Abstract
The invention concerns a process for assembly of the end of a girder (16,18',18',20', 20'and the associated region of a crossbrace (10,12), constituting components of the chassis end of a railway vehicle, with the girder and crossbrace each comprising at least one vertical web and upper and lower flanges. According to the invention, the flanges of the girder are cut away such that its web extends longitudinally beyong the edges of the flanges. Then the flanges of the crossbrace are cut so as to form attachment journals with free edges adapted to the respective free edges of the flanges of the girder, at the same time, forming in the region of the free edges, hook-shaped lateral appendages. The crossbrace and girder are positioned so that the respective free edges of the flanges of the crossbrace and the girder essentially abut one another, and the girder and crossbrace are welded together in the regions of mutual contact.
