Embodiment Construction

[0028] The technical solution of the present invention is not described in detail through the following examples. The following examples are only exemplary and can only be used to explain and illustrate the technical solution of the present invention, rather than being interpreted as a limitation to the technical solution of the present invention.

[0029] Such as Figure 1 to Figure 6 As shown, the low-noise tire of the present application also includes several parts of the wheel core 1, the wheel spokes 2, the wheel rim 3 and the tire skin 4. improvements will be described later.

[0030] The spoke 2 includes a spoke body 21, a spoke inner ring 22 and a spoke outer ring 23. In this technology, the main structure of the spoke remains unchanged, and the improvement is only provided on the inner surface of the spoke inner ring and the outer surface of the spoke outer ring. Axial grooves or protrusions are used to increase the contact area with the matching interlayer to preven...

Abstract

The invention relates to an automobile low-noise tire. The automobile low-noise tire comprises a wheel core, a spoke, a rim and a tire skin, the spoke comprises a spoke body, a spoke inner ring and a spoke outer ring; the wheel core is arranged in the spoke inner ring, the two wheel rings are arranged on the spoke outer ring in a sleeving mode, and the tire leather is arranged in a groove formed by the spoke outer ring and the two wheel rings in a sleeving mode. A first interlayer is arranged between the outer surface of the wheel core and the inner surface of the spoke inner ring, and a second interlayer is arranged between the outer surface of the spoke outer ring and the inner surface of the wheel rim. The low-noise tire is simple in structure and reliable in performance, two-stage rubber vibration isolation is formed through a rubber layer structure between the rim and the spoke and a rubber layer structure between the spoke and the wheel core, vibration transmitted to the wheel core from a road surface can be effectively attenuated, and therefore the effect of reducing automobile road noise is achieved.

Description

technical field [0001] The invention belongs to the technical field of tires, in particular to an automobile low-noise tire. Background technique [0002] With the improvement of consumers' requirements for automobile comfort, automobile manufacturers put more research effort into improving the NVH characteristics of automobiles. The noise caused by road excitation (referred to as road noise) is a type of noise that customers complain about most at present. Especially for pure electric vehicles, due to the decrease in the proportion of powertrain noise, the problem of road noise in vehicles is more prominent. [0003] Tire noise is the main source of road noise. In order to control tire noise, it is necessary to optimize the NVH performance of tires during vehicle development to ensure that tires can better attenuate the excitation from the road surface. [0004] There are three main ways to optimize tire noise. One is to optimize the tire pattern structure, the other is to...
