Embodiment 1

[0012] like figure 1 and figure 2 As shown, a multi-piece tubeless wheel includes a rim 2, a retaining ring 1, a locking ring 3 and a sealing ring 4. A sealing groove and a locking groove are sequentially opened on the mounting surface at one end of the rim along the end surface. The retaining ring is a curved structure in which one section is in contact with the rim and the other is tilted away from the rim. There is a protrusion behind the sealing groove on the contacting section of the retaining ring, and the retaining ring is raised at the edge of the lock groove to form a curved surface. The cocked section, the retaining ring has an installation slope at the cocked part, the lock ring is a "7-shaped" structure including the locking section and the locking section, wherein the locking section is installed in the lock groove, and the locking section is attached to the Fitted on the rim surface outside the lock groove, the bending surface of the lock ring and the lock groo...

Embodiment 2

[0015] The diameters of the end surfaces of the locking section and the locking section are the same or similar, and the diameter difference is not more than 2 mm, and the length of the locking section is ≥ 1.5 times the diameter of the end surface of the locking section. The rest of the technical solutions are basically consistent with the first embodiment. Through the shape design and proportional control of the locking section and the locking section of the lock ring, the lowest consumables and the most convenient production under the same pressure are achieved.

Abstract

The invention relates to a multi-piece tubeless vehicle wheel. The multi-piece tubeless vehicle wheel comprises a rim, a retainer ring, a locking ring and a sealing ring, wherein a sealing groove anda locking groove are sequentially formed in an installing surface of one end of the rim along the end face, the retainer ring is a bending structure with one segment making contact with the rim and the other segment cocked and far away from the rim, the retainer ring has a protrusion behind the seal groove location on the contact segment with the rim, an installing inclined plane is arranged at the cocking part of the retainer ring, the locking ring comprises a "7"-shaped structure consisting a locking segment and a fastening segment, wherein the locking segment is installed in the locking groove, the fastening segment is attached to the rim surface outside the locking groove, a locking ring inclined surface is arranged at the bending position of the reverse side of the locking ring, the locking ring inclined surface is attached to the installing inclined plane, the length of the fastening segment is great than or equal to the distance between the sealing groove and the locking groove,and the sealing ring is installed in the sealing groove. The rim, the retainer ring, the locking ring and the sealing ring are tightly attached, the locking force is strong, stronger tire air pressure is provided, and the sealing ring cannot be installed after the locking ring is reversely installed, so that the locking ring reversely-installing accident is avoided.

Description

technical field [0001] The invention relates to the technical field of wheels, in particular to a multi-piece tubeless wheel. Background technique [0002] Multi-piece tubeless wheels are generally composed of rims, retaining rings and lock rings. By designing the shapes, specifications and mutual matching schemes of the three, the tire installation and wheel pressure compliance can be achieved. However, during the installation process, lock rings will appear In the opposite situation, when the inflation pressure accumulates to a certain extent greater than the locking force of the lock ring, it will explode, causing the lock ring, retaining ring, and even the tire to fly out of the rim, which will cause casualties in severe cases. Contents of the invention [0003] The purpose of the present invention is to provide a multi-piece tubeless wheel with a special shape and structure, aiming to solve the problems of insufficient locking force and reverse installation of the loc...
