The structure of the metal fastener 51 in the second embodiment is completely the same as that of the metal fastener 23 in the first embodiment.
The rim 60 is of an inwardly recessed annular structure, and a valve mounting hole 63 for mounting a valve is provided in the rim 60, and the axis of the valve mounting hole 63 is parallel to the axis of the disk portion 40.
Specifically, the rim 60 has two outwardly extending flanges 62, the two flanges 62 forming an annular groove 61.
Any one of the flanges 62 is provided with a valve mounting hole 63 penetrating the flange, and the axis of the valve mounting hole 63 is parallel to the axis of the disk portion 40.
In the present embodiment, the valve mounting hole 63 penetrates from a side of the spoke 50 away from the hub cap to communicate with the annular groove 61 in the axial direction of the disc portion 40, that is, penetrates through a side flange 62 of the rim 60 away from the hub cap.
The metal mounting ring 42 and the metal ring 44 are fitted into the cavity 43 by an integral molding process. The metal fasteners 433 are fitted to the spokes 50 through an integral molding process.
Effects and effects of example two
In the second embodiment, an inflating valve mounting hole is arranged on one side, away from the mounting cavity, of the disc part, and the axis of the inflating valve mounting hole is parallel to the axis of the disc part. Because among the prior art, the wheel hub main part is made by metal, and the annular structure at chamber portion edge place is hollow out construction, inflates the valve cock mounting hole on this annular structure, if punch along parallel and disc axial direction, breaks the chamber portion easily, so the mode processing valve cock mounting hole that adopts the inclined hole among the prior art more, but the inclined hole of beating needs to involve the core pulling in the mould link again, problems such as drawing die inclination have increased the degree of difficulty of mould design. In the second embodiment, because the cavity part is of a solid structure, the cavity part can be drilled into a straight hole, namely, the axis of the valve mounting hole is parallel to the axis of the disk part, so that the difficulty of mold development is reduced, and the production efficiency is improved.
The above-described embodiments are merely illustrative of specific embodiments of the present invention, and the present invention is not limited to the description of the above-described embodiments.
In this embodiment, the cross section of the axis line of the disc portion 10 is approximately hexagonal, and in other embodiments, the cross section of the limiting portion may also be a quadrangle, a pentagon or a trimming shape, and the like, so long as the limiting portion is not circular, the effective torque providing can be realized, and the metal fastener is prevented from rotating.
