Key；
The first end of casing, described sleeve pipe is provided with the second universal-joint fork, and the second end of described sleeve pipe is provided with fitting groove,
The internal diameter of the fitting groove and the outer diameter of the axis body are adapted, and the inner wall of the fitting groove is provided with to be coordinated with the external splines
Internal spline, to realize the scalable connection of described sleeve pipe and the axis body.
Steering column countershaft assembly as described above, wherein preferably, the tooth of the internal spline and the external splines
Number is 24.
Steering column countershaft assembly as described above, wherein preferably, the fitting groove axially penetrates through the set
Pipe.
Steering column countershaft assembly as described above, wherein preferably, be provided on the outer circumference surface of the axis body
Limit salient point for limiting the axis body stroke.
Steering column countershaft assembly as described above, wherein preferably, the limit salient point is equipped with two, radial direction
It is symmetrically disposed on the both sides of the axis body.
Compared with prior art, the utility model is occurred just by setting countershaft assembly to spline fitted in automobile
When face is collided, opposite sliding crumple occurs for the internal spline stress on external splines and casing on axis body, reduces automobile front and touches
Injury of the steering to occupant during hitting.

Specific implementation mode
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and cannot be construed to the utility model
Limitation.
As shown in Figures 1 to 4, the embodiments of the present invention provide a kind of steering column countershaft assembly, including：
Axis body 1, first end are provided with the first universal-joint fork 2, are equipped on the outer circumference surface of the second end of the axis body 1 outer
Spline 3.
The first end of casing 4, described sleeve pipe 4 is provided with the second universal-joint fork 5, and the second end of described sleeve pipe 4 is provided with dress
The outer diameter of slot allocation 6, the internal diameter of the fitting groove 6 and the axis body 1 is adapted, the inner wall of the fitting groove 6 be provided with it is described
The internal spline 7 that external splines 3 coordinates, to realize the scalable connection of described sleeve pipe 4 and the axis body 1.
Countershaft assembly is arranged between steering gear and steering column, and the axis body 1 passes through the first universal-joint fork 2 and steering
Tubing string is rotatably connected, and described sleeve pipe 4 is rotatably connected by the second universal-joint fork 5 with steering gear, and casing 4 and axis body 1 pass through
Scalable connection is realized in the engagement of internal spline 7 and external splines 3, when head-on crash occurs for automobile, external splines 3 on axis body 1 with
Opposite sliding crumple occurs for 7 stress of internal spline on casing 4, and steering is to occupant's during reducing frontal crash of vehicles
Injury.
Further, it is the integral strength of raising steering column jackshaft, the tooth of the internal spline 7 and the external splines 3
Number is 24 teeth, to improve the contact area and bonding strength of axis body 1 and casing 4, the internal spline 7 and the external splines 3
It is equivalent to slideway, ensure that the concentricity between axis body 1 and casing 4.
To improve the flexible stroke of steering column jackshaft, the limitation of interior installation space is broken through, the fitting groove 6 is axial
