Torsion beam axle for a vehicle, and bearing arrangement for a torsion beam axle

Abstract

The present disclosure provides a torsion beam axle for a vehicle. The torsion beam axle comprises two longitudinal swing arms connected by a torsion profile and two bearing arrangements. Each bearing arrangement is configured to attach a respective longitudinal swing arm to a body of the vehicle. Each bearing arrangement has a rotational axis, and the rotational axes of the bearing arrangements run in parallel to or are aligned with one another. Each of the bearing arrangements has a bearing core, which is connected to one of the longitudinal swing arms, and at least one bearing arm which is coupled to the bearing core. The bearing arm comprises a supporting section, which is coupled to the bearing core, and an elastic bending section with a connecting region, via which the bearing arm can be at least indirectly attached to the body of the vehicle. The bearing arm has a step portion arranged between the supporting section and the bending section, the step portion having a triangular or trapezoidal contour and being configured to be deflected in a bending direction which is predefined by the bending section. The bending direction and the rotational axes enclose an angle between them.
