Description

Automobile vacuum wheel retainer ring

The technical field is as follows:

the utility model belongs to the technical field of the mobile device, concretely relates to car vacuum wheel retaining ring.

Background art:

the inventor develops and designs a vacuum wheel named as a twenty-two-point five-caliber vacuum wheel with a retaining ring, and as shown in fig. 3, the wheel comprises a wheel spoke plate and a rim 7, the wheel spoke plate and the rim 7 form an integrated structure from top to bottom, the retaining ring 5 is sleeved outside the rim 7, an annular groove is formed in the circumferential direction of the rim 7, and the groove is located on one side close to the wheel spoke plate. The main function of the retainer ring 5 in the vacuum wheel is to prevent the tire from being separated during the rotation running process. The matching between the conventional wheel retainer ring and the outer contour matching surface of the tire opening is not tight enough, so that the toe opening of the tire is worn under the condition of high air pressure or heavy load, the tire can be separated after the toe opening is worn for a long time, and serious potential safety hazards exist. In addition, the conventional wheel retainer ring causes the tire to be very inconvenient to disassemble and assemble, needs to be disassembled by using a special tool, and wastes time and labor. Therefore, it is very important to design the outer dimensions of the retainer ring for a vacuum wheel to improve the safety. Therefore, it is necessary to design a safe, reliable and conveniently-disassembled automobile vacuum wheel retainer ring.

The utility model has the following contents:

the utility model aims at providing a safe, reliable and convenient-to-disassemble automobile vacuum wheel retainer ring, which improves the safety of the retainer ring by designing the outer contour dimensions of the inner side and the outer side of the retainer ring, and the snap ring at the inner side can be firmly matched with a rim lock; the tightly-holding ring surface on the outer side of the tire can be tightly matched with the tire bead, the toe opening of the tire can be effectively prevented from being abraded, the phenomenon that the tire is separated under the running conditions of high air pressure and heavy load is avoided, the safety is improved, the tire is convenient to disassemble, the structural design is reasonable, and the tire is safe, reliable, convenient and practical and is easy to popularize and use on a large scale.

In order to solve the problem, the utility model adopts the following technical scheme: a vacuum wheel retainer ring for an automobile is characterized in that an L-shaped clamping groove ring which can be in clamping fit with a rim locking groove is arranged on the inner side of the retainer ring, and a V-shaped holding surface which can be in sealing fit with a tire bead opening is arranged on the outer side of the retainer ring; the circumferential included angle C between the top surface of the V-shaped clasping surface and the tire is 30-40 degrees, and the width B of the bottom surface of the V-shaped clasping surface is 8-18 mm; the length A of the L-shaped clamping groove ring is 5-15 mm.

Further, the circumferential included angle C between the top surface of the V-shaped enclasping surface and the tire is 35 degrees.

Further, the width B of the bottom surface of the V-shaped clasping surface is 13 mm.

Further, the length A of the L-shaped clamping groove ring is 10 mm.

Furthermore, the interface of the V-shaped clasping surface is in arc surface transition, and the interface of the L-shaped clamping groove ring is in arc surface transition.

The utility model has the advantages that: the automobile vacuum wheel retainer ring is safe, reliable and convenient to disassemble, the safety of the retainer ring is improved by designing the outer contour sizes of the inner side and the outer side of the retainer ring, and the snap ring on the inner side can be firmly locked and matched with a rim; the tightly-holding ring surface on the outer side of the tire can be tightly matched with the tire bead, the toe opening of the tire can be effectively prevented from being abraded, the phenomenon that the tire is separated under the running conditions of high air pressure and heavy load is avoided, the safety is improved, the tire is convenient to disassemble, the structural design is reasonable, the tire is safe and reliable, the service life of the tire is prolonged, and the tire is economical and applicable and easy to popularize and use on a large scale.
