[0019]Example

[0020]Seefigure 1 withfigure 2 The present invention provides a technical solution: a lightweight high intensity, including the first axis of the bodium 1, the bottom of the first axis body 1 has a hollow port 4, and a fastening mechanism; Including the fixing rod 2, the first fixing ring 3, the second fixing wheel 5, and the cylinder 6, the end of the fixing rod 2 fixes a first fixing ring 3, and the extended axis of the cylinder 6 is fixed to the first axis body 1. The solid second fixing wheel 5, the vertical first axis body 1 is close to the first fixing ring 3, the cylinder 6 work, the extended axis of the cylinder 6, and the second fixing wheel 5 is closely passed to the vertical first axis body 1 The vertical first axis body 1 is fixed to facilitate a better forging of the vertical first axis body 1.

[0021]In the present embodiment, it is preferable that the inner wall of the first fixing ring 3 is fixed to a first rubber pad 7, the first rubber pad 7 is a ring; t...

Abstract

The invention discloses a light-weight high-strength shaft fork. The light-weight high-strength shaft fork comprises a first shaft fork body, wherein a hollow opening is formed in the bottom of the first shaft fork body, and the light-weight high-strength shaft fork further comprises a fastening mechanism. The light-weight high-strength shaft fork has the beneficial effects that the shaft fork isforged through the hydraulic forging technology, so that the blank forging steel utilization rate of parts is further increased, and raw materials and energy are greatly saved; an existing transmission shaft spline shaft yoke blank is hollowed through the combined die technology, so that the discharging weight of the transmission shaft spline shaft yoke is further reduced, waste of the raw materials is greatly reduced, energy can be saved, the total weight of a final product transmission shaft is further reduced, and the light weight requirement of an existing finished automobile factory is met; through the designed fastening mechanism, the vertical first shaft fork body is fixed stably, and the vertical first shaft fork body can be favorably forged better; and a first rubber pad and a second rubber pad are arranged, so that the first shaft fork body can be further fastened through the first rubber pad and the second rubber pad.

Description

Technical field[0001]The present invention belongs to the field of energy saving technologies, and more particularly to a lightweight junction fork.Background technique[0002]The shaft fork is a part of the drive shaft and is widely used in the car. Badk and pin joints achieve power transmission.[0003]Due to the relatively long axis, considering the structural structure of the forging hammer and mold, the current domestic bushing forging is basically flat forging, which is forging when the outer axis and ear hole axis are at the same time. Afterging, cutting treatment; flat forging due to structural problems, can not be directly forged in the bottom of the spline, resulting in increased weight, and due to the round-performed wire length, the material waste, the efficiency is reduced, and the tie is easy to cause The parts are displaced on the upper and lower parts of the part, affecting the quality of subsequent processing.[0004]In order to greatly save raw materials and energy; redu...
