Problems solved by technology

[0003] When the vehicle is running, the tire rolls with the wheel. At this time, due to the characteristics of the tire compound, the tire structure, the tire pattern, etc., the tire will vibrate due to repeated force, and this vibration will cause tire noise (that is, when the tire rolls on the bottom surface) generated noise), thereby affecting the sensory experience of the passengers and causing discomfort

no. 2 Embodiment

[0054] The second specific embodiment of the present invention provides a noise-reducing tire manufacturing process, which is suitable for the noise-reducing tire provided by the first specific embodiment of the present invention.

[0055] Specifically, the noise reduction tire manufacturing process includes the following steps:

[0056] First, according to the circumference of the position where the anti-seismic and noise-reducing material needs to be attached in the noise-reducing tire, the anti-seismic and noise-reducing material is cut into a flat strip structure with a preset length;

[0057] Then, attach the first anti-vibration and noise-reducing material 7 to the inner side of the air-holding layer 5 in the shoulder 2 of the green tire (for the specific position, refer to figure 1 ), or the first anti-seismic and noise-reducing material 7 is sandwiched in the air-retaining layer 5 in the shoulder 2 (see figure 2 ); the second anti-shock and noise-reducing material is...

no. 3 Embodiment

[0061] The third specific embodiment of the present invention provides a wheel, on which the noise reduction tire provided by the first specific embodiment of the present invention is arranged.

Abstract

The invention discloses a noise reduction tire, a manufacturing process thereof and a wheel. Anti-vibration and noise-reduction materials are arranged in tire shoulders of the noise-reduction tire, and furthermore, the anti-vibration and noise-reduction materials are arranged on the tire shoulders of the noise-reduction tire, the inner side of bead filler and the inner side of a tire tread. The noise-reducing tire manufacturing process comprises the following steps: attaching an anti-seismic noise-reducing material into a tire shoulder of a green tire, or attaching the anti-seismic noise-reducing material into the tire shoulder and apex, and attaching the anti-seismic noise-reducing material to the inner side surface of an air-retaining layer in a tread or the outer side surface, close toa buffer layer, of the air-retaining layer in the tread; vulcanization process. Visibly, in the noise reduction tire, the anti-vibration and noise reduction material is arranged at the position, proneto deformation, of the tire, and noise generated in the running process of the tire can be reduced in an absorption mode; moreover, the noise reduction tire manufacturing process is low in technicalrequirement, the anti-noise effect can be achieved only through a simple attaching process, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the technical field of vehicle manufacturing, in particular to a noise-reducing tire, a manufacturing process of the noise-reducing tire, and a wheel. Background technique [0002] Automobiles have become the most common means of transportation today. Moreover, people are very concerned about the driving experience brought by the vehicle during driving. [0003] When the vehicle is running, the tire rolls with the wheel. At this time, due to the characteristics of the tire compound, the tire structure, the tire pattern, etc., the tire will vibrate due to repeated force, and this vibration will cause tire noise (that is, when the tire rolls on the bottom surface) generated noise), thereby affecting the sensory experience of the passengers and causing discomfort. [0004] Therefore, how to reduce or even avoid tire noise is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [00...
