, decrease the vibration of wheel, thus the generation of restraint speckle.
Five, of the present invention only on the basis of original solid wheel, add metal sheet and visco-elastic damping layer, material alterations is not occurred to the shape of wheel body and structure, so there is no increase potential safety hazard, and easily promotion and implementation; And after wheel web both sides all add metal sheet and visco-elastic damping layer, the total weight of wheel increases less, impact is increased on train unsprung weight less.
In a word, the present invention can the generation of fundamentally restraint speckle, also can hinder sonic propagation of making an uproar, excellent noise reduction effect.
Further, the inside face of outer metal sheet of the present invention is provided with the outside plate projection of bar shaped, and the inner panel interior metal sheet outer surface between every two outside plate projections being arranged two bar shapeds is protruding.
These projections add the area of contact of metal sheet and visco-elastic damping layer, the relative motion of the metal sheet of both sides more easily causes the periodicity shearing strain of visco-elastic damping layer, thus strengthen the effect that mechanical energy is heat energy and dissipate vibrational energy by visco-elastic damping layer, suppress the vibration of wheel entirety, obviously reduce the vibration noise radiation of wheel.
Further, inner panel projection of the present invention and the protruding outer thoughtful inner circumferential from annulus of outside plate are in distribution from dense to sparse.
The vibration that such design meets analysis of wheel vertical surface reduces feature gradually from wheel rim to wheel hub.
Further, bolt of the present invention nut and be provided with rubber ring between nut and outer metal sheet outer surface.
Like this, outer metal sheet does not directly contact with bolt, reduces the transmission of vibration between bolt and outside plate, hinders noise generation and propagation.
Further, the thickness of interior metal sheet of the present invention and outer metal sheet is 0.5 ~ 2mm, and the thickness of visco-elastic damping layer is 0.5 ~ 1.5mm.
Like this, both ensure that the noise reduction of the intensity of metal sheet, rigidity and visco-elastic damping layer, also excessive burden had not been increased to wheel mass simultaneously.
Below in conjunction with the drawings and specific embodiments, the present invention is described further.
