Abstract
The present invention relates to a kind of automobile rubber shock absorbing bushing, belongs 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 configuration of the present invention is simple, compact, reasonable, 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 present invention relates to a kind of automobile rubber shock absorbing bushing, belongs 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 is difficult adjusts, and in order to strengthen the comfort of automobile, is needed
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.
The content of the invention
It is an object of the present invention to overcome the above deficiencies, so as to provide a kind of automobile rubber shock absorbing bushing, carries significantly
The high structural strength of bushing, processing are simple and of low cost.
According to technical solution provided by the invention, a kind of automobile rubber shock absorbing bushing includes metal inner pipe, rubber bodies and modeling
Expect outer tube, metal inner pipe is located at plastic outer tube center, filled rubber body between metal inner pipe and plastic outer tube, and passes through rubber
Colloid links into an integrated entity metal inner pipe and plastic outer tube, it is characterized in that：Metal inner pipe center outer surface is equipped with the convex of circular ring shape
Structure is played, bulge-structure is 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 whole 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 present invention has the following advantages：
The configuration of the present invention is simple, compact, reasonable, plastic outer tube port, which is shunk, effectively to prevent rubber bodies from being taken off with plastic outer tube
Fall；Metal inner pipe middle projective structure ensures that the rubber bodies after vulcanization do not come off with metal inner pipe；Outside two semicircle plastics
Pipe effectively reduces processing cost.
Brief description of the drawings
Fig. 1 is the half-sectional structure chart of the present invention.
Description of reference numerals：1- metal inner pipes, 2- rubber bodies, 3- plastic outer tubes, 4- bulge-structures, 5- closing-in structures.
Embodiment
The present invention will be further described with reference to the embodiment in attached drawing below：
As shown in Figure 1, the invention mainly comprises metal inner pipe 1, rubber bodies 2 and plastic outer tube 3, metal inner pipe 1 is located at outside plastics
3 center of pipe, filled rubber body 2 between metal inner pipe 1 and plastic outer tube 3, and by metal inner pipe 1 and moulded by rubber bodies 2
Material outer tube 3 links 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, raised
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 whole 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.
Operation principle of the present invention：The super-elastic having by rubber bodies is used as the impact-absorbing medium of rubber shock-absorbing bushing, will
The matched metal inner pipe of rubber bodies after vulcanization and plastic outer tube composition are used to alleviate rubber shock-absorbing bushing institute connection body
The vibration of component, reduces the noise produced in the operational process of automobile, improves the comfort of driver and passenger.
The present invention is capable of providing torsion and the damping of vertical direction, and for Bit andits control axially and radially, using compared with
Low rubber hardness can reach corresponding rigidity requirement, and torsion stiffness also can obtain effective control, improve product quality and
Damping effect.
