Abstract
The utility model discloses a kind of truck bolster adapting to height of railway freight-car coupler and reduce, belong to railway goods train bogie technical field.Comprise with the symmetrically arranged bolster body of centre hole, four bearing ribs are provided with in described bolster body, described four bearing ribs composition interlayer casing also extends to two ends, the upper surface, middle part of described interlayer casing is the plane domain arranging centre hole, and the height of upper surface, described middle part is lower than the height of plane on the two ends of interlayer casing; Described two ends plane are respectively equipped with symmetrical side bearing box, and the height of described side bearing box inner bottom surface is lower than the height of plane on two ends.Middle part of the present utility model upper surface height and side bearing box high level of synchronization reduce, bolster upper end is concave structure, adopts this structure bolster body stressed effect good, has adapted to the requirement that height of railway freight-car coupler reduces, this bolster facilitates production and processing and maintenance, can improve conforming product rate; Be particularly useful for the international railway lorry that gauge is 1000mm.
Description
Technical field
The utility model relates to railway goods train bogie technical field.
Background technology
Goods train carriage requires to design according to the railway transportation in different countries, area, and the design of roller bearing adapter stabilizer bar must meet the operating needs of goods train carriage.Gauge is the railway transportation conditional request hitch height reduction of 1000mm, so just causes the design of the truck bolster of boxcar must adapt to the requirement of hitch height reduction.Compartment is arranged on bogie truck, truck bolster is provided with the elastic side bearing block in carrying compartment, elastic side bearing block is positioned at the side bearing box of truck bolster, relative height on cartridge on side bearing box bottom surface and bolster body centre hole between plane is a constant constant, its objective is the completion requirement in conveniently compartment.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of adapt to height of railway freight-car coupler reduce
Truck bolster, upper surface, middle part height and the side bearing box high level of synchronization with bolster body reduce, and make its convenient feature of assembling with the railway goods train of hitch height reduction.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of truck bolster adapting to height of railway freight-car coupler and reduce, comprise with the symmetrically arranged bolster body of centre hole, described bolster body is provided with four bearing ribs, described four bearing ribs composition interlayer casing also extends to two ends, it is characterized in that: the upper surface, middle part of described interlayer casing is the plane domain arranging centre hole, the height of upper surface, described middle part is lower than the height of plane on the two ends of interlayer casing; Plane is respectively equipped with symmetry at described two ends
Side bearing box, the height of described side bearing box inner bottom surface is lower than the height of plane on two ends.
To the further improvement that the utility model does be: the belly lower end of described interlayer casing protrudes formation lower arcuate surface downwards, the T slot of a pair symmetry is respectively equipped with at the both ends of the long axis direction of interlayer casing, the outer field bearing rib of interlayer casing is respectively equipped with symmetrical ear and bearing, described ear and bearing are equipped with bolt connecting hole.The elastic side bearing block contacted with bottom surface, compartment is provided with in described side bearing box.
The beneficial effect adopting technique scheme to produce is: middle part of the present utility model upper surface height and side bearing box high level of synchronization reduce, bolster upper end is concave structure, and plane is the planar structure of band one centre hole, eight bolt connecting holes on middle part, avoid stressed concentrated phenomenon, adopt this structure bolster body stressed effect good, adapted to the requirement that height of railway freight-car coupler reduces, this bolster facilitates production and processing and maintenance, can improve conforming product rate; Be particularly useful for the international railway lorry that gauge is 1000mm.
