In the present embodiment, as shown in Fig. 2 steering column, including first tubing string 1 and second tubing string 2, first tubing string 1 and
Two tubing strings 2 are connected through a screw thread, and first tubing string 1 is made up of the first material, and second tubing string 2 is made up of the second material.
Due to steering column is divided into first tubing string 1 and second tubing string 2 in the present embodiment, and it is connected through a screw thread, the
One tubing string 1 is different from the material of second tubing string 2.So, the system of the material of high rigidity can be used the part for needing high rigidity
Into other parts are made using the material of low cost, reduce the cost of material.
Further, as shown in Fig. 2 first tubing string 1 is provided with internal thread 11, second tubing string 2 is provided with external screw thread 21,
The external screw thread 21 of second tubing string 2 is connected with the internal thread 11 of first tubing string 1.
During installation, the external screw thread 21 of second tubing string 2 is aligned with the internal thread 11 of first tubing string 1, then external screw thread 21 revolves
Enter in internal thread 11.
It is preferred that being provided with step surface (not shown) between the body and external screw thread 21 of second tubing string 2, the external diameter of body is more than
The diameter of external screw thread 21, transition face of the step surface between the body and external screw thread 21 of second tubing string 2.Internal thread 11 and outer spiral shell
After line 21 connects, the end face (end face of that one end i.e. provided with internal thread 11) of first tubing string 1 and the step of second tubing string 2
Gapless between face, i.e. step surface are parallel to each other with end face, and contact with each other.By adjusting external screw thread 21 and internal thread 11
Precision, can be achieved first tubing string 1 end face and second tubing string 2 step surface between blind-mate, do not influence to turn to
The overall use of tubing string.
Alternatively it is also possible to which first tubing string 1 is provided with external screw thread, second tubing string 2 is provided with internal thread.
Further, as shown in Fig. 2 first tubing string 1 includes sleeve body 12 and provided with the handle clamp in sleeve body 12
Locking bracket 13.Second tubing string 2 is cylindrical tube.
Specifically, the structure of first tubing string 1 is complex, including sleeve body 12 and handle clamp locking bracket 13, sleeve master
12 substantially cylindrical body of body, handle clamp locking bracket 13 are arranged on outside sleeve body 12, and handle clamp locking bracket 13 is used for and handle
(not shown) connects, and handle is used to adjust steering column anterior-posterior length.
The structure of second tubing string 2 is relatively simple, is cylindrical tube.Therefore, when second tubing string 2 is assembled, can rotate any
Angle, can more preferable space layout.
Further, first tubing string 1 has the first rigidity, and second tubing string 2 has the second rigidity, and the first rigidity is more than second
Rigidity.
First tubing string 1 is because architectural characteristic and functional requirement need to be made up of the material of high rigidity, therefore first tubing string 1 is adopted
Be made of the material of high rigidity, and second tubing string 2 is made of the material of relatively low stiffness, the cost of the material of relatively low stiffness compared with
It is low.Requirement of the steering column to high rigidity and intrinsic frequency had so both been ensure that, has reduced being manufactured into for steering column entirety again
This.
Alternatively, first tubing string 1 is made of aluminum, and second tubing string 2 is formed from steel.
The rigidity and intrinsic frequency of aluminum are high, but cost is also higher；The cost of Steel material is low, but rigidity is not so good as aluminium
Material.Steering column is divided into two parts, aluminium is respectively adopted and steel is made, the advantages of having had aluminium and Steel material concurrently.
Further, the die cast of first tubing string 1, the punch forming of second tubing string 2.
Specifically, first tubing string 1 made of aluminum, by die cast, second tubing string 2 passes through punching made of Steel material
It is molded.
Because the structure of first tubing string 1 is complex, die cast easy to manufacture is utilized；The structure of second tubing string 2 is more
Simply, therefore punch forming can be used.
Further, as shown in Figure 3-4, the minimum wall thickness (MINI W.) of first tubing string 1 is 2-6mm, and the minimum wall thickness (MINI W.) of second tubing string 2 is
1-3mm, the minimum wall thickness (MINI W.) of second tubing string are less than the minimum wall thickness (MINI W.) of first tubing string.
Due to first tubing string die cast, die cast requires to be 2-6mm for the minimum of wall thickness；And second tubing string 2 is adopted
It is made of a steel, minimum wall thickness (MINI W.) 1-3mm.After the wall thickness of second tubing string 2 reduces, it can further reduce arrangement space.
Above-described is only principle and preferred embodiment of the present utility model.It should be pointed out that for the general of this area
For logical technical staff, on the basis of the utility model principle, some other modifications can also be made, also should be regarded as this practicality
New protection domain.
