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 present invention relates to a powered motor vehicle rear axle (10) that can be coupled with a motor vehicle drive train. The powered motor vehicle rear axle is configured as twist-beam rear axle with two wheel carrying resistant trailing arms (12) that are elastically linked to the motor vehicle structure and a bending resistant, but torsion flexible cross member (14). The cross member (14) is composed of open section material in its entire length, and is welded to the trailing arms in the area of its both ends. The cross member is bent upwards to make space for the installation of at least one module allocated for the drive train, for example for the installation of a drive shaft and a rear axle differential. The cross member (14) is at least provided with open section material in its center including a first sectional arm (26) and a second sectional arm (28), at least most of the section material is guided to a half cavity which locates on the top of a plane being tense on the top area of the two sectional arms (26, 28), wherein the plane is parallel to the powered motor vehicle crossshaft and longitudinal shaft.

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...
