It connects in rubber on bushing, bushing is interference fitted in casing and rubber.This structure and connection type are jolted in automobile,
When internal surface of casing generates the thrust of an axial direction, so that bushing in casing and rubber is generated sliding, be easy to make casing from rear damping
It falls off on device bushing, to influence the service life of damper.
Utility model content
The purpose of the utility model is to provide a kind of automobile rear damper bush Assembly, casing is difficult to from rear shock absorber bushing
On fall off, extend the service life of damper.
The above-mentioned purpose of the utility model has the technical scheme that
A kind of automobile rear damper bush Assembly, including bushing and the casing being connected on damper, bushing includes liner
Set and middle bushing, the middle bushing are rubber material, and the both ends of the middle bushing are equipped with flange, and the flange covers sleeve end
Lateral wall in casing is simultaneously swept along in face, and the lateral wall of described sleeve pipe is equipped with the caulking groove of annular, and the outer of the flange is equipped with tightening
Circle, the tightening ring are embedded in caulking groove, and the outer wall of described sleeve pipe is equipped with the position limiting structure for stopping caulking groove to be open.
It is main slippage point by using above-mentioned technical proposal, between middle bushing and casing, this programme passes through in middle lining
It covers both ends and flange is set, swept along by flange to the outer wall of casing, and flange is fixed by tightening ring insertion caulking groove, so that
The both ends of middle bushing are fixed on casing, as long as generating relative displacement between casing and middle bushing, flange and tightening ring with
Connection structure between caulking groove can generate limitation to above-mentioned displacement, and position limiting structure can stop tightening ring to deviate from caulking groove, so that
Casing is difficult to be detached from from bushing, improves service life.
The utility model is further arranged to: the position limiting structure includes threaded portion and the rotation that sleeve outer wall is arranged in
It is connected to the sliding sleeve of threaded portion, is formed and is contradicted with tightening ring when the sliding sleeve is moved at caulking groove, the sliding sleeve and sleeve outer wall
Between be equipped with gap for accommodating flange.
By using above-mentioned technical proposal, sliding sleeve works as shifting by rotating in threaded portion to generate movement in sleeve outer wall
When moving to caulking groove opening, caulking groove opening is blocked, so that tightening ring can not be deviate from from caulking groove.And the setting in gap is so that sliding
The sliding of set not will receive the blocking of flange.
The utility model is further arranged to: the radial section of the caulking groove is U-shaped；The caulking groove is in incline to cannula tip
Tiltedly setting.
By using above-mentioned technical proposal, when tightening ring is embedded in caulking groove, since caulking groove is in cannula tip side
Angle between wall and sleeve outer wall is acute angle, and the resistance that tightening ring is deviate from from caulking groove is larger, so that the fixation of tightening ring is more
Reliably.
The utility model is further arranged to: the joining place of the caulking groove and sleeve outer wall is rounding off.
By using above-mentioned technical proposal, when tightening ring is embedded in caulking groove, flange contacts at the rank of caulking groove and sleeve outer wall
Place is met, rounding off structure will be set as at this, so that flange is hardly damaged.
The utility model is further arranged to: the outer wall edge of the neck bush is axially arranged with several annular convex edges；The ring
The radial section of shape convex edge is semicircle.
By using above-mentioned technical proposal, after sulfidization molding, annular convex edge and middle bushing are mutual for middle bushing and neck bush
Occlusion, can be improved the bonding strength between neck bush and middle bushing.

Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment:
A kind of automobile rear damper bush Assembly, such as Fig. 1, including casing 1, casing 1 are used to be fixed on automobile absorber,
It further include the bushing 2 being made of neck bush 3 and middle bushing 2, neck bush 3 is metal tube, and middle bushing 2 is integrated in vulcanization is fixed on
The rubber layer of bushing 3.The outer wall of neck bush 3 is uniformly provided with several annular convex edges 5 along axial direction, and the radial section of annular convex edge 5 is
Semicircle, in neck bush 3 and fixed middle bushing 2 vulcanization for improving the fixing intensity of neck bush 3 Yu middle bushing 2.
As shown in Fig. 2, the both ends of middle bushing 2 are equipped with flange 6, the end of flange 6 is equipped with tightening ring 7, tightening ring 7 it is straight
Diameter is greater than the thickness of flange 6, and flange 6 and tightening ring 7 are shaped on middle bushing 2.As shown in Figure 1, by neck bush 3 and in
