Abstract

In a method of making a control arm for a wheel suspension of a motor vehicle a blank of steel material having a tensile strength of at least 800 MPa is shaped, using a sheet metal forming process, into a shell body having a center web and plural flank portions extending from the center web in a same direction. The flank portions are connected by a latticed reinforcement made of plastic, without application of a heat treatment process.
