Utility model content
The purpose of this utility model is solve above-mentioned technical problem and provide a kind of rubber bushing, can use a set of work
Dress tests the rubber bushing rigidity of different contour structures, lowers development cost, shortens and changes the frock time.
To achieve the above object, the utility model adopts the following technical scheme that：
A kind of rubber bushing, including metal inner cylinder, metal outer cylinder and be placed between the metal inner cylinder, metal outer cylinder
Rubber layer, the metal inner cylinder, metal outer cylinder are combined to be formed and are integrated with the rubber layer, the middle part tool of the metal inner cylinder
The ring part of the rubber bushing radial rigidity can be changed by having, and the length of the metal inner cylinder is more than the length of the metal outer cylinder.
The ring part is the protuberance of annular, and the outside portion of the both sides of the protuberance is with the center pair of the protuberance
Claim arrangement, the protuberance is connected with the outside portion by arcwall face phase transition, and the diameter of described outside portion is identical, described
Protuberance diameter be more than outside portion diameter.
The ring part is the recess of annular, and the outside portion of the both sides of the recess is with the Central Symmetry cloth of the recess
Put, the recess is connected with outside portion by arcwall face phase transition, and the diameter of described outside portion is identical, the diameter of the recess
Less than the diameter of outside portion.
The utility model can be realized in the case of the size of limitation product inside and outside, by change the structure of metal inner cylinder come
Meet the requirement for improving or reducing rigidity, there is important production practices and realistic meaning.
Brief description of the drawings
Fig. 1 is the structural representation for the rubber bushing that the utility model embodiment provides；
Fig. 2 is that the rubber bushing that the utility model embodiment provides cuts open schematic diagram along line A-A.
Embodiment
Below, substantive distinguishing features of the present utility model and advantage are further described with reference to example, but this practicality is new
Type is not limited to listed embodiment.
Referring to shown in Fig. 1-2, a kind of rubber bushing, including metal inner cylinder 1, metal outer cylinder 2 and be placed in the metal
Rubber layer 3 between cylinder, metal outer cylinder, the metal inner cylinder are more than the metal except the thickness in the enhanced portion or decrease portion
The thickness of outer barrel, the metal inner cylinder, metal outer cylinder are combined to be formed and are integrated with the rubber layer, in the metal inner cylinder
Portion has the ring part that can change the rubber bushing radial rigidity, other parts of the metal inner cylinder in addition to the ring part
Thickness is more than the thickness of the metal outer cylinder, and the length of the metal inner cylinder is more than the length of the metal outer cylinder.
The ring part can be for annular protuberance 21, the outside portion 22 of the both sides of the protuberance 21 is with described convex
Go out being centrosymmetrically arranged for portion, as shown in Fig. 2 the protuberance 21 is connected with the outside portion 22 by arcwall face phase transition,
The diameter of described outside portion 22 is identical, and the diameter of protuberance 21 is more than the diameter of outside portion.Pass through such protuberance 21
Design, the radial rigidity of bushing can be increased.
Opposite, the ring part can (can be understood as the protuberance 21 inwardly to invert for the recess of annular
And recessed formation), outside portion being centrosymmetrically arranged with the recess of the both sides of the recess, the recess leads to outside portion
Cross arcwall face phase transition to connect, the diameter of described outside portion is identical, and the diameter of the recess is less than the diameter of outside portion.Pass through
The design of such recess, it is possible to reduce the radial rigidity of bushing.
The ring part be with metal inner cylinder integral production, on the barrel of the substantial metal inner cylinder by thickening or
It is thinning and formation.
Preferably, the length (including connection 22 excessive arcwall face of outside portion) of the protuberance 21 is the metal outer cylinder
The 2/3 of length, it is the 1/2 of the metal inner cylinder, the thickness of the metal outer cylinder is the outside portion (main body of the metal inner cylinder
Portion) thickness 1/2, the consistency of thickness of the metal outer cylinder.
The protuberance 21 be preferably above the outside portion 22 height be the outside portion 22 thickness 1/
2, the thickness of the rubber layer 3 is 2-2.5 times of the thickness of the metal inner cylinder (in addition to the corresponding ring part).
Of course, can be above-mentioned according to this for the recess as ring part-annular of the reverse design of protuberance 21
Specification on protuberance 21 accordingly carries out reverse recessed design.
It should be noted that during this is new, metal inner cylinder 2 is optimized into design, middle part protrusion, lining can be increased
The radial rigidity of set.By the row optimization design of metal inner cylinder 2, middle part depression, it is possible to reduce the radial rigidity of bushing.
Wherein, the length of the metal inner cylinder 1 is more than the length of the metal outer cylinder 2, and the rubber layer 3 is formed in end
Curved portions, realize in metal inner cylinder is wrapped in, and connection is combined with the inwall of the metal outer cylinder.
The metal inner cylinder 1, metal outer cylinder 2 can be made with steel or iron, or alloy material.
Wherein, the metal inner cylinder, metal outer cylinder and the rubber layer can be by vulcanizer by injecting rubber
Collagen material fuses and is combined and is formed as integral production and is formed.
A certain vehicle needs to improve the axial static rigidity of rubber bushing, it is desirable to is improved than base case (3500kN/mm)
200% (7000kN/mm).Simple increase sizing material hardness can not meet to require.Must be by changing the structure of metal inner cylinder
To improve overall rigidity value.
| Name of product | Pilot project | Current state | Effect | This novel product state | Effect |
| Bushing | Radial rigidity | Sizing material changes | It can not meet | Metal inner tube structure changes | It can meet |
Using the utility model product axial rigidity can be made to improve more than 200%.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
