[0028] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

In the description of the present invention, unless otherwise specified, "multiple" means two or more.
[0030] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0031] See also Figure 1-Figure 4 As shown, Figure 1 It is a schematic diagram of the structure of a wheel rim in the prior art. Figure 2 It is a structural schematic diagram of the retaining ring groove in the prior art. Figure 3 is a schematic diagram of the structure of the spoke in the prior art, Figure 4 It is a schematic diagram of the structure of the steel ring in the prior art. Figure 4 As shown, in the prior art, when the rim, the retaining ring groove and the spoke are connected, the end face of the rim is welded to the end face of the retaining ring groove at A and B, and the end face of the spoke is welded to the other end face of the retaining ring groove at ER. The steel rim in the prior art has many welding points, and the material becomes brittle due to heat when the spoke and the retaining ring groove are welded at A and B. The reason is that the Z point of the retaining ring groove is the strongest point under stress. Although it is thickened here, the welding point becomes brittle due to heat. When the stress is severe during use, the Z point will break, causing safety hazards.
[0032] In view of the above problems, the embodiment of the utility model provides a new steel ring structure to prevent the retaining ring groove and the rim from being broken due to heat and stress when being welded, thereby improving the structural strength.
[0033] Combine the following Figure 5-Figure 7 The technical solution provided by the utility model is described in more detail.
[0034] Embodiment 1:
[0035] The utility model provides a novel steel ring structure, comprising a rim 1, a retaining ring groove 2 and a spoke 3, wherein: the spoke 3 is welded to one end of the retaining ring groove 2, or the spoke 3 and the retaining ring groove 2 are an integral spin-formed structure; the other end of the retaining ring groove 2 is formed with a plug-in portion, the plug-in portion is squeezed and inserted into the rim 1, and is welded and fixed to the rim 1, thereby fixing the rim 1 and the retaining ring groove 2 in connection.
[0036] The new steel ring structure of this embodiment has a plug-in portion that is squeezed and inserted into the rim 1, which facilitates the positioning of the rim 1 and the retaining ring groove 2 before welding, thereby improving the concentricity of the rim 1 and the retaining ring groove 2. The plug-in portion 20 is welded and fixed to the rim 1, which can change the position of the welding point and prevent the retaining ring groove 2 from breaking due to heat and stress when welding to the rim 1. It can fix the rim 1 and the retaining ring groove 2 and improve the structural strength.
[0037] See also Figure 5 As shown, as an optional embodiment, when the plug-in portion is squeezed and inserted into the rim 1, the rim 1, the retaining ring groove 2 and the spoke 3 are coaxially arranged.
[0038] This structure improves the concentricity of the rim 1, the retaining ring groove 2 and the spoke 3, and facilitates the assembly of the rim 1, the retaining ring groove 2 and the spoke 3.
[0039] As an alternative embodiment, see Figure 5 As shown, the retaining ring groove 2 includes an outer ring 22 and an inner ring 21, wherein: the outer ring 22 and the inner ring 21 are an integrally formed structure, the outer ring 22 extends radially along the retaining ring groove 2, and is welded or integrally spun with the spoke 3; the diameter of the inner ring 21 is smaller than the outer ring 22, and the inner ring 21 extends axially along the retaining ring groove 2, thereby forming a plug-in portion 20.
[0040] For the “plug-in portion 20”, see Figure 4 As shown, the "inner ring 21" of this embodiment forms the above-mentioned "insertion portion 20", see Figure 4 As shown, the inner ring 21 is inserted into the rim 1 as a plug-in part 20 .
[0041] contrast Figure 4 and Figure 5 As shown, in the prior art, the ends of the spoke and the retaining ring groove 2 are welded to the ends of the rim 1, and the welding points of the two are Figure 4 The solder joint ER is changed to Figure 5 The welding points C and D are used to weld the retaining ring groove 2 and the rim 1, so that the force applied during welding of the retaining ring groove 2 can be reduced, thereby preventing the retaining ring groove 2 from breaking.
[0042] The rim 1 of this embodiment is made by a spinning process, and the side walls of the rim 1 are of uneven thickness. The thickness is thicker at the location where the force is greater, and the thickness is thinner at the location where the force is less. That is, the rim 1 of this embodiment can use a plate of equal thickness, or spin thinner at the location where the force is not applied. Such an arrangement reduces weight and reduces material waste.
[0043] See also Figure 5 and Figure 6 As shown, two specific forms of spokes and retaining ring grooves 2 are provided in this embodiment.
[0044] See also Figure 6 As shown, one end of the retaining ring groove 2 for connecting with the rim 1 is formed with an outer contour groove 23 , and the plug-in portion 20 is constructed as a side wall of the outer contour. When the plug-in portion is squeezed and inserted into the rim 1 , the side wall of the rim 1 is at least partially located in the outer contour groove 23 .
[0045] The outer contour groove 23 facilitates the docking of the side wall of the rim 1 with the retaining ring groove 2, thereby facilitating the welding and fixing of the rim 1 and the retaining ring groove 2.
[0046] See also Figure 5 As shown, the outer contour groove 23 can be formed naturally when the outer ring 22 and the inner ring 21 are formed, or, see Figure 6 As shown, the outer contour groove 23 is an angled retaining ring groove milled out from the outer wall of the retaining ring groove 2.
[0047] As an alternative embodiment, see Figure 5 and Figure 6 As shown, when the spoke 3 is welded and fixed to the retaining ring groove 2, the retaining ring groove 2 has a horizontal section, and the horizontal section is spliced and welded to the end of the spoke 3.
[0048] The above structure facilitates welding after the spoke 3 and the retaining ring groove 2 are butted against each other, thereby improving the connection strength of the structure.
[0049] Embodiment 2:
[0050] The difference between this embodiment and embodiment 1 is that, see Figure 7 As shown, one end of the spoke 3 connected to the retaining ring groove 2 is not larger than the inner diameter of the retaining ring groove 2, and the end of the spoke 3 extends into the retaining ring groove 2 and is welded and fixed to the retaining ring groove 2.
[0051] The above structure facilitates the concentric arrangement of the spoke 3 and the retaining ring groove 2 and can ensure the structural strength.
