Technical field
The utility model relates to railway truck red ball bogie technique field, refers to particularly a kind of steering frame swing bolster of lorry transverse elasticity stop device.
Background technology
The mode that limits at present bolster transverse shifting in railway goods train bogie mainly contains two kinds, one is rigidity restriction, be common in three-piece bogie the bolster gear itself arranging on bolster, another kind is the transverse elasticity backstop of setting between bolster and framework composition on traditional passenger car bogie.Tradition passenger car bogie and part have the transverse elasticity backstop of the roller bearing adapter stabilizer bar employing of framework, bolster, mainly contain two kinds of mounting meanss, a kind of is that transverse elasticity backstop is directly installed in the mounting hole arranging on framework or bolster, and another kind is by bolt, transverse elasticity backstop to be installed on bolster.But these two kinds of structures bolster and framework transverse distance less in just more difficult realization, and install and decompose comparatively trouble.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned defect, provide a kind of simple in structure, easy for installation, dismounting easily, the steering frame swing bolster of lorry transverse elasticity stop device of reliable operation.
For achieving the above object, the steering frame swing bolster of lorry transverse elasticity stop device that the utility model is designed, is arranged between the framework and bolster of bogie truck.It comprises the horizontal backstop mount pad being weldingly fixed on framework or bolster and the transverse elasticity stop block detachably coordinating with it.Described transverse elasticity stop block has the surperficial top board, intermediate rubber layer and the bottom disc that are combined into one, edge one side of described bottom disc is provided with circular arc flange, the edge opposite side of described bottom disc is provided with fan-shaped flange, and the external diameters such as described circular arc flange and fan-shaped flange concentric are arranged.Described horizontal backstop mount pad has the surperficial pressure ring and the bottom seat ring that are combined into one, and the inner ring diameter of described surperficial pressure ring is less than the inner ring diameter of bottom seat ring, thereby forms the circular cavity that holds bottom disc; Inner ring one side of described surperficial pressure ring is provided with arc gap, the inner ring opposite side of described surperficial pressure ring is provided with sector notch, the external diameters such as described arc gap and sector notch concentric are arranged, and corresponding with the shape of circular arc flange and fan-shaped flange respectively, thereby bottom disc can be pushed in circular cavity smoothly when mounted, and connect and fix therein by rotating the arbitrarily angled bottom disc that makes.
Further, between described circular arc flange and fan-shaped flange, be 180 ° of layouts; Correspondingly, between described arc gap and sector notch, be also 180 ° of layouts.Like this, transverse elasticity stop block rotates 180 ° with horizontal backstop mount pad and sets, and can make to install fixed.
Further, described circular arc flange is 1: 4～6 with the arc length ratio of fan-shaped flange.Like this, the area of contact of transverse elasticity stop block in horizontal backstop mount pad is larger, can guarantee working stability.
Further, described surperficial top board and bottom disc are steel top board and steel disk, overall sulfidization molding between they and intermediate rubber layer.Like this, adopt the unitized construction of steel and rubber, different rigidity can be set as required, meet the needs of backstop.
Further, described surperficial pressure ring and bottom seat ring adopt member assembly welding or mono-block cast to process.Like this, simple in structure, be convenient to processing.
The utility model has the advantage of: transverse elasticity backstop mount pad is arranged on steering frame swing bolster of lorry or framework as required, transverse elasticity backstop base is put into hole corresponding to transverse elasticity backstop mount pad, directly Rotate 180 degree can not come off transverse elasticity backstop in utilization process; This mounting structure is simple, dependable performance,, installs simply meanwhile, saves installing space feature easy to maintenance.
