Description

Technical Field

[0001] This utility model relates to the field of rubber tire technology, and in particular to a low-noise rubber tire. Background Technology

[0002] Noise-reducing tires, also known as low-noise tires, are designed specifically to reduce driving noise. These tires are very popular in certain usage scenarios, especially in cities and residential areas, where vehicle noise can have a significant impact on the living environment. As the only component of a car that directly contacts the road surface, its design directly affects the vehicle's driving performance, especially the noise generated during driving. Tire noise mainly comes from two aspects: one is the friction noise generated when the tire tread contacts the road surface, and the other is the cavity resonance generated by the airflow inside the tire. Utility Model Content

[0003] In order to overcome the above-mentioned defects in the prior art, the present invention provides a low-noise rubber tire.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a low-noise rubber tire, including a tire body, a set of tire sidewalls on each of the left and right sides of the tire body, a first support layer connected to the lower end of the tire body, a set of annular tubular portions on each of the left and right sides of the lower end of the first support layer, a second support layer connected to the lower ends of the two sets of annular tubular portions, a support rubber portion fixedly connected to the inner middle of the second support layer, a buffer layer fixedly connected to the upper end of the support rubber portion, and a sound-absorbing material filled between the upper end of the buffer layer and the first support layer.

[0005] Furthermore, the outer side of the annular tubular portion contacts the inner side of the tire side to provide support for the tire side, and the inner cavity of the annular tubular portion is filled with a filling portion.

[0006] Furthermore, an inner rubber body is provided between the annular tubular portion and the second support layer on the tire sidewall.

[0007] Furthermore, a connecting rubber part is fixedly connected to the outer side of the supporting rubber part, and the outer side of the connecting rubber part is fixedly connected to the second supporting layer.

[0008] Furthermore, the upper end of the tire body is provided with a tread pattern, which is used for anti-slip purposes.

[0009] Furthermore, a triangular rubber strip is provided at the lower end of the tire sidewall.

[0010] The beneficial effects of this utility model are: the first support layer supports the tire body outward, and the annular tubular part supports the tire sidewall outward, thereby enhancing the overall strength of the tire. The second support layer connects the rubber part and supports the buffer layer. Furthermore, sound-absorbing material is filled between the upper end of the buffer layer and the first support layer, which enhances the tire body structure while providing sound insulation and noise reduction, reducing noise during tire operation, and preserving the tire's own elasticity to ensure comfort during use.
