Abstract
The utility model discloses a railway freight car underframe. Connecting portions of side beams and sleeper beams of existing railway freight car underframes are not matched in rigidity portion, that is, the rigidity of the connecting positions of web plates of sleeper beams and side beams is reduced suddenly, and when the longitudinal force is transferred to side beams through sleeper beams, the deformation of side beams at connecting positions large, so that the stress at connecting positions of side beams and sleeper beams is generally high and even exceeds the allowable stress of materials used by side beams, and low-rigidity parts connected with drawing beams are damaged. The railway freight car underframe is composed of a drawing beam (1), wherein the drawing beam is connected with a sleeper beam (2), and the sleeper beam is connected with a side beam (3).
Description
Technical field:
The utility model relates to a kind of rail wagon base frame.
Background technology:
There are the unmatched problem of rigidity portion in the curb girder of present rail wagon base frame and the connecting portion of sleeper beam, the web and the curb girder junction rigidity that are sleeper beam diminish suddenly, when longitudinal force is delivered to curb girder by sleeper beam, curb girder is larger in the distortion of junction, cause the stress of curb girder and sleeper beam junction generally larger, even surpass the permissible stress of curb girder material used, cause the little rigidity parts failure that is connected with draw beam.
Summary of the invention:
The purpose of this utility model is to provide a kind of rail wagon base frame, has suppressed draw beam around the moment that sleeper beam rotates, and has avoided being welded on the destruction of the little rigidity parts on draw beam.
Above-mentioned purpose realizes by following technical scheme:
A kind of rail wagon base frame, its composition comprises: draw beam, described draw beam is connected with sleeper beam, and described sleeper beam is connected with curb girder.
Described rail wagon base frame, described sleeper beam comprises web, and described web is fixedly mounted between upper cover plate and base plate, and described base plate has extension board, has through hole on described web.
Described rail wagon base frame, described extension board is positioned at the junction of described sleeper beam and described curb girder, and described extension board is towards the middle part of described curb girder.
Beneficial effect:
The rigidity that the extension board that the utility model has by the sleeper beam base plate makes curb girder and sleeper beam base plate handing-over position is changed into transition gradually by the sudden change at body bolster diaphragm place, the transmission of longitudinal force also becomes oblique transmission from base plate by original right angle transmission, thereby has reduced the stress at curb girder and sleeper beam handing-over position.And after one side of base plate extended by extension board, the whole torsion stiffness of sleeper beam significantly improved, effectively suppressed the moment that draw beam rotates around sleeper beam, avoided being welded on the destruction of the little rigidity parts on draw beam, simple in structure, be convenient to make and safeguard.
Description of drawings:
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is structural representations of sleeper beam in accompanying drawing 1.
The specific embodiment:
Embodiment 1:
A kind of rail wagon base frame, its composition comprises: draw beam 1, described draw beam is connected with sleeper beam 2, and described sleeper beam is connected with curb girder 3.
Embodiment 2:
Above-mentioned rail wagon base frame, described sleeper beam comprises web 4, and described web is fixedly mounted between upper cover plate 5 and base plate 6, and described base plate has extension board 7, has through hole 8 on described web.
Embodiment 3:
Above-mentioned rail wagon base frame, described extension board is positioned at the junction of described sleeper beam and described curb girder, and described extension board is towards the middle part of described curb girder.
Claims (3)
1. rail wagon base frame, its composition comprises: draw beam is characterized in that: described draw beam is connected with sleeper beam, and described sleeper beam is connected with curb girder.
2. rail wagon base frame according to claim 1, it is characterized in that: described sleeper beam comprises web, and described web is fixedly mounted between upper cover plate and base plate, and described base plate has extension board, has through hole on described web.
3. rail wagon base frame according to claim 1 and 2, it is characterized in that: described extension board is positioned at the junction of described sleeper beam and described curb girder, and described extension board is towards the middle part of described curb girder.
