PLANAR ELEMENT AND METHOD FOR PRODUCING A PLANAR ELEMENT

摘要

The invention relates to a method for the production of a planar element (2) for differential bodies, comprising outer planking (4) and at least one plan ar reinforcing means. Profiled sections (10) and nodes (10) are provided in a given arrangement on the outer planking (4). In a first step, the reinforcin g means is glued to the outer planking (4). In a second step, the profiled sections (10) and nodes (10) are arranged and are at least partially joined in a cold joining process to form a frame. In a third step, the frame is at lea st partially joined to the outer planking (4) on the side of the reinforcing means in a cold joining process . The sheet metal thus obtained exhibits a high buckling resistance.
