Detailed Description

As shown in fig. 1, the present embodiment describes a wet and skid resistant motorcycle tire, which includes a tire crown 1, a plurality of groups of main grooves 4 are disposed on the tire crown 1, the main grooves 4 divide the tire crown 1 into a plurality of pattern blocks, drainage grooves 2 are disposed on the pattern blocks, the drainage grooves 2 and the main grooves 4 are both disposed along the opposite direction of the tire advancing, obliquely from the equatorial plane to the sidewall, and the main grooves 4 and the drainage grooves 2 are symmetrically disposed along the equatorial plane of the tire.

As shown in fig. 1, the main grooves 4 include first groove groups 41 and second groove groups 42, the first groove groups 41 and the second groove groups 42 being alternately arranged on one side of an equatorial plane in the circumferential direction of the tire, the first groove groups 41 and the second groove groups 42 on both sides of the equatorial plane being symmetrical along the equatorial plane.

As shown in fig. 1, the first groove group 41 includes a first inclined groove 411, the first inclined groove 411 is disposed obliquely from inside to outside along a direction opposite to a rolling direction of the tire, a first diversion groove 431 is formed at an end of the first inclined groove 411 away from an equatorial plane, the first diversion groove 431 is communicated with the first inclined groove 411, and an angle between the first inclined groove 411 and the equatorial plane is smaller than an angle between the first diversion groove 431 and the equatorial plane.

As shown in fig. 1, the second groove group 42 includes a second inclined groove 421 and a third inclined groove 422, the second inclined groove 421 and the third inclined groove 422 are in the same straight line and are both parallel to the first inclined groove 411, the second inclined groove 421 is close to the equatorial plane, and the third inclined groove 422 is close to the sidewall. The end part, far away from the equatorial plane, of the second inclined groove 421 is provided with a second diversion groove 432, the end part, far away from the equatorial plane, of the third inclined groove 422 is provided with a third diversion groove 433, the second diversion groove 432 is communicated with the second inclined groove 421, the third diversion groove 433 is communicated with the third inclined groove 422, and the second diversion groove 432 and the third diversion groove 433 are parallel to the first diversion groove 431. For convenience of description, in the present application, the first direction-changing groove 431, the second direction-changing groove 432, and the third direction-changing groove 433 are collectively referred to as a direction-changing groove.

In the running process of the motor vehicle, as the first inclined groove 411, the second inclined groove 421 and the third inclined groove 422 on the main groove 4 are all obliquely arranged, when the tire rolls on the ground, the main groove 4 on the tire can be always contacted with the ground, so that the water between the tire and the ground can enter the main groove 4 at any time. Receive the extrusion of tire and ground, water between tire and the ground can enter into first chute 411 fast, in second chute 421 and the third chute 422, later rivers can follow first chute 411, second chute 421 and third chute 422 get into the diversion inslot, after the water conservancy diversion in diversion groove, finally discharge from the diversion inslot, the axial of tire is deviated from more to the rivers outflow direction of following the diversion inslot exhaust, consequently, extrude the both sides diffusion that the discharged rivers can be towards the tire from the tire, reduce the impact of rivers to the motor vehicle.

Because the first chute group 41 and the second chute group 42 divide the tire crown 1 into a plurality of pattern blocks, a mold is needed in the process of vulcanizing the tire, a cavity with the same shape as the pattern blocks is designed on the mold, the cavity is generally provided with vent holes, the mold wraps the outer side of the embryo, high-pressure air is injected into the middle of the embryo, so that the embryo is tightly attached to the mold, after the air in the cavity of the mold is completely removed, rubber enters the vent holes, and finally, the tire hair is formed after demolding. In order to reduce the number of air vents on the mold, reduce the number of tire blanks and improve the aesthetic degree of the tire, the connectivity of the cavity for molding each pattern block needs to be improved, so that the air in the cavity can be exhausted by using the minimum number of air vents. Wherein, interval between second chute 421 and the third chute 422, the decorative pattern piece of second chute 421 and third chute 422 both sides just can be even as an organic whole through the decorative pattern piece between second chute 421 and the third chute 422 like this, and the die cavity of shaping second chute 421 and the decorative pattern piece of third chute 422 both sides can communicate each other promptly, just can set up the exhaust hole in the die cavity of one side this moment and just can discharge the air in the die cavity of both sides smoothly, guarantees the quality of vulcanizing.

Similarly, as shown in fig. 1, a blocking block 4321 may be further protruded from the middle of the second direction-changing groove 432, and the blocking block 4321 is integrally connected with the blocks at two sides of the second direction-changing groove 432. At this time, the cavities for forming the pattern blocks on the two sides of the second diversion groove 432 can be communicated through the cavities for forming the partition blocks, and air in the cavities on the two sides can be smoothly discharged only by arranging the vent holes in the cavity for forming the pattern blocks on one side of the second diversion groove 432, so that the vulcanization quality is ensured.

As shown in fig. 1 and 2, the drainage groove 2 includes a plurality of channels, circular grooves 3 are respectively formed at two ends of each drainage groove 2, a protrusion 31 is convexly arranged at the central part of each circular groove 3, the height of the protrusion 31 is lower than the outer surface of the tire crown 1, that is, the protrusion 31 does not exceed the tire tread, and an annular drainage structure is formed between the protrusion 31 and the circular groove 3. The circular groove 3 that every drainage ditch groove 2 is close to equatorial plane one end is interior circular groove 32, and the circular groove 3 of the other end is excircle groove 33, and interior circular groove 32 and excircle groove 33 are located the both sides of drainage ditch groove 2 respectively to interior circular groove 32 and excircle groove 33 all communicate and tangent with drainage ditch groove 2. At this moment, at the in-process of traveling, the water between decorative pattern piece and the ground can enter into the great interior circular slot 32 of area at first fast for the speed that rivers assemble between decorative pattern piece and the ground, and the water that gets into in the interior circular slot 32 can smoothly get into in escape canal 2 after the annular space of interior circular slot 32 water conservancy diversion, thereby promotes the smooth and easy nature that rivers flow, promotes the velocity of flow, and later rivers discharge after the water conservancy diversion of excircle groove 33 in entering excircle groove 33 again.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
