Axle system for articulated assembly of vehicle axles in motor vehicles has axle strut body and articulation body each made from one-piece closed hollow profiled section

摘要

The axle system has an axle strut body (1) and at least one articulation body each made from a one-piece closed hollow profiled section. The axle strut body has a cross-sectional surface (10) which changes in the longitudinal direction. The middle area (11) of the axle strut body can have a rectangular, star-shaped or polygonal cross-sectional surface. Independent claim describes method for making axle system where hollow profile is re-formed by hydro-forming into axle strut and articulated bodies
