Example Embodiment

[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...

Abstract

The invention discloses a non-welded automobile transmission shaft. The non-welded automobile transmission shaft mainly comprises a welding fork, a steel ring and a steel tube, wherein an inner splineis arranged on the inner surface of the steel ring; the welding fork and the steel tube are equipped with outer splines; and one end of the steel ring is fixedly connected to the welding fork, and the other end of the steel ring is fixedly connected to the steel tube. The non-welded automatic transmission shaft adopts a brand-new non-welded structure, adopts a pressing way to completely replace the original welding process, does not generate waste gas and soot for melting and welding, does not affect jump quality of a transmission shaft as a result of high welding heat, does not need to purchase professional equipment such as friction welding and laser welding, does not generate high energy consumption, and reduces production cost while improving product quality.

Description

technical field [0001] The invention relates to the field of automobile transmission shafts, in particular to a non-welding automobile transmission shaft. Background technique [0002] In the existing domestic miniature car transmission shaft structure, the welding fork and the shaft tube are mainly connected by welding. At present, the mainstream welding process is fusion welding, which will generate welding exhaust gas and smoke, and the high heat of welding will cause the deformation of the shaft tube and affect the runout quality of the transmission shaft. In addition, fusion welding, laser welding and other methods need to purchase corresponding equipment separately. The required equipment is expensive and energy-consuming, which is not conducive to the reduction of product production costs. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a non-welding automobile transmission shaft. ...
