Embodiment Construction

[0056] figure 1 A motor vehicle axle 1 according to the invention is shown. The motor axle 1 comprises two trailing arms 2 and a cross member 3 connecting the two trailing arms. The trailing rods 2 each have a connecting portion 4 connecting the trailing rods 2 to the vehicle body. In addition, the trailing arm 2 is provided with a connection 5 to the wheel carrier.

[0057] Furthermore, the motor axle 1 has a spring seat 6 with which a coil spring can be accommodated.

[0058] The beam 3 comprises an open profile 7 with a U-shaped cross-section. The profile 7 has a web 10 and two legs 11 , 12 bent from this web on the longitudinal sides. The characteristic here is that the side 11 on the front side of the vehicle (that is to say the side pointing in the direction of travel X) is located at the end section E of the profile 7 . 1 ,E 2 The inside has a reduced height H relative to the middle section M of the profile 7 .

[0059] Along the length L of the beam 3, the end s...

Abstract

The invention relates to an axle (1) of a motor.The axle (1) of a motor comprises two longitudinal control arms (2) and a connecting crossbeam (3) connected to the two longitudinal control arms. The crossbeam (3) includes a profile (7) with a U-shaped cross-section opening, the profile is provided with a web (10) and side limbs (11,12) blending from the longitudinal side of the web. The opening of the profile (7) in the installation position points to a road. The side limb (11) on the front side of a vehicle is in the end portions (E1, E2) of the profile (7) and has a reduced height (H) relative to a central portion (M) of the profile (7). The height (H) of the side limb (11) on the front side of the vehicle changes through a longitudinal side, circular arc or elliptical arc recess (9). The invention also relates to a method for the manufacture of a crossbeam (3) for an axle (1) of a motor

Description

technical field [0001] The invention relates to a motor vehicle axle comprising two trailing rods and a cross member connecting the two trailing rods, wherein the cross member comprises an open profile with a U-shaped cross-section, the profile having a web and on the longitudinal sides From the bent side of the web; the opening of the profile points towards the driveway in the installed position. Furthermore, the invention relates to a method for producing a cross member of a corresponding motor vehicle axle. Background technique [0002] The axle structure according to the invention is often also referred to as a composite steering axle. Very specific requirements are placed on it: to produce a predetermined driving characteristic and corresponding driving comfort. [0003] Numerous variants are known in the prior art when designing cross members of composite steering axles. For example, WO 2013 / 185217 A1 or DE 10 2007 058 582 A2 disclose cross members for motor vehicle...
