For the axis direction of steering drive axle, "inner", "outside" refer to the inner and outer of corresponding component profile, in addition, in the disclosure
Term " first " " second " used etc. is that do not have succession and importance to distinguish an element and another element.
In addition, in the following description when referring to the accompanying drawings, unless otherwise indicated, the same numbers in different attached drawings indicate the same or similar and want
Element.
As depicted in figs. 1 and 2, the disclosure provides a kind of steering drive axle, which includes inner shaft 1 and be set in
The first axle sleeve 2 that can be movable relatively outside inner shaft 1 along axial direction, wherein inner shaft 1 includes first for being connected with universal joint 3
Shaft part 11, the second shaft part 12 connecting with 2 spline of the first axle sleeve, and the extension shaft part 13 being connected with the second shaft part 12, prolong
Long shaft part 13 is formed as the divergent segment 131 that the diameter of axle gradually increases, and the end of divergent segment 131 can be connected to the second shaft part 12 and
On the end face that one axle sleeve 2 is connected.
Through the above technical solutions, inner shaft 1 and the first axle sleeve 2 can be movable relatively along axial direction, the steering drive axle is realized
It is scalable, it can satisfy the design requirement of different height, different flip angle driver's cabins, extend shaft part 13 and be formed as the diameter of axle gradually
On the one hand increased divergent segment 131 can increase the telescopic range of the steering drive axle, meet the design need of general vehicle
It asks, on the other hand, the end of divergent segment 131 can prevent inner shaft 1 from deviating from from the first axle sleeve 2, more securely and reliably.
Extending shaft part 13 not only has anti-off effect, while can also increase the telescopic range of steering drive axle, at this
In open, as shown in figure 3, extending shaft part 13 including above-mentioned divergent segment 131 and between the second shaft part 12 and divergent segment 131
Glissile segment 132, the path of the diameter of axle of glissile segment 132 less than the second shaft part 12.Specifically, as shown in Figure 3, D is inner shaft 1 and the
One axle sleeve, 2 spline housing spends key length, and the maximum length of steering drive axle subtracts for the sum of the length of inner shaft 1 and the first axle sleeve 2
D, the diameter of axle of glissile segment 132 less than the second shaft part 12 path, in this way, inner shaft 1 can be relative to first under state shown in the figure
Axle sleeve 2 continues the length of glissile segment 132 axially movable, increases the telescopic range of steering drive axle, can be to a certain extent
The scalable length shortened caused by making up because of spline housing spline.
Further, in the disclosure, as shown in figure 3, being arranged with anti-decylization 4 on glissile segment 132, the outer diameter of anti-decylization 4
It is equal with the major diameter of the second shaft part 12.Anti-decylization 4 is set on glissile segment 132, will not influence the steering drive axle in glissile segment
It is flexible at 132, when the end of divergent segment 131 supports anti-decylization 4 on the end face of the second shaft part 12, inner shaft can be prevented
1, by deviating from the first axle sleeve 2, plays anti-off effect, improves the safety of the steering drive axle.
The maximum diameter of axle of divergent segment 131 is greater than the diameter of axle of the second shaft part 12 and less than the internal diameter of the first axle sleeve 2.Here,
The diameter of axle of two shaft parts 12 refers to the major diameter of the second shaft part 12, in this way, both will not influence inner shaft 1, especially at extension 13, phase
Axial movement for the first axle sleeve 2, while can guarantee that the end of divergent segment 131 is supported in the second shaft part 12 and the first axle sleeve
On the end face of 2 splines connection, anti-off effect is played.
In the disclosure, extending shaft part 13 further includes the limit section 133 being connected with divergent segment 131, limits the axis of section 133
Diameter is greater than the diameter of axle of the second shaft part 12 and less than the internal diameter of the first axle sleeve 2.In this way, can be at glissile segment 132 and divergent segment 131
It realizes relative motion of the inner shaft 1 relative to the first axle sleeve 2, is connected to the second shaft part 12 and the when inner shaft 1 moves to limit section 133
On the end face of one axle sleeve, 2 spline connection, anti-off effect can be played, while limiting section 133 to move back and forth in the first axle sleeve 2,
Clamping stagnation and pause will not occur.
In the present embodiment, the second shaft part 12 and the ratio of extension 13 length of shaft part can be 6:1-10:1.It can basis
The height of driver's cabin needs the angle overturn to be designed the size of the second shaft part 12 and extension shaft part 13, general to meet
The design requirement of vehicle, at the same the steering drive axle most in short-term, gap between inner shaft 1 and the first axle sleeve 2 and will be under
The gap between the first axle sleeve 2 and the second axle sleeve 5 introduced in text should be small as far as possible, to meet the requirement of steering sensitivity.
In addition, in the disclosure, as shown in Figure 1, the steering drive axle further includes be set in outside the first axle sleeve 2
Two axle sleeves 5, the first axle sleeve 2 and the second axle sleeve 5 can be movable relatively along axial direction.In this way, inner shaft 1 can be relative to the first axle sleeve 2 along axis
To stretching, the first axle sleeve 2 can be axially retractable relative to the second axle sleeve 5, further increases the steering drive axle in the axial direction
Telescopic range can satisfy the design requirement of general vehicle.In other embodiments, can according to the height of driver's cabin and
The difference of flip angle, it is appropriate to increase the quantity for being arranged axle sleeve or relevant design is carried out to the length of multiple axle sleeves, to increase
The stroke of the steering drive axle.
Further, in the disclosure, the first axle sleeve 2 can be splined with the second axle sleeve 5 or be connected by retainer.
Similarly, to prevent the first axle sleeve 2 from deviating from from the second axle sleeve 5, the rate of travel of the two is limited, can be set in spline
Rolling element and the retaining ring for being limited to rolling element are set, in addition, the first axle sleeve 2 and the second axle sleeve 5 pass through retainer
It is more general that the embodiment of connection and specific structure for preventing the first axle sleeve 2 from deviating from from the second axle sleeve 5 belong to application
Time technology, be not described in detail herein.
According to the second aspect of the disclosure, a kind of vehicle is also provided, which includes steering transmission presented hereinabove
Axis.The vehicle has all beneficial effects of above-mentioned steering drive axle, does not do and excessively repeats herein.
The preferred embodiment of the disclosure is described in detail in conjunction with attached drawing above, still, the disclosure is not limited to above-mentioned reality
The detail in mode is applied, in the range of the technology design of the disclosure, a variety of letters can be carried out to the technical solution of the disclosure
Monotropic type, these simple variants belong to the protection scope of the disclosure.
It is further to note that specific technical features described in the above specific embodiments, in not lance
In the case where shield, can be combined in any appropriate way, in order to avoid unnecessary repetition, the disclosure to it is various can
No further explanation will be given for the combination of energy.
In addition, any combination can also be carried out between a variety of different embodiments of the disclosure, as long as it is without prejudice to originally
Disclosed thought equally should be considered as disclosure disclosure of that.
