Tubeless vehicle wheel rim of removable wheel flange and tubeless vehicle wheel

Abstract

The invention provides a tubeless vehicle wheel rim of a removable wheel flange and a tubeless vehicle wheel. The tubeless vehicle wheel rim of the removable wheel flange and the tubeless vehicle wheel comprise a wheel rim main body and annular wheel flanges which are located on two sides of the wheel rim main body. Each annular wheel flange comprises a fixed flange and a movable flange, wherein the fixed flange is located on one side of the wheel rim main body, and the movable flange is located on the other side of the wheel rim main body. The movable flange is connected with the wheel rim main body in a disassembly and assembly mode. A tire disassembly and assembly groove for disassembling and assembling tires is formed in the middle along the periphery of the wheel rim main body, wherein the tire disassembly and assembly groove and the periphery surface of the wheel rim main body between the fixed flange form a first tire ring seat, and a second tire ring seat is formed by the tiredisassembly and assembly groove and the periphery surface of the wheel rim main body between the movable flange. The first tire ring seat is of a diverging form of a circular terrace from the fixed flange to the tire disassembly and assembly groove, and the second tire ring seat is of the diverging form of a circular terrace from the movable flange to the tire disassembly and assembly groove. Thetubeless vehicle wheel rim of the removable wheel flange and the tubeless vehicle wheel have the advantages that not only can the tires be prevented from releasing in the process of large load using,the safety reliability is improved, but also the using cost can be reduced, the service life of the tires can be prolonged and the removable wheel flange is good for environmental protection.

Description

technical field [0001] The invention relates to the field of auto parts manufacturing, in particular to a detachable rim tubeless wheel rim and tubeless wheel. Background technique [0002] As everyone knows, automobile wheels are generally divided into inner tube wheels and tubeless wheels according to the type of tires used. Among them, tubeless wheels have gradually been popularized and used due to their advantages in safety, energy saving, and environmental protection. According to statistics, the penetration rate of trucks in Europe and the United States and other countries using tubeless wheels has reached more than 95%, and the use of tubeless wheels in trucks in my country has reached 65%. above, with an increasing trend every year. [0003] However, the rim of the currently used tubeless wheel has low rim height and poor strength, so the rim of the tubeless wheel rim is prone to deformation when the road conditions are poor, the wheel bears a large load or turns, A...

AI Technical Summary

Problems solved by technology

However, in the actual use process, due to the high heat generated inside the wheel, the high pressure of the tire on the sealing ring, the oxidation of the rubber sealing ring by the gas in the tire and other harmful factors, especially the high temperature hazard caused by the superimposed use of high temperature weather in summer, the rubber sealing ring It is often damaged after a short period of use; and, because the sealing ring is easily deformed, the deformed or damaged sealing ring is attached to the tire bead at high temperature, resulting in deformation of the tire bead, and the deformed tire bead Early aging causes the service life of the tire to be shortened and it is difficult to disassemble; in addition, due to the limitation of the product structure, the gap between the tire and the wheel is small, and the thickness of the sealing ring is thin. One side of the ring is stressed, which accelerates the wear of the sealing ring

Therefore, it cannot be vigorously promoted and used in the market

[0006] In addition, there is a tubeless wheel in the prior art, which only strengthens the strength and thickness of the material. Although the deformation of the wheel is reduced, the reinforced wheel alleviates the failure of the wheel rim deformation to a certain extent during use. However, due to the low height of the rim of the tubeless wheel, when the wheel bears a large load or turns, or the road condition is poor, it will still cause failures such as tire prolapse and rim deformation. At the same time, the wheel rim structure cannot protect the tire. In the case of heavy load, it is easy to cause the sidewall of the tire to crack, which may cause a safety hazard in severe cases
