An inner support body of a safety tire

Abstract

The invention discloses an inner support body of a safety tire, which comprises an inner ring, a metal ring and a buffer ring which are orderly arranged along the direction from a hub steel ring to an outer tire. The outer ring surface of the metal ring is provided with a buffer ring installing groove and a buffer ring limiting groove, the inner ring surface of the buffer ring is provided with a limiting rim and a limiting platform, the limiting rim is correspondingly embedded in the buffer ring installing groove on the outer ring surface of the metal ring, the lifting platform is correspondingly embedded in the buffer ring limiting groove on the outer ring surface of the metal ring, the relative sliding of the buffer ring and the metal ring is limited, and the outer ring surface of the buffer ring faces toward the inner surface of the outer tire. The inner support body of the safety tire, disclosed by the invention, can efficiently overcome and resolve suddenly increased friction caused by tire explosion so as to maintain the stable driving and the direction-controllable status of automobiles, thereby avoiding danger of sudden tire explosion of automobiles at high speed. In addition, the invention has advantages of reasonable design, production and assembly, simple installation, easy operation, reliable quality, enhanced practical applicability and potential replication of the product.

Description

technical field [0001] The invention relates to an automobile safety insurance device, in particular to an inner support body of a safety tire and a method for installing the safety tire. Background technique [0002] At present, in order to prevent car tires from getting out of control or even overturning after a puncture, the safety device is to install additional wheels processed with different materials on the wheel hub steel rim of the vehicle. The purpose is to make the attached wheels play a role in supporting the tires , Try to avoid greater dangers and accidents, and enable the vehicle to continue to travel for a certain distance. This safety device is also known as tire inner support body technology. Several tire safety devices made of high-strength engineering plastics are disclosed in existing patents, such as Chinese patent ZL96219610. Attached wheels, when the tire is blown out, the attached wheels support the car body to continue sliding to ensure safety. I...

AI Technical Summary

Problems solved by technology

[0003] There are many defects in the implementation process of the existing tire inner support body technology, which are mainly manifested in: 1. Due to the different tire crown heights of different brands and models, it is necessary to manufacture the entire inner support body according to the actual size, so in actual use 2. The inner support body in the prior art cannot effectively overcome the impact load caused by the sudden tire burst of the vehicle at high speed, which directly leads to the damage of the wheel hub steel ring, and the vehicle cannot Keep driving, even lose control and capsize
