Embodiment Construction

[0025] A first embodiment of a rear axle 10 of a motor vehicle according to the invention is shown in FIGS. 1 and 2 . Since it is driven, the rear axle 10 of the motor vehicle can be coupled to the drive train of the motor vehicle. As can be seen from FIG. 1 , the rear drive axle 10 of the motor vehicle is designed as a combined drag axle with two rigid longitudinal struts 12 that support the wheels and are elastically articulated to the vehicle body and a bending-resistant but torsionally flexible cross-member 14 .

[0026] Here, the trailing arms 12 are each pivoted about at least one pivot axis 16 . The crossbar 14 is provided in its central region with an open profile which transitions into a closed profile at the ends of the crossbar 14 . The crossbar 14 is arranged at a distance from the pivot axis 16 and is arranged in front of the center of the wheel when viewed in the longitudinal direction of the vehicle.

[0027] The crossbar 14 is welded to the trailing rod 12 in...

Abstract

The propelled vehicle rear axle (10) is coupled with a motor vehicle drive chain. The propelled vehicle rear axle is designed as torsion beam axle with two longitudinal trailing links (12) elastically attached to vehicle body and a torsion rigid, torsion smooth transverse rod (14). The longitudinal trailing links is oscillating around a swiveling axis (16). The transverse rod has a single piece tube profile or an open profile over its entire length. The transverse rod is angulated upwards, to operate a module assigned to the drive chain by distance for the assembly.

Description

technical field [0001] The invention relates to an automobile drive rear axle, which can be coupled with the automobile drive train. The invention also relates to a motor vehicle with such a motor drive rear axle. Background technique [0002] Hitherto known motor vehicle rear axles of motor vehicles consist of a large number of sheet metals, which leads to relatively high costs for assembly and welding. In addition, the fatigue strength of the welded sheet is also a key factor. Axles with a crank-shaped twist profile have already been proposed, wherein the crank-shaped twist profile is used not only in all-wheel-drive vehicles, but also in non-all-wheel-drive vehicles. However, these shafts all comprise a large number of plates, again leading to the aforementioned drawbacks. Contents of the invention [0003] The technical problem underlying the invention consists in designing an improved drive rear axle of a motor vehicle and an improved motor vehicle of the aforement...
