Detailed Description
It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
The present invention is described in further detail below with reference to specific examples, which should not be construed as limiting the scope of the invention as claimed.
Example 1
As shown in fig. 1 to 5, the present embodiment discloses a split forged hub for heavy-duty vehicles, which includes a body 1 integrally forged and formed and an outer ring 2 of a split design connected to the body 1.
Specifically, the body 1 includes an inner ring 5, a first flange 6 and a second flange 7, the first flange 6 and the second flange 7 are respectively located on both axial sides of the inner ring 5, and the first flange 6 and the second flange 7 each protrude radially outward from the inner ring 5.
The outer ring 2 is connected by material connection to a first flange 6 and a second flange 7 on the body 1. The "material connection" may be a welding, and the second weld 4 is formed between the outer ring 2 and the first flange 6/the second flange 7, respectively. The outer ring 2 is located radially outwardly of the inner ring 5 in a radially spaced manner such that the outer ring 2 and the inner ring 5 form a double-layer structure and such that an annular cavity 8 is provided between the inner ring 5 and the outer ring 2.
The outer ring 2 includes a first outer ring portion 21 and a second outer ring portion 22 in a curved plate shape, the first outer ring portion 21 and the second outer ring portion 22 are located at different positions in the circumferential direction of the hub and are spliced into a ring shape (in other possible cases, the outer ring 2 may be spliced into an incomplete ring shape, and only covers a part of the circumferential direction of the hub), the first outer ring portion 21 and the second outer ring portion 22 are connected to each other by welding, and a first welding seam 3 is formed between the first outer ring portion 21 and the second outer ring portion 22.
