High-rim section steel tubeless vehicle wheel without sealing ring and weld joint

Abstract

The invention provides a high-rim section steel tubeless vehicle wheel without a sealing ring and a weld joint. The high-rim section steel tubeless vehicle wheel is composed of a wheel body, an annular elastic retainer ring and a valve core, wherein an annular deep groove is formed in the middle of a rim, two bead seats are symmetrically arranged in the annular deep groove, a plane structure is upset at the inclined plane between the annular deep groove and one of the bead seats, and a valve hole is punched in the center of the plane structure; the valve core is assembled on the valve hole. According to the high-rim section steel tubeless vehicle wheel, since spokes and a rim body are integrally formed, the welding difficulty and the overall strength defect are overcome, the technologicalprocess of wheel manufacturing and production management are simplified, the wheel is convenient to disassemble and high in rime, and thus the axial displacement and disengagement of a tire are effectively limited.

Description

technical field [0001] The invention relates to the field of auto parts manufacturing, in particular to a high rim steel tubeless wheel without a sealing ring. Background technique [0002] Due to the various advantages of environmental protection and use, the use coverage of tubeless wheels in the market has completely surpassed that of tubeless wheels. Tubeless tires are more wear-resistant than tubeless tires. Will be affected by the heat of the brake drum. It has no inner tube and cushion belt, and uses the inner wall of the tire and the airtight layer of the bead to ensure good air tightness between the tire and the rim, and the outer tire also plays the role of the inner tube. The tire and the wheel rim are sealed as a whole. When the vehicle is running at high speed, the high temperature generated by the friction between the tire and the road surface will be directly dissipated through the steel ring inside to quickly reduce the tire temperature, thereby prolonging t...

AI Technical Summary

Problems solved by technology

However, trucks cannot meet the requirements of installing tubeless tires due to their large load capacity and harsh driving conditions.

As for tire wheels, most trucks currently use steel wheels with inner tubes, and the poor performance of the wheel system is an important reason for vicious traffic accidents. Common high-speed tire blowouts of trucks all occur on wheels with inner tubes.

[0004] At present, the tubeless wheels that have been remanufactured from inner tube wheels use sealing rings to block the air leakage link of the tire and wheel assembly parts. , the thickness of the sealing ring is thin, and it is easy to deviate during installation, resulting in unilateral force on the sealing ring and accelerated wear
