Description
Technical field
The utility model belongs to technical field of automobile accessories, is related to a kind of bushing, in particular to a kind of automobile control arm is used
Bushing.
Background technique
Guiding and force transfer element of the automobile control arm as automobile suspension system will act at the various power transmitting on wheel
To vehicle body, while guaranteeing that wheel is moved by certain track.Existing automobile control arm bushing includes external bushing and neck bush, outside
Bushing is that the aluminium alloy of tubular is made later, and neck bush is made of rubber material, and integral strength is preferable, but cushion performance is still
It is not ideal enough, drawing, compressive load and shock loading that wheel passes over cannot be effectively unloaded, service life is influenced.
In view of the above problems, people devise various automobile control arm bushings, some are also applied
Patent, such as Chinese documents and materials disclose in a kind of rear axle multi-link structure for connecting the bushing of control arm and wheel stand
[application number: 201510757932.5；Application publication number: CN105240397A] comprising radially set gradually from inside to outside
Neck bush, middle bushing and external bushing, what neck bush, middle bushing and external bushing were made of metal, middle bushing and neck bush
It is equipped with the inner rubber layer of annular between radial direction, the outer rubber layer of annular is equipped between external bushing and the radial direction of middle bushing, in middle lining
The axial ends of set, inner rubber layer and outer rubber layer are linked together, and the shape of neck bush axial ends is to neck bush axial direction
The toroidal that middle part is shunk.
Increase the lower end of neck bush in above-mentioned rear axle multi-link structure for connecting the bushing of control arm and wheel stand
Contact area between face and lower control arm reduces the footprint pressure between neck bush lower end surface and lower control arm, prevents liner
Contact surface between the lower end surface and lower control arm of set fails because being in contact fatigue, but its manufacturing cost is high, three layers of gold
Belonging to bushing makes its rigid support effect good, but will affect cushion performance, cannot effectively buffer drawing, pressure that wheel passes over
Load and shock loading, in addition external bushing and neck bush twisting resistance are ineffective, and long-time service can deflect, and influence using effect
Fruit.
Summary of the invention

In a kind of above-mentioned automobile control arm bushing, rubber layer setting is stretched out at the both ends of the bushing inner tube,
The both ends of the bushing inner end are embedded with retainer ring, have between buffering between the retainer ring and corresponding rubber layer end face
Away from.Bushing inner tube and the contact area of connecting rod in this way is more, and power transmitting is stablized, when bushing inner tube is by axial tension, rubber layer
Axially loaded and deformation, play shock absorbing effect, and when axial tension is larger, retainer ring contacts at corresponding rubber layer end face,
Play the role of barrier effect, also functions to pulling force between transmitting bushing inner tube and rubber layer, pulling force is transferred to rubber layer end face
So that rubber layer entirety stress extends service life so that bushing inner tube and rubber layer junction be avoided to tear.
In a kind of above-mentioned automobile control arm bushing, the bushing outer tube has multiple connections extended radially through
Hole, the rubber layer, which has, to be full of in the interconnecting piece in connecting hole.The setting of connecting hole is so that rubber layer and bushing outer tube connect
It connects securely, and when bushing outer tube is in interference fit in control arm, interconnecting piece increases frictional force, so that bushing outer tube and control
Arm connectivity robustness is high, and bushing outer tube not will receive torsion and deflect.
In a kind of above-mentioned automobile control arm bushing, the both ends of the connecting column are stretched out outside rubber layer and bushing
Pipe setting.Connecting column is when vulcanization is processed in this way convenient for positioning, so that easy to process.
Compared with prior art, the absorbing shock performance of this automobile control arm bushing is good, and torsion stiffness is good, and rubber layer is anti-
Torque capability, rubber layer is not easily damaged, long service life.
