Abstract
The utility model discloses a kind of damper outer cylinders, including outer cylinder ontology, the inner cavity edge of the outer cylinder ontology is axially arranged with the first mounting hole for installing support sleeve and the second mounting hole for installing DU bushing, first mounting hole and the second mounting hole are coaxially disposed, and the internal diameter of the second mounting hole is less than the internal diameter of the first mounting hole.The utility model can reduce the press-mounting stroke of DU bushing, and reduce outer cylinder difficulty of processing, not easily cause scrapping for outer cylinder.
Description
Technical field
The utility model relates to damper element fields, design a kind of damper outer cylinder.
Background technique
A kind of automobile damp adjustable is provided application No. is 201410461148.5 Chinese utility model patent to subtract
Shake device.It is as shown in Figure 1 a kind of damper outer tube structure in the prior art, 1 is outer cylinder, and 2 combine for breeches pipe, DU bushing and support
Set 4 is pressed in same hole, and press-mounting stroke is longer, and the cooperation precision of DU bush hole and DU bushing and requires relatively high.Assembly
Shi Rongyi scraps outer cylinder, and cost is caused to waste.
Utility model content
In view of this, reducing press-mounting stroke the purpose of this utility model is to provide a kind of damper outer cylinder, not easily causing
Scrapping for outer cylinder, has saved cost, improves efficiency.
The inner cavity edge of the utility model damper outer cylinder, including outer cylinder ontology, the outer cylinder ontology is axially arranged with for pacifying
The first mounting hole of support sleeve and the second mounting hole for installing DU bushing are filled, first mounting hole and the second mounting hole are same
Axis setting, and the internal diameter of the second mounting hole is less than the internal diameter of the first mounting hole.
Further, second mounting hole is arranged far from the side of outer cylinder ontology press fitting mouth.
Further, first step is equipped in the outer cylinder ontology, the first step is for DU bushing far from press fitting mouth one
The positioning of side end face.
Further, second step is equipped in the outer cylinder ontology, the second step is used to support set far from press fitting mouth one
The positioning of side end face.
Further, the surface roughness value of first mounting hole is greater than the roughness value of the second mounting hole.
Further, the range of surface roughness of first mounting hole is Ra3.2~Ra6.3.
Further, the surface roughness of second mounting hole is Ra1.6~Ra3.2.
The utility model has the beneficial effects that the utility model can reduce DU bushing press-mounting stroke, and reduces outer cylinder and add
Work difficulty does not easily cause scrapping for outer cylinder, has saved cost, improves efficiency.
Detailed description of the invention
The utility model is further described with reference to the accompanying drawings and examples:
Fig. 1 is the assembling schematic diagram in prior art outer cylinder；
Fig. 2 is the structural schematic diagram of the utility model outer cylinder.
Specific embodiment
As shown in Fig. 2, the utility model damper outer cylinder, including outer cylinder ontology 1, the inner cavity of the outer cylinder ontology 1 is along axis
To the second mounting hole 7 being equipped with for installing the first mounting hole 6 of support sleeve and for installing DU bushing, first mounting hole
6 and second mounting hole 7 be coaxially disposed, and the internal diameter of the second mounting hole 7 is less than the internal diameter of the first mounting hole 6.First mounting hole 6 with
Second mounting hole 7 is disposed adjacent, and the inner end of the first mounting hole 6 is arranged in the second mounting hole 7, by the first mounting hole 6
It is provided separately with the second mounting hole 7, DU bushing is during press fitting, without being pressed together with support sleeve, and due in the two
Diameter is different, reduces the press-mounting stroke of DU bushing.
In the present embodiment, the second mounting hole 7 is arranged far from the side that outer cylinder ontology 1 is pressed mouth.Outer cylinder ontology 1 is left in figure
End is press fitting mouth, and the second mounting hole 7 is arranged far from the side of press fitting mouth, in assembling process, is first pressed DU bushing, then be pressed branch
Support set.
In the present embodiment, first step 5 is equipped in outer cylinder ontology 1, first step 5 is for DU bushing far from press fitting mouth side
The positioning of end face.DU bushing positions the right end of DU bushing far from press fitting one side end face of mouth, that is, DU bushing right end.
In the present embodiment, second step 8 is equipped in outer cylinder ontology 1, second step 8 is used to support set far from press fitting mouth side
The positioning of end face.The right side of support sleeve is positioned.During press fitting, by DU bushing press-mounting in the second mounting hole 7
Kong Shi, right side are positioned by first step 5, and after being pressed support sleeve, the right side of support sleeve is positioned by second step 8, this
It cannot influence each other axially mutually between sample support sleeve and DU bushing, not easily cause outer cylinder to scrap during press fitting, improve
Product quality.
In the present embodiment, the surface roughness value of the first mounting hole 6 is greater than the roughness value of the second mounting hole 7.
In the present embodiment, the range of surface roughness of the first mounting hole 6 is Ra3.2~Ra6.3.Preferably, the present embodiment
The roughness of first mounting hole 6 is Ra6.3.The surface roughness of second mounting hole 7 is Ra1.6~Ra3.2.Preferably, this reality
The roughness for applying the second mounting hole of example 7 is Ra1.6.Using both roughness, can guarantee very well while save the cost
Installation quality.The present embodiment separates the second mounting hole 7 and the first mounting hole 6, and it is too long to prevent press-mounting stroke, leads to product
Scrap phenomenon.Product difficulty of processing is effectively reduced, improves product assembly efficiency, reduces cost.
Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this
The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model
It encloses, should all cover in the scope of the claims of the utility model.
