Description

Vacuum tire steel ring with simple structure

Technical Field

The utility model belongs to the technical field of the vacuum tire steel ring, especially, relate to a simple structure's vacuum tire steel ring.

Background

In the matching of tires of various trucks and engineering vehicles, wheel steel rings are divided into two types of tubeless and tubed, wherein the tubeless vacuum tire steel ring is of an integrated structure and is formed by rolling equal-thickness steel belts, the ear height of lotus leaf seat rings on two sides of the vacuum tire steel ring can not be too high for guaranteeing the sleeving of the vacuum tire, and the structure ensures that the tire needs special equipment or tools for installation, and is labor-consuming and time-consuming. Although a part of vacuum tire steel rims are convenient for mounting the tire, the whole structure is complex, the airtightness is poor, and the vacuum tire is easy to leak in the using process.

In addition, the existing rim steel ring can extrude the sealing ring to cause the deformation of the sealing ring after the vacuum tire is filled with high-pressure gas, so that the sealing effect of the sealing ring is poor, and the service life is short.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem that the vacuum tire steel ring structure is complicated among the prior art, the gas tightness is poor, the utility model provides a simple structure, the better vacuum tire steel ring of gas tightness.

In order to achieve the above purpose, the utility model provides a technical scheme is: the utility model provides a simple structure's vacuum tire steel ring, includes steel ring body, inflating valve, and steel ring body one end is big edge, and the steel ring body other end is the small edge, the inflating valve sets up between big edge and the small edge on the steel ring body, and the small edge cover of steel ring body is equipped with the retaining ring, and the inboard and the outside of retaining ring are equipped with first sealing washer and second sealing washer respectively, the big border position department of steel ring body is equipped with the third sealing washer, still is equipped with the layering that is used for compressing tightly the retaining ring.

Preferably, an inner annular groove and an outer annular groove are respectively formed in the inner side and the outer side of the retainer ring, and the first sealing ring and the second sealing ring are respectively embedded in the inner annular groove and the outer annular groove.

Preferably, a small edge ring groove matched with the inner ring groove of the retainer ring in position is arranged at the small edge position of the steel ring body, and the steel ring body is sealed with the retainer ring through a first sealing ring arranged between the inner ring groove and the small edge ring groove in a working state.

Preferably, a large-edge ring groove is formed in the large edge of the steel ring body, and the third sealing ring is mounted in the large-edge ring groove.

Preferably, in the working state, the bottom of the retainer ring is in contact with the steel ring body.

Preferably, the curvature of the outer side of the retaining ring is adapted to the curvature of the tyre.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the first sealing ring and the second sealing ring are respectively arranged on the inner side and the outer side of the retainer ring, so that the sealing performance between the steel ring body and the retainer ring and between the retainer ring and the tire is ensured, and the vacuum tire is prevented from leaking on one side of the small edge of the steel ring body; and set up the third sealing washer in the big marginal position department of steel ring body, can avoid the vacuum tire to take place the gas leakage on steel ring body big marginal one side, whole guarantee vacuum tire that can be fine is lasting stable work on the steel ring.
