Description
Technical field
The utility model is related to railway goods train bogie technical field, and in particular to scooter 160km/h iron when a kind of
Road red ball bogie bolster.
Background technology
At present during design railway rapid speed freight car bogie bolster, to reach purpose that lightweight and fatigue reliability is high, shake
Rest the head on agent structure and typically use plate welding structure.In plate welding structure, the allowable stress of welded seam area is lower than mother metal, it is impossible to
Meet the requirement of design standard.In the prior art, when stress exceedes allowable stress near welded seam area, typically there are two kinds of processing
Mode, one is increase sheet material thickness of slab or structural member profile height, but this method can cause bolster weight to increase；Another is to adopt
With the higher sheet material of performance rate, but this method causes sheet material purchase cost and processing cost increase, welding difficulty increase.
As Chinese utility model patent (publication number CN202541558U, publication date 2012.11.21) discloses a kind of quick
The bolster of railway goods train bogie, bolster is convex configuration, using ball center plate, and bolt hole is provided with side bearing, and traction is drawn
Pole socket is arranged under bolster on the inside of gooseneck bracket, is welded with bolster web and lower cover using corner connection mode.The bolster is integrally used
Sheet material is welded so that the stress of commissure is larger, and its end is also rubber metal pad mounting seat without two.
The content of the invention
The purpose of this utility model there is provided a kind of is not increasing the situation of bolster weight aiming at the deficiency of above-mentioned technology
The intensity of lower increase bolster, improvement two are the railway red ball bogie bolster of rubber metal pad heat dispersion.
To achieve the above object, the railway red ball bogie bolster designed by the utility model, including on bolster
Cover plate, bolster lower cover, bolster web and a pair of side bearing boxes for being arranged on bolster upper cover plate both sides；
Also include being located at bolster web two ends a pair two are rubber metal pad mounting seat, and a pair two are the upper of rubber metal pad mounting seat
Surface is docked with the lower surface at bolster upper cover plate two ends, is for a pair two the mounting seat web end face and bolster abdomen of rubber metal pad mounting seat
Plate both ends of the surface are docked, and are for a pair two that the lower surface end face of rubber metal pad mounting seat is docked with bolster lower cover both ends of the surface；
The pair of two be that the leading section of rubber metal pad mounting seat is provided with that to extend vertically through the two of leading section be rubber metal pad mounting hole,
And be for a pair two that the rearward end of rubber metal pad mounting seat is distributed relative to bolster in skew symmetry；
On the bolster upper cover plate and to face two be that two are provided through at the position of rubber metal pad mounting hole is rubber metal pad
The spacing ring set spacing for convex navel is provided with the positioning hole of convex navel, the positioning hole；The pair of two be that rubber metal pad is installed
The rear end lower surface of seat is welded with the second drawing pull bar seat.
Further, the pair of two be that the rearward end of rubber metal pad mounting seat is highly less than leading section height, and institute
State arc transition between leading section and the rearward end.
Further, the bolster upper cover plate includes the matrix of one piece of front shroud, one piece of back shroud and one piece of downward indent
Cover plate, the matrix cover plate two ends are integral with the front shroud and the back shroud butt welding shape respectively；The matrix cover plate
Stiffener plate is welded between the side of lower surface two and the bolster web, the bottom surface of the matrix cover plate is welded with cartridge pad
Plate.
Further, the pair of two be the two of rubber metal pad mounting seat be rubber metal pad mounting hole upper surface be provided with it is described
The two of bolster upper cover plate lower surface welding are rubber metal pad backing plate, and described two be to be provided with rubber metal pad backing plate and the positioning hole phase
Correspondence and the backing plate through hole of connection.
Further, it is that rubber metal pad is installed that the second drawing pull bar seat is welded on described two by drawing pull bar seat bottom plate
On the lower surface in base rear end portion.
Further, the side bearing box encloses welding by two U-shaped plates and formed, and the side bearing cassette bottom portion passes through side bearing box pad
Plate weld is welded on the bolster upper cover plate, and between the transverse slat outer surface of each U-shaped plate and the bolster upper cover plate
There is side bearing box gusset.
Further, the two sides of the bolster web are welded with the second transverse hydraulic shock absorber mounting seat, two institutes
The second transverse hydraulic shock absorber mounting seat is stated to be distributed relative to the bolster web skew symmetry.
Further, the bolster lower cover two ends are welded with a pair second horizontal stopping seats.
Compared with prior art, the utility model has advantages below：
1st, two using forging are that rubber metal pad mounting seat replaces actual stress to exceed the welding structure of allowable stress, and improving should
The intensity at position.Because original welding portion is replaced via mother metal, its allowable stress also accordingly brings up to the level of mother metal,
Although the stress at this is not reduced, because the allowable stress at the position has been improved, therefore do not changing structure at this
Under the premise of, i.e., the intensity of bolster is improved in the case where not increasing weight, also not improving timber intensity grade；
2nd, two be rubber metal pad mounting seat rearward end highly be less than leading section height, i.e., used between leading section and rearward end
Variable cross-section is designed, and it is that rubber metal pad has more positions to expose to make two, is the radiating rate of rubber metal pad to improve two, so as to improve
Two be the heat dispersion of rubber metal pad；
3rd, using the recessed bolster in middle part, cartridge is advantageously reduced to rail level height, that is, reduces the center of gravity of vehicle.
