Abstract
The utility model provides a kind of block-type tread, effectively can reduce the noise of decorative pattern, and very little on the impact of decorative pattern mechanical property.In the cross groove of block-type tread, rational height is higher, and length is longer, and thickness is thicker and in the protrusion of upper thick and lower thin trend, two sides of protrusion arrange crisscross groove respectively, and the top of protrusion transversely arranges breach in groove direction.
Description
Technical field:
The present invention relates to tire for vehicles field, particularly relate to the cross groove designing technique of tire block-type tread, the technology of block-type tread cross groove noise when particularly reducing tire rolling.
Background technology:
The groove of tire, particularly cross groove, be to provide the principal element of tire tread mechanical property, but be also that tire produces one of principal element of noise simultaneously, wherein the cross groove of tire block-type tread is usually wider, and the degree of depth is deep, and therefore block-type tread has superior mechanical property, can be applicable to poor road surface, but its noise is more much larger than other types decorative pattern.Almost be difficult at present see specially for the noise reduction technology of block-type tread, and various decorative pattern noise reduction technologies common are at present difficult to be applied on block-type tread, because these technology or extremely limited to the noise reduction of block-type tread, or be difficult to meet the requirement maintaining block-type tread mechanical property.Such as Authorization Notice No. is that " high-performance tire " of CN 2883049Y patent discloses a kind of technology reducing squeal of tire, certain effect is had to various types of decorative pattern (being non-block-type tread especially), but its shortcoming needs additionally loaded down with trivial details operation and cost, be difficult to accomplish the smooth attractive in appearance of weighting material and tread surface, almost there is no practicality, and limited to the noise reduction of block-type tread.
Summary of the invention:
The object of the present invention is to provide a kind of cross groove designing technique of tire block-type tread, solve in prior art the mechanical property that should maintain block-type tread, again simple effectively reduce large width cross groove produce the technical matters of noise.
This block-type tread of the present invention, in its cross groove, rational height is higher, length is longer, thickness is thicker and in the protrusion of upper thick and lower thin trend, the height of protrusion is not less than 70% of cros-rib tread trench depth, the length of protrusion is not less than 80% of cross groove length, the angular range of protrusion and cross groove undercutting plane is 70-90 °, two sides of protrusion are arranged parallel or close to the transverse concave groove of parallel tread surface respectively, and vertical with transverse concave groove or subvertical longitudinal fluting, the top of protrusion transversely arranges breach in groove direction, breach total length is not more than 40% of protrusion length.
Further, the nominal thickness of its any one level attitude of protrusion in described cross groove is not less than 50% of identical level attitude cross groove width, disregards the rounding part of cross groove bottom position.
Further, the degree of depth of any one transverse concave groove of two side of protrusion in described cross groove is not less than 30% of this groove level attitude protrusion nominal thickness, and any one longitudinal fluting is not less than 20% of this level attitude protrusion nominal thickness in the degree of depth of any level attitude.
The present invention compares with prior art, and its effect is actively with obvious.The present invention is provided with highly higher in the large width cross groove of block-type tread, length is longer, the protrusion that thickness is thicker, serve the effect reducing cross groove width, effectively can reduce the noise of cross groove, and the thickness of protrusion is upper thick and lower thin trend, the groove in length and breadth at side and top and breach design make protrusion perpendicular to the vertical stiffness of cross groove undercutting plane and greatly reduce perpendicular to the lateral rigidity of protrusion side, effectively reduce the impact of protrusion on block-type tread mechanical property.As a rule, the vertical stiffness of protrusion and lateral rigidity low then little to the Effect on Mechanical Properties of cross groove, but be unfavorable for the further reduction of cross groove noise, otherwise, the vertical stiffness of protrusion and lateral rigidity height then become large to the Effect on Mechanical Properties of cross groove, but be conducive to the further reduction of cross groove noise, therefore by selecting the length of different transverse concave grooves and longitudinal fluting, width, the degree of depth and quantity, vertical stiffness and the lateral rigidity of different protrusions can be obtained, reach the balance of cross groove noise and mechanical property.
The material that the material that protrusion involved in the present invention in addition uses and tire tread use is consistent, can directly and tire tread one method of reinstating sulfuration generate, without the need to extra operation and cost simultaneously.
