Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
As shown in Figures 1 to 4, according to an embodiment of the invention, a kind of planet carrier assembly of automotive transmission, comprising: row
Carrier ontology 1 and planet carrier bracket 2, planet carrier body 1 integrally formed be sequentially arranged output shaft 11, clinch 12 and more
A interconnecting piece 13, output shaft 11 is integrally formed with being sequentially arranged and radial dimension is sequentially reduced the first output shaft part 111, the
Two output shaft parts 112 and third export shaft part 113, and the first output shaft part 111 is connect with clinch 12, the radial ruler of clinch 12
The very little radial dimension greater than output shaft 11, the center position of clinch 12 are equipped with first positioning hole 121, clinch 12 it is outer
Week is equipped with multiple first mounting holes 122 in axial direction extending, it is to be understood that the periphery of clinch 12 is referred to the
Towards external expansion and the region between first positioning hole 121 and the outermost end margin of clinch 12 centered on a positioning hole 121,
Multiple first mounting holes 122 are successively spaced from each other along the circumferential direction of first positioning hole 121 and are uniformly distributed, multiple interconnecting pieces 13
