Embodiment

[0026] Please refer to Figure 1-Figure 5 , the present embodiment provides a support type run-flat tire, comprising an airtight layer 10 and a carcass layer 11, the outer side of the innerliner layer 10 is bonded to the inner side of the carcass layer 11 at the tread, and the innerliner layer 10 is laid with support rubber 20 on the sidewall and shoulder, and the inner side of the ply 11 is attached to the outer surface of the support rubber 20 at the sidewall and shoulder. The cross section of the support rubber 20 in the radial direction is crescent-shaped.

[0027] By setting support rubber at the sidewall and shoulder between the airtight layer and the carcass layer, the tire can be effectively supported, and the support performance of the tire at low or zero pressure caused by air leakage or blowout can be improved to prevent the tire from being overwhelmed. Deformation enables the car to run normally, and further optimizes its mechanical properties by setting its radial...

Abstract

The invention discloses a supporting type run-flat tire, which belongs to the technical field of tires, and comprises an airtight layer and a cord fabric layer, wherein the outer side of the airtight layer and the inner side of the cord fabric layer are attached to a tread, supporting rubber is laid on the outer side of the airtight layer and on a tire side and a tire shoulder, and the inner side of the cord fabric layer is attached to the outer surface of the supporting rubber on the tire side and the tire shoulder. The radial section of the supporting rubber is in a crescent shape. The supporting rubber is arranged between the airtight layer and the cord fabric layer and located on the tire side wall and the tire shoulder, the tire is effectively supported, the supporting performance of the tire in the low-pressure or zero-pressure state caused by air leakage or tire burst is effectively improved, the radial section of the tire is further arranged to be in a crescent shape, the mechanical property of the tire is optimized, the tire shoulder and the tire side wall of the tire are effectively reinforced, and the overall deflection and the load of the tire are increased.

Description

technical field [0001] The application belongs to the technical field of tires, in particular to a support type run-flat tire. Background technique [0002] Supported run-flat tires refer to tires that can still run stably for a long time or temporarily after a flat tire. Equipped with a spare tire to reduce the weight of the vehicle and reduce manufacturing costs. However, the overall support performance of the existing support type run-flat tires is still not ideal, especially the long-term normal operation of the vehicle cannot be guaranteed under the situation of low air pressure or 0 air pressure; The phenomenon of sidewall breaking seriously affects the overall life of the tire and driving safety. Contents of the invention [0003] The purpose of this application is to provide a supported run-flat tire, which solves the technical problem of unsatisfactory tire support performance in the case of low air pressure or zero air pressure in the prior art, thereby increas...
