Abstract
The invention aims at solving a problem of poor noise performance and the violation of a development concept of green tire and low-noise tire of traditional tires. For solving the technical problems, the invention provides a tire surface pattern for reducing tire noise. The pattern comprises pattern grooves and pattern blocks. The pattern grooves are arranged along a circumferential direction of the tire surface. The pattern grooves are composed of continuous pitches, wherein a scattering column is arranged in each pitch. The width of at the scattering column is larger than the width of the two ends of the pitch. With the pattern provided by the invention, air column resonance noise of tire longitudinal patterns can be reduced, and tire drainage characteristics can be satisfied.
Description
Technical field
The invention belongs to a kind of tire tread pattern structure, be specifically related to a kind of tread contour that reduces squeal of tire.
Background technology
Along with being on the increase of vehicle, traffic noise pollution has influenced city dweller's normal life, and wherein the vehicle noise source is the pith of traffic noise pollution.When vehicle reached certain speed, squeal of tire will show out and occupy main status especially.In order to limit the size of squeal of tire, 2009 the up-to-date promulgation EC661/2009 of European Union " authentication requesting that travels of European Union's automobile Generally Recognized as safe " with EC1222/2009 " tire tags of relevant fuel efficiency and other parameters ", this wherein crosses noise to tire drag, wet grabbing property of road surface and path link and has proposed concrete requirement, clearly propose grabbing the tire tag requirement of performance rate and noise level, come into effect on July 1st, 2012 for the wet road surface of relevant tire.Rules similarly come into effect in Japan, and the U.S. also will implement in the near future.Yet China does not put into effect wet and slippery about tire and concrete statutory standard noise as yet.
Studies show that the squeal of tire of running at high speed mainly is the aerodynamics noise that is produced by tread contour groove and air.In the tire rolling process, circumferential pattern groove internal gas flow when being subjected to the tyre surface distortion can produce noise, and the cros-rib tread groove can produce tangible pump and inhale noise.Inhale noise if can effectively control the noise of tire longitudinal groove and the pump of cros-rib tread groove, just can improve the squeal of tire performance.For this reason, there are various technical measures to reduce the noise of tire circumferential pattern groove in recent years.
In fact, the racing slick noise is minimum with respect to the noisiness that rib tire is arranged.The existence of decorative pattern will cause the aerodynamics noise effect of tire.The low noise tire decorative pattern also Gonna breakthrough conventional tire Pattern Design of design.Along with the enforcement of European Union's rules label, the popularization of green tire and the attention of tire Combination property, this just needs a tire that has innovation design idea to adapt to the demand in market.
Summary of the invention
The technical problem to be solved in the present invention is that the conventional tire noiseproof feature is bad, does not meet the idea of development of green tire, low noise tire.
In order to solve the problems of the technologies described above, the invention provides a kind of tread contour that reduces squeal of tire, comprise groove and pattern block, groove circumferentially is provided with along tire protector, and groove is made up of continuous pitch, be provided with the scattering post in each pitch, the width of scattering post place pitch is greater than the width at these pitch two ends.
Further, the narrowest width L of place of restriction pitch
2Be the widest part width L
11/4-3/4.
Further, the angle a that limits between adjacent two pitches is not less than 70 °.
Further, the height of restriction scattering post is 1/4-3/4 of the pitch degree of depth.
Further again, restriction scattering post is not more than 1/4 of pitch length apart from the distance c on pitch the widest part limit.
Further, limit in adjacent two grooves, between two nearest pitch the widest part apart from e be not less than pitch long 1/2.
Technique scheme can reach following technique effect:
1, can reduce the gas column resonance noise of tire circumferential pattern, satisfy the draining characteristics of tire simultaneously.
2, can improve the squeal of tire performance.

Fig. 1 is a structural representation of the present invention.
Fig. 2 is along the sectional structure scheme drawing of AA line among Fig. 1.
Fig. 3 is the local enlarged diagram of B among Fig. 1.
The specific embodiment
Shown in accompanying drawing 1,2,3, the invention provides a kind of tread contour that reduces squeal of tire, comprise groove 2 and pattern block 3, groove 2 circumferentially is provided with along tire protector 1, and groove 2 is made up of continuous pitch 21, be provided with scattering post 4 in each pitch 21, the width of scattering post 4 place's pitches 21 is greater than the width at these pitch 21 two ends.
As the embodiment of optimizing, the narrowest width L of place of above-mentioned pitch 21
2Be the widest part width L
11/4, perhaps 2/4, perhaps 3/4, perhaps be the arbitrary numerical value between 1/4 to 3/4.
As the embodiment of optimizing, the angle a between above-mentioned adjacent two pitches 21 is 70 °, perhaps 80 °, and perhaps 100 °, perhaps 120 °, perhaps greater than arbitrary numerical value of 70 °.
As the embodiment of optimizing, the height of above-mentioned scattering post 4 is 1/4 of pitch 21 degree of depth, perhaps 2/4, perhaps 3/4, and perhaps be the arbitrary numerical value between 1/4 to 3/4.
As the embodiment of optimizing, above-mentioned scattering post 4 is 1/4 of pitch 21 long d apart from the distance c on pitch 21 the widest part 211 limits, perhaps 1/5, perhaps 1/6, and perhaps less than arbitrary numerical value of 1/4.
As the embodiment of optimizing, in above-mentioned adjacent two grooves 2, between two nearest pitch 21 the widest part apart from e is pitch 21 long 1/2, perhaps 2/3, perhaps 3/4, perhaps greater than arbitrary numerical value of 1/2.。
A is the angle between adjacent two pitches 21 among Fig. 3, and c is the distance of scattering post 4 apart from pitch 21 the widest part limits, and d is the length of pitch 21, and e is in adjacent two grooves 2, the distance between two nearest pitch 21 the widest part.The cross-sectional plane of above-mentioned scattering post 4 can be circle, also can be polygon, for example pentagon, hexagon etc., and above-mentioned groove 2 forms the meander configuration decorative pattern on tire protector 1.
