Description

A tire and its bracket ring, bracket ring connection structure and installation method

technical field

The invention relates to the technical field of tires, in particular to a tire. In addition, the invention also relates to a bracket ring and a bracket ring connection structure and installation method.

Background technique

Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Usually installed on metal rims, it can support the body, buffer external impact, realize contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used for tire production, which shows the ability of tires to consume rubber.

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 maintenance cost is too high, and it is also easy to cause friction and collision with other parts inside the tire, or even break; the inner wall leak-proof glue spraying method: the sidewall cannot be effectively protected, and the size of the protective hole is limited, so it is not easy to spray evenly , making it very complicated and inefficient.

Currently, run-flat tires generally have the characteristics of being heavy, requiring additional components or using special wheels, which increases the unsprung mass of the vehicle and affects the handling performance of the vehicle. When the tires are used to the point of replacement, the price of run-flat tires will also be higher than that of ordinary tires. And the run-flat tire of some structure can't be repaired after damage, can only change, and maintenance cost is increased. Due to the thickening of the tire wall, the shock absorption effect of the tire is reduced, and in severe cases, the wheel hub will be deformed.

The application number is: CN201721139020.2, and the publication number is: CN207257267U. The utility model patent discloses a comfortable and safe run-flat tire with a simplified process. Through a new type of sidewall mouth shape design, it can reduce the risk of running-flat tires. Production complexity, thereby improving production efficiency and uniformity; design the transverse groove as a gradual turbulent flow groove, disrupt the airflow entering the horizontal groove through the oblique section, and then discharge the turbulent airflow through the flared open groove bottom, which can Effectively reduce the high-pressure squealing sound, thereby improving the comfort of the tire; design the position of the upper and lower end points of the support rubber so that its width is conducive to covering the area with a large force, and at the same time, according to the linear relationship between the thickness of the tire support rubber and the temperature, the tire The support rubber is balanced in force, which is conducive to improving the durability of the tire at zero air pressure. It can run for 100 minutes at 80km/h, ensuring the safety performance of the run-flat tire.

The application number is: CN202010002557.4, and the invention patent with the publication number CN110949067A discloses a bracket ring for tire inner support. The bracket ring is assembled by four bracket units to form a ring structure. The bracket unit The top has a support surface, the top of the bracket unit converges toward the bottom, the convergent part is a support part, and the side of the support part away from the support surface has a contact surface. The bracket ring can function as a run-flat protection after a tire is leaked, so as to ensure that the vehicle does not lose control, and can safely drive to a reasonable position before performing necessary tire replacement. At the same time, it is applicable to the run-flat protection of all passenger vehicles Requirements, simple and convenient installation, strong adaptability, does not affect the traditional tire production process.
