The transverse tube has a main tube located between the side parts, a left end piece assigned to the left side part and a right end piece assigned to the right side part. The main tube is connected to the two end pieces in respective overlapping regions. The main tube is manufactured from a material, preferably from steel, which has an at least 20% higher tensile strength than the material of the end pieces.
