A kind of shock-absorbing and noise-reducing solid tire and preparation method thereof

Abstract

The invention discloses a shock-absorbing and noise-reducing solid tire and a preparation method thereof, and relates to the technical field of shock-absorbing and noise-reducing solid tires. On the tread (2) of the carcass (1), central pattern blocks (8), side pattern blocks (10) and filling pattern blocks (11) are regularly distributed, and on the second area (4) of the sidewall, the carcass The center line of (1) is the shaft circumference distribution side hole (13), and side hole (13) is the taper hole that slope is arranged, and the perforation circle exposed on the sidewall is the small circle of side hole (13). Compared with the prior art, the present invention has beneficial effects: the method of adding hollow inorganic particles to the polyurethane material of the solid tire and improving the structure of the solid tire is adopted, pattern blocks are arranged on the tread, and side holes are opened at the sidewall, It can effectively reduce the vibration of solid tires and reduce the noise by 2‑8dB.

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
