Embodiment 1 please refers to Fig. 2-Fig. 6, and the present embodiment provides a kind of Anti-extrusion bushings, including are successively arranged from inside to outside
Bushing inner tube 23, bush body 22 and bushing outer tube 21, the bushing outer tube 21 have opposite first end and second end,
The internal diameter of the first end end is less than the internal diameter of the second end end, the outer surface of the bush body 22 and the bushing
The inner surface of outer tube 21 fits.The bush body is made of rubber.The bushing inner tube 23 with subframe for connecting.
The present embodiment by the way that the setting of the internal diameter of first end end is less than the internal diameter of second end end, thus increase bushing from
Abjection power in second end to the first extreme direction.Bushing is set to be subjected to bigger power in this direction without bushing occurs
The case where ontology 22 and bushing outer tube 21 are detached from.When in use, by the direction of brake weight and second end to the first extreme direction phase
Match, so that bushing be allow to be subjected to the bigger power on brake weight direction, prevent bushing from deviating from along brake Impact direction part,
Make to interfere at bushing and subframe upper bushing mounting surface, causes vehicle abnormal sound.
Further, in the preferred scheme of the present embodiment, the bushing outer tube 21 includes the first pipe portion 211 and second
Pipe portion 222, first pipe portion 211 and second pipe portion 222 are straight pipe structure, and first pipe portion 211 is far from institute
The one end for stating the second pipe portion 222 is the first end, and the one end of second pipe portion 222 far from first pipe portion 211 is institute
Second end is stated, the internal diameter of first pipe portion 211 is less than the internal diameter of second pipe portion 222.
In actual implementation, if the internal diameter of bushing outer tube 21 is designed to gradual change, although can increase from second end to
Abjection power on one extreme direction, but can also reduce the abjection power on from first end to the second extreme direction accordingly.And the present embodiment
In preferred scheme, by the way that bushing outer tube 21 is arranged to the pipe portion with two different inner diameters, make the inner wall of bushing outer tube 21
It is whole or horizontal, the abjection power in first end to the second extreme direction would not be made to reduce, and the first pipe portion 211 and the second pipe
222 junction of portion forms a step-like structure, this step-like structure can make the abjection in second end to the first extreme direction
Power increases.Anti-extrusion bushing provided in this embodiment is allowed not reduce the abjection power in first end to the second extreme direction to realize
In the case where, the abjection power increased in second end to the first extreme direction increases.
In the specific implementation, the outer surface of bushing outer tube 21 can then select straight tube-like or and inner surface according to actual needs
Identical structure.The outer diameter of i.e. described first pipe portion 211 is equal with the outer diameter of second pipe portion 222.
Or the outer diameter of first pipe portion 211 is less than the outer diameter of second pipe portion 222.
When the outer diameter of first pipe portion 211 is equal with the second pipe portion 222, i.e., the outer surface of bushing outer tube 21 with
The shape of existing bushing is identical, installs and uses Anti-extrusion bushing provided in this embodiment directly with existing control arm,
Without being adjusted modification to control arm again.
As shown in Figure 5 and Figure 6, when the outer diameter of first pipe portion 211 is less than the outer diameter of second pipe portion 222, i.e.,
The outer surface of bushing outer tube 21 is similar to inner surface configuration, also forms a step structure.It is that control arm installation makes at this time
Used time needs the inner surface for the control arm outer tube for being used to install Anti-extrusion bushing to control arm to be arranged to outer with bushing outer tube 21
The identical structure in surface.Although can also increase accordingly Anti-extrusion lining in this way, needing also to modify to control arm outer tube
Set and abjection power of the control arm outer tube in second end to the first extreme direction.
Further, in the present embodiment, to keep the effect of Anti-extrusion bushing receiving abjection power more preferable, first pipe portion
The ratio between 211 internal diameter and the internal diameter of second pipe portion 222 are 1:1.2-1:1.5.The outer diameter of first pipe portion 211 with it is described
The ratio between outer diameter of second pipe portion 222 is 1:1.2-1:1.5.
Fig. 1 and Fig. 5 are please referred to, the present embodiment also provides a kind of control arm of anti-bushing abjection, including control arm 1 and bushing
2, the bushing is Anti-extrusion bushing described in any of the above embodiments, and the control arm 1 has bushing installation end 11, the bushing
Installation end 11 is fixedly installed control arm outer tube 12, and the bushing 2 is set in the control arm outer tube 12, outside the control arm
The inner surface of pipe 12 and the outer surface of the bushing outer tube 21 fit.In the present embodiment, the control arm outer tube 12 and described
Bushing outer tube 21 is made of steel, and the outer surface mistake of the inner surface of the control arm outer tube 12 and the bushing outer tube 21
It is full of cooperation.
When the outer diameter of first pipe portion 211 is less than the outer diameter of second pipe portion 222, the control arm outer tube 12 is wrapped
Third pipe portion 121 and the 4th pipe portion 122 are included, the third pipe portion 121 and the 4th pipe portion 122 are straight pipe structure, described
The inner surface of third pipe portion 121 and the outer surface of first pipe portion 211 fit, the inner surface of the 4th pipe portion 122 with
The outer surface of second pipe portion 222 fits, and the outer diameter of the third pipe portion 121 is less than the outer diameter of the 4th pipe portion 122.
The inner surface of the control arm outer tube 12 is set to form a step structure as the outer surface of the bushing outer tube 21, to increase
Add the abjection power of Anti-extrusion bushing and control arm outer tube 12 in second end to the first extreme direction.
Further, in another embodiment, the outer surface of the bush body 22 is equipped with several hemispherical projections
221, the inner surface of the bushing outer tube 21 is equipped with hemispherical groove corresponding with the hemispherical projections 221.The hemispherical
Protrusion 221 and the hemispherical groove match, and can further increase bush body 22 and bushing outer tube 21 along the bushing
Two-way abjection power on length direction.
Further, in another embodiment, the interior table of the outer surface of the bush body 22 and the bushing outer tube 21
Face is frosting.Two rubbing surfaces, which match, can further increase bush body 22 and bushing outer tube 21 along the bushing
Two-way abjection power on length direction.
Above description is merely a prefered embodiment of the utility model, is not intended to limit the utility model, for
For those skilled in the art, various modifications and changes may be made to the present invention.All spirit and original in the utility model
Within then, any modification, equivalent replacement, improvement and so on be should be included within the scope of protection of this utility model.
