[0031] Multiple groups of first transverse grooves 17 with equal spacing are provided on the outer wall of the rubber wheel body 1 between the first longitudinal groove 18 and the thin buffer groove 2, and one end of the first transverse groove 17 extends to the inside of the first longitudinal groove 18, and the other end of the first transverse groove 17 extends to the outside of the thin buffer groove 2, and multiple groups of second transverse grooves 16 with equal spacing are provided on the outer wall of the rubber wheel body 1 between the second longitudinal groove 10 and the first longitudinal groove 18, and one end of the second transverse groove 16 extends to the inside of the second longitudinal groove 10, and the other end of the second transverse groove 16 extends to the inside of the first longitudinal groove 18;

[0032] A plurality of groups of third transverse grooves 14 are provided on the outer wall of the rubber wheel body 1 between the third longitudinal groove 9 and the fourth longitudinal groove 11 at equal intervals, and one end of the third transverse groove 14 extends to the inside of the third longitudinal groove 9, and the other end of the third transverse groove 14 extends to the inside of the fourth longitudinal groove 11;

[0033] A plurality of groups of fourth transverse grooves 15 are provided on the outer wall of the rubber wheel body 1 between the fourth longitudinal groove 11 and the protrusion 12 at equal intervals, and one end of the fourth transverse groove 15 extends to the inside of the fourth longitudinal groove 11, and the other end of the fourth transverse groove 15 extends to the outside of the protrusion 12;

[0034] By machining the first longitudinal groove 18, the second longitudinal groove 10, the third longitudinal groove 9, and the fourth longitudinal groove 11 on the outer surface of the rubber wheel body 1, and machining the first transverse groove 17, the second transverse groove 16, the third transverse groove 14, and the fourth transverse groove 15 on the outer surface of the rubber wheel body 1, the first transverse groove 17 is cross-connected with the first longitudinal groove 18, the first longitudinal groove 18 is cross-connected with the second transverse groove 16, the second transverse groove 16 is cross-connected with the second longitudinal groove 10, the third transverse groove 14 is cross-connected with the third longitudinal groove 9, the third transverse groove 14 is cross-connected with the fourth longitudinal groove 11, and the fourth longitudinal groove 11 is cross-connected with the fourth transverse groove 15. The longitudinal grooves are used to prevent hydroplaning. When the road surface and the tire are separated by a layer of water when in contact, the longitudinal grip is seriously lost and the slide occurs. The higher the speed and the deeper the water, the greater the risk of slide. The transverse grooves reduce or prevent hydroplaning. They can The water film between the tire and the road surface is broken, and the countless sipes on the edge of the tread strengthen this effect. Hydroplaning refers to the tire losing grip on slightly wet roads. At this time, the tread pattern and the road surface are separated by a layer of water film and cannot directly contact each other. When the tire is driving on a wet and slippery road surface, the bumps 12 and the anti-slip blocks 13 can help squeeze out the water between the tire and the road surface to improve the grip. The tread of a solid polyurethane tire includes a rubber body and a polyurethane material. The polyurethane material is located in the outer layer. The polyurethane part improves the wear resistance of the tire tread. The rubber material tread and the polyurethane material tread can be made into tires through composite extrusion or casting and then co-vulcanization with the rubber tire body. The anti-skid polyurethane rubber tire tread texture structure and the multiple groups of grooves on the rubber wheel form excellent anti-skid performance, which improves the grip of the tire and extends the service life of the tire.

The surface of the roller shaft 7 on one side of the right annular frame 5 is provided with a right clamping sleeve 4, and the surface of the roller shaft 7 on one side of the left annular frame 3 is provided with a left clamping sleeve 8;

[0038] When the load-bearing capacity of the tire is too large, in the initial stage, the diameter of the rubber wheel body 1 is larger than the left ring frame 3 and the right ring frame 5. When unloaded, the roller 6 does not contact the ground, and the rubber wheel body 1 is squeezed and deformed. Under the buffering of the fine buffer groove 2, the roller 6 contacts the ground, and the roller shaft 7 movably supports the roller 6. The roller 6 improves the load-bearing performance of the tire. The left ferrule 8 and the right ferrule 4 are connected to the roller shaft 7 to facilitate the support and limitation of the roller shaft 7, thereby achieving excellent load-bearing performance of the tire and preventing the tire from being squeezed and damaged due to excessive load-bearing capacity.

The longitudinal grooves are used to prevent hydroplaning. When the tire is running on a slippery road, the bumps 12 and the anti-slip block 13 can help squeeze out the water between the tire and the road surface to improve the grip;

[0041] Step 2. When the load-bearing capacity of the tire is too large, in the initial stage, the diameter of the rubber wheel body 1 is larger than the left ring frame 3 and the right ring frame 5. When unloaded, the roller 6 does not contact the ground, and the rubber wheel body 1 is squeezed and deformed. Under the buffering of the fine buffer groove 2, the roller 6 contacts the ground, and the roller shaft 7 movably supports the roller 6. The roller 6 improves the load-bearing performance of the tire. The left ferrule 8 and the right ferrule 4 are connected to the roller shaft 7 to facilitate the support and limitation of the roller shaft 7, so as to complete the tire tread texture structure and the use of the rubber wheel.
