Description

Technical Field

[0001] The utility model relates to the technical field of wheels, in particular to an air leakage-proof wheel assembly structure. Background Art

[0002] As people's living standards continue to improve, the number of cars per capita continues to increase, the number of vehicles on the road is gradually increasing, and traffic accidents are also increasing. Tires are ground-contacting and rolling annular elastic rubber products installed on various vehicles or machinery. They are usually installed on metal rims, which can support the vehicle body, buffer external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects when driving. Tires usually have valves installed on the sidewalls or toe mouths, but the valves are mostly fastened to the installation position by nuts. The disadvantage of this structure is that it often leaks and needs to be improved.

[0003] Therefore, it is necessary to provide a new anti-leakage wheel assembly structure to solve the above-mentioned technical problems. Utility Model Content

A fixing hole is opened on the outer surface of the rim. One end of the valve stem is inserted into the fixing hole, and both sides of the support wheel are respectively attached to one side of the retaining ring.

[0009] Furthermore, the support wheel is composed of a decorative steel ring and a connecting horizontal axis. There are two groups of decorative steel rings, which are symmetrically arranged. The two ends of the connecting horizontal axis are respectively inserted into the grooves on one side of the two groups of decorative steel rings.

[0010] Furthermore, the two groups of decorative steel rings are composed of supporting steel columns and supporting steel plates. Multiple groups of supporting steel columns are arranged at intervals along the inner circumference of the rim, and supporting steel plates are fixedly connected between the multiple groups of supporting steel columns. A mounting groove is opened on one side of the supporting steel plate.

[0011] Furthermore, a rubber layer is provided on the outer surface of the wheel rim, and the rubber layer of the wheel rim is attached to the outer surface of the rubber layer on one side of the tire.

[0012] Furthermore, the vertical distance between the inner peripheral contact surface of the wheel rim and the center line of the air inlet end of the valve is 15-50 mm.

A memory rubber layer corresponding to the inner tube is provided on the inner wall of the outer tire, and the memory rubber layer is flexibly connected to the outer tire and the inner tube respectively. When the tire is pierced by a nail, the memory rubber layer is used to block the shorter nail, which prevents the shorter nail from piercing the inner tube to a certain extent. When the nail is taken out, the memory rubber layer will slowly return to its original state to continue to protect the inner tube.

[0015] 2. The two groups of decorative steel rims are respectively fitted on one side of the baffle fixed to the wheel rim, and the two ends of the connecting horizontal axis are respectively inserted into the grooves on one side of the two groups of decorative steel rims.
