[0011] The present invention will be described in detail below in conjunction with the drawings:
[0012] Example: As shown in the figure, this kind of non-welded automobile drive shaft mainly includes welding fork 1, steel ring 2, steel pipe 3. The inner surface of steel ring 2 has internal splines, and the welding fork 1 and steel pipe 3 have outer For the spline, one end of the steel ring 2 is fixedly connected to the welding fork 1 and the other end is fixedly connected to the steel pipe 3. Both the welding fork 1 and the steel pipe 3 are pressed into the steel ring 2 in a press-fitting manner, so that the welding fork 1 and the steel pipe 3 are fixedly connected.
[0013] The invention redesigns the structure of the drive shaft, adopts press fitting to completely replace the original welding method, does not produce fusible welding waste gas, smoke, and heat affected zones, and does not need to purchase friction welding, laser welding and other professional equipment, which ef...
