Embodiment Construction

[0030] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] An all-steel radial tire reinforced outside the bead, the tire includes a tire crown, a tire shoulder, a carcass cord layer 1, an inner liner layer 2, a belt layer and a tire bead. Such as figure 1 As shown, the bead includes a bead 7, an apex 3 and a spigot protector 4, the carcass ply 1 is turned up to the bead 7, and the two sides of the carcass 1 are respectively provided with steel cords. Cladding layer 5 and steel cord reinforcement layer 6. The steel cord turn-up layer 5 is fitted between the carcass ply 1 and the inner liner 2, the steel cord turn-up layer 5 bypasses the traveler 7 and has a U-shaped section, and the steel cord turn-up layer 5 Both the inner end point and the outer end point are higher than the turn-up end point of the carcass ply 1, the level difference between the outer end point of the steel c...

Abstract

The invention relates to an all-steel radial tyre for tyre bead external reinforcement. The tyre comprises a tyre crown, a tyre shoulder, a carcass ply, a belted layer and a tyre bead, wherein the tyre bead comprises wirecord rings, a bead filler and seam allowance protective colloid; the carcass ply de-envelops the steel wire rings; two sides of the carcass ply are respectively provided with a wirecord fabric de-enveloping layer and a wirecord fabric reinforcing layer; the wirecord fabric de-enveloping layer is attached between the carcass ply and an interlining layer; the wirecord fabric reinforcing layer is arranged between the carcass ply at the outer side of the tyre bead and the bead filler. According to the invention, through the improvement of the width of the wirecord reinforcing layer, the de-enveloped height of the outer side is increased greatly, so that the rigidity at the tyre bead is changed stably. Meanwhile, short steel ladles are additionally pasted on the inner side of the carcass ply, the high-load resistance of the tyre bead is intensified effectively; the durability and abrasion resistance of the tyre are improved; meanwhile, the oil consumption can be reduced effectively.

Description

technical field [0001] The invention relates to the field of manufacturing all-steel radial tires, in particular to an all-steel radial tire with an adjusted bead ladle structure and a preparation method thereof. Background technique [0002] With the rapid development of the automobile industry, the requirements for tire performance are getting higher and higher. Therefore, compared with bias tires, all-steel radial tires with good wear resistance and fuel economy have achieved rapid development and have become the tire industry mainstream products. However, bead problems during the running of all-steel radial tires will seriously affect the performance and service life of the tires, so the design and improvement of bead structures has become one of the key projects of major tire companies at home and abroad. The carcass cords of radial tires are radially arranged, and the sidewall is relatively soft. During the running of the tire, the bead is subjected to a large force, ...
