Damping and noise-reducing solid tire and preparation method thereof

Abstract

The invention discloses a damping and noise-reducing solid tire and a preparation method thereof, and relates to the technical field of damping and noise-reducing solid tires. Center pattern blocks (8), side pattern blocks (10) and filling pattern blocks (11) are regularly distributed on a tread (2) of the tire body (1), side holes (13) are circumferentially distributed in the second tire side area (4) with the center line of the tire body (1) as the axis, the side holes (13) are inclined taper holes, and open hole circles exposed on the tire side are small circles of the side holes (13). Compared with the prior art, the solid tire has the beneficial effects that the method of adding the hollow inorganic particles into the polyurethane material of the solid tire and improving the structureof the solid tire is adopted, the tread is provided with the pattern blocks, the tire side wall is provided with the side holes, the vibration of the solid tire can be effectively reduced, and the noise is reduced by 2-8 dB.

Description

technical field [0001] The invention relates to the technical field of shock-absorbing and noise-reducing solid tires, in particular to a shock-absorbing and noise-reducing solid tire and a preparation method thereof. Background technique [0002] At present, urban noise pollution has become one of the four major environmental hazards. Among them, vehicle noise is the main source of urban noise. Reducing the noise of tires during driving has become one of the directions for tire improvement. [0003] A solid tire is a type of tire corresponding to a pneumatic tire (hollow tire). Its carcass is solid and does not use cords as a skeleton. Solid tires are mainly suitable for low-speed, heavy-duty vehicles; because solid tires do not cause tire blowouts or air leakage, they are widely used in mineral mining, engineering construction, and cargo transportation. Vehicles such as sprinklers and sweepers that operate at medium and low speeds on urban roads have begun to promote th...

AI Technical Summary

Problems solved by technology

[0005] Since the carcass of the solid tire is solid, when subjected to external vibration, the solid tire will almost completely transmit the vibration force to the car body itself, causing a large vibration and bump of the car body, that is, the shockproof performance of the solid tire is not good. Tire radiation noise is mainly caused by the vibration of the surrounding air caused by the vibration of the tire surface. The poor shockproof performance of solid tires leads to relatively large tire radiation noise.

And for the driver on a vehicle with solid tires, the ride comfort is not good
