Abstract
The invention relates to a subframe, in particular front axle subframe, for a vehicle, in particular electric vehicle, having a first shell element and a second shell element which is rigidly connected to the first shell element and defines a cavity therewith. At least one of the shell elements has a side wall which, as an outer wall of the subframe, is connected to the other shell element or to another of the shell elements in a materially bonded manner having at least one bushing-like or sleeve-like spacer element for the insertion of a fastening bolt, preferably a screw bolt, for connecting to a body or component. The spacer element is arranged at one of its ends at a through-hole of the first shell element and extending inside the cavity in the direction of a through-hole of the second shell element. In order for the subframe to provide greater stability, in particular improved safety against failure of weld seams at the body connection and/or component connection, e.g. transverse bridge connection, with less or only slightly increased weight, the invention provides that the side wall of the shell element has at least one tab which is welded to the spacer element. This allows at least one additional load path to be implemented in a direction parallel to the longitudinal center axis of the spacer element.
