Problems solved by technology

[0004] For steel tubeless wheels, the ability to prevent puncture and puncture is strong, but the height of the rim at both ends of the rim is low, resulting in heavy load or uneven load, the tire is easy to come out of the wheel cylinder, so the bearing capacity is weak, Unsuitable for heavy-duty vehicles
In addition, there is a new type of tubeless wheel on the market that utilizes the existing inner tube wheel. The principle is to add a rubber sealing ring to the rim body, and use the sealing ring to block the air leakage link of the assembly part of the tire and the wheel. High temperature, high pressure, wading, oxidation, deformation and other factors cause the rubber sealing ring to be damaged in a short period of time, and due to space constraints, 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

Embodiment 1

[0029] Example 1, a new type of heavy-duty integrated tubeless wheel, the spoke and the rim are integrally formed by spinning, there is no welding seam on the rim and the joint between the rim and the spoke, and the whole wheel is made of a round cake through three spinning , two forgings and one rolling process, and the annular circlip 2 is made of strip-shaped steel; through integral spinning and rolling, the spokes of the wheel body 1 and the middle and lower parts of the rim body The outline of the rim body is fully formed, and the shape of the middle and lower part of the rim body is as follows: a partial circumferential depression 104 in the middle, which is used as a way to facilitate the insertion of the tire when loading the tire; and two opposite slopes are formed on both sides of the middle part—bead seat, tire The ring seat is a smooth slope with a certain inclination, and as the most important part for assembling with the tire, it can ensure that the tire and the w...

Embodiment 2

[0039] Embodiment 2, a new type of heavy-duty combined welding tubeless wheel, the spoke and the rim are welded together, the outer circle of the spoke is pressed and welded together with the inner wall of the annular rim 106 of the rim, and the weld is between the rim and the inner wall of the annular rim 106 At the junction of the spokes, the wheel as a whole is formed by welding the rim and the spokes through different processes, while the annular circlip 2 is rolled from strip-shaped steel; Give way, it is convenient to insert the tire when installing the tire; and two opposite slopes are formed on both sides of the middle part - the bead seat, the bead seat is a smooth slope with a certain slope, as the most important part of the tire assembly , can ensure that the assembly of the tire and the wheel main body 1 is tight without leakage.

[0040] The big end of the rim is partially forged to form an annular rim, which is used to limit the one-way axial displacement and det...

Abstract

The invention discloses a novel heavy load wheel without an inner tube. A wheel body is composed of an arc-shaped elastic baffle ring; the two sides of the middle of the wheel body are provided with two opposite and oblique tire bead seats, and a ring-shaped concave part is arranged between the two tire bead seats; an air door hole sinking platform is arranged in the ring-shaped concave part; thewheel further comprises an air door core which is used for assisting the wheel body. The wheel has the advantages that a tire without the inner tube can be assembled, the dismantling and assembling are extremely convenient, a wheel flange is higher, the function of preventing the releasing of the tire is achieved, and the wheel can be applied to a heavy loading vehicle.

Description

technical field [0001] The invention relates to the field of auto parts manufacturing, in particular to a novel heavy-duty tubeless wheel. Background technique [0002] Car wheels are generally divided into tubeless wheels and tubeless wheels according to the types of tires used. Among them, due to various advantages in environmental protection and use, the coverage of tubeless wheels in the market has completely surpassed that of tubeless wheels. [0003] The wheel cylinders of tubed wheels and steel tubeless wheels are welded by spokes and rims. There are many limitations in the production process and the product itself. The spokes and rims of the wheels come from two different raw materials, and after clamping, The process routes such as positioning are made separately, and finally assembled and welded. The manufacturing and production are divided into three production lines: spoke, rim and assembly. In addition, there are defects in the hot rolling, welding and grinding...
