Suspended monorail train and its body structure

Abstract

The invention discloses a vehicle body structure of a suspension type monorail train. The vehicle body structure comprises two head cover edge beams extending in the length direction of a vehicle bodyand being in parallel and two underframe edge beams, and further comprises a coupling gear beam and a mounting structure which are used for being in bolt connection with coupling gears; the mountingstructure is fixedly connected to the front ends of the two head cover edge beams; the coupling gear beam is fixedly connected to the rear ends of the two head cover edge beams; the vehicle body structure further comprises vehicle falling beams and bogies; a horizontal corbelling is arranged in the inner side of each head cover edge beam; the upper surfaces of the two ends of the vehicle falling beams butt against and are in bolt connection with the lower surfaces of the corbellings of the two head cover edge beams; and the upper surfaces of the middle parts of the vehicle falling beams are connected to the bogies. The structural safety is improved; and the vehicle body structure has the advantages that the requirements for assembly accuracy are low; field manufacturing is convenient; disassembly is easy, later-period maintenance is convenient and the like. A force transferring path of the vehicle body structure is reasonable; and a whole structure has excellent strength and rigidity performance. The invention further provides the suspension type monorail train comprising the vehicle body structure.

Description

technical field [0001] The invention relates to the field of rail trains, in particular to a car body structure of a suspended monorail train. In addition, the present invention also relates to a suspended monorail train comprising the above car body structure. Background technique [0002] In order to connect the running parts of the upper part of the suspension monorail train, a drop beam structure is usually set on the top of the vehicle body structure to realize the suspension operation of the vehicle. In the prior art, the connection between the drop-off beam and the vehicle body is generally welded or riveted. [0003] However, the use of welded structures has problems such as inability to disassemble for later maintenance, weld fatigue, and difficulty in welding when dissimilar metals are used. There are also many problems in the riveted structure. The landing beam is usually installed on the inner side of the two roof side beams. Due to manufacturing errors, there ...

AI Technical Summary

Problems solved by technology

[0003] However, the use of welded structures has problems such as inability to disassemble for later maintenance, weld fatigue, and difficulty in welding when using dissimilar metals.

There are also many problems in the riveted structure. The landing beam is usually installed on the inner side of the two roof side beams. Due to manufacturing errors, there will be a certain deviation and unevenness in the inner width of the two roof side beams compared with the theoretical value. These dimensional deviations will Seriously affect riveting

In engineering, adjustment pads of different thicknesses are usually used for adjustment, but the effect is not ideal and time-consuming

The riveted structure also has the problem of difficulty in later maintenance and disassembly

The drop-off beam requires a connecting plate on the inner side of the side beam of the roof cover for riveting, and the connection between the connecting plate and the side beam of the roof cover is usually welded, and there is also the problem of weld fatigue in this area

[0004] At the same time, the current coupler installation structure of the suspended car body usually welds a certain number of support structures for local reinforcement on the rear side of the installation surface. improvement

In addition, due to the limited space at the end of the car body structure of the current suspended monorail train, there is not enough length to design the transition structure on the longitudinal force transmission path, and the stress concentration phenomenon is more obvious
