Through above-mentioned technical scheme, the lightening hole of circumference evenly distributed on the spoke can reduce the required aluminum product of spoke production, reduces this wheel hub's manufacturing cost.

Preferably, the spoke is provided with a reinforcing plate, the reinforcing plate is located at an orifice of the lightening hole, the reinforcing plate is close to one side of the connecting piece, and the reinforcing plate and the spoke are integrally formed.

Through above-mentioned technical scheme, reinforce the board and can promote the structural strength that the spoke is close to connecting block one side for the spoke is close to connecting block one side and is difficult for taking place to warp, makes being connected between spoke and the connection piece become more stable.

Preferably, be provided with a plurality of spliced poles on the axletree installation department, a plurality of the spliced pole with the axletree installation department is central circumference evenly distributed, set up threaded hole on the spliced pole.

Through the technical scheme, the connecting column is arranged on the side wall of the axle mounting part, and the threaded hole is formed in the connecting column, so that the hub can be mounted more conveniently.

Preferably, the connecting post is integrally formed with the spoke proximate the end of the spoke.

Through above-mentioned technical scheme, can promote the structural strength of spoke with spoke integrated into one piece's spliced pole for spoke non-deformable.

Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

An iron-aluminum composite hub, as shown in fig. 1 and 2, includes an iron rim 1, an aluminum wheel disc 2 disposed inside the rim 1, an aluminum axle mounting portion 3 disposed inside the wheel disc 2, and an iron connecting piece 4 disposed near the rim 1 on the wheel disc 2.

The inner ring of the rim 1 is convexly provided with a circular convex ring 5, and the convex ring 5 and the rim 1 are coaxially arranged.

The spoke 2 is provided with a plurality of limiting protrusions 6 for the convex ring 5 to extend into near the rim 1, and the limiting protrusions 6 are circumferentially and uniformly distributed by taking the axle mounting part 3 as a center.
