Abstract
A subframe for a motor vehicle axle optimized for stiffness and weight is provided. Such a subframe may comprise a base member, a cross member, and a stiffening element. The base member may have an upper shell, a lower shell connected to the upper shell, and a connecting point formed on one of the shells for a pendulum bearing of a pendulum bar. The cross member may extend in a transverse direction, be attached to the base member, and have mounts for longitudinal members of the motor vehicle. The stiffening element may be connected to at least one shell in a region of the connecting point. Also described is a production method for a subframe.

A subframe for a motor vehicle axle, comprising:
- a base member, the base member comprising an upper shell, a lower shell connected to the upper shell, and a connecting point, wherein the connecting point is located on at least one of said shells and configured for a pendulum bearing of a pendulum rod;
- a cross member, the cross member extending in a transverse direction and attached to the base member, the cross member arranged upstream from at least the upper shell of the base member relative to a forward direction of travel of a motor vehicle, the cross member having mounts, the mounts configured to couple with longitudinal members of the motor vehicle;
- bearing mounts for control arms of a wheel suspension, at least one of the bearing mounts arranged downstream from the cross member relative to the forward direction of travel, the hearing mounts formed at least in part by the base member;
- and
- a stiffening element, the stiffening element connected to at least one of said shells in a region of the connecting point.
