Abstract
A vehicle rigid axle with an axle beam, at the ends of which axle journals or wheel carriers, respectively, are arranged, and with at least two trailing arms rigidly attached to the axle beam and with at least one air spring bellows assigned to the respective trailing arm. At least one component of an electric drive is placed in the hollow body, the drive shaft of which passes through the axle journal. To form at least one axle journal connection section extending between the two trailing arms, a trailing arm connected thereto and a receptacle for at least one component of an electric drive, two shell elements are formed from sheet metal and connected to one another, in particular welded, to form a hollow body surrounding the receiving space. At least one component of the electric drive is mounted in the receiving space.
