Problems solved by technology
[0004] Since there are no peaks between the outer bead seat and the spoke surface and between the inner bead seat and the tread groove side, the gap between the tire and the rim and bead seat will There is a tendency to disengage, which poses a safety hazard
[0005] Again, because the air valve holes are in the inner side of the spokes, longer air valves are required to pass through the air holes and stretch out on the outer sides of the spokes, so that the tires can be inflated easily, and the operation is convenient; Significantly increased wheel imbalance

Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0018] Double humped steel commercial wheels such as image 3 and Figure 4 Shown:
[0019] It consists of a rim 12 with a valve hole 20, a spoke 17 with a middle hole 18 and a screw hole 16;
[0020] The air hole 14 provided on the side wall 15 of the spoke 17 and the air valve hole 20 arranged on the convex peak slope 19 of the rim 12 communicate with each other, and the air valve 13 installed on the air valve hole 20 is located in the air hole 14 The center of the spoke 17 does not pass through the side wall 15 of the spoke 17, and the outer surface of the edge 8 of the spoke 17 is connected with the inner surface of the spoke surface 7 of the rim 12, and the spoke 17 and the rim 12 are integrated, and then welded. firm.
[0021] On the left side of the center plane of the rim 12, between the outer bead seat 10 and the spoke surface 7, an arc-sha...

A commercial steel wheel with double bumps comprises spokes and a rim, wherein the rim is provided with the two bumps and bump inclined planes; an arc outer side bump and a tapered annular bump inclined plane are arranged on the left side of a center plane of the rim; an arc inner side bump is arranged on the right side of the center surface of the rim; an inflating valve hole for mounting an inflating valve is formed in the added bump inclined plane; a long valve which penetrates through an air hole and then inflates a tire is not required; and space formed by the inner side walls of the spokes and a non-tire-mounting surface of the rim is enlarged by moving the inflating valve hole to the bump inclined plane from a non-tire-surface groove side, and then the commercial steel wheel can be provided with a disc brake. By the technical scheme, the commercial steel wheel is simple in structure and convenient to manufacture, effects are obvious, potential safety hazards of an automobile are reduced, and the commercial steel wheel has high practical value.
Description
Technical field: [0001] The present invention relates to automotive components, especially steel commercial wheels. Background technique: [0002] A traditional steel commercial wheel is composed of a rim and a spoke. The outer side of the spoke edge is connected to the inner side of the spoke surface of the rim, and the spoke and the rim are formed into a whole by welding. There are screw holes and middle holes on the mounting surface of the spoke, and there are air holes on the side wall of the spoke. The air valve on the mouth hole passes through the air hole and stretches on the outside of the spoke. [0003] Among them, the rim is divided into inner rim, inner bead seat, tread groove side, bottom groove, non-tread groove side, spoke surface, outer bead seat, and outer rim. [0004] Since there are no peaks between the outer bead seat and the spoke surface and between the inner bead seat and the tread groove side, the gap between the tire and the rim and bead seat will...
