Preferably, the hexagonal structure of described nut body is the outer-hexagonal header structure, and its diameter is greater than the diameter 3 ~ 5mm of the hollow round table part of nut body.
Described back-up ring is the cap-shaped structure of indent, the end of the hexagonal structure part of its welded nut body.
Described back-up ring material is alloy material, is preferably PA66.
Described nut body material is alloy material, is preferably No. 35 steel or SCM435.
During nut screwing clamping, the conical surface of hollow round table and the wheel set mounting hole conical surface compress to realize the fixing of wheel, and the simultaneous buffering pad is close to until compress and effectively fix with wheel cover under the pressuring action of back-up ring.
Useful technique effect of the present utility model is as follows:
The wheelhouse portions set screw nut that the utility model provides has realized that wheel and wheelhouse portions are connected with the effective of hub bearing, can reduce wheelhouse portions weight, reduces simultaneously the Steel Rim producting process difficulty.It is reasonable in design, and is simple in structure, reliable operation.

Embodiment
Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.In the situation that does not deviate from the utility model spirit and essence, modification or replacement to the utility model structure, parameter or condition are done all belong to protection domain of the present utility model.
If do not specialize, the conventional means that used technological means is well known to those skilled in the art among the embodiment.
Referring to Fig. 1,
The utility model provides a kind of wheelhouse portions set screw nut, comprises nut body 1 and the buffering catch 2 of internal thread; Described nut body outer circumferential side has annular groove 4, the nut body of annular groove 4 one sides is hollow round table structure 1-1,1-2, the nut body of annular groove 4 opposite sides is hexagonal structure 1-3, and the end of described nut hexagonal structure 1-3 part originally is provided with back-up ring 3; Described buffering catch 2 is sleeved in the annular groove 4 for the loop configuration with opening.
Described annular groove 4 is positioned at nut body 1 outer circumferential side apart from the position of end 1/2.
Described annular groove 4 diameters are 21mm, and recess width is 3.2mm.
The outer diameter 2-1 of described buffering catch 2 is 28mm, and the inner diameter 2-2 of described buffering catch 2 is 21mm, and the thickness of described ring buffering catch 2 is 3mm.
The A/F of described buffering catch 2 is 3mm.
The hollow round table of described nut body 1 partly comprises one section hollow circuit cylinder 1-2 and one section bottomless round platform 1-1 of hollow, and the outer diameter of described hollow circuit cylinder 1-2 is greater than the outer diameter of groove 4.
