The wheel-side wheel bolt connecting structure provided by the utility model has the advantages that the traditional stud is replaced by the press-fitting bolt, the wheel bolt assembling efficiency is improved, the purchasing and processing cost is reduced under the condition of not changing the overall design, and meanwhile, the stop structures are formed by respectively arranging the corresponding stop parts on the wheel hub and the bolt to prevent the press-fitting bolt from rotating.
Drawings
FIG. 1 is a schematic illustration of a prior art stud connection;
FIG. 2 is a side schematic view of the present invention;
fig. 3 is a schematic end view of the present invention.
Reference numerals: the structure comprises a hub 1, a stud 2, a washer 3, a nut 4, a press-fitting bolt 5, a stop excircle 6, a straight notch 7 and a mounting gap 8.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 2 and 3, the bolt connection structure for the wheel rim wheel of the utility model comprises a wheel hub 1, wherein bolts are arranged on the circumference of the wheel hub 1, the bolts are press-fitting bolts 5, the press-fitting bolts 5 are in interference fit with the wheel hub 1, a first stop part is arranged at a position of the wheel hub 1 corresponding to the head of the press-fitting bolts 5, a second stop part is arranged at a position of the head of the press-fitting bolts 5 corresponding to the first stop part, and the first stop part and the second stop part are matched to form a stop structure for preventing the press-fitting bolts 5 from rotating.
As shown in figure 2, in the wheel-side wheel bolt connecting structure, the press-fitting bolts 5 and the holes of the wheel hub 1 are designed to be in interference fit, so that the bolts are prevented from falling off, the bolts can be directly press-fitted, and the installation labor cost can be effectively reduced. However, the press-fitting bolt 5 is different from the stud 2 in that the head part of the press-fitting bolt is not provided with a nut, and the problem of rotation may occur during connection, so that the first stop part is arranged on the hub 1, the second stop part is arranged on the head part of the press-fitting bolt 5, and the first stop part and the second stop part are matched with each other to form a stop structure, so that the press-fitting bolt 5 is prevented from rotating.
The first stopping part can be a convex block structure, a groove structure and the like positioned on the side face of each press-fitting bolt 5, the second stopping part can be a hexagonal head, a clamping groove structure and the like, in the preferred embodiment of the application, a stopping excircle 6 is arranged on the hub 1 along the circumferential direction, the stopping excircle 6 is positioned on the inner side of the head of the press-fitting bolt 5, and the outer peripheral surface of the stopping excircle 6 forms the first stopping part. The stop outer circle 6 is more convenient to machine compared with other stop structures, wherein the best mode is that the stop outer circle 6 and the hub 1 are of an integral structure and can be directly cast along with the hub 1.
In another embodiment of the present application, in order to match the stop outer circle 6, one side of the press-fit bolt 5 facing the stop outer circle 6 is provided with a straight notch 7, the straight notch 7 forms the second stop portion, and the straight notch 7 and the outer peripheral surface of the stop outer circle 6 cooperate to form a stop structure. The straight notch 7 is simple to process, and only one side of the bolt is cut off on the basis of the ordinary press-fitting bolt 5.
Although the effect of the first stop part being close to the second stop part or even directly contacting it is best, this increases the difficulty of press fitting, so that in the preferred embodiment of the present application the first stop part and the second stop part have a mounting gap 8. The existence of the mounting gap 8 can prevent the first stopping part from interfering with the bolt during press fitting, and the mounting gap 8 is usually 0.5 +/-0.1 mm.
