The problem that the crumple stroke of tubing string assembly is less.Another object of the present utility model is to provide one and comprises
The automobile of this column assy.
For achieving the above object, this utility model provides following technical scheme:
A kind of column assy, it includes lower column jecket, reducing gear upper end cover and is arranged on upper prop
Steering spindle in pipe, integrally formed with the lobe that press-fits of hollow, institute on described reducing gear upper end cover
State the bearing of trend press-fiting lobe identical with the bearing of trend of described lower column jecket；Described press-fit lobe
The inner surface interference fit of outer surface and described lower column jecket；The diameter of the described endoporus press-fiting lobe
External diameter more than described steering spindle.
Preferably, press-fit in lobe the one end away from described reducing gear upper end cover described in and there is arc
Guide frame.
Preferably, in described steering spindle near described in press-fit lobe the outer surface of one end be that taper is led
To face.
Preferably, the inner surface of described lower column jecket being provided with spacing preiection, described spacing preiection is used for
Keep off mutually with described one end press-fited in lobe away from described reducing gear upper end cover and connecing.
A kind of automobile, it includes that column assy, described column assy are any of the above-described institute
The column assy stated.
The beneficial effects of the utility model are:
Column assy of the present utility model, the diameter of its endoporus press-fiting lobe is more than steering spindle
External diameter so that steering spindle can successfully penetrate in the endoporus press-fiting lobe, without impact turn
To the crumple stroke of tubing string assembly, only need to make to press-fit outside lobe in this column assy simultaneously
Surface and the inner surface interference fit of lower column jecket, it becomes possible to realize both firm connections, eliminate and adopt
With when being welded to connect produce weld seam so that this column assy when crumple, the lower end of upper column jecket
Can fit with reducing gear upper end cover, thus effectively increase the crumple of this column assy
Stroke, and then greatly reduce the injury suffered by driver.
Automobile of the present utility model includes above-mentioned column assy, owing to above-mentioned column assy has
Having above-mentioned beneficial effect, the automobile comprising above-mentioned column assy also should have corresponding beneficial effect.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present application or technical scheme of the prior art, below by right
In embodiment, the required accompanying drawing used is briefly described, and will be in conjunction with accompanying drawing to of the present utility model
Specific embodiment is described in further detail, wherein
Fig. 1 is existing lower column jecket schematic diagram when being connected with reducing gear upper end cover；
The schematic diagram of the reducing gear upper end cover that Fig. 2 provides for this utility model embodiment；
Cuing open when Fig. 3 is connected with reducing gear upper end cover for the lower column jecket that this utility model embodiment provides
View.
Labelling in accompanying drawing:
11, lower column jecket 12, reducing gear upper end cover 13, weld seam 21, reducing gear upper end cover
22, lobe 23, arcuate guide structure 24, endoporus 31, lower column jecket are press-fited
41, upper column jecket 51, steering spindle 52, tapered guide surface
Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical solution of the utility model, below will knot
Close specific embodiment this programme is discussed in detail further.
As shown in Figure 2 to Figure 3, this utility model embodiment provides a kind of column assy, its
Including lower column jecket 31, reducing gear upper end cover 21 and the steering spindle 51 being arranged in upper column jecket, its
Press-fit lobe 22 integrally formed with hollow on middle reducing gear upper end cover 21, press-fit lobe 22
Bearing of trend identical with the bearing of trend of lower column jecket 31；Press-fit outer surface and the lower prop of lobe 22
The inner surface interference fit of pipe 31；Press-fit the diameter of endoporus 24 of lobe 22 more than steering spindle 51
External diameter.
The column assy that this utility model embodiment provides, it press-fits the endoporus 24 of lobe 22
