Problems solved by technology

For this reason, the present invention proposes a side wall of a rail vehicle, which solves the problem that when the side wall column is welded to the side beam of the chassis, the gap between the side wall column and the side beam of the chassis is inconsistent, and the gap at some positions is relatively large due to the inability to completely match the deflection. Technical problems that cannot be welded

Abstract

The invention relates to the field of rail vehicles and provides rail vehicle side walls and rail vehicles. The side wall of the rail vehicle comprises a plurality of uprights arranged side by side, the plurality of uprights include door uprights on both sides and a plurality of middle uprights between the door uprights, the lower ends of the door uprights are adapted to abut against the track On the underframe side beam of the vehicle, the lower end of the middle column is arranged opposite to the upper surface of the underframe side beam with a gap, and the middle column and the underframe side beam are connected by a connecting piece. The present invention adopts that the middle column does not contact the side beam of the bottom frame, and is connected by a connecting piece, which solves the technical problem that the gap between the side wall column (the middle column) and the side beam of the bottom frame is inconsistent, and the gap between some positions is large and cannot be welded.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to side walls of rail vehicles and rail vehicles. Background technique [0002] At present, during the manufacturing process of the stainless steel car body, when the side wall columns are welded to the underframe side beams, due to the deflection cannot be completely matched, the gaps between the side wall columns and the underframe side beams are inconsistent, and some positions have large gaps and cannot be welded. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a side wall of a rail vehicle, which solves the problem that when the side wall column is welded to the side beam of the chassis, the gap between the side wall column and the side beam of the chassis is inconsistent, and the gap at some positions is relatively large due to the in...
