Description
Technical field
It the utility model is related to a kind of attachment structure of automotive steering oil pipe and rubber tube.
Background technology
The attachment structure of existing automotive steering oil pipe and rubber tube is as follows：The pipe shaft of automotive steering oil pipe is provided with first
The annular shaft shoulder, the end of automotive steering oil pipe are provided with the second annular shaft shoulder, during installation, by rubber sleeve on automotive steering oil pipe
And between the first annular shaft shoulder and the second annular shaft shoulder, the rubber that is pointed between the first annular shaft shoulder and the second annular shaft shoulder
The mode of withholding of sebific duct ecto-entad makes rubber tube deform, and the first annular shaft shoulder is formed with the second annular shaft shoulder to rubber tube
Axial limiting, groove is formed in the outside wall surface of rubber tube, the rubber tube after deformation is combined closely with steering oil pipe, so as to turning
Formed and sealed to oil pipe.
However, under the work of automotive steering oil pipe is generally operational in the environment of cryogenic high pressure, at low ambient temperatures, rubber
Pipe can follow the string and become fragile, and cause to produce gap between rubber tube and automotive steering oil pipe, so as to cause oil to be let out from gap location
Leakage.
The content of the invention
The purpose of this utility model is to provide a kind of company of the automotive steering oil pipe that oil can be prevented to reveal and rubber tube
Binding structure.
The technical scheme for solving above-mentioned technical problem is as follows：
The attachment structure of automotive steering oil pipe and rubber tube, including automotive steering oil pipe, rubber tube, automotive steering oil pipe
Pipe shaft is provided with the first limiting section, and the end of automotive steering oil pipe is provided with the second limiting section, positioned at first limiting section and
Annular projection is arranged at intervals with the pipe shaft of automotive steering oil pipe between second limiting section, rubber sleeve is in automotive steering oil pipe
On, after rubber tube is fixed on automotive steering oil pipe by way of withholding, the annular projection is automatic in the case where withholding active force
Ground is embedded into inside the rubber tube from the internal face of rubber tube.
Further, in addition to sleeve pipe, the sleeve pipe is enclosed on rubber tube and is fixed as one with rubber tube with withholding.
Further, described sleeve pipe is made up of metal material.
Further, the height of annular projection is more than or equal to 0.1mm.
Further, the surface of the annular projection is arc surface.
Further, the axial direction of the annular projection and automotive steering oil pipe is axially in parallel, or the axle of annular projection
To having angle between the axial direction of automotive steering oil pipe.
The advantages of the utility model is：After rubber tube is fixed on automotive steering oil pipe by way of withholding, the ring
Shape projection is automatically embedded into inside the rubber tube in the case where withholding active force from the internal face of rubber tube, and such structure causes
Between rubber tube and automotive steering oil pipe, the sealing ring of several ring-types is formd, even if rubber tube can follow the string and become fragile,
Cause to produce gap between rubber tube and automotive steering oil pipe, under the stop of these several sealing rings, prevent letting out for oil
Leakage.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the schematic diagram of the automotive steering oil pipe in the utility model；
Fig. 3 is the partial enlarged drawing of automotive steering oil pipe.
Embodiment
As shown in Figure 1 to Figure 3, the attachment structure of the automotive steering oil pipe of the new type of this practicality and rubber tube, including automobile
Steering oil pipe 1, rubber tube 2, the pipe shaft of automotive steering oil pipe 1 are provided with the first limiting section 1a, and the end of automotive steering oil pipe 1 is set
There is the second limiting section 1b, in the pipe shaft of the automotive steering oil pipe 1 between the first limiting section 1a and the second limiting section 1b
On be arranged at intervals with annular projection 1c, annular projection 1c surface is arc surface, annular projection 1c axial direction and motor turning oil
Pipe it is axially in parallel, or there is angle between annular projection 1c axial direction and the axial direction of automotive steering oil pipe.Annular projection 1c
Height be more than or equal to 0.1mm, annular projection 1c height is less than the wall thickness of rubber tube 2, in order to avoid withholding over-pressed middle ring
Shape projection 1c stabs out rubber tube, for example, the wall thickness of rubber tube 2 is 3.7mm, then annular projection code 1c height maxima does not surpass
Cross 1.8mm.Rubber tube 2 is enclosed on automotive steering oil pipe 1, and rubber tube 2 is fixed on by way of withholding on automotive steering oil pipe 1
Afterwards, the annular projection 1c is automatically embedded into inside the rubber tube 2 in the case where withholding active force from the internal face of rubber tube 2.
Also include sleeve pipe 3, the sleeve pipe 3 is enclosed on rubber tube 2 and is fixed as one with rubber tube 2 with withholding.Described sleeve pipe 2
By being preferentially made from metal material, because rubber tube 2 is to be combined into one with automotive steering oil pipe 1 by way of withholding deformation
Body, the package action formed by the sleeve pipe 3 after deformation to rubber tube 2, prevents the bounce-back of rubber tube 2, that is, ensure rubber tube 2 with
The reliability combined between automotive steering oil pipe 1.
