Some embodiments of the present disclosure provide a chassis component of a railway vehicle, and a railway vehicle. The chassis component includes two lower boundary beams provided at an interval and a sleeper beam provided between the two lower boundary beams. The sleeper beam includes: a web structure; a center pin, connected with a bogie of a railway vehicle; and a mounting frame, connected with the web structure, the center pin being provided on the mounting frame, the mounting frame including a plurality of vertical plates, and the plurality of vertical plates being provided at an interval along an outer wall surface of the center pin. The technical solution of the present disclosure can solve the problem in the related art of insufficient connecting strength of a center pin and a web structure of a sleeper beam.

Chassis component of railway vehicle, and railway vehicle

Some embodiments of the present disclosure provide a side wall component of a railway vehicle, and a railway vehicle. The side wall component of a railway vehicle includes: a side wall, including a side wall body; and a plurality of side wall upright columns, connected with the side wall body respectively, the plurality of side wall upright columns being provided along a length direction of the side wall body at an interval, wherein an auxiliary air duct of a railway vehicle is formed between at least two of the plurality of side wall upright columns and the side wall body in the length direction of the side wall body. According to some embodiments of the present disclosure, an auxiliary air duct of a railway vehicle is directly formed on a side wall, so that the railway vehicle is compact in structure.

Side wall component of railway vehicle, and railway vehicle

Provided are a vehicle end skeleton structure and a rail vehicle having the same. The vehicle end skeleton structure comprises: a roof structure, the roof structure being a closed frame structure; and an end energy absorption structure, the upper end of the end energy absorption structure being connected with the roof structure, and the lower end of the end energy absorption structure being connected with a chassis. The technical solution provided in the present invention can solve the problem in the conventional art in which the collision performance of a vehicle end skeleton structure cannot meet current demands.

Vehicle end skeleton structure and rail vehicle having same

The disclosure provides a chassis component of a railway vehicle, and a railway vehicle, the chassis including two lower boundary beams, the two lower boundary beams being provided at an interval; and a cross beam component, the cross beam component being provided between the two lower boundary beams, wherein there are a plurality of cross beam components, and the plurality of cross beam components are provided along a length direction of each of the lower boundary beams at an interval, wherein at least one cross beam component includes a first cross beam and a second cross beam provided below the first cross beam in a height direction of the each of the lower boundary beams, the first cross beam and the second cross beam form a mounting cavity, and a part of a floor of a railway vehicle penetrates into the mounting cavity.

A beam structure includes a lower cover plate, an upper cover plate and two side web plates jointed between the upper cover plate and the lower cover plate; wherein the two side web plates are arranged perpendicularly to the upper cover plate and the lower cover plate, respectively, to form a hollow box-shaped structure; rib plates protruding outwardly with a plurality of plug heads are welded within the box-shaped structure; the plug heads are respectively plugged in the upper cover plate, the two side web plates and the lower cover plate, and each plugging joint is fixed by laser-MAG hybrid welding from outside of the box-shaped structure. The method includes: assembling two side web plates, rib plates and a lower cover plate on an upper cover plate to form a box-shaped structure; and welding each of joints from outside of the box-shaped structure by laser-MAG hybrid welding.
