Abstract
The utility model is related to a kind of automobile rubber shock absorbing bushings, belong to automobile shock bushing technical field.It includes metal inner pipe, rubber bodies and plastic outer tube, and metal inner pipe center outer surface is equipped with the bulge-structure of circular ring shape, and bulge-structure is stretched into rubber bodies；The front and rear end margin of plastic outer tube is equipped with closing-in structure inwardly.The utility model is simple in structure, compact, reasonable, and plastic outer tube port, which is shunk, effectively to prevent rubber bodies from coming off with plastic outer tube；Metal inner pipe middle projective structure ensures that the rubber bodies after vulcanization do not come off with metal inner pipe；Two semicircle plastic outer tubes effectively reduce processing cost.
Description
Technical field
The utility model is related to a kind of automobile rubber shock absorbing bushings, belong to automobile shock bushing technical field.
Background technology
With economic development, people's living standards continue to improve, people the entirety of vehicle is required it is higher and higher,
Efficient and convenient and comfortableization is increasingly pursued, damping is widely used on automobile component, is rigidly connected to from automobile is incipient
Existing rubber connection or even hydraulic shock-absorption connection, cushion technique are more and more applied on automobile.
In the prior art, automobile frame rubber shock-absorbing bushing generally comprises metal shell, intermediate rubber body and inner tube three
Component, three components are joined together to form complete bushing, traditional technique be directly metal shell and inner tube in
Between rubber bodies link together, such structure is easily axially deviate from, and rigidity difficulty tune, in order to enhance the comfort of automobile, need
Increase the rigidity of its vehicle frame rubber shock-absorbing bushing, it is therefore desirable to design a rubber shock-absorbing bushing that can adjust rigidity.
Invention content
In place of the purpose of this utility model is to overcome above-mentioned deficiency, so as to provide a kind of automobile rubber shock absorbing bushing, greatly
The big structural strength for improving bushing, processing are simple and of low cost.
According to technical solution provided by the utility model, a kind of automobile rubber shock absorbing bushing includes metal inner pipe, rubber bodies
And plastic outer tube, metal inner pipe is located at plastic outer tube center, filled rubber body between metal inner pipe and plastic outer tube, and leads to
It crosses rubber bodies metal inner pipe and plastic outer tube link into an integrated entity, it is characterized in that：Metal inner pipe center outer surface is equipped with circular ring shape
Bulge-structure, bulge-structure stretched into rubber bodies；The front and rear end margin of plastic outer tube is equipped with closing-in structure inwardly.
Further, rubber bodies cover outer surface, the modeling of entire metal inner pipe with metal inner pipe, plastic outer tube connecting end surface
Expect the inner surface of outer tube.
Further, plastic outer tube includes two symmetrical semicircle tube bodies, and plastic outer tube uses injection molding.
Compared with the prior art the utility model has the following advantages：
The utility model is simple in structure, compact, reasonable, and plastic outer tube port, which is shunk, can effectively prevent rubber bodies and modeling
Material outer tube comes off；Metal inner pipe middle projective structure ensures that the rubber bodies after vulcanization do not come off with metal inner pipe；Two semicircles
Shape plastic outer tube effectively reduces processing cost.
Description of the drawings
Fig. 1 is the half-sectional structure chart of the utility model.
Reference sign：1- metal inner pipes, 2- rubber bodies, 3- plastic outer tubes, 4- bulge-structures, 5- closing-in structures.
Specific embodiment
The utility model will be further described with reference to the embodiment in attached drawing below：
As shown in Figure 1, the utility model mainly includes metal inner pipe 1, rubber bodies 2 and plastic outer tube 3, metal inner pipe 1
In 3 center of plastic outer tube, filled rubber body 2 between metal inner pipe 1 and plastic outer tube 3, and pass through rubber bodies 2 will be in metal
Pipe 1 and plastic outer tube 3 link into an integrated entity.
1 center outer surface of metal inner pipe is equipped with the bulge-structure 4 of circular ring shape, and bulge-structure 4 is stretched into rubber bodies 2, protrusion
Structure 4 improves the bonding strength of rubber bodies and metal inner pipe.
The front and rear end margin of plastic outer tube 3 is equipped with closing-in structure 5 inwardly, and closing-in structure 5 improves rubber bodies and plastics
The bonding strength of outer tube 3.
Plastic outer tube 3 includes two symmetrical semicircle tube bodies, and plastic outer tube 3 uses injection molding.
The rubber bodies 2 cover the outer surface of entire metal inner pipe 1, modeling with metal inner pipe 1,3 connecting end surface of plastic outer tube
Expect the inner surface of outer tube 3.
Utility model works principle：The damping for being used as rubber shock-absorbing bushing by the super-elastic that rubber bodies have is situated between
Matter is connected the matched metal inner pipe of the rubber bodies after vulcanization and plastic outer tube composition for alleviating rubber shock-absorbing bushing
The vibration of body part reduces the noise generated in the operational process of automobile, improves the comfort of driver and passenger.
The utility model is capable of providing torsion and the damping of vertical direction, and for Bit andits control axially and radially, makes
Corresponding rigidity requirement is can reach, and torsion stiffness also can obtain effective control with relatively low rubber hardness, improve product matter
Amount and damping effect.
