Abstract
The invention discloses a low-noise tread pattern block which comprises a tyre running surface, wherein a plurality of tread pattern grooves and a plurality of tread pattern blocks surrounded by the tread pattern grooves are distributed in the tyre running surface, the edge parts are respectively included between the any surface of the tread pattern blocks and the sidewall surface of the adjacent tread pattern grooves, and the edge parts that an included angle between the trend of the edge parts and the circumferential center line of a tire is greater than or equal to 20 degrees and less than or equal to 90 degrees are arranged in a chamfering structure; and in the cross section of the chamfering structure, the edge of the chamfering is an arc line, a straight line, or a zigzag line composed by more than two of straight-line segments which are sequentially connected, the start and the end of the arc line, the straight line or the zigzag line are respectively arranged in the surface of the tread pattern blocks and the sidewall surface of the tread pattern grooves. According to the invention, the impact noise generated by the edges of the tread pattern blocks are effectively reduced, simultaneously the areas of the tread pattern blocks are reduced, the openings of the tread pattern grooves are expanded, and frictional noise of the tread pattern blocks and the air flow noise in the tread pattern grooves can be reduced.
Description
Technical field:
The present invention relates to the tire for vehicles field, relate in particular to the cros-rib tread piece designing technique of surface of tyre, particularly reduce the shock of pattern block and the technology of frictional noise, concrete is a kind of low noise pattern block.
Background technology:
Squeal of tire mainly is comprised of groove noise (factors such as air pumping, sympathetic response and turbulent flow cause), pattern block noise (factors such as shock and friction cause) and vibration noise (the various vibrations of tire cause).Surface of tyre (being tread) has many positions that fall in to be called as groove, and the position that all the other do not fall in namely is called as pattern block by the position that groove surrounds.That the experiment of squeal of tire mechanism or squeal of tire all shows, groove can produce very large Air Flow noise, if the angle of the sharp-pointed edge of pattern block and the circumferential line of centers of tire more greatly can produce impact noise, the surface of pattern block can produce frictional noise.Therefore, by reducing the quantity of groove, can reduce the noise that is produced by groove, groove quantity has also reduced the fast quantity of decorative pattern when reducing, therefore can reduce simultaneously the noise that shock road surface, pattern block edge produces, but for the in-use performance (driving, braking etc.) that guarantees tire tread, tire tread must will have the groove of sufficient amount, so can not reduce squeal of tire by the method that reduces groove quantity.In prior art, mainly reduce the groove noise by shape, size (length and angle etc.) and the factors such as (distributions) of arrangement of adjusting groove, and the structure and material by adjusting tire and reduce the tire vibration noise with the coupling of vehicle, but the noise that effective means reduces pattern block is proposed not yet.
Summary of the invention:
The object of the present invention is to provide a kind of low noise pattern block, described this low noise pattern block will solve the technical matters that can't reduce the noise that in tread surface, pattern block produces in prior art.
This low noise pattern block of the present invention, comprise a tread surface, the a plurality of pattern blocks that are distributed with a plurality of grooves in described tread surface and surrounded by described groove, wherein, all include separately rib section between the side wall surface of the surface of any one described pattern block and adjacent groove, wherein the angle of trend and the circumferential line of centers of the tire rib section that is greater than or equal to 20 degree and is less than or equal to 90 degree is set to chamfering structure.
Further, in the section of described chamfering structure, the edge of chamfering is camber line or straight line or the tortuous line segment that is linked in sequence and consisted of by plural linear portion, and the starting point of described camber line or straight line or tortuous line segment and terminal point lay respectively in the side wall surface of the surface of pattern block and groove.
Further, described camber line is circular arc, the radius of described circular arc less than the width of its corresponding groove in tread surface 1/3rd and less than its corresponding groove extreme depth 1/5th and less than 1/3rd of the width of its corresponding pattern block in tread surface.
Further, described a plurality of groove includes a plurality of circumferential pattern ditches and a plurality of cross groove.
Further, trend or angle parallel with the circumferential line of centers of tire also is set to chamfering structure less than the 20 rib sections of spending.
Further, in the section of described chamfering structure, the edge of chamfering is linked in sequence when consisting of by plural linear portion, and any one described linear portion is all isometric with an adjacent linear portion.
Principle of work of the present invention is: the present invention has changed traditional pattern block surface and the direct connection mode of groove side wall surface, means by passivation pattern block edge, connect pattern block surface and groove side wall surface, effectively reduced the impact noise of pattern block edge generation, both reduced simultaneously the area of pattern block, also enlarged the opening of groove, thus the frictional noise of pattern block also can be reduced, and reduce the Air Flow noise in groove.By adjusting the radius of circular arc, perhaps substitute arc surface with one or more plane, can and keep at noise reduction finding balance between the decorative pattern propulsive effort.
The present invention and prior art are compared, and its effect is actively with obvious.The rib section of the present invention between tire tread block and adjacent groove arranges chamfering, effectively reduced the impact noise of pattern block edge generation, both reduced simultaneously the area of pattern block, enlarged again the opening of groove, can reduce the frictional noise of pattern block, and reduce the Air Flow noise in groove.
