Problems solved by technology
[0002] With the development and progress of the country, the application of all-steel radial tires for medium and long-distance trucks and buses is increasing, and the performance of the tread shoulder of the tires puts forward higher and updated requirements. Steel radial tires have the characteristics of high load and fast speed, etc. The stress concentration on the tread shoulder, excessive heat generation, and frequent problems such as shoulder voids
At the same time, due to the design, manufacturing or use problems of the tire itself, the abnormal wear of the tire shoulder is excessive, resulting in a decrease in the service life of the tire. It is difficult to determine the cause of such problems, so it is difficult to fundamentally solve them.

Embodiment Construction
[0012] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0013] Such as figure 1 As shown, the present invention is a shoulder wing structure of an all-steel radial tire. A plurality of grooves 2 are evenly distributed on the shoulder 1 wing in a circumferential shape. The grooves 2 form an acute angle with the vertical centerline of the tire. In practice, , the angle between the groove 2 and the vertical centerline of the tire is 30°~31°; the groove 2 includes an outer groove 2-1 and an inner groove 2-2.
[0014] The vertical distance between the upper end point of the notch of the groove 2 and the outer end point of the tire shoulder 1 is 5.5-6mm.
[0015] The notch width of the outer groove 2-1 is 5.5mm, the depth of the outer groove 2-1 is 8.5mm, and the width of the inner groove 2-2 is 2mm.
[0016] The lower notch of the outer groove 2-1 is a circular arc transition structure. When the tir...

Abstract
The invention belongs to the technical field of tire equipment, and relates to a shoulder part structure of an all-steel radial tyre. A plurality of grooves are formed in a tyre shoulder part in a circumference mode, and the grooves and the vertical center line of the tyre form an acute angle respectively; and the grooves include outer grooves and inner grooves. The shoulder part structure of theall-steel radial tyre solves the problems of concentrated stress and overlarge heat generation of the shoulder part of the all-steel radial tyre of a medium-long distance transport type truck, reducesthe problems of shoulder clearance and the like, prolongs the service life of the tyre, improves the safety performance of the tyre, and improves and reduces the condition of eccentric wear of the shoulder part of the tyre to a certain extent.

technical field [0001] The invention belongs to the technical field of tire equipment and relates to a shoulder wing structure of an all-steel radial tire. Background technique [0002] With the development and progress of the country, the application of all-steel radial tires for medium and long-distance trucks and buses is increasing, and the performance of the tread shoulder of the tires puts forward higher and updated requirements. Steel radial tires have the characteristics of high load and fast speed, etc. The stress concentration on the tread shoulder, excessive heat generation, and shoulder voids often occur. At the same time, due to the design, manufacturing or use problems of the tire itself, the abnormal wear of the tire shoulder is excessive, resulting in a decrease in the service life of the tire. It is difficult to determine the cause of such problems, so it is difficult to fundamentally solve them. Contents of the invention [0003] In view of the above pro...
