Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, elaboration detailed is further done to the technical solution of the utility model.
Embodiment 1: as depicted in figs. 1 and 2, a kind of railway Rapid freight train buffer rubber gasket, comprise rubber pad body 1, the side of described rubber pad body 1 is provided with metal sheet 2, the side of described metal sheet 2 and the side of rubber pad body 1 sulfide, and the other side of metal sheet 2 contacts with steel spring (not shown); The other side of described rubber pad body 1 is provided with multiple groove 3, and the other side being provided with the rubber pad body 1 of multiple groove 3 contacts with truck journal box (not shown).Rubber pad body and metal sheet are all set to circle, after buffer rubber gasket installs, by contacting with the cooperation attachment face of axle box on reeded rubber pad body and bogie truck, make when rubber pad body bears compressive deformation, significantly reduce the loaded area of rubber pad body, increase the free surface of rubber pad body, add the deformation space of rubber pad body, thus significantly reduce the compression stiffness of rubber pad body, under the condition of buffer rubber gasket thinner thickness, achieve less compression stiffness, there is less vertical stiffness, both ensure that the service life of product, meet again the requirement of Rapid freight train dynamic performance, in addition, contacting with steel spring by setting up metal sheet, avoiding steel spring and rubber pad body directly to contact and making rubber bodies discontinuity and produce stress concentrate and cause the destruction of rubber face, further increasing the service life of product.
Described groove 3 is set to multiple circle shape groove 3, and multiple circle shape groove 3 is distributed on the other side of rubber pad body 1 successively along the radial direction of rubber pad body 1.In the present embodiment, be provided with two circle shape grooves 3 altogether, also can arrange more than three or three here.
Each circle shape groove 3 is sequential like groove 3, reduce further the loaded area of rubber pad body, increases the free surface of rubber pad body, add the deformation space of rubber pad body, thus reduce further the compression stiffness of rubber pad body.
In the present embodiment, described groove 3 is trapezoidal along the axial cross section shape of rubber pad body 1, trapezoidal upper base is positioned near metal sheet 2 side, trapezoidal bottom is positioned at away from metal sheet 2 side, here, groove 3 can also be set to other shapes such as rectangle or circular arc along the axial cross section shape of rubber pad body 1.
As shown in Figure 3, the periphery of rubber pad body 1 is set to arcwall face 4, like this, when rubber pad body bears compressive deformation, the degree that rubber pad body expands can be reduced outwardly, avoid phase mutual friction between rubber pad body that over expansion goes out with miscellaneous part, thus the problem reducing rubber pad body service life occurs.
As shown in Figure 2 and Figure 4, the center of railway Rapid freight train buffer rubber gasket has through hole, described through hole comprises the through hole 1 be positioned on rubber pad body 1 center and the through hole 26 be positioned on metal sheet 2 center, the inner peripheral surface of described through hole 1 is arcwall face, through hole 26 is clear opening, such setting also can make rubber body reduce internal circular surfaces degrees of expansion outwardly, avoid the phase mutual friction between miscellaneous part, postpone its service life, also it can be made to assemble up convenient and swift, improve the efficiency of assembling of buffer rubber gasket.
As shown in Figure 3 and Figure 4, during sulfuration, the side of described rubber pad body 1 extends parcel contact on the outer peripheral face of metal sheet 2 and on the inner peripheral surface of the through hole 26 of metal sheet.Rubber and metal sheet bond area can be increased like this, and prevent from occurring corrosion phenomenon in metal sheet outer circumference surface and inner peripheral surface use procedure.
Embodiment 2: as shown in Figure 5 and Figure 6, compared with embodiment 1, difference is: each circle shape groove 3 is interrupted shape groove 3, namely each circle shape groove 3 is divided into multiple point groove 31 circumferentially distributed, and adjacent interrupted shape groove 3 is dislocatedly distributed on the other side of rubber pad body 1.By above-mentioned setting, groove is uniformly distributed on rubber pad body, ensure that rubber pad intrinsic single uniform force, improve reliability and the service life of buffer rubber gasket.
To sum up, the utility model is contacted by the cooperation attachment face of axle box on the reeded rubber pad body of band and bogie truck, make when rubber pad body bears compressive deformation, significantly reduce the loaded area of rubber pad body, increase the free surface of rubber pad body, add the deformation space of rubber pad body, thus significantly reduce the compression stiffness of rubber pad body, under the condition of buffer rubber gasket thinner thickness, achieve less compression stiffness, there is less vertical stiffness, both ensure that the service life of product, meet again the requirement of Rapid freight train dynamic performance, in addition, contacting with steel spring by setting up metal sheet, avoiding steel spring and rubber pad body directly to contact and making rubber bodies discontinuity and produce stress concentrate and cause the destruction of rubber face, further increasing the service life of product.By arranging sequential like groove, reduce further the loaded area of rubber pad body, increasing the free surface of rubber pad body, add the deformation space of rubber pad body, thus reduce further the compression stiffness of rubber pad body.By arranging interrupted shape groove, groove being uniformly distributed on rubber pad body, ensure that rubber pad intrinsic single uniform force, improve reliability and the service life of buffer rubber gasket.
Above embodiment is only for illustration of the utility model, but not limitation ot it.The relevant technologies personnel of related fields, when not departing from spirit and scope of the present utility model, can also make a variety of changes or convert.Therefore, all equivalent technical schemes also should belong to protection domain of the present utility model.Protection domain of the present utility model should be limited by each claim.
