Abstract
The utility model relates to a wheel noise reduction damping ring. The railway environment noise can be reduced in the following three ways: the first way is to arrange sound-proof walls along railway lines additionally , which has the disadvantage of high investment cost; the second way is to transform the foundation of rails and road beds, which has the defect of high cost and long period, and in inconvenient to construction; and the third way is to adopt noise and vibration reduction measures on wheels, which is not suitable for all kinds of wheels because the prior products are limited. The wheel noise reduction damping ring comprises a ring body (1); a notch is formed on the ring body; an elastic connector (2) is mounted at the notch; and connection holes (3) are formed at the ends of the ring body. The wheel noise reduction damping ring is applied to a train noise reduction device.
Description
Technical field:
The utility model relates to the wheel noise reducing damping ring that uses on a kind of train.
Background technology:
Railway is one of main communications and transportation mode of China, and along with the competition of development and national economy and other transportation modes, it is the epoch of feature that Chinese Railway has striden into " high speed passenger transportation, heavily loaded shipping ".Yet, the increase that " at a high speed " and " heavy duty " simultaneously also brings environmental noise of train, noise is serious is polluting city environment, influences people's life, work, health.Along with the raising day by day of people's living standard, people are also more and more higher to the requirement of the comfort level of life, solve the environmental noise of train problem and begin more and more to be subjected to attention both domestic and external.
Reduce environmental noise of train now and mainly contain three kinds of methods, the one, install sound-proof wall additional along the line, the 2nd, transform track and railway roadbed basis, the 3rd, on wheel, take the vibration and noise reducing measure.It is long that railway in the city installs the sound-proof wall circuit along the line additional, and this just causes input cost too high, and because the high restriction of wall, sound-proof wall does not have effect substantially for the resident of skyscraper, and developed countries such as present America and Europe also abandon this method substantially; To the transformation of track is to take gapless rail and track polishing substantially, and present track is treatable substantially finishes dealing with, and is the sampling solid bed to the transformation of railway roadbed, and there is the cost height equally in this method, and the cycle is long, is unfavorable for the defective of constructing; Wheel-rail noise is one of principal element of producing of railroad noise, and it is low to carry out the vibration and noise reducing relative cost at wheel, easy construction, and the technology of wheel vibration and noise reducing is also developed day by day.Present domestic most of wheel is not taked noise reduction measure, the wheel of taking noise reduction measure is additional shock attenuation unit on wheel mostly, be connected with wheel by bolt, this method can effectively reduce wheel-rail noise, but its mounting means is inapplicable to some wheel, for example, wheel for Multiple disc brake, just there is not the space that this additional shock attenuation unit is installed, again for example, for in the wheel gauge with the very narrow wheel of outer rim, do not have the space that this additional shock attenuation unit is installed yet, this has just limited the range of use of wheel shock absorber.
Summary of the invention:
The purpose of this utility model provides a kind of wheel noise reducing damping ring, can be when vibration takes place in wheel, produce the interface damping energy dissipation by friction between damping ring and the wheel, can partly play and suppress wheel radially and the laterally effect of modal vibration, thereby obtain noise reduction preferably.
Above-mentioned purpose realizes by following technical scheme:
Wheel noise reducing damping ring, its composition comprises: ring body, have breach on the described ring body, described indentation, there is equipped with flexible connector, and the termination of described ring body has connecting bore.
Described wheel noise reducing damping ring, described ring body section are circular.
The beneficial effects of the utility model:
1. the utility model can produce the interface damping energy dissipation by friction between damping ring and the wheel when vibration takes place wheel, can partly play and suppress wheel radially and the laterally effect of modal vibration, thereby obtain noise reduction preferably.
2. interface adopts the Flexible Connector sealing to make it safe and reliable when using, and improves service life.
3. the utility model adopts the metallic material of special substance to make, and in light weight, volume is little, and cost is low.
4. the utility model takes up room for a short time on wheel, is applicable to the various forms of wheels of existing use, only needs simply process the rim for automobile wheel inboard.
5. the utility model simple installation, easy operating.
6. the utility model is through special surface treatment, has oil resistant dirt, ageing-resistant, heat-resisting characteristics.
Description of drawings:
Accompanying drawing 1 is the structural representation of this product.
Accompanying drawing 2 is that this product is installed in the structural representation on the wheel.
Accompanying drawing 3 is the enlarged drawings at the W position of accompanying drawing 2.
Accompanying drawing 4 is A-A section-drawings of accompanying drawing 3.
Below in conjunction with the concrete embodiment of description of drawings:
As shown in Figure 1, wheel noise reducing damping ring, its composition comprises: ring body 1, have breach on the described ring body, described indentation, there is equipped with flexible connector 2 (as shown in Figure 4), and the termination of described ring body has connecting bore 3.
Described wheel noise reducing damping ring, described ring body section are circular.Damping ring has specific elasticity and surface finish, is installed on the wheel 4 that has half slot, and as shown in Figure 2, when vibration took place wheel, damping ring rubbed with it and produces the interface damping energy dissipation, thereby plays good effect of vibration and noise reduction.Because the damping ring of making is the round steel of minor radius, therefore, damping ring takes up room little, and weight is low.Damping ring is through cooperation has specific friction coefficient with the wheel groove after the special surface treatment, and damping ring can produce best interface damping under this friction coefficient, and surface treated damping ring has good wear-resisting and corrosion stability.Before installing, damping ring only needs wheel is simply processed, open a half slot in the rim for automobile wheel inboard, the elastomeric mounting that utilizes damping ring is on wheel, adopt Flexible Connector to connect damping ring then, damping ring race diameter after the connection is less than the inner ring diameter of wheel half slot, and damping ring can not come off from the wheel half slot.
Claims (2)
1. wheel noise reducing damping ring, its composition comprises: ring body is characterized in that: have breach on the described ring body, described indentation, there is equipped with flexible connector, and the termination of described ring body has connecting bore.
2. wheel noise reducing damping ring according to claim 1 is characterized in that: described ring body section is for circular.
