Finally, the press is started to realize the press-fitting of the wheel core and the wheel. Among them, the outer wall of the first positioning column contacts the inner wall of the wheel core to realize the positioning of the wheel core to avoid radial movement of the wheel core; the second positioning column is set to limit the rotation of the wheel core. Among them, the third positioning column is set to avoid the wheel from rotating relative to the wheel core. The present invention realizes the positioning and alignment of the wheel core and the wheel through the first positioning column, the second positioning column and the third positioning column, so that the wheel hub matching groove and the wheel core matching groove are aligned during press-fitting to ensure the press-fitting effect.

[0008] Due to process problems, there is an assembly error between the support seat and the base plate. The base plate can be rotated to rotate with the support plate. After the third positioning column on the support plate is aligned with the second positioning column, the fixing bolts can be fixed to ensure the press-fitting accuracy.

[0009] Preferably, the support plate is provided with a positioning groove which is upwardly open and communicated with the through groove, a ring-shaped positioning ring is fixed in the positioning groove, and the third positioning column is fixed to the positioning ring. The positioning ring is provided to facilitate the fixation of the third positioning column to the support plate, so as to facilitate the assembly of the present invention. The positioning ring and the support plate can be made of different materials, and the wheel hub is supported by the more wear-resistant positioning ring.

[0010] Preferably, the positioning ring has a second fixing hole that penetrates radially, one end of the third positioning column passes through the second fixing hole and is fixed to the support plate, and the other end of the third positioning column is located in the through groove. The third positioning column is not only used to locate the wheel hub, but also used to fix the positioning ring to the support plate. The third positioning column can be a self-tapping screw.

[0011] Preferably, the elastic member is a rectangular spring. The elastic member adopts a rectangular spring, which has a larger expansion amount and is more suitable for press-fitting with a longer stroke.
