Problems solved by technology

[0005] The existing tire belt layer structure plays a sufficient role in ordinary tires, but in the all-steel radial tires that are constantly optimized and upgraded and are developing towards high flatness, the disadvantages of this structure are being reflected one by one
During the use of tires, sometimes there will be a phenomenon of voiding, that is, the phenomenon of separation between the tire belt layers, which will affect the service life of the tire and cause early damage

Embodiment Construction

[0019] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] image 3 , 4 Among them, the first belt layer 1, the second belt layer 2, the third belt layer 3, the fourth belt layer 4, the tread 5, the carcass 6, etc. are included.

[0021] Such as image 3 , 4 As shown, the present invention is a winding tire belt structure, including a carcass 6, on which at least a first belt layer 1 and a second belt layer 2 are sequentially attached, and the second belt layer The belt layer 2 includes three steel wires spirally wound on the first belt layer 1 and the rubber coating used to connect the three steel wires. During the winding process of the three steel wires, the gap between two adjacent coils of steel wires is 0~2mm. The angle between the wound steel wire and the center line of the tread 5 is 1°-3°, and the width of the second belt layer 2 is smaller than the width of the first belt layer ...

Abstract

The invention belongs to the field of tires and relates to a winding type tire belted layer structure. The winding type tire belted layer structure comprises a tire body, wherein a first belted layer and a second belted layer are sequentially fit and arranged on the tire body at least, the second belted layer comprises three steel wires spirally wound on the first belted layer and coating used for connecting the three steel wires, in a process of winding the three steel wires, a gap between two adjacent steel wire circles is 0-2mm, an included angle between the wound steel wires and a center line of a tire tread is 1-3 angles, and the second belted layer is narrower than the first belted layer. The winding type tire belted layer structure can be used for fundamentally solving circumferential deformation of a high flat tire in a using process and increase of stress among the belted layers due to creep deformation of crown center, and further thermogenesis at a crown part of a tire can be reduced, early damage phenomena such as void of the tire are avoided, and the service life of a high flat and wide running surface tire is prolonged.

Description

technical field [0001] The invention belongs to the field of tires and relates to a winding tire belt layer structure. Background technique [0002] At present, the development of the automobile industry and highways has put forward higher performance requirements for automobile tires. Safety, energy saving and environmental protection are the development direction of automobile tires today. The radial truck tires are developing in the direction of low rolling resistance, high durability and uniform wear resistance; at the same time, the low-cost, high-speed and high-stability tires pursued by customers now promote the tires to be flatter and wider. Face and tubeless development. [0003] The development and application of high flat, wide driving surface tires have gradually appeared some use limitations of this tire while improving some performance aspects. The tire belt is the main force-bearing part of the tubeless all-steel radial tire, and has special performance requ...
