For rail vehicle - outer wall of carriage and manufacturing method

Abstract

The invention relates to a method for producing an outer wall module or an outer wall (1) or a coach body of a railway vehicle, and to an outer wall, an outer wall module, and a coach body of a railway vehicle. The following steps are provided for producing an outer wall (1) or an outer wall module: assembling 2-dimensional sheet metal parts (10, 11) having different properties (15, 16) into an outer sheet metal shell (3) designed as a self-supporting thrust area module, wherein the end faces of the sheet metal parts (10, 11) are each oriented transverse to the 2-dimensional extension of the individual sheet metal parts (10, 11) abut one another and are assembled by penetrating laser weld seams (13) in such a manner that the individual sheet metal parts (10, 11) form a flush outer surface (17) on an outer face of the thrust area module, wherein the sheet metal parts (10, 11) having different properties (15, 16) comprise first sheet metal parts (10) and second sheet metal parts (11), and the second sheet metal parts (11) each comprise a greater resistance, in particular strength and / or greater material thickness (15) than the first sheet metal parts (10), and the second sheet metal parts (11) are inserted in regions of the outer sheet metal shell (3) at which increased stresses occur during operation of the railway vehicle in a coach body produced from the outer wall module or the outer wall (1), and a structure (4) is created from rib profiles (5, 5a, 5b), wherein end face butt edges (19, 20, 21) of the rib profiles (5, 5a, 5b) adjoin the inner face (17) of the outer sheet metal shell (3) by means of T-joints, and are fastened to the outer sheet metal shell (3) by means of laser weld seams (13).

Description

technical field [0001] The invention relates to an outer wall for a rail vehicle car and an outer wall module for such an outer wall as well as to a method for producing such an outer wall module or outer wall of a rail vehicle car and to a rail vehicle car itself. Background technique [0002] Carriages for rail vehicles are known from the prior art, which have a frame made of various components, such as longitudinal beams, beams and columns, which is provided with outer panels to thereby form the outer walls of the car. In the prior art, the wagon body has hitherto been constructed in such a way that the frame comprises load-bearing sheet metal elements which form a lattice frame. In these compartments are inserted panels which then together with the components of the frame form the outer walls of the carriage. Such a carriage is described, for example, in DE 10 2008 048 083 A1. This document also describes the production of a sheet metal element consisting of at least ...

Problems solved by technology

The disadvantage of this process is that the cover plate is broken during this process, so that the external appearance and surface properties of the surface of the planar element are adversely affected
