Abstract

A drive shaft for motor vehicles comprises shaft portions arranged one after the other in s longitudinal direction of the drive shaft. One shaft portion is a tubular shaft portion having a large cross section and another shaft portion having a cross section that is smaller than the tubular shaft portion having a large cross section. A transition region having a region wall is provided between the tubular shaft portion and the shaft portion having the smaller cross section. If the drive shaft is compressed in the event of a crash, the shaft portion having the smaller cross section is pushed into the tubular shaft portion having the large cross section by an insertion length, thus deforming or breaking the region wall of the transition region.
