Abstract
A kind of wheel multilamellar antivibrator.The railway network of China constantly expands in recent years, and particularly high-speed railway obtains fast development.Along with the raising of railway speed, the noise problem that train operation is brought becomes increasingly to highlight.Wheel/rail noise is the main noise source in high-speed railway running.A kind of wheel multilamellar antivibrator, its composition includes: installing plate (1), restraint layer (2), pad (4) and damping rubber (3), installing plate, restraint layer, pad and damping rubber composition antivibrator (9), antivibrator is by the dovetail groove being arranged on wheel (8) of bolt (10) even structure in the form of a ring, restraint layer replace with described pad superpose formation sandwich, the upper arcuate end face of sandwich welds with described installing plate, in sandwich, produced space is filled with described damping rubber, damping rubber bonds together with restraint layer.This utility model is applied to wheel damping device.
Description
Technical field:
This utility model relates to a kind of wheel multilamellar antivibrator, uses the principle of dynamic vibration absorber, it is possible to mate simultaneously
Multiple natural frequencies of wheel, are greatly reduced the radial vibration of wheel and overall radiated noise, are uniformly distributed on wheel, its
Quantity is even number, to meet the requirement for dynamic balance in train travelling process.
Background technology:
The railway network of China constantly expands in recent years, and particularly high-speed railway obtains fast development.Along with railway speed
The raising of degree, the noise problem that train operation is brought becomes increasingly to highlight.Wheel/rail noise is that high-speed railway ran
Main noise source in journey.Wheel/rail noise Producing reason is that the factors such as the uneven surface of wheel and track cause
Wheel and the vibration of track, and the vibration of wheel and track will cause noise.The particularly noise of wheel radiation, along with train
The raising of speed becomes more and more obvious.Noise problem has had a strong impact on the orthobiosis of comfortableness by bus and people on the way,
The radiated noise of wheel in train travelling process is reduced it is therefore desirable to take measures.
Traditional sound barrier, as a kind of soundproof measures, also exists costly and affects attractive in appearance and effect is the most aobvious
The shortcomings such as work.Increasing wheel damping and then can preferably solve these problems, therefore world in recent years various places are obtained for soon
The development of speed.Wheel multilamellar antivibrator is based on the high ferro wheel vibration and noise reducing product that such background is developed.
Summary of the invention:
The purpose of this utility model is to provide a kind of wheel multilamellar antivibrator.
Above-mentioned purpose is realized by following technical scheme:
A kind of wheel multilamellar antivibrator, its composition includes: installing plate, restraint layer pad and damping rubber, described peace
Dress plate, described restraint layer pad and described damping rubber composition antivibrator, described antivibrator is tied in the form of a ring by bolt
Structure is arranged in the dovetail groove on wheel uniformly, described restraint layer replace with described pad superpose formation sandwich,
The upper arcuate end face of described sandwich welds with described installing plate, produced empty in described sandwich
Gap is filled with described damping rubber, and described damping rubber bonds together with described restraint layer.
Described wheel multilamellar antivibrator, every layer of steel plate thickness difference of described restraint layer, described pad and institute
The thickness of the damping rubber stated is the most identical.
Described wheel multilamellar antivibrator, described antivibrator is arranged in inside wheel tread, and the institute installed
The antivibrator number stated is even number, and each layer thickness of described antivibrator and the number of plies determine according to natural frequency of wheel, and along circle
The uniform number of circumferential direction changes the most therewith.
Described wheel multilamellar antivibrator, described sandwich and described installing plate offer installing hole one,
The marginal position of described installing plate is provided with installing hole two.
The beneficial effects of the utility model:
1. this utility model novel structure, effect is notable, and dynamic vibration absorber principle is applied to wheel vibration and noise reducing.Pass through
The combination of multiple structure and elastomeric material can mate multiple frequencies of wheel simultaneously.Each restraint layer of this structure has different
Rigidity and quality, can play the effect of damping rubber during unsteadiness of wheels to greatest extent.This antivibrator leads to simultaneously
Cross bolt and be arranged on inside wheel tread, the radial vibration of wheel can be greatly reduced in the case of not affecting traffic safety,
Thus reduce radiated noise.
