Abstract
The invention discloses a railway modular assembling underframe and a vehicle structure comprising the same. The railway modular assembling underframe comprises a middle beam module, at least two first cross beam modules, at least two sleeper beam modules and at least two side beam modules. The middle beam module is located in the middle of an underframe body, penetrates through the underframe body in the longitudinal direction of the underframe body, and is used for being connected with a coupler buffer device and a bogie. The first cross beam modules are positioned at the two ends of the underframe body correspondingly, are arranged in the transverse direction of the underframe body and are fixed to the middle beam module through fasteners. The sleeper beam modules are located at the positions near the two ends of the underframe body, are arranged in the transverse direction of the underframe body and fixed to the middle beam module through fasteners, and are used for being connectedwith the bogie. The side beam modules are positioned on the two sides of the middle beam module correspondingly and are used for connecting every two adjacent modules through fasteners.
Description
technical field [0001] The invention relates to an underframe for a railway freight flat car, in particular to a modularly assembled flat car underframe and a whole vehicle structure including the underframe. Background technique [0002] The inventor found that the existing railway flat car underframe adopts a welded integral structure, and the size of the underframe after the production of the underframe is fixed and cannot be disassembled and adjusted. For cargo containers of different sizes, when vehicles with fixed chassis are used for transportation, the transportation space of the chassis may be short and cannot be loaded, or the transportation space of the chassis may be rich and the transportation space may be wasted, which seriously affects the transportation of railway transportation. efficiency and throughput. [0003] For the exported railway flat car, since the underframe cannot be disassembled, long-distance sea transportation can only be transported by the w...
