The invention relates to an auxiliary frame for a vehicle, in particular an electric vehicle, with a longitudinal member composed of metal sheets, which has bearing connection points for a transverse control arm connection, the bearing connection points being formed in a bearing section of the longitudinal member which is open towards the wheel carrier side, wherein the bearing section is formed from a first single-shell metal sheet and a second single-shell metal sheet, wherein the second single-shell metal sheet is connected to the first single-shell metal sheet by a weld seam, wherein the first single-shell metal sheet has at least one of the bearing connection points, and wherein the second single-shell metal sheet has at least one of the bearing connection points. In order for the auxiliary frame to have a significantly higher stability, in particular higher bending strength and/or rigidity, with the same or only slightly increased weight, the invention provides that the first single-shell metal sheet, when viewed in cross-section, has a substantially Z-shaped shell section which has a profile section facing the wheel carrier side, a profile section facing away from the wheel carrier side and a profile section which connects the two profile sections to one another in one piece and is substantially upright in the assembled state of the auxiliary frame, wherein the weld seam is arranged at a distance from the substantially upright profile section on the profile section facing away from the wheel carrier side.
