It is formed of a one-piece tubular structure, the central region forming the transverse portion (3) being so profiled as to present at least one double-wall flange portion, a bent region (12, 13) being provided at each end of the transverse portion, each bent portion being extended by an arm (14, 15) at the end of which is provided the fixing for the stub axle. The invention also relates to a process for producing the foregoing axle. The axle according to the invention can be used in particular as the back axle assembly of a motor vehicle.
