Abstract

The invention discloses an industrial vehicle tire using a rubber reinforcing part on outside of a bead. The industrial vehicle tire comprises a tire body, a tire main cord fabric layer is arranged onthe inner wall of the tire body, and a tire main cord fabric layer turn-up part is arranged at the edge of the tire main cord fabric layer; a tire bead filler, a steel wire ring and a tire bead constraint reinforcing part are arranged on the inner side of the tire main cord fabric turn-up part, the tire bead constraint reinforcing part is spirally wound on the steel wire ring in a wrapping mode,a reinforcing assembly is arranged on the outer side wall of the tire main cord fabric turn-up part, and the part, making contact with the ground, of the tire body is a tire crown. The inner wall of the tire crown is provided with a belt beam layer assembly. According to the industrial vehicle tire, the thickness of the tire bead filler is moderate, secondary molding is not hindered, the quality control cost in the production and storage processes of parts and the manufacturing process of a green tire can be reduced, and the crescent-shaped rubber reinforcing part is added to the outer side ofthe turn-up part of the main cord fabric layer of the tire. The hardness is higher than that of sidewall rubber and the heat generation is lower than that of the sidewall rubber, so that the bead part heat generation problem can be controlled.

Description

technical field

[0001] The invention relates to the technical field of vehicle tires, in particular to an industrial vehicle tire with rubber reinforcements on the outside of the bead. Background technique

[0002] The existing industrial wheel tires used for lift trucks, airport luggage tractors or light rail vehicles are limited by the width of the rim seat and the width of the traveler required by high inflation pressure, usually only rely on the turn-up part of the main ply of the tire and the The bead filler absorbs and buffers the tension of the main ply of the tire when the tire is loaded, and no additional reinforcement structure is provided. Use thicker, harder bead fillers. There are also manufacturers who attempt to adjust the material arrangement of the bead filler and sidewall rubber, trying to make the turnup of the main ply of the tire be at the neutral axis of bead bending deformation, and reduce the bead delamination caused by bead strain. Thicker and hard...
