Longitudinal bearer for the chassis of motor vehicles

摘要

A longitudinal bearer for the chassis of motor vehicles which is formed of symmetrical sheet metal troughs or similar deep-drawn profiles having edges, and which is connected together by flanges projecting out of the approximately rectangular cross section at two opposte sides of the bearer; the width dimensions of the trough bottom walls of the parallelepiped which is assembled from the two sheet metal troughs and forms the bearer are reduced in the longitudinal direction in that the connecting walls between the flanges and the bottom walls extend increasingly inclined to the contours of the parallelepiped and thereby become wider in the mentioned longitudinal direction.
