Abstract: An auxiliary cross-member structure for supporting elements of a motor-vehicle front suspension includes a metal sheet hollow frame in a form of a hollow shell, with two opposite end portions, for connection of two respective oscillating arms of the suspension. The metal sheet hollow frame is defined by a single metal sheet folded on itself and having portions which are overlapped and welded. In a preferred implementation, within the metal sheet hollow frame is provided an additional filling structure at least partially constituted of synthetic material or composite material incorporating reinforcing fibers. At each end of the auxiliary cross-member structure there are two pairs of holes aligned with each other along two vertical axes which are used both for mounting elastic bushings for connection of a respective oscillating arm, and for the engagement of connecting screws for connecting the auxiliary cross-member structure to the motor-vehicle body.
