Abstract

The invention discloses a noise-reduction tire pattern groove which comprises a tire body, wherein pattern groove parts are arranged on the tire body, and comprise groove walls and groove bottoms. The tire pattern groove is characterized in that convex-concave damping structures are arranged in the pattern groove parts. Compared with the prior art, the special convex-concave damping structures are designed in the pattern groove parts, so that viscous damping or acoustic impedance of air flows can be improved very well, the flow velocities of the air flows of semi-closed pattern groove part tube cavities are reduced, the air energy is reduced, the frequency of the air flows within a certain range of the tube cavities is eliminated, the pumping noise of air is reduced, and the resonance probability of an air column is reduced.

Description

technical field

[0001] The invention relates to a noise-reducing tire pattern groove, which is designed with a special tire pattern structure, uses rubber as a sound-absorbing material, learns from the sound-absorbing principle, and uses the energy-dissipating method to consume sound energy, reducing the noise caused by the pattern pump, The noise generated by air column resonance belongs to the tire structure design technology. Background technique

[0002] Tires will produce noise under certain speed conditions. This noise is generally divided into two forms: one is the noise directly radiated by the tire, which is called direct noise. Another type of tire directly or indirectly becomes the excitation source, and the vibration is transmitted to the interior of the car as interior noise, which is called indirect noise. The direct noise of high-speed tires accounts for a large proportion of vehicle noise, so for tire noise, it generally refers to the impact of direct noise...
