Wherein, the end of the shaft portion is provided with external splines, and the end of the tooth set part is provided with internal spline.
Further, the transition part is a frustum cone structure.
Further, the angle between the axis of the busbar of the frustum cone structure and the frustum cone structure is less than or equal to 30
Degree.
Further, tooth set part is internally provided with accommodating chamber, and the internal spline is located in the accommodating chamber.
Further, venthole is offered on the side wall of the accommodating chamber, the venthole is located at the internal spline and institute
It states between transition part.
Further, the material of the axle construction is carbon alloy structural steel.
Another aspect according to the present invention provides a kind of automobile, including：Automobile front axle inner shaft as described above.
The beneficial effects of the invention are as follows：
Above-mentioned technical proposal using integrally formed axle construction, avoids the shaft portion of bridge inner shaft before orthodox car
Part unstable problem of solder joint caused by being attached by the way of welding is covered, while reduce the design of spline pair with tooth,
Also the sliding bearing position decentraction at two before and after automobile front axle inner shaft is solved the problems, such as.

Specific embodiment
Exemplary embodiment of the present invention is more fully described below with reference to accompanying drawings.Although the present invention is shown in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the present invention without should be by embodiments set forth here
It is limited.It is to be able to be best understood from the present invention, and can be by the scope of the present invention on the contrary, providing these embodiments
Completely it is communicated to those skilled in the art.
As shown in Figure 1, an embodiment of the present invention provides a kind of automobile front axle inner shaft, which includes：
Integrally formed axle construction 1, middle shaft structure 1 include：
The shaft portion 11 of a diameter of first numerical value；
The tooth set part 12 of a diameter of second value, the first numerical value are less than second value；
Connect shaft portion 11 and the transition part 13 of tooth set part 12；
Wherein, the end of shaft portion 11 is provided with external splines, and the end of tooth set part 12 is provided with internal spline.
It should be noted that the axle construction 1 that shaft portion 11, tooth set part 12 and transition part 13 are formed is integrally formed,
It is not spliced between each section with welding or other modes, in order to ensure the intensity of axle construction 1 and stability, axle construction
1 material is carbon alloy structural steel, preferably, for medium carbon structural alloy steel, such as 40Cr, 40MnB, 42CrMo etc., but it is unlimited
In this.
In the embodiment of the present invention, using integrally formed axle construction 1, the axle portion of bridge inner shaft before orthodox car is avoided
11 are divided to cover the unstable problem of solder joint caused by being attached by the way of welding of part 12 with tooth, while reduce spline pair
Design also solves the problems, such as the sliding bearing position decentraction at two before and after automobile front axle inner shaft.
In order to reduce the stress concentration generated due to changes of section is larger between shaft portion 11 and tooth set part 12, improve
Part strength, on the basis of foregoing invention embodiment, in the embodiment of the present invention, transition part 13 is a frustum cone structure.
It should be noted that the transition part 13 of frustum cone structure is so that shaft portion 11 and the connection more adduction of tooth set part 12
Reason, can greatly reduce the structural stress generated due to the abrupt change of cross-section, preferably, the axis of the busbar of frustum cone structure and frustum cone structure
Between angle be less than or equal to 30 degree, such as the size of the angle can be unspecified angle between 15 ° to 20 °.
