An all-steel radial tire belt drum and a method for laminating crown materials

Abstract

This application relates to the field of tire manufacturing, and discloses an all-steel radial tire belt drum and a method for laminating tire crown materials, wherein the all-steel radial tire belt drum includes: a drum shaft and a drum shaft arranged radially outside the drum shaft Drum plate, the side of the drum plate away from the drum shaft is used to support the material to be bonded; the side of the drum plate away from the drum shaft has a plane state and an arc surface state, and in the plane state, The belt drum is configured to attach the first belt layer with a preset angle to the tire circumference to the tire to be processed, and in the camber state, the belt drum is configured to be used to Process the second belt layer that fits the tire at zero degrees with the tire circumferential direction. The all-steel radial tire belt drum of the present application can utilize drum surfaces of different shapes to fit belt layers distributed in different angles or azimuths, which can improve the tension distribution of the belt layer, thereby improving the impact of the crown on the ground during the use of the tire. Force distribution, thereby improving the safety performance and service life of the tire.

Description

technical field [0001] The application relates to the field of tire manufacturing, in particular to an all-steel radial tire belt drum and a method for laminating crown materials. Background technique [0002] Tires are circular elastic rubber products assembled on vehicles or various machinery for rolling on the ground. They are usually installed on metal rims to support the body, buffer external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle. . With the development of the transportation industry, the tire industry is also constantly innovating. Wide driving surface and low aspect ratio tires have been continuously developed. Wide driving surface and low aspect ratio tires can replace the original twin tires. Compared with twin tires, the weight is reduced, making the car The oil consumption and emission decrease synchronously, it is environmentally friendly, and has the advantages of low manufacturing cost and low use cost...

AI Technical Summary

Problems solved by technology

However, the gap between the tire shoulder and the center of the crown of the tire with a wide running surface and low aspect ratio is relatively large. In the related art, the flat drum belt drum is used to bond the belt layer, and the crown ground contact mark of the manufactured tire is butterfly-shaped, that is, There are problems of uneven ground contact force and stress concentration on the crown, which have a blow to the safety performance and service life of the tire
