Rim and rubber ring connecting structure of wheel with parallel double tires

Abstract

The invention discloses a rim and rubber ring connecting structure of a wheel with parallel double tires. The rim and rubber ring connecting structure comprises rims of two tires which are arranged in parallel, wherein a rubber ring is arranged between the two rims, and the rubber ring is in interference fit with the axial direction of the rims. The interference fit between the rims and the rubber ring can effectively prevent stone and mud from being clamped and blocked between the double tires, so as to protect tire sidewalls from being punctured and pierced. The rubber ring achieves double axial clamping with the tires and the rims, so as to effectively prevent the wear and tear of the tires and own inner diameters caused by vertical drifting of the rubber ring due to the influence of tire pressure. The oil-saving performance is good. Holes are drilled at equal intervals along the circumference at the matching parts of the rubber ring and the tires to form lightening holes, so that materials are reduced, the balance weight of a vehicle model is reduced, and the purpose of saving oil is achieved. The rim and rubber ring connecting structure disclosed by the invention is especially suitable for being used on a wheeled excavator vehicle model with parallel double tires.

Description

technical field [0001] The invention belongs to the technical field of tires, and in particular relates to a connection design between a wheel rim and a rubber ring on a wheel with twin tires assembled together. Background technique [0002] The twin tires are mounted on the wheel, and the rim and the rubber ring are positioned in the center of the rim, and the sidewall is axially clamped and connected. The connection method is limited to the curve of the rim web. It is necessary to consider the alignment of the center of the rubber ring and the rim, and the matching gap between the two should not be too large. The design of the rubber ring should match the curve of the rim as much as possible to increase the contact of the mating surface. area. The change of the sidewall air pressure will affect the fixing of the rubber ring, especially in the case of insufficient air pressure, the rubber ring will move in the radial direction of the rim under the action of external force,...

AI Technical Summary

Problems solved by technology

The change of sidewall air pressure will affect the fixing of the rubber ring, especially in the case of insufficient air pressure, the rubber ring will move in the radial direction of the rim under the action of external force, so that the rubber ring and the rim, rubber Different degrees of friction between the ring and the tire will affect the service life of the tire and the rubber ring
