Abstract
A rail transit-used rubber joint comprises a metal outer sleeve, a spacer sleeve, an inner sleeve and two layers of elastic rubber body, wherein the spacer sleeve is positioned between the two layers of elastic rubber body; the outer layer of elastic rubber body and the outer sleeve and the spacer sleeve are integrally vulcanized; and the inner layer of elastic rubber body and the inner sleeve and the spacer sleeve are integrally vulcanized. The rubber joint is characterized in that the inner layer of elastic rubber body is longer than the outer layer of elastic rubber body; the stress areas of the two layers of elastic rubber body are guaranteed to be roughly equal, that is the products of the equivalent radii R from the rubber layers to the centre line and the equivalent length L of the rubber layers are basically equal; each layer of rubber is radially equally divided into a plurality of parts and all the parts basically meet the requirement that the products of R and L are equal; and the outer layer of elastic rubber body is thicker than the inner layer of elastic rubber body so as to ensure that the stresses of the two layers of elastic rubber body are basically equal and the fatigue lives of all layers of rubber of the product are the same. In addition, small round corners are chamfered at the joint of the first layer of rubber and the spacer sleeve and at the joint of the second layer of rubber and the outer sleeve to reduce stress concentration.
Description
Technical field
The utility model relates to a kind of block construction of rolling stock, be a kind of track traffic rubber arthrosis specifically, this kind track traffic mainly is suitable for the bogie truck of various kinds of vehicles vehicle with in the rubber elastic element with rubber arthrosis, also can expand to vibration damping, elastic joint part positions such as construction machinery and equipment.
Background technology
Rubber arthrosis class elastic element is the compound damping element of using always of a kind of rubber-metal, can be widely used in various vibration dampings, elastic joint part position, plays the effect of vibration and noise reducing, especially uses very general in the bogie truck of rolling stock.In order to satisfy the dynamic performance requirement of rolling stock, the performance requriements that the requirement of rubber arthrosis series products has every rigidity.In order to satisfy the performance of rubber arthrosis, when the rubber arthrosis radial rigidity requires very greatly, and axial stiffness requires relatively hour, requires rubber arthrosis to have rubber layer more than 2 layers usually.
In practice process in the past, the rubber arthrosis with two-layer rubber is the rubber layer equal in length often, and thickness equates.Because internal layer rubber loaded area is littler than outer, suffered stress is corresponding also bigger than skin, causes in the product use, and internal layer rubber tends to destroy in advance, occurs coming unstuck, defective such as crackle, causes product rejection, can not satisfy the product life requirement.Operating experience has for many years also confirmed this point, and as above the torsion bar joint shaft of No. 9 lines of Haiti iron is exactly because internal layer rubber stress is excessive, takes the lead in destroying and influences vehicle operating safety.These problems are anxious to be solved.
Summary of the invention
The purpose of this utility model, in order to overcome the deficiency of existing rubber arthrosis, the stress amplitude ratio that proposes a kind of each rubber layer is more even exactly, and rigidity stability is better, and the vulcanization of rubber is more even, has the rubber arthrosis of equal fatigue life.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of track traffic rubber arthrosis, comprise metal-coating, spacer, interior cover and two-layer elastic rubbery body, wherein spacer is between the two-layer rubber, and outer elastic rubbery body and overcoat and spacer; Internal layer elastic rubbery body and interior cover and spacer are that integral body sulfides.Its characteristics are: the internal layer rubber layer is longer than outer, the area of thrust surface of guaranteeing two-layer rubber are equal substantially, promptly all rubber layers are to long-pending the equating substantially of equivalent redius R with the rubber layer equivalent length L of line of centers, each layer rubber radially is divided equally into some five equilibriums, and each five equilibrium all satisfies the requirement that RxL equates substantially.And the variable thickness sample of double-ply rubber layer, outer layer rubber layer are than internal layer rubber bed thickness, and impartial substantially to guarantee the suffered stress of two-layer rubber, each layer of product rubber has equal fatigue life.
The utility model by adjusting each layer rubber layer area of thrust surface and the thickness of rubber layer, impartial substantially to guarantee the suffered stress of two-layer rubber, make the suffered stress basically identical of rubber layer of each layer, each layer of product rubber has equal fatigue life.Because the product distribution of stress is more even, the longer service life of product.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, metal-coating; 2, spacer; 3, interior cover; 4, outer elastic rubbery body; 5, internal layer elastic rubbery body; 6, little fillet.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, a kind of track traffic rubber arthrosis comprises metal-coating, spacer, internal layer elastic rubbery body and outer elastic rubbery body, and wherein spacer is between internal layer elastic rubbery body and the two-layer rubber of outer elastic rubbery body; And outer elastic rubbery body and overcoat and spacer, and internal layer elastic rubbery body and interior cover and spacer are that integral body sulfides.Its characteristics are: the internal layer elastic rubbery body is longer than outer elastic rubbery body, the area of thrust surface of guaranteeing two-layer rubber are equal substantially, promptly all rubber layers are to long-pending the equating substantially of equivalent redius R with the rubber layer equivalent length L of line of centers, each layer rubber radially is divided equally into some five equilibriums, and each five equilibrium all satisfies the requirement that R * L equates substantially.And the variable thickness sample of internal layer rubber layer and double-ply rubber layer, outer layer rubber layer are than internal layer rubber bed thickness, and impartial substantially to guarantee the suffered stress of two-layer rubber, each layer of product rubber has equal fatigue life.
In addition, at ground floor rubber and spacer junction and second layer rubber and the angle of falling the roundlet, overcoat junction 6, to reduce stress concentration.
Claims (3)
1. track traffic rubber arthrosis, comprise metal-coating, spacer, interior cover and two-layer elastic rubbery body, wherein spacer is between the two-layer rubber, and outer elastic rubbery body and overcoat and spacer, internal layer elastic rubbery body and interior cover and spacer are that integral body sulfides; It is characterized in that: the internal layer rubber layer is longer than outer, guarantees that the area of thrust surface of two-layer rubber are equal substantially, and promptly all rubber layers are to long-pending the equating substantially of equivalent redius R with the rubber layer equivalent length L of line of centers.
2. track traffic rubber arthrosis as claimed in claim 1 is characterized in that: the variable thickness sample of double-ply rubber layer, outer layer rubber layer are than internal layer rubber bed thickness, and be impartial substantially to guarantee the suffered stress of two-layer rubber.
