Abstract

A subframe for a motor vehicle has two side plates which extend in the longitudinal direction of the vehicle, are connected with one another by cross members and have bearings for control arms of wheel suspension links, this subframe unit being connected with the vehicle body. The side plates are each formed of a torsion-proof and rigid lattice frame which extends in a vertical longitudinal plane of the vehicle. Between the side plates, torsion-proof cross members are held which can each be screwed on separately in a detachable manner. Together with the side plates, these cross members form a rigid assembly unit which comprises integrated bearings for control arms of wheel suspension links in the side plates. By way of one bearing respectively, which is arranged in spaced horizontal planes in a top and bottom chord of the side plate, the subframe unit is detachably fastened on the vehicle body.
