The invention provides a hub inner ring, a manufacturing method of the hub inner ring, a hub assembly and a manufacturing method of the hub assembly. The hub inner ring is a hollow cylinder and is provided with a plurality of protruding structures. The protruding structure protrudes outwards from the outer circumferential face of the hollow cylinder of the hub inner ring and is obtained in the casting process. A plurality of concave structures are arranged on the joint face of the hub and the hub inner ring, and the concave structures are formed outside the corresponding convex structures in a shape matching mode through the imbedding technology. The hub is made of the light alloy material, and the hub inner ring is made of the iron-carbon alloy, so that the weight of the hub can be reduced while the structural strength requirement of the hub is met, and the bonding strength and the heat conductivity coefficient between the hub and the hub inner ring can be improved through the convex structures and the concave structures.

    本发明提出一种轮毂内圈及其制造方法、轮毂组件及其制造方法。其中的轮毂内圈呈空心圆柱体,并具有多个凸起结构。所述凸起结构从轮毂内圈的空心圆柱体的外周面向外凸出,并在铸造过程中取得。轮毂与轮毂内圈的接合面上具有多个凹陷结构,所述凹陷结构通过镶铸工艺而形状匹配地成形于对应的凸起结构的外部。本发明中的轮毂采用轻质合金材料制成,轮毂内圈采用铁碳合金制成,从而能够在满足轮毂结构强度要求的同时减少轮毂的重量,本发明还能通过凸起结构与凹陷结构来提高轮毂与轮毂内圈间的结合强度和导热系数。
