VEHICLE FRONT RAIL

Abstract

A front rail configured to be supported by a vehicle frame includes a tubular body made of cold-rolled, high-strength metal and configured to withstand axial loading during a frontal vehicle impact. The high-strength metal defines a cross-sectional shape along the length of the tubular body. The tubular body includes a center wall extending from a first side wall to a second side wall, defining at least one first longitudinal hollow channel and one second longitudinal hollow channel. A first crush initiator is disposed in the first side wall of the tubular body in a first crush area and is formed in the high-strength metal before the tubular body is cold-rolled.A second crushing initiator is arranged at the corners of the tubular body in a second crushing area and is formed in the high-strength metal after cold rolling the tubular body.
