And the inner side surface of the tail part of the retainer ring and the bulge on the inner side of the retainer ring body are in circular arc transition.

The bent plate comprises a plate body and a side wall, and a conical surface is arranged between the plate body and the side wall.

Wherein, a plurality of screw holes are arranged on the plate body of the bent plate.

And the outer diameter of the side wall of the bent plate is matched with the inner diameter of the wheel rim.

And the end part of the side wall of the bent plate is welded and fixed with the rim.

Wherein, the rim is of an integrated structure.

The utility model discloses an above-mentioned technical scheme's beneficial effect as follows:

in the scheme, the wheel rim can be effectively supported by the bent plate of the two-piece wheel structure, the strength and the bearing capacity of the wheel are improved, the two-piece wheel structure cannot deform due to large stress, and therefore the two-piece wheel structure is suitable for bearing large industrial vehicles, the check ring is pressed tightly after the tire is inflated, the check ring cannot pop up, and the whole wheel structure is safe and reliable.

Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 2 to 3, an embodiment of the present invention provides a two-piece wheel structure, including a rim body 1 and a retainer ring 2 disposed at an outer side of one end of the rim body 1, wherein the rim body 1 includes a rim 11 and a bent web 12 disposed at an inner side of the rim 11, and a recess adapted to the retainer ring 2 is disposed at an outer side of an end portion of the rim 11; the retainer ring 2 comprises a retainer ring body 21 and a tail part 22 connected with the retainer ring body 21, the tail part 22 is arranged in a recess of the rim 11, a bulge is arranged on the inner side of the retainer ring body 21, and a groove matched with the bulge is arranged on the outer side of the rim 11.

In this embodiment, the recess of the rim 11 can ensure that the diameter of the outer sidewall of the retainer ring 2 is the same as the diameter of the outer sidewall of the other end of the rim body 1, so as to meet the requirement of a flat-bottom wheel structure. After the wheel is assembled with the tire, the bead seat of the tire is matched with the outer side surface of the retainer ring 2, and the retainer ring 2 is tightly pressed after the tire is inflated, so that the retainer ring 2 cannot be popped up, and the safety and reliability of the whole wheel structure are ensured.

The inner side surface of the tail part 22 of the retainer ring 2 and the bulge on the inner side of the retainer ring body 21 are in arc transition, so that the retainer ring 2 is conveniently assembled on the rim body 1.

The radials 12 includes plate body and lateral wall, the plate body with be equipped with the taper face between the lateral wall, in order to avoid rim 11's sunken, the taper face with be the circular arc transition between the plate body.

A plurality of screw holes are formed on the plate body of the radial bent plate 12.

The outer diameter of the side wall of the bent plate 12 is matched with the inner diameter of the cylinder body of the rim 11, and the end part of the side wall of the bent plate 12 is fixedly connected with the rim 11 through assembly welding so as to improve the strength of the wheel and improve the bearing capacity of the wheel.

The rim 11 is an integral rolling type rim and is of an integral structure, the thickness of a cylinder body of the integral rolling type rim is larger than that of an existing steel rim, and bearing capacity is enhanced.

According to the scheme, the wheel rim can be effectively supported by the bent plate of the two-piece wheel structure, the wheel strength and the bearing capacity are improved, the two-piece wheel structure cannot deform due to large stress, and therefore the two-piece wheel structure is suitable for bearing large industrial vehicles, the check ring is pressed tightly after the tire is inflated, the check ring cannot pop up, and therefore the whole wheel structure is safe and reliable.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
