Abstract: A longitudinal member is provided. The longitudinal member includes a front end provided with a hinge element for attaching the longitudinal member in an articulated manner to a heavy goods vehicle body, and a rear end including an attachment element for attaching the longitudinal member in a non-permanent manner to the heavy goods vehicle body. The longitudinal member includes a front part extending from the front end to an intermediate area of the longitudinal member and a rear part extending from the intermediate area to the rear end of the longitudinal member. The product (PF) of the wall thickness (tF) of the front part by the yield strength (YsF) of the material of the front part is greater than the product (PR) of the wall thickness (tR) of the rear part by the yield strength (YsR) of the material of the rear part.
