Embodiment Construction

[0024] the only attached figure 1 A plan view is shown of a battery tray 1 of a motor vehicle 3 driven by means of an electric motor 16 and having a torsion beam axle according to the invention arranged thereon. here, in figure 1 In the illustration of , only the left-hand torsion beam axle is provided with reference numerals, since the right-hand torsion beam axle is correspondingly only designed as a mirror image of the left-hand torsion beam axle.

[0025] Here, the torsion beam axle essentially consists of two longitudinal links 6 and 7 , which are connected to one another via a cross member 2 . The transverse beam 2 is designed here as a bending-resistant and torsion-flexible torsion profile. The longitudinal links 6 and 7 are arranged on the battery tray 1 and connected to it by means of rubber bearings 8 and 9 . At their ends opposite the rubber bearings 8 and 9 , the longitudinal links 6 and 7 have wheel carriers 4 and 5 , on which wheels 17 and 18 can be respective...

Abstract

The invention relates to a twist-beam axle for an electrically driven motor vehicle (3) which is provided on the motor vehicle floor with at least one battery tray (1), having longitudinal links (6, 7) which are each assigned to a wheel carrier (4, 5) of the axle and which are connected to one another via a crossmember (2) and at one end of which a respective wheel carrier (4, 5) is arranged, wherein the longitudinal links (6, 7), at the end opposite to the respective wheel carrier (4, 5), are connected by means of rubber bearings (8, 9) to the battery tray (1) arranged on the motor vehicle floor, to a longitudinal member or crossmember in the floor region of the motor vehicle (3) or to a frame of the motor vehicle (3).

Description

technical field [0001] The invention relates to a torsion beam axle for an electrically driven motor vehicle. Background technique [0002] A wheel suspension for steerable front wheels is known from DE 31 18 177 A1, in which a torsion beam axle is used, wherein the longitudinal or tilting links articulated on the wheel carrier Hinged to the body via rubber bearings. However, the problem of height differences between the vehicle's center of gravity and roll center still exists in the wheel suspension, as a result of which the vehicle again oscillates strongly when driving in a curve. Contents of the invention [0003] It is therefore the object of the present invention to provide a wheel suspension or torsion beam axle for an electrically driven motor vehicle in which strong oscillations when driving in curves are reduced, the wheels The suspension or torsion beam axle also consists of a small number of parts and can thus be easily assembled without complex assembly work...
