Motor vehicle having a modular structure and a method for assembling it

In a rear axle for motor vehicles, which includes a torsionally-yielding cross member fixed at its ends to two trailing arms carrying the wheel spindles, the cross member has a channel section with a base wall which is disposed upwardly, and two downwardly-inclined end portions. To the ends of the cross member are fixed two tile-shaped reinforcing members which, together with the inclined end portions of the base wall of the cross member, form two box structures defining two bracket-shaped connecting parts in which the two trailing arms are engaged and welded. The tile-shaped reinforcing members are provided with supports for a pair of helical suspension springs of the axle.
