At present, the version of the compound journal box spring of rubber-metal mostly is taper shape and V-arrangement, and there are the bigger characteristics of vertical amount of deflection in the journal box spring of these two kinds of forms, therefore the also incompatible positioning end that is used for the rocker style configuration bogie truck, and the journal box spring of these two kinds of forms is because of the structural strength requirement, metal piece need adopt steelwork, and product design is bigger.Therefore necessary this is improved.
Summary of the invention
The objective of the invention is at existing one is the deficiency of the compound axle box spring damping of rubber-metal product, provide a kind of less vertical amount of deflection that has, the compound journal box spring of rubber-metal of bigger vertical stiffness (big load bottom offset little) and bigger vertical, horizontal rigidity.
According to the technology implementation scheme that purpose of the present invention proposed be: the compound journal box spring of a kind of rubber-metal comprises mandrel; Rubber bodies; Base, rubber bodies are in the same place with mandrel and base sulfuration adhesion respectively up and down.It is characterized in that: the compound journal box spring of described rubber-metal is the sphere journal box spring, and rubber bodies is the sphere compound shape body that sphere combines with column.Wherein, the rubber bodies bottom is the spherical shape body, and the rubber bodies side is a column, and spherical shape body and column smoothly join.Bottom in rubber bodies spherical shape body portion has a circumferential notch, but breach remains with the spherical rubber layer that one deck and mandrel bottom matches; Have two semicircle breach in rubber bodies side column part also symmetry.The compound shape body that the sphere that mandrel also is with the rubber bodies inner face matches combines with column, the mandrel bottom is the spherical shape body, and the mandrel side is a column, and the shape body portion of mandrel and column part are smoothly joined.Top at mandrel has blind hole.The compound shape body that the sphere that the endoporus of base is with the rubber bodies outside face matches combines with column, the endoporus bottom of base is the spherical shape body, the endoporus side of base is a column, has the hole in the bottom of base, and the spherical shape body breach of hole and rubber bodies bottom is connected as a single entity.Mandrel and base adopt the light aluminum alloy material, and elastic damping is born by the sphere rubber bodies, and rubber bodies and light aluminum alloy framing member are sulfided into one, thereby constitute a complete journal box spring.
The present invention can limit from vertical amount of deflection aspect to some extent owing to be to adopt the sphere rubber bodies to play the elastic damping effect, reduces vertical amount of deflection, and can increase to some extent aspect the vertical, horizontal rigidity, forms the sphere journal box spring.The sphere journal box spring is because it has bigger vertical stiffness and vertical, horizontal rigidity, and sphere generation all directions are reversed characteristics freely, played the effect of locating point preferably, and possesses certain flexibility again, therefore, can guarantee the easy motion of axle box in vehicle operating better, thereby realize the safety and comfort of vehicle operating.Therefore, the present invention can adapt to the positioning end of rocker style configuration bogie truck better.Simultaneously, because framing member adopts light aluminum alloy to make, the weight of product greatly reduces than steel spring, the special guideway vehicle weight-saving developing direction that adapts to, rubber is different that firm sulfuration adhesion and rubber lost efficacy and metal lost efficacy with Al-alloy parts in addition, and product in use reliability is high and non-maintaining.
