Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Example (b):

as shown in fig. 1 and 2, a double-guide radial tire comprises a tire body 1 and a tread 2, wherein a central pattern groove 3 is arranged on the tread 2 along the circumferential central position, and tread pattern units a are arranged on two sides of the central pattern groove 3 in a reverse symmetry manner. The tread pattern elements a on both sides comprise a first straight guide groove 4 and a second straight guide groove 5, respectively, wherein: the first straight guide groove 4 is arranged close to the central pattern groove 3, and the first straight guide groove 4, the second straight guide groove 5 and the central pattern groove 3 are arranged in parallel. The design of the reverse symmetrical pattern with the central pattern groove 3 as the center leads the tire to have no directional requirement when loading, the positive and negative directions are both suitable, the installation requirement is reduced, and the service life is prolonged. The three-large straight groove design of the central pattern groove 3, the first straight guide groove 4 and the second straight guide groove 5 provides good linearity and guidance for the tire, particularly meets the requirement that the controllability is sensitive to the response of a steering wheel, and comprehensively achieves the advantages of good guidance and riding comfort.

As shown in fig. 1 and 2, the width of the first straight guide groove 4 is greater than the width of the second straight guide groove 5, the width of the center lug groove 3 is less than the width of the first straight guide groove 4, and the ratio of the width of the first straight guide groove 4 to the width of the second straight guide groove 5 is 1:4.5 to 1:5.5, for example: the width of the central pattern groove 3 can be set to be 9mm, the width of the first straight guide groove 4 is set to be 9.8mm, and the width of the second straight guide groove 5 is set to be 2.0 mm; in addition, the depth of the first straight guide groove 4 is 7.5mm, the depth of the second straight guide groove 5 is 5.0mm, and the design is used for improving the stability in the high-speed driving process and reducing the tread creeping on the premise of ensuring the excellent drainage performance on two sides, thereby reducing the rolling resistance.

As shown in fig. 1 and 2, arc-shaped fine steel rib 6 is arranged between the central pattern groove 3 and the first straight guide groove 4, the arc-shaped fine steel rib 6 is sequentially arranged along the circumferential direction of the tread 2, and the arc-shaped fine steel rib is arranged by using a static gene technology, so that the distance between the adjacent arc-shaped fine steel ribs 6 is different in size, and the pattern blocks are different in size at each obtained pitch, namely: the characteristic that the gene arrangement is not repeated is applied to the structural design of the pattern blocks, the optimal arrangement is calculated through computer operation optimization sequencing, and the structural design can reduce the frequency generated by air compression and release among patterns, so that the purpose of reducing noise is achieved, and driving and riding personnel are more quiet and comfortable.

As shown in fig. 1 and 2, an inclined thin steel sheet rib 7 is arranged on one side of the second straight guide groove 5, which is far away from the central rib groove 3, the inclined thin steel sheet rib 7 and the arc-shaped thin steel sheet rib 6 on the same side are correspondingly arranged, a transverse drainage groove 8 is arranged between the adjacent inclined thin steel sheet ribs 7, one end of the transverse drainage groove 8 extends to the edge of the tread 2, and a support thin steel sheet rib 9 is communicated between the other end of the transverse drainage groove 8 and the second straight guide groove 5 on the same side; meanwhile, under the dry ground condition, the structural design can soften the rigidity of the tire tread 2, provide stronger ground grabbing force, ensure the riding safety and increase the comfort. The contained angle between horizontal water drainage tank 8 and the straight guide way 5 of second is between 85 ~ 95, and this kind of big right angle design of similarity can provide powerful rigidity and prevent to warp, increases drainage simultaneously.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
