Support ring for internal support of tire

Abstract

The invention discloses a support ring for inner support of a tire. The support ring is of an annular structure formed by mutually matching and assembling four support units, the top of each support unit is provided with a support surface, the top of each support unit converges towards the bottom, the convergent part is a support part, and one side, far away from the support surface, of the support part is provided with a contact surface. The support ring can play a role in run-flat protection after a tire is broken, so that it is guaranteed that a vehicle is not out of control, necessary tirereplacement is conducted after the vehicle safely runs to a reasonable position, meanwhile, the support ring can meet the run-flat protection requirements of all passenger vehicles, installation is easy and convenient, the adaptive capacity is high, and a traditional tire production process is not affected.

Description

technical field [0001] The invention relates to the fields of tires and supports, and more particularly relates to a bracket ring used for inner support of tires. Background technique [0002] Existing run-flat tires adopted the following forms, and the deficiencies of various forms are enumerated as follows: [0003] Thick-walled sidewall tires: In the inflated state, the impact resistance is poor, the comfort is poor, the tire is heavy, and the rolling resistance data is large. It is difficult to reach the safety limit for large specifications. The production requires special processes and specific equipment, which is very complicated and inefficient; Supporting and fixing brackets: Affect tire installation, poor ability to adapt to different tire section heights, high cost for the overall structure to carry a large load, excessive friction with the tire wall, easy to cause early damage, and replacement is very difficult, usually only the entire tire can be replaced, The ...

AI Technical Summary

Problems solved by technology

In this solution, the support surface is used to support the inner wall of the tire shoulder, the contact surface is used to fit and fix the inner surface of the tire bead, and the support part is used for the contact between the support surface and the contact surface. Force transmission; the inner surface of the tire bead is equipped with a bracket ring, and the bracket unit is processed in equal parts of the circumference, which solves the problem of fine-tuning the circumference and symmetrical balance quality; and because the bracket unit is split and independent, it does not affect The production and efficiency of the tires are only assembled with each other before use, which solves the problems of complex and difficult production of run-flat tires, low efficiency, and high cost; and overcomes the problem that large-sized tires cannot meet international standards for run-flat tires , really solve the run-flat of all passenger vehicle tires after leaking; the contact surface of the support unit designed for the same tire size is the same, because the current inner surface of the bead is in this small arc under the same tire size It is almost the same, so the adaptability of the contact surface will be greatly enhanced, that is, one or two kinds of bracket rings can be selected for the same tire size (the height of the bracket is different)
