Description
Technical field
The invention belongs to railway transportation device and manufacture and design field, especially belong to bogies for railway vehicles knot
Structure design and manufacture, particularly to a kind of framework for quick railway goods train bogie.
Background technology
Rapid speed freight car bogie is due to braking ability and the needs of dynamic performance, and general employing entirety is welded
Connect formula framework, and carry out the design of different structure according to principle and structural models.Existing Rapid freight train
Steering structure shelf structure its there is more deficiency.
As central mounting device cushion cap is set directly on the upper cover plate of U-shaped depressed area of curb girder, by
The restriction of plane height to the top of rail on central mounting device, the setting height(from bottom) of suspension is typically only capable of reaching
About 100mm～120mm.And using amount of deflection big, the central mounting device that rigidity is little is not only advantageous to
The vibration of reduction system, is also beneficial to the raising of rapid speed freight car bogie critical velocity, realize above-mentioned
Target has different solutions at present, and existing framework can not meet this requirement；
And for example crossbeam uses round steel pipe directly to run through curb girder web, and uses circular weld with curb girder web
Welding, before welding, curb girder is the open architecture of web holes, and structural-load-carrying capacity is the strongest；Weld seam
Connect more weak, when by bigger torsional load, there is the risk ftractureed.
At present for the design synthesis technology of each subject of bogie frame, including material, structure,
The fields such as stress, bearing mode, cushion technique, being one incorporates more multi-field designing technique,
The most constantly exploring innovation with the needs adapting to more high technology development in industry.

Being truck side sill structural representation of the present invention in conjunction with Fig. 2 and Fig. 3, Fig. 2, Fig. 3 is the present invention
The schematic diagram of central mounting device cushion cap on truck side sill, in order to increase central mounting device peace further
Dress height, adapts to use the central mounting device of more large deflection and less rigidity, by central mounting cushion cap 3
Face is moved down in lower gripper shoe 10 by upper cover plate 4 plane of curb girder U-shaped recess, and central authorities are outstanding simultaneously
Hang cushion cap 3 and outside curb girder 1, increase bogie central mounting horizontal by moving to outside curb girder 1 centrage
Distance, bogie is shaken the head to retrain by car body to be increased, and is conducive to improving the critical velocity of bogie.This
Invention central mounting cushion cap 3 uses multilayer steel plates to combine and arranges cross reinforcing rib and is welded and fixed structure,
Particularly lower supporting plate 11 is structure as a whole with curb girder 1 bottom surface, has both reduced welding, structural strength higher,
In figure, lower supporting plate 11 is structure as a whole with curb girder 1 lower cover 5；The present invention is especially by upper backup pad 10
Running through curb girder 1 to be welded and fixed, increase bearing capacity and stability, in figure, upper backup pad 10 is an entirety
Panel runs through curb girder 1 and is welded and fixed, and forms the plane of central mounting cushion cap 3 less than curb girder 1 groove-bottom
Face, arranges longitudinal gusset 12 and horizontal gusset 13 to increase between upper backup pad 10, lower supporting plate 11
Carrying stress.
Being truck transom structural representation of the present invention in conjunction with Fig. 4 and Fig. 5, Fig. 4, Fig. 5 is the present invention
The curb girder provided and beam connecting structure cross-sectional schematic.The present invention uses round steel pipe as framework
Connecting cross beam 2, as shown in Figure 2 and Figure 5, curb girder 1 is spelled by upper cover plate 4, lower cover 5 and web 6
Weldering composition, perforate arrange sleeve 7 and run through in the middle part of web 6, curb girder 1 forms the " u "-shaped case closed
Formula structure.Crossbeam 2 uses the mode that round steel pipe runs through with two ends curb girder 1 sleeve 7, segmentation is welded to connect
Connecing, crossbeam 2 steel pipe through sleeve 7 and welds with it, forms an overall load knot with curb girder 1
Structure, uses this structure to be conducive to suitably reducing the diameter of horizontal stage casing round steel pipe, reduces weight, improve
Crossbeam 2 and the welding quality of curb girder 1 and reliability, disperse curb girder 1 with horizontal especially by sleeve 7
Beam 2 directly acts on, and makes stress evenly, increases bearing capacity further, improves safety and stablizes
Property.
