A transverse or oblique link is provided for a front vehicle axle. The link contains a first and a second link arm, the first link arm has a deformation section situated at a front in the direction of travel and a section situated behind it in the direction of travel. Furthermore, the first link arm is configured in such a manner that, in an accident, it is deformed in an energy-absorbing manner predominantly in its deformation section. In order to force a deformation in the deformation section, the flexural rigidity of the section about a bending axis running in the transverse direction of the vehicle is increased in comparison to the flexural rigidity of the deformation section. Upon contact with a curb, the two sections can be deformed in an energy-absorbing manner.
