Technical Field

[0001] The utility model relates to the technical field of tire production, in particular to a tire with low cavity noise. Background Art

[0002] As one of the important parts of a car, automobile tires have a vital impact on the ride comfort of the car. The rapid development of the electric vehicle industry has eliminated the noise impact of the engine, so the cavity noise generated by the tires has attracted more and more attention. Manufacturing a tire with low cavity noise has become a research direction that tire manufacturers pay close attention to.

[0003] The current mainstream low cavity noise tire technology is to stick a circle of sound-absorbing cotton inside the tire to reduce the cavity noise of the tire by absorbing the cavity noise inside the tire. The current mainstream low cavity noise tire technology requires applying a layer of glue inside the tire and then sticking thicker sound-absorbing cotton, which increases the weight of the tire and increases the cost. Although the cavity noise can be reduced, the reduction ability is limited.

[0004] Based on this, a low cavity noise tire is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content

[0027] In one embodiment, Figure 2 As shown, the noise reduction component includes a first sound insulation membrane 3, one end of the first sound insulation membrane 3 is fixedly connected to the inside of the tire body 1, and the end of the first sound insulation membrane 3 away from the tire body 1 is movably abutted against one end of the tire rim 2. A second sound insulation membrane 4 is fixedly connected to the inside of the tire body 1, and the end of the second sound insulation membrane 4 away from the tire body 1 is movably abutted against the other end of the tire rim 2. The circumferential vibration of the air in the tire body 1 is blocked by the first sound insulation membrane 3 and the second sound insulation membrane 4.

[0028] In one embodiment, Figure 1 and Figure 2 As shown, the drainage component includes a tread pattern 5, which is fixedly connected to the outer surface of the tire body 1. Grooves 6 are provided between the tread patterns 5, so that the tire body 1 can discharge water through the grooves 6 when passing through a rainy road section.

A valve core 10 is slidably connected inside the valve seat 7, and a limiting hole 11 is provided on the outer side of the valve core 10. The valve core 10 is placed on the valve seat 7 and an external force is then applied to the valve core 10 so that the limiting hole 11 on the outer side reaches the clamping column 9, so that the valve core 10 can be fixed.
