Description

Technical Field

[0001] The present invention relates to the technical field of tires, in particular to a tire muffler and a disassembly structure thereof. Background Art

[0002] Tires are circular, rolling, elastic rubber products that are mounted on various vehicles or machines and are grounded and rolled. They are usually installed on metal rims and can support the vehicle body, cushion external impacts, achieve contact with the road surface, and ensure the vehicle's driving performance. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects during driving. Therefore, they must have high load-bearing capacity, traction performance, and cushioning performance. At the same time, they are also required to have high wear resistance and flexibility resistance, as well as low rolling resistance and heat generation.

[0003] Since tires generate a certain amount of tire noise during driving, sound-absorbing cotton is currently used to absorb and reduce tire noise. When repairing the tire, the sound-absorbing cotton needs to be cut before repair, which affects subsequent repairs. At the same time, the sound-absorbing cotton is also scrapped when the tire is replaced. There are also some methods that use resonators to be set inside the tire. The resonance cavity filters the tire noise in a specific frequency band to achieve the purpose of reducing tire noise. However, it is inconvenient to assemble the resonator inside the tire, and the installation stability of the resonator is poor.

[0004] To this end, we propose a tire muffler and also disclose a disassembly structure of the tire muffler. Summary of the Invention
