Abstract
Wheel synthetic damping ring.Train speed often doubles, and the wheel-rail noise of its radiation will increase by 9 decibels, and simultaneously along with the raising of train speed, the proportion that wheel noise accounts in wheel-rail noise is increasing, it is therefore necessary to take measures to reduce the radiated noise of wheel.Composition of the present utility model includes: synthetic damping ring (1), described synthetic damping ring includes hollow metal ring (2), described hollow metal ring is internally installed hollow rubber ring (3), described hollow rubber ring is internally installed solid metal ring (4), described synthetic damping ring is arranged in the rectangular channel inside wheel (5) wheel rim, and opening part connects with flexible member (6).This utility model is used for wheel synthetic damping ring.
Description
Technical field:
This utility model relates to a kind of wheel synthetic damping ring.
Background technology:
In recent years, high-speed railway is developed rapidly, and it is high with speed, freight volume is big, unit energy consumption is low and safety is relaxed
The characteristic such as suitable is favored by people, but the raising of train running speed will necessarily serve new technological challenge by band, as drawn
Technology, aeromechanics technology, railway technology etc., wherein the vibration and noise reducing of train is one of them major issue.Train
Speed often doubles, and the wheel-rail noise of its radiation will increase by 9 decibels, and simultaneously along with the raising of train speed, wheel noise exists
The proportion accounted in wheel-rail noise is increasing, it is therefore necessary to take measures to reduce the radiated noise of wheel.Existing technology includes
Disc type brake is used to replace Block brake or use composite brake shoe to replace cast iron brake shoe, increase wheel damping and to wheel
Take sound source shielding etc., wherein increase wheel damping be most effective be also most widely used method.
Utility model content:
The purpose of this utility model is to provide a kind of wheel synthetic damping ring.
Above-mentioned purpose is realized by following technical scheme:
A kind of wheel synthetic damping ring, its composition includes: synthetic damping ring, and described synthetic damping ring includes hollow gold
Belonging to ring, described hollow metal ring is internally installed hollow rubber ring, and described hollow rubber ring is internally installed solid metal
Ring, described synthetic damping ring is arranged in the rectangular channel inside wheel rim, and opening part connects with flexible member.
Described wheel synthetic damping ring, described hollow metal ring, described hollow rubber ring, described solid gold
The cross section belonging to ring is rectangle.
Described wheel synthetic damping ring, described hollow rubber ring, described solid metal ring be a domain or
Person is one group of bulk the most evenly distributed.
Described wheel synthetic damping ring, the opening part of described synthetic damping ring is connected by spring, described spring
It is arranged on the bearing pin being connected together with described synthetic damping boxing.
Described wheel synthetic damping ring, the width of rectangular phase inside described synthetic damping ring and wheel rim
With, the rectangular channel degree of depth is the 1/2 of described synthetic damping ring.
The beneficial effects of the utility model:
This utility model solves the wheel caused in high-speed railway running due to wheel track uneven surface equal excitation
Vibration noise problem, according to frictional damping principle, devises a kind of synthetic damping ring that can reduce unsteadiness of wheels noise, works as car
When wheel occurs vibration deformation, there is relative slip between synthetic damping ring and wheel, thus convert vibrational energy into heat energy and dissipate
Send out, simultaneously synthesizing damping ring is internally installed hollow rubber ring (or block rubber) and solid metal ring (or metal derby), metal
The vibration deformation of ring will cause the vibration of elastomeric material, deformation etc., thus consumes vibrational energy further, this synthetic damping ring energy
Enough vibration noises reducing wheel in bigger frequency range, its acting frequency upper limit is more than 6000 Hz, and this synthesis simultaneously hinders
Buddhist nun's ring has the features such as compact conformation.
This utility model compact conformation, deft design；Take full advantage of the space within hollow metal ring, be filled with rubber
And metal；The damping vibration noise with reduction wheel is frictionally produced, simultaneously because close between synthetic damping ring and wheel
Become damping ring to cause the rubber within synthetic damping ring to extrude with unsteadiness of wheels deformation, detrusion etc., also create resistance
Buddhist nun's effect, can reduce the vibration noise of wheel further；Synthetic damping ring is arranged on wheel by the form of rectangular channel,
The flexible members such as synthetic damping ring opening part spring connect, and enormously simplify erector on the premise of guarantee is safe and reliable
Skill, simultaneously because the pretension effect of spring, increases the frictional force between synthetic damping ring and wheel, such that it is able to increase synthesis
The effect of damping ring frictional damping；This synthetic damping ring can provide relatively for wheel in the case of not affecting train operating safety
Good effect of vibration and noise reduction.
