Abstract
The utility model discloses one kind to control arm bush, including interior pipe fitting, outer tube member, the middle skeleton being arranged between interior pipe fitting and outer tube member and vulcanization in middle skeleton and rubber parts Nian Jie with interior pipe fitting and outer tube member, middle skeleton, which is provided with, allows the glue feeding opening of rubber entrance.Control arm bush of the present utility model, set glue feeding opening to connect rubber parts in middle skeleton, the pulling-out force of rubber is improved, so as to improve the endurance quality of bushing and axial pulling-out force.
Description
Technical field
The utility model belongs to vehicle chassis technical field, specifically, the utility model is related to a kind of control arm bush.
Background technology
Bushing is the elastic component for connecting the chassis part such as the control arm of vehicle and subframe, has and alleviates road not
Flat, vehicle, which accelerates, and braking is caused impacts, and ensures occupant comfort, the characteristic of control stability.Because bushing is in vehicle fortune
Repeated deformation state is generally in row, fatigue damage is more serious, improves its durability and becomes as each main engine plants and supplier's work
The most important thing of work.
In order to ensure to increase the radial rigidity of bushing under the premise of axial rigidity and torsional rigidity are less, in the prior art
It is by adding middle skeleton structure in bushing inner tube, such a structure can cause glue amount to reduce, the meeting under larger twisting conditions
There are the failures such as degumming, colloidal sol, cracking, poor durability, cause vehicle that the failures such as abnormal sound occur, trigger client's complaint.
Utility model content
The utility model is intended at least solve one of technical problem present in prior art.Therefore, the utility model carries
Arm bush is controlled for one kind, it is therefore an objective to improves endurance quality.
In order to solve the above-mentioned technical problem, technical scheme is used by the utility model：Control arm bush, including inner tube
Part, outer tube member, the middle skeleton being arranged between interior pipe fitting and outer tube member and vulcanization in middle skeleton and with interior pipe fitting and outer tube
The rubber parts of part bonding, middle skeleton are provided with the glue feeding opening for allowing rubber to enter.
The middle skeleton is located at the inside of rubber parts, cavity of the rubber parts between said inner tube part and the outer tube member
In.
The middle skeleton is both ends open, the cirque structure of inner hollow, and the glue feeding opening is to be arranged at middle skeleton
Through hole in side wall.
The glue feeding opening is circular port, a diameter of 3~10mm of glue feeding opening.
The glue feeding opening is square opening.
The glue feeding opening is multiple to be circumferentially uniformly arranged in the side wall of the middle skeleton.
The length of said inner tube part is more than the length of the outer tube member and the middle skeleton.
Control arm bush of the present utility model, set glue feeding opening to connect rubber parts in middle skeleton, improve the drawing of rubber
De- power, so as to improve the endurance quality of bushing and axial pulling-out force.

Embodiment
Below against accompanying drawing, by the description to embodiment, specific embodiment of the present utility model is made further detailed
Thin explanation, it is therefore an objective to help those skilled in the art have to design of the present utility model, technical scheme it is more complete, accurate and
Deep understanding, and contribute to its implementation.
As shown in Figures 1 to 5, the utility model provides a kind of control arm bush, including interior pipe fitting 1, outer tube member 4, sets
The middle skeleton 2 and vulcanization being placed between interior pipe fitting 1 and outer tube member 4 vulcanize in middle skeleton 2 and with interior pipe fitting 1 and outer tube member 4
The rubber parts 3 of bonding, middle skeleton 2 are provided with the glue feeding opening 5 for allowing rubber to enter.
Specifically, as shown in Figures 1 to 5, interior pipe fitting 1, outer tube member 4 and middle skeleton 2 are both ends open, inner hollow
Cirque structure, interior pipe fitting 1, outer tube member 4 and middle skeleton 2 is are coaxially disposed.Middle skeleton 2 is located at the inside of rubber parts 3, rubber
Part 3 is fully wrapped around by middle skeleton 2, in cavity of the rubber parts 3 between interior pipe fitting 1 and outer tube member 4.And the length of interior pipe fitting 1
For degree more than outer tube member 4 and the length of middle skeleton 2, the diameter of outer tube member 4 is more than the diameter of interior pipe fitting 1, the two end portions of interior pipe fitting 1
Not Wei Yu outer tube member 4 side, the length scale that the both ends of interior pipe fitting 1 are extend out to outside outer tube member 4 is identical.
As shown in Figures 2 and 3, glue feeding opening 5 in the annular side wall of middle skeleton 2 through the through hole set, during vulcanization
Rubber passes through glue feeding opening 5 so that and the part that rubber parts 3 is located inside and outside middle skeleton 2 is connected by glue feeding opening 5, so that
The connection of outer rubber in strengthening under big twisting conditions, and then the endurance quality of bushing and axial pulling-out force can be obtained significantly
Lifting.
The shape of glue feeding opening 5 has a variety of, can be circular port or square opening.As shown in Figures 2 and 3, glue feeding opening 5 is preferably
Circular port, the size of glue feeding opening 5 typically determine that the diameter of glue feeding opening 5 is preferably 3 according to the size of middle skeleton 2 and radial rigidity
~10mm.
Glue feeding opening 5 is multiple to be circumferentially uniformly arranged in the side wall of middle skeleton 2, and glue feeding opening 5 is in the side of middle skeleton 2
Be also provided with vertically multiple on wall, i.e., glue feeding opening 5 sets multi-turn in the side wall of middle skeleton 2, each uniform multiple glue feeding openings 5 of circle,
So as to further lift the performance of bushing.As preferable, glue feeding opening 5 is in the side wall of middle skeleton 2 to be circumferentially uniform
Set 4~8.
As preferable, middle skeleton 2 can use the technique of rolling plate into longitudinal be made, so as to reduce process costs and be manufactured into
This.
The utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, as long as employing changing for the various unsubstantialities that methodology and technical scheme of the present utility model are carried out
Enter, or it is not improved by it is of the present utility model design and technical scheme directly apply to other occasions, in the utility model
Protection domain within.
