Problems solved by technology

The carcass of the current thickened sidewall support structure tire is relatively hard. Compared with ordinary tires, this structure tire is heavier in weight and generally poor in comfort. It has higher requirements on the vehicle suspension system, and its application range is limited to some high-end models. , the penetration rate among the general public is low
And before the present invention, the tire with embedded support body structure in the tire known before the present invention is limited by the support body structure and material, and the heat generation is often higher, and it is mostly used in slow speed and low speed tires, which still cannot be solved in high-speed automobile tires. thermal damage, there are great application limitations

Embodiment Construction

[0017] The present invention will be further elaborated below in conjunction with the drawings and specific embodiments.

[0018] Such as Figure 1-2 As shown, an arched hollow inner support type safety tire includes tire casing 1, tread rubber 2, base rubber 3, cap layer 4, belt layer 5, sidewall 6, carcass ply 7, apex 8, The spigot rubber 9, the bead 10, the inner liner 11, the inner support 12, the outer tire 1 includes the tread rubber 2, the base rubber 3, the cap layer 4, the belt layer 5, and the carcass cord from the outside to the inside. 7. Airtight layer 11, the tire 1 is provided with sidewalls 6 on both sides, the inner ring of the sidewall 6 is provided with an apex 8, a spigot 9 and a bead 10, and the inner support body 12 is arched In a ring structure, the support body 12 is arranged inside the tire casing 1, and the support body 12 is not in contact with the inner liner 11 of the inner wall and outer ring of the tire casing 1.

[0019] The outer tire is a common ...

Abstract

The invention discloses an arch-shaped hollowed-out inner-supported safety tire, including an outer tire, tread rubber, base rubber, coronal band layer, coronal band layer, sidewall, carcass ply, gumtriangle, gum triangle, bead, airtight layer, inner support, the outer tire comprises tread rubber from the outside to the inside, A base rubber, a crown belt layer, a belt layer, a carcass ply, and an air-tight layer are arranged on both sides of the outer tire. The inner ring of the outer tire is provided with a triangular rubber, a sub-mouthpiece rubber, and a bead. The inner supporting body isof an actuate circular ring structure. The supporting body is arranged inside the outer tire, and does not contact with the air-tight layer of the outer ring of the inner wall of the outer tire. Theinner support body of the invention not only plays a supporting role but also plays a noise reduction role, and the protective role of the inner support is converted from air buffer to air + inner support buffer during impact, so that the tire is more durable.

Description

Technical field [0001] The invention relates to the field of tire manufacturing, in particular to an arched hollow inner support type safety tire. Background technique [0002] The currently known run-flat tires generally adopt a thickened sidewall support or a structure with a support body embedded in the tire. The carcass of the current thickened sidewall support structure tires is harder. Compared with ordinary tires, this structure tires are heavier in weight and generally less comfortable. It has higher requirements for vehicle suspension systems, and the scope of use is limited to some high-end models. , The penetration rate used by the general public is low. However, the tires with a support structure embedded in the tires known before the present invention tend to generate high heat due to the limitation of the support structure and materials. They are mostly used in slow and low-speed tires, but still cannot solve the problem of high-speed automobile tires. The thermal...
