Abstract
The invention relates to a noise reduction tire, and belongs to the field of tires. The noise reduction tire is provided with a tire body, and is characterized in that linear tread grooves are formed in the circumferential direction of the tire surface of the tire body at intervals, wherein noise reduction devices (A) are machined in the tread grooves; each noise reduction device (A) consists of three parts, i.e. a root part (A1), a middle part (A2) and an end part (A3); each noise reduction device (A) is arched on in the circumferential direction of each tread groove of the tire, and is like a part of a cylinder; the middle parts (A2) of the noise reduction devices (A) are arched grooves. According to the noise reduction tire, an air column on a grounded part is divided into two parts, and the lengths of the two parts are changed along with time, so that the resonant frequency of the air column is continuously changed along with time, the bandwidth of sounds is increased, and the pumping sound production of longitudinal grooves are interrupted according to a certain time sequence to further increase the bandwidth to reduce noise.
Description
Technical field
The present invention relates to tire field, at length say it is a kind of noise reduction tire.
Background technology
Well-known: Noise Generated by Running Vehicles is one of main source of transportation noise, tire contacts with ground as vehicle unique parts, the noise of its generation directly affects the travelling comfort of automobile.In order to limit squeal of tire, the tire tag > > of travel authentication requesting > > and the relevant fuel efficiency of EC1222/2009 < < and other parameters of up-to-date promulgation EC661/2009 < < European Union of European Union automobile Generally Recognized as safe in 2009, this is wherein to tire drag, grabbing property of wet road surface and path link are crossed noise and have been proposed concrete requirement, clearly propose grabbing for the wet road surface of relevant tire the tire tag requirement of performance rate and noise level, on July 1st, 2012, come into effect.
The sound generating mechanism more complicated of tire, noise-reducing design method is a lot.The airborne noise producing for groove, current trend is that the traverse furrow of tire tread pitch designs tinyization.Tiny traverse furrow design, can guarantee wetland earth-grasping force, can reduce the air pumping sounding of traverse furrow and the excitation that pattern block is patted road surface simultaneously.In order to guarantee the drainage performance of tire, the width of longitudinal furrow and number generally can not reduce, and this ring noise that longitudinal furrow is produced becomes the important sources of squeal of tire.
During tire kiss the earth, tread contour groove and road surface form semiclosed luminal structure, air-flow enters inherent some frequency of tube chamber phenomenon that can vibe, resonance frequency depends primarily on the size of groove, and the design of therefore expanding groove resonance noise frequency band is mainly that the geometric properties around groove launches.Main technological means comprises:
1, groove is got not isometricly, and resonance frequency is staggered;
2, similar groove is distinguished to design on depth direction;
3, groove inwall adopts sawtooth design;
The sawtooth design of groove inwall is innovation in recent years, is called as " quiet wall "." quiet wall " is to utilize sawtooth design to change the reflection direction of noise, extends round, and resonance frequency staggers.But in fact the wavelength of airborne noise is much larger than the width of sawtooth, so sawtooth has muchly to the end that has influence on of squeal of tire, is worth discussion.
Above design processing more complicated, and " quiet wall " in tire production process, and tiny sawtooth is easily stained, has the problem of the presentation quality that affects tire.
Summary of the invention
Object of the present invention is just to overcome the deficiencies in the prior art, and a kind of noise reduction tire is provided, simple in structure, realizes the function that reduces longitudinal furrow noise.
The present invention adopts following technical solution: a kind of noise reduction tire, be provided with carcass, the tyre surface that it is characterized in that carcass is circumferentially interval with linear groove, in groove, be processed with denoising device (A), denoising device (A) is comprised of root (A1), middle part (A2), end (A3) three parts, denoising device (A) is curved in study on tire pattern circumferential direction, a similar cylindrical part, and denoising device (A) middle part (A2) is arc groove.
The present invention also can be achieved by the following measures: the length of denoising device (A) is (l), and width is (w), is highly (h); Length (l) is that l is greater than b, is less than 3b with the pass of the width (b) of groove; Width (w) is less than apart from groove width (b1) corresponding to groove distance from bottom height (h); Highly (h) is less than the degree of depth h2 of groove.
In denoising device (A), root (A1) width is w/2, and middle part (A2) width is w/4, and end (A3) width is w/4; Root (A1) length is l, and the groove depth of middle part (A2) arc groove is h1, and middle part (A2) length is l-2*h1, and end (A3) length is l; Root (A1) is highly h, and middle part (A2) is highly h-h1, and end (A3) is highly h.
Denoising device (A) is incorporated in the inner radial wall and inner circumferential wall of circumferential groove of carcass.
Minimum 7 of the number of denoising device (A) in the circumferential groove of wall scroll, maximum 11.
In the same groove of tire and ground contact area, no more than two denoising devices (A).
The invention has the beneficial effects as follows, the air column at ground connection place is divided into two parts, and two-part length temporal evolution, the resonance frequency of air column is constantly changed in time, and the bandwidth of sound increases, and interrupts longitudinal furrow pumping sounding with certain sequential, further increase bandwidth, reduce noise.
