Steering column.
The utility model provides a kind of steering column, including：Tubing string top with the first rigidity and with the second rigidity
Tubing string bottom, the tubing string top and the tubing string bottom are connected, and first rigidity is more than second rigidity.
Further, the tubing string top is aluminum tubing string top, and the tubing string bottom is sheet metal component tubing string bottom.
Further, the tubing string upper inside wall is provided with the first groove, and the connection end of the tubing string bottom is provided with projection, institute
Connection end is stated to insert in the tubing string top, and the first groove described in the projection clamping.
Further, the tubing string upper inside wall is additionally provided with the second groove, second groove described provided with holding out against
The snap ring of connection end.
Further, the snap ring that the snap ring includes connecting holds out against portion and snap ring end, and institute is inserted in the snap ring end
The second groove is stated, the snap ring portion of holding out against holds out against the connection end.
Further, the snap ring is snap ring.
Further, second groove is deeper than first groove.
Further, tolerance ring is cased with the connection end of the tubing string bottom, the tubing string top is inserted in the connection end
Interior, the tolerance ring and the inwall on the tubing string top are interference fitted.
Tubing string is made by mixing by using different-stiffness material in the utility model, so that while rigidity requirement is met,
Reduce holistic cost.

Embodiment
The utility model is described in more detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in figures 1-4, a kind of steering column of the utility model, including：Tubing string top 1 and tool with the first rigidity
There is the tubing string bottom 2 of the second rigidity, the tubing string top 1 and the tubing string bottom 2 are connected, and first rigidity is more than
Second rigidity.
Tubing string top 1 and tubing string bottom 2 are made using the material of different-stiffness, therefore, it is possible to use the big material of rigidity
Tubing string top 1 is made, so that rigidity requirement is met, meanwhile, tubing string bottom 2 is made by using the small material of rigidity, so as to drop
Low holistic cost.
Tubing string is made by mixing by using different-stiffness material in the utility model, so that while rigidity requirement is met,
Reduce holistic cost.
In one of the embodiments, the tubing string top 1 is aluminum tubing string top, and the tubing string bottom 2 is sheet metal component
Tubing string bottom.
In the present embodiment, aluminum tubing string top can meet rigidity requirement well, and sheet metal component tubing string bottom can then be reduced
Holistic cost.
In one of the embodiments, the inwall of tubing string top 1 is provided with the first groove 11, the company of the tubing string bottom 2
Connect end 21 and be provided with projection 22, the connection end 21 is inserted in the tubing string top 1, and the first groove described in the clamping of the projection 22
11。
As shown in figure 3, during assembling, the connection end 21 of tubing string bottom 2 is inserted in tubing string top 1, and is blocked by projection 22
Tight first groove 11 so that tubing string top 1 and tubing string bottom 2 are connected.
In one of the embodiments, the inwall of tubing string top 1 is additionally provided with the second groove 12, second groove 12
Provided with the snap ring 3 for holding out against the connection end 21.
The present embodiment increases snap ring 3, holds out against connection end 21 by snap ring 3 so that tubing string top 1 and tubing string bottom 2 coordinate
Closely.
In one of the embodiments, the snap ring that the snap ring 3 includes connecting holds out against portion 31 and snap ring end 32, the card
Second groove 12 is inserted in ring end 32, and the snap ring holds out against portion 31 and holds out against the connection end 21.
In assembling, first snap ring 3 is inserted in tubing string top 1 so that the second groove 12 is inserted in snap ring end 32, then inserts
Enter tubing string bottom 2, connection end 21 holds out against the groove 11 of portion 31 and first by snap ring and is matched for clamping tightly.
In one of the embodiments, the snap ring 3 is snap ring.
The present embodiment snap ring 3 is snap ring, is easy to be put into tubing string top 1 and the second groove of clamping 12.
In one of the embodiments, second groove 12 is deeper than first groove 11.
Specifically, the second groove 12 and the first groove 11 successively into a ladder, are easy to snap ring to insert and hold out against connection end.
As shown in Figure 5, Figure 6, in one of the embodiments, it is cased with tolerance ring on the connection end 21 of the tubing string bottom 2
