To achieve the goals above, the utility model provides following technical solution:
Tubing string and gearbox housing assembly have following technical characteristic in automobile steering system provided by the utility model: packet
The interior tubing string and gear box casing fitted together with interference press-fit is included, gear box casing cooperates one end to be arranged with interior tubing string
The convex pipe of the installation for thering is indentation to be installed into interior tubing string.Wherein, setting is respectively corresponded in inner tube column outer wall and the convex pipe outer wall of installation
There are the first installation sheet and the second installation sheet, two installation sheets are bolted to connection.
In the utility model, two installation sheets being bolted to connection are matched with existing interference press-fit, to mention
Height improves the intrinsic frequency and overall stiffness of steering column device.
Preferably, in automobile steering system provided by the utility model in tubing string and gearbox housing assembly, the first peace
Load and the second installation sheet are three-clove style structure, outwardly extending connection sheet that there are three tools, are provided with bolt peace in connection sheet
Fill hole.
Preferably, in automobile steering system provided by the utility model in tubing string and gearbox housing assembly, the first peace
Three connection sheets of load are symmetrical arranged along the central axes of interior tubing string, and three connection sheets of the second installation sheet are along the convex pipe of installation
Axisymmetrical setting.
Preferably, in automobile steering system provided by the utility model in tubing string and gearbox housing assembly, connection sheet
For arc connection sheet.
The action and effect of utility model
According to tubing string and gearbox housing assembly in automobile steering system provided by the utility model, due to inner tube column outer wall
And gear box casing and interior tubing string cooperate to respectively correspond in the convex pipe outer wall of the installation of one end and are provided with the first installation sheet and second
Installation sheet, two installation sheets are bolted to connection, which matches with existing interference press-fit, are increased interior
The bonding strength of tubing string and gear box casing improves steering column in the case where not generating risk to current assembly technology
