Embodiment Construction

[0044] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. For the convenience of description, if the words "up", "down", "left" and "right" appear in the following, it only means that the directions of up, down, left and right are consistent with the drawings themselves, and do not limit the structure.

[0045] Such as Figure 1-Figure 2 As shown, the rail vehicle underframe structure of this embodiment is mainly composed of underframe side beams 1 , end structures 2 , short floors 3 , long floor assemblies 4 and transition ribs 5 . The end structure 2 is connected with the underframe side beam 1 through the corbel 22 and the cross beam 25 to form an integral frame load-bearing structure, and then the short floor 3 and the long floor assembly 4 are put i...

Abstract

The invention discloses a railway vehicle and a vehicle body chassis structure thereof. The chassis structure comprises chassis edge beams, end structures, short floors, long floor assemblies and transition rib plates. The end structures and the chassis edge beams are connected to form an integral frame bearing structure, and the short floors and the long floors are assembled in the integral frame bearing structure to form an chassis structure. Each end structure is mainly composed of a hinged traction device installation base, a sleeper beam, a sealing plate, a traction beam, a cross beam and a cover plate. The hinged traction device mounting seat is connected with chassis edge beams through sleeper beams in the transverse direction, and is assembled and connected with long floors through a traction beam, a cover plate and a cross beam in sequence in the longitudinal direction; the two ends of the long floor assembly are connected with the corresponding underframe boundary beams respectively. According to the chassis structure, the problems that a power hinged type bogie interferes with a vehicle body, and the bearing requirement is higher are solved.

Description

technical field [0001] The invention relates to a rail vehicle and its car body underframe structure, which belongs to the technical field of rail transit vehicle body structures, and in particular to a high-strength rail vehicle and its car body underframe structure applicable to the installation of articulated bogies. Background technique [0002] Two adjacent car bodies of articulated light rail vehicles or articulated EMUs are connected through a common articulated bogie, which reduces the number of train bogies and intermediate couplers, reduces vehicle manufacturing costs and subsequent maintenance costs, and has light weight, Small vibration, low noise, good curve passing ability and other advantages are favored by foreign users, especially European users. [0003] Generally, the two head cars of the train are equipped with power bogies, and the articulated bogies without power are arranged between the cars. There are two main schemes for connecting the articulated b...
