[0001] The utility model relates to the technical field of improving the sound insulation effect of automobile tires, and specifically relates to a sound insulation structure for improving the sound insulation effect of automobile tires. Background Technique
[0002] With the rapid development of the automobile industry, people's requirements for the comfort of automobiles are getting higher and higher. As an important component of the automobile in contact with the ground, the sound insulation performance of the tire directly affects the comfort of the whole vehicle. Traditional tires will generate relatively large noises during driving, which not only affects the driving experience but also may cause noise pollution to the environment.
[0003] However, the existing methods for reducing tire noise still have certain limitations in practical applications and cannot effectively absorb and dissipate the low-frequency noise and high-frequency vibration generated when the tire rolls, resulting in limited improvement in the tire sound insulation effect and poor sound insulation effect.
[0004] Therefore, based on the above technical problems, it is necessary for those skilled in the art to develop a sound insulation structure for improving the sound insulation effect of automobile tires. Content of the Utility Model
[0005] The purpose of the utility model is to provide a sound insulation structure for improving the sound insulation effect of automobile tires to solve the problems raised in the above background technique.
[0006] To achieve the above purpose, the utility model provides the following technical scheme:
[0007] A technical scheme of a sound insulation structure for improving the sound insulation effect of automobile tires includes a tire, a sound insulation cotton is arranged on the inner wall of the tire, and the sound insulation cotton is composed of a polyurethane matrix. A number of micropores are arranged in the polyurethane matrix. A number of transverse reinforcing fibers are arranged horizontally in the polyurethane matrix, and a number of longitudinal reinforcing fibers are arranged vertically. A glue layer is arranged between the polyurethane matrix and the inner wall of the tire.
[0008] As a preferred technical scheme, the aperture of the micropores is 0.1 mm to effectively absorb and disperse the vibration and noise generated by the tire during driving on the premise of not affecting the strength of the tire.
[0009] As a preferred technical scheme, the transverse reinforcing fibers and the longitudinal reinforcing fibers are glass fibers or carbon fibers to improve the tensile strength and tear resistance of the polyurethane matrix, thereby ensuring the stability and durability of the sound insulation cotton during long-term use.
[0010] As a preferred technical scheme, the glue layer is an organosilicon sealant glue, which has good bonding performance and aging resistance, ensuring that the sound insulation cotton is tightly combined with the inner wall of the tire and avoiding abnormal noises during driving.
[0011] As a preferred technical solution, the thickness of the sound-absorbing cotton is 5 millimeters to ensure the best sound insulation effect without affecting the tire performance.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] The present utility model is a sound insulation structure for improving the sound insulation effect of automobile tires. Through the combination of its microporous structure and reinforcing fibers, the sound-absorbing cotton can effectively absorb and disperse the vibration and noise generated during the driving of the tire. In addition, the use of the polyurethane matrix ensures that the sound-absorbing cotton has good elasticity and durability, thus maintaining its sound insulation effect during long-term use. The present utility model not only improves the comfort of the automobile but also reduces the noise pollution to the environment. By using the silicone sealant as the adhesive layer, the tight bonding between the sound-absorbing cotton and the inner wall of the tire is ensured, avoiding the abnormal noise that may occur during driving, and having high practical value and market application prospects.
