Description

Technical Field

[0001] The utility model is used in the field of automobiles, and particularly relates to a tire, a wheel and a vehicle. Background Art

[0002] A tire is one of the important components of an automobile. It directly contacts the road surface and, together with the vehicle suspension, mitigates the impact received during vehicle driving, ensuring good riding comfort and driving smoothness of the vehicle; ensuring good adhesion between the wheel and the road surface, improving the tractive performance, braking performance and passing performance of the vehicle; and bearing the weight of the vehicle. The important role played by the tire in the vehicle has been increasingly emphasized by people.

[0003] Existing tires adopt a symmetric structure design, making it difficult to distinguish the inner and outer sides of the tire, and the installation convenience is poor. Moreover, for symmetric tires, it is difficult to reconcile the contradictions among the comfort, handling performance and durability of the tire. Summary of the Utility Model

The first sidewall 101 and the second sidewall 102 do not contact the ground, and the sidewalls mainly work in a flexed state and must withstand large mechanical deformation. The thickness of the sidewalls can be slightly thinner than the tread 103. The inner edge of the first sidewall 101 forms a first tire lip 104, and the radial distance from the first tire lip 104 to the tread 103 is the first sidewall height h1, and the inner edge of the second sidewall 102 forms a second tire lip 105, and the radial distance from the second tire lip 105 to the tread 103 is the second sidewall height h2, and h1>h2. The first bead 104 and the second bead 105 are used to cooperate with the wheel hub 200 to assemble the tire 100 on the wheel hub 200, so that the tire 100 can be firmly fixed on the wheel hub 200 and resist the force that causes the outer tire to separate from the wheel hub 200 when the vehicle is running.

[0027] See also Figures 1 - 3 The embodiment of the utility model provides a tire 100, including a first sidewall 101, a second sidewall 102 and a tread 103 between the first sidewall 101 and the second sidewall 102, and the tread 103 of the tire 100 is used to directly contact the road surface. The first sidewall 101 and the second sidewall 102 do not contact the ground. The sidewalls mainly work in a flexed state and must withstand large mechanical deformation. The thickness of the sidewalls can be slightly thinner than the tread 103. The inner edge of the first sidewall 101 forms a first tire lip 104, and the inner edge of the second sidewall 102 forms a second tire lip 105. The diameter of the first tire lip 104 is R1, and the diameter of the second tire lip 105 is R2, and R2>R1. The first bead 104 and the second bead 105 are used to cooperate with the wheel hub 200 to assemble the tire 100 on the wheel hub 200, so that the tire 100 can be firmly fixed on the wheel hub 200 and resist the force that causes the outer tire to separate from the wheel hub 200 when the vehicle is running.

[0028] In the embodiment of the utility model, the tire 100 adopts an asymmetric design in which the first sidewall 101 and the second sidewall 102 are unequal. When used, it can be matched with the wheel hub 200 which also adopts an asymmetric design, wherein the first sidewall height of the first sidewall 101 is greater, and the second sidewall height of the second sidewall 102 is smaller. One end of the tire 100 has a larger opening, and the other end has a smaller opening. On the one hand, it makes it easier to distinguish the inner and outer surfaces of the tire 100, and only one-way insertion is required during installation, which makes installation more convenient. On the other hand, the asymmetric tire 100 makes the cross-section of the tire 100 and the wheel hub 200 form a triangular stable structure, which has the characteristics of tires with different aspect ratios, can not only improve the handling performance, but also ensure comfort and durability, and also show a more advanced feel.

[0029] It can be understood that the tire 100 is an annular elastic rubber product. A rubber sealing layer specifically used for air sealing can be provided on the inner wall of the tire 100. Further, an adhesive layer can be attached under the rubber sealing layer. When the tire 100 is perforated, the adhesive layer can automatically bond the punctured hole.

[0030] In some embodiments, referring to Figure 2 、 Figure 3 , the tire 100 is an inflated tire 100. A tire cavity is formed inside the tire 100, and the tire cavity is used for inflating gas, and air can be pressed into the tire cavity. In this embodiment, the tire 100 adopts an asymmetric design, and the radial thickness of the tire cavity gradually decreases from the first tire side 101 to the second tire side 102. After the asymmetric tire 100 and the wheel hub 200 are assembled, a triangular stable structure is formed in the cross-section of the tire 100 and the wheel hub 200, combining the characteristics of tires 100 with different aspect ratios, which can not only improve the handling performance but also ensure comfort and durability.

[0031] In some embodiments, referring to Figure 1 、 Figure 2 , a reinforcing rib 106 is provided in the tire cavity, and the reinforcing rib 106 protrudes from the tire wall of the tire 100 into the tire cavity. The reinforcing rib 106 is used to enhance the vertical supporting force of the tire wall, and can still travel at low speed under the condition of insufficient air pressure, and has resistance to side wear and blowout.

[0032] Further, referring to Figure 1 、 Figure 2 , the reinforcing rib 106 includes a tire wall reinforcing rib, and the tire wall reinforcing rib extends from the inner wall surface of the first tire side 101 to the inner wall surface of the tread 103, and a plurality of tire wall reinforcing ribs are arranged at intervals in the circumferential direction.

The first bead 104 of the tire 100 is assembled on the first rim 201, and the second bead 105 of the tire 100 is assembled on the second rim 202. In this embodiment, the asymmetric wheel hub 200 and the tire 100 form a triangular stable structure in the cross-section of the tire 100 and the wheel hub 200, which is convenient for installation. It only needs to be sleeved in one direction, and it is easy to distinguish the inside and outside. The outer surface has a small aspect ratio, good controllability, and at the same time shows a sense of luxury. The inner surface has a large aspect ratio, is soft, comfortable and noise-limiting.
