Short tire crown three-section type inner supporter of safety tire

Abstract

The invention discloses a short tire crown three-section type inner supporter of a safety tire; the supporter comprises an inner ring and an outer ring; the outer ring is rotationally arranged on the ring surface of the outer side of the inner ring; the ring surface of the inner side of the inner ring embraces on a hub steel ring; the inner ring is provided with a fracture; an annular lug boss is arranged on the ring surface of the outer side of the inner ring; the outer ring is of three-section type; both ends of each outer ring section are provided with female and male connections; the three outer ring sections are locked into the ring through the male and female connections by a connector; each outer ring section consists of a metal ring and a buffer ring; the ring surface of the inner side of the metal ring is provided with a groove matched with the annular lug boss on the ring surface of the outer side of the inner ring, and the ring surface of the inner side embraces on the ring surface of the outer side of the inner ring; the ring surface of the outer side of the metal ring is provided with an annular groove; the ring surface of the inner side of the buffer ring is provided with an annular bulge matched with the annular groove on the ring surface of the outer side of the metal ring; and the ring surface of the inner side of the buffer ring is embedded on the ring surface of the outer side of the metal ring. By adopting the structure, the supporter is easy to mount, and the property of bearing impact load during tire burst is enhanced.

Description

technical field [0001] The invention relates to an automobile safety insurance device, in particular to a short crown three-lobed inner support body of a 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. It includes a vacuum t...

AI Technical Summary

Problems solved by technology

[0003] The existing inner support body technology of the tire is because the inner support body ring is a whole, in the process of implementation, especially for civilian cars with short crown tires, the existing inner support body is not conducive to installation

The inner support body will be deformed when it is impacted when the tire is blown out, and the inner support body cannot roll freely on the wheel rim. If it is slight, the car will deflect, and if it is serious, it will cause heavy casualties.
