The rim, the retainer ring, the lock ring and the sealing ring are tightly attached, the locking force is strong, stronger tire air pressure is provided, the sealing ring cannot be installed after the lock ring is reversely installed, and the locking accident of the lock ring is avoided.)

1. A multi-piece tubeless wheel characterized in that: the wheel rim comprises a wheel rim, a check ring, a locking ring and a sealing ring, wherein a sealing groove and a locking groove are sequentially formed in the upper edge of a mounting surface at one end of the wheel rim along the end face, the check ring is of a bent structure with one section contacting the wheel rim and the other section tilting away from the wheel rim, a bulge is arranged behind the position of the sealing groove on the section of the check ring contacting the wheel rim, the edge of the locking groove of the check ring tilts to form a tilting section which is a curved surface, an installation inclined plane is arranged at the tilting position of the check ring, the locking ring is of a 7-shaped structure comprising a locking section and a locking section, the locking section is arranged in the locking groove, the locking section is attached to the surface of the wheel rim outside the locking groove, the bending surface of the locking ring attached to the locking groove is the front surface of the locking ring, the locking ring bending surface opposite to the front surface of the locking ring is the back surface of the locking ring, the locking ring bending position on the back surface is provided, Is compressed by a retainer ring by a certain amount.

2. The multi-piece tubeless wheel of claim 1 wherein: the end face diameters of the locking section and the locking section are the same.

3. The multi-piece tubeless wheel of claim 2 wherein: the length of the locking section is more than or equal to 1.5 times of the diameter of the end face of the locking section.

Technical Field

The invention relates to the technical field of wheels, in particular to a multi-piece type tubeless wheel.

Background

Many formula tubeless wheel generally comprises rim, retaining ring and lock ring, and shape and specification and the mutual scheme of joining in marriage through design three are up to standard in order to reach tire installation and wheel pressure-bearing, but the condition that the lock ring dress is anti-can appear in the installation, when causing the locking force that pneumatic pressure accumulated to a certain extent and is greater than the lock ring, can produce the blasting, lead to lock ring, retaining ring, tire departure from the rim even, can lead to the casualties accident when serious.

Disclosure of Invention

The invention aims to provide a multi-piece tubeless wheel with a special shape and structure, and aims to solve the problems of insufficient locking force and reverse installation of a locking ring.

The invention is realized by the following steps: a multi-piece tubeless wheel comprises a rim, a check ring, a locking ring and a sealing ring, wherein a sealing groove and a locking groove are sequentially formed in the upper edge of a mounting surface at one end of the rim, the check ring is of a bending structure which is in contact with the rim and is tilted away from the rim, a bulge is arranged behind the position of the sealing groove on the contact section of the check ring and the rim, the edge of the locking groove of the check ring is tilted to form a tilted section which is a curved surface, an installation inclined plane is arranged at the tilted position of the check ring, the locking ring is of a 7-shaped structure comprising a locking section and a locking section, the locking section is installed in the locking groove, the locking section is attached to the surface of the rim outside the locking groove, the reverse side bending surface of the locking ring, which is attached to the locking groove, is the front side of the locking ring, the opposite locking ring bending surface of the front side of the locking ring is the locking ring, the locking ring bending position of the locking ring is provided with a locking ring inclined plane, the sealing ring is arranged in the sealing groove and is extruded by the retainer ring to have a certain compression amount.

The further technical scheme of the invention is as follows: the end face diameters of the locking section and the locking section are the same.

The further technical scheme of the invention is as follows: the length of the locking section is more than or equal to 1.5 times of the diameter of the end face of the locking section.

The invention has the beneficial effects that: the rim, the retainer ring, the lock ring and the sealing ring are tightly attached, the locking force is strong, stronger tire air pressure is provided, the sealing ring cannot be installed after the lock ring is reversely installed, and the locking accident of the lock ring is avoided.
