Embodiment Construction

[0010] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0011] like figure 1 and figure 2 The semi-steel radial tire shown includes a tire body, the tire body has a tread layer 4, a sidewall layer 1 and an inner surface layer 2, and the inner surface layer 2 is a bead made by winding carbon fiber bundles; between the tread layer 4 and the inner surface layer Between the surface layers 2, there are crown belt strips 5 and skeleton layer 3 in sequence from outside to inside. The skeleton layer 3 is built with aramid fiber curtains, and aramid fiber cords are used instead of steel belt layers to reduce the weight of the tire. ; The tread layer 4 of the present embodiment adopts a rubber strip with the junction of the sidewall layer 1 and the cap strip 5 as the overlapping point and arranges it obliquely toward the other side of the cap strip 5. The end is lapped on the junction of the other side of the cap strip 5 and the ...

Abstract

The invention discloses a semi-steel radial tire and relates to the technical field of manufacturing of semi-steel radial tires. The semi-steel radial tire comprises a tire body; the tire body is provided with a tread layer, a sidewall layer and an inner face layer; a cap strip and a skeleton layer are arranged between the tread layer and the inner face layer in sequence from outside to inside; and the tread layer is formed by oblique piling arrangement of at least one rubber strip towards one side of the cap strip with the connection position of the sidewall layer and the other side of the cap strip as an overlapping point, the tail ends of the rubber strips are connected to the connection position of the cap strip and the sidewall layer in an overlapping mode, and the rubber strips arranged in an oblique piling mode are vulcanized into an integrated vulcanized tread layer. Compared with the prior art, the problem of the poor abrasion resistant strength of an existing tiny truck tirecan be solved.

Description

technical field [0001] The invention relates to the technical field of manufacturing semi-steel radial tires, in particular to a semi-steel radial tire for miniature trucks. Background technique [0002] Semi-steel radial tires have the advantages of energy saving, safety and durability. At present, most semi-steel radial tires are used for cars; many miniature trucks still use ordinary tires. Due to the limitations of load resistance, puncture resistance and impact blast resistance of ordinary tires, the wear resistance and tensile strength of the tire tread of miniature trucks are poor, and accidents are prone to occur during the load transportation process. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a semi-steel radial tire to solve the problem of poor wear resistance of the existing miniature truck tires. [0004] The technical solution adopted by the present invention to solve the technical problem is:...
