Abstract
The invention discloses a truck under-frame connected beam and a carriage. The connected beam comprises a connected beam body with a flat straight plate structure; and two sides of the connected beam body are respectively provided with a connector for transition-connecting the connected beam body to lateral walls of the carriage so that the lower part of the section of the carriage becomes a variable cross section gradually narrowed from the connection positions between the lateral walls and the connectors. The carriage comprises the connected beam. In the embodiment of the invention, the frame connected beam can be in transition connection with the lateral walls of the carriage to ensure that the whole carriage is wide at the upper part and has a gradually narrowed variable cross section at the lower part, thereby ensuring that the lateral walls of the whole carriage approach to a railway clearance as much as possible and the volume of the whole carriage is maximized, and effectively improving the goods loading capacity of railway wagons.
Description
Technical field
The embodiment of the invention relates to the railway truck technical field, relates in particular to a kind of truck under-frame connected beam and compartment.
Background technology
Goods train carriage is the space that the side wall by underframe, front and back body of wall and the left and right sides surrounds, and is used for lade.Important reference when the volume in compartment is the compartment design, the volume in compartment will mate with lade, therefore, in the design in compartment, to make the basal area maximization in compartment as far as possible, with the length that reduces vehicle, the deadweight that reduces vehicle, and then in certain train marshalling list length, improve the freight-transport capacity of lorry, improve the economic benefits of transportation efficiency.
Fig. 1 is the section structure scheme drawing of existing flat goods train carriage.As shown in Figure 1, in the existing flat goods train carriage, tie-beam 11 on the underframe is a plate armature, side wall 12 tie-beams 11 direct and plate armature are fixed together, hopper car for fixed high loading hatch, the restriction of high gauge can't be by increasing the volume that height of car improves the compartment for railway, and the structure of tie-beam 11 just becomes the critical component that improves the vehicle volume.But, though because the wider width between the gauge A of top in the railway clearance of both sides, and width is narrower between the gauge B of bottom, and the tie-beam structure of existing plate armature fails to make full use of railway clearance, make that the volume in whole compartment is less, reduced the loading amount of lorry.
Fig. 2 is the structural representation of existing variable section goods train carriage.As shown in Figure 2, in the existing variable section goods train carriage, tie-beam 14 on the underframe still adopts plate armature, simultaneously, for improving the volume in compartment, side wall 13 adopts circular arc wrapper sheet sidewall structure, utilize its arc to protrude to top gauge A direction, for compartment shown in Figure 1, the effective cross sectional area of variable section goods train carriage increases, thereby has increased the volume in compartment.But; the side wall in the compartment of this structure is owing to adopt circular arc; only limit to load and the transportation loose goods; other goods is owing to the shape restriction and do not have flowing power; can not freely be filled in the space that the arc side wall constitutes between the summit about in the of 13, thereby make this segment space fail effectively to utilize.
The contriver finds in realizing process of the present invention; existing under-frame connected beam adopts in the goods train carriage of plate armature; the volume in whole compartment is less; though perhaps the volume in compartment increases to a certain extent; but; only can load loose goods, limit the compartment and carried cargo, make that the lorry ability that carries cargo is relatively poor.
Summary of the invention
