Description
Technical field
The utility model relates to technical field of automobile accessories, more particularly, to a kind of damper.
Background technique
Damper is generally used for the suspension system of automobile, plays cushioning effect.The effect of damper hanging ring bushing is will to subtract
Shake device and automobile chassis are attached, itself also function to certain shock absorbing effect.The lining of damper hanging ring used at present
Set, usual structure are as follows: be made of internal lining pipe and vulcanization in the vulcanized rubber of internal lining pipe outer circle, vulcanized rubber is pressed directly into when installation
The inner hole of hanging ring.Above structure is primarily present following problems: if structural strength is not high, hanging ring bushing is easy to take off after being pressed into hanging ring
Out, anticreep power output is small, service life is shorter.
The Chinese patent document that application publication number is CN105216570A in the prior art discloses a kind of hanging ring and bushing
Fixed assembly, it is main that using in hanging ring inner wall, groove is set, and corresponding protrusion is set in rubber layer so that protrusion with it is recessed
Slot forms axial limiting to achieve the effect that prevent bushing and hanging ring to be detached from.But above scheme also still remains deficiency；Due to
The setting of protrusion will be clamped in protrusion indentation hanging ring and with groove, then need to carry out protrusion biggish compression, installation is very
It is difficult.To facilitate installation, then require protrusion that there is very big deformability, then reality is not much between rubber layer and hanging ring
Interference effect, still remain the possibility that bushing and hanging ring are detached from.
Utility model content
The purpose of the utility model is to provide a kind of damper, there is bushing to be not easily disconnected from hanging ring, bushing it is easy for installation
Effect.
The above-mentioned purpose of the utility model has the technical scheme that
A kind of damper is equipped with lining in the hanging ring including shock absorber body and the hanging ring for being installed on shock absorber body
Set, the bushing include the left bushing and right bushing for mutually splicing, and the left bushing includes left bushing pipe and is coated on left lining
Left rubber layer outside pipe；The right bushing includes right bushing pipe and the right rubber layer that is coated on outside right bushing pipe；The left bushing pipe and the right side
It is equipped with axial disconnecting prevention structure between bushing pipe, limitation hanging ring axial displacement is equipped between the left rubber layer and right rubber layer and hanging ring
Position limiting structure.
By using above-mentioned technical proposal, since bushing is spliced by left bushing and right bushing, when installation, left bushing could
Be inserted into from the left side of hanging ring, right bushing can be inserted into from the right side of hanging ring, then by left bushing and the splicing of right bushing and left bushing pipe with
Axial disconnecting prevention structure is equipped between right bushing pipe, so that left bushing and right bushing will not be axially disengaging.Then by left rubber layer and
Position limiting structure between right rubber layer and hanging ring generates axial displacement to limit hanging ring relative to bushing, so that hanging ring and lining
There is better fixed effect, hanging ring is not easy to be detached from bushing, and installs and also quite facilitate between set.
The utility model is further arranged to: the axial direction disconnecting prevention structure includes being coaxially disposed in left bushing pipe towards right bushing pipe
Annular dovetail slot on the end face of one end further includes being set to right bushing pipe towards the arc dovetails on the end face of left bushing pipe one end, arc
Shape dovetails and annular dovetail slot are coaxially disposed；It is equipped at the notch of the annular dovetail slot and is lacked for what arc dovetails were inserted into
Mouthful.
By using above-mentioned technical proposal, when left bushing and the splicing of right bushing, by the arc dovetail block alignment of right bushing pipe
The notch of left bushing pipe, arc dovetails are inserted into annular dovetail slot, then relatively rotate left bushing and right bushing, so that arc
Shape dovetails and notch misplace, so that arc dovetails are limited and are installed in annular dovetail slot, to constitute left bushing pipe
With the axial disconnecting prevention structure of right bushing pipe.
The utility model is further arranged to: the arc dovetails and the quantity of notch correspond to two, two notches
Be centrosymmetric setting, and two arc dovetails are centrosymmetric setting.
By using above-mentioned technical proposal, the quantity of notch and arc dovetails corresponds to two, can be in by two
The inner wall of the symmetrical arc dovetails of the heart and annular dovetail slot, which contradicts, constitutes axial disconnecting prevention structure, so that axially loaded is more evenly,
Left bushing pipe and right bushing pipe bonding strength are high.
The utility model is further arranged to: the position limiting structure includes conical opening and the setting for being set to hanging ring both ends
In the tapered portion being adapted in left rubber layer and right rubber layer with conical opening.
By using above-mentioned technical proposal, when left rubber layer is bonded with the conical opening on the left of hanging ring, right rubber layer and hanging ring
When the conical opening fitting on right side, hanging ring is just restricted between left rubber layer and right rubber layer, to be construed as limiting hanging ring axial direction
The position limiting structure of displacement, and the pyramidal structure is more convenient will be in left bushing and right bushing insertion hanging ring.
The utility model is further arranged to: the left rubber layer and right rubber layer are equipped with the limit contradicted with hanging ring end
Position portion.
By using above-mentioned technical proposal, limiting section can stop hanging ring both ends, left bushing and right bushing not
In the case where disengaging, limiting section can play better position-limiting action to hanging ring, so that hanging ring is difficult to be detached from bushing.
The utility model is further arranged to: the limiting section is equipped with the bound edge portion for extending to hanging ring lateral wall.
By using above-mentioned technical proposal, the lateral wall that bound edge portion extends to hanging ring wraps up the both ends of hanging ring, so that hanging
Ring can not be detached from from bushing, have reliable fixed function to hanging ring.
The utility model is further arranged to: the outer wall of the left bushing pipe and right bushing pipe is axially evenly equipped with convex annular
Edge.
By using above-mentioned technical proposal, annular convex edge is set in the outer wall of left bushing pipe and right bushing pipe, so that left rubber layer
It is higher with the fixing intensity of left bushing pipe, right bushing pipe with right rubber layer sulfidization molding when on left bushing pipe and right bushing pipe.
