Longitudinal support arrangement for motor vehicle, has coupling part comprising reinforcement element i.e. closed extruded section, which counteracts deformation of coupling part in vehicle longitudinal direction

摘要

The arrangement (12) has an upper longitudinal support (14) and a lower longitudinal support (16) that is arranged below the upper longitudinal support in a vehicle height high direction. A coupling part (18) is connected with the upper longitudinal support and the lower longitudinal support. The coupling part has a reinforcement element i.e. closed extruded section, which counteracts the deformation of the coupling part in a vehicle longitudinal direction. The coupling part and/or one of the longitudinal supports is made of aluminum alloy.
