Train body chassis edge beam structure and train body with same

Abstract

The invention relates to the technical field of railway train manufacturing, and discloses a train body chassis edge beam structure and a train body with the same. The train body chassis edge beam structure comprises a train body chassis upper edge beam structure and a train body chassis lower edge beam structure, wherein the train body chassis upper edge beam structure comprises a train body inner side rib plate arranged on the upper plane of a train body floor and extending upwards, and the train body chassis lower edge beam structure comprises train body outer side main bearing vertical ribs which are arranged on the upper plane of the train body floor and extend downwards, and train body inner side main bearing vertical ribs opposite to the train body outer side main bearing vertical ribs; and the thickness of the train body outer side main bearing vertical ribs and the thickness of the train body inner side main bearing vertical ribs are equal and both larger than the thickness ofthe train body inner side rib plate. The train body chassis edge beam structure has the advantages of being high in structural strength, good in rigidity and capable of meeting requirements of trainlower equipment edge beam hanging and mounting of city region subway platform trains.

Description

technical field [0001] The invention relates to the technical field of railway vehicle manufacturing, in particular to a car body underframe side beam structure and a car body with the same. Background technique [0002] The weight of a single device installed on the side beam of the existing urban rail vehicle chassis is generally less than 2 tons. When it is applied to a 25kV (kilovolt) line, it is necessary to install a traction transformer weighing nearly 4 tons and a converter weighing more than 2 tons. , the original edge beam structure cannot withstand such a load. [0003] The EMUs used on 25kV lines generally only have passenger compartment doors at both ends (and outside the corbel). The transformer under the car is carried by the side beams and side walls of the chassis as a whole. The existing side beam structure can bear such loads. [0004] The undercarriage equipment of the intercity EMU has also reached the level of 4 tons, but the plan of hanging the underf...

AI Technical Summary

Problems solved by technology

[0007] The object of the present invention is to provide a car body underframe side beam structure and a car body with it, so as to at least solve the weak structural strength of the car body underframe side beam and the pillow inner door area in the prior art, which cannot meet the needs of the market. Technical issues related to the requirements for hanging and installing the side beams of the under-vehicle equipment of subway platform trains
