The present invention relates to an axle carrier 1 and to a method for the production of the axle carrier 1. The axle carrier 1 has an upper shell 2 from an aluminum die-casting and a lower shell 3 from a fiber composite material. On a ribbed structure of the lower shell 3, an upper end 14 of the reinforcing ribs 9 is preferably configured so as to be widened such that the bearing face between the reinforcing rib 9 and the upper shell 2 is enlarged and, on account thereof, the strength of the axle carrier 1 produced is increased.

A trailing arm device (1) of a drivable torsion beam axle (2) is described. The trailing arm device (1) has a housing (5) in which a drive-train (8) can be arranged and is connected to a trailing arm (4). The housing (5), as fitted into position within a vehicle, has a sidewall (11) formed integrally with a central housing region (9) on a side facing toward a wheel. The sidewall delimits a housing interior space (10) that accommodates, at least partially, the drive-train (8). On the side facing away from the wheel, the housing interior space (10) is delimited by at least one cover element (14) that can be detachably connected to the central housing region (9).

A tubular type torsion beam is manufactured by bending and welding and coupling a plate material. The plate material has a plurality of protrusions disposed on a plurality of side surfaces in a width direction of the vehicle. The torsion beam is manufactured by molding the plate material in a pipe shape by bending the plate material in the width direction and molding the plate material to dispose the plurality of protrusions to contact each other to form a gap between the plurality of side surfaces of the plate material and then welding and coupling the plurality of side surfaces of the plate material.

This torsion beam manufacturing method is a method of manufacturing a torsion beam that includes a uniformly shaped closed cross-sectional portion of which a cross section orthogonal to a longitudinal direction is a closed cross section having a substantial V-shape or a substantial U-shape at any position in the longitudinal direction, and a shape changing portion which has a connection region leading to the uniformly shaped closed cross-sectional portion and including a closed cross section having a shape different from the shape of the closed cross section of the uniformly shaped closed cross-sectional portion. The torsion beam manufacturing method includes pulling process of applying a tensile force in the longitudinal direction to at least the connection region of a torsion beam material including the uniformly shaped closed cross-sectional portion and the shape changing portion, to obtain the torsion beam.

The invention relates to a twist-axle that includes a cross-beam member and two trailing arms, each trailing arm rigidly secured to the cross-beam member in one of two connection regions of the cross-beam member or formed integrally with and extending from one of the two connection regions. The cross-beam member is formed from a tubular blank and has a torsionally elastic central portion and two torsionally stiff connection regions. The cross-beam member has a wall thickness that varies longitudinally along the length of the cross-beam member from the torsionally elastic central portion to each of the torsionally stiff connection regions.

The disclosure relates to a method for producing an axle component for a motor vehicle, in which at least two metallic axle parts are joined integrally to one another. The axle component is a twist beam axle, in which lateral trailing arms are connected to each other via a transverse profile. In order to establish a target geometry of the axle component, the heat induced by a welding operation is utilized. The welding operation can be a specifically positioned weld, an additional weld or a blind weld. The heat of welding is utilized in order to achieve a compensation deformation and to compensate for distortion states and/or to align the axle component.

A twist axle assembly (20) of a vehicle includes a pair of trailing arms (22) and a twist beam (24) having a base portion (46) extending along an axis (A) between first and second twist beam ends (42, 44). The twist beam (24) includes a pair of side walls (48) extending downwardly from the base portion (46) and each disposed in spaced relationship with the trailing arms (22). At least one mounting bracket (54) extends from a first mounting bracket end (56) disposed in abutting relationship with a respective trailing arm (22) to a second mounting bracket end (58) disposed in overlaying relationship the side walls (48) of the twist beam (24) for allowing the mounting bracket to axially slip or slide along the side walls (48) of the twist beam (24) and provide for lateral or axial adjustment of the twist axle assembly (20) during the manufacturing process.

A motor vehicle body has an underbody and a link, which at one end is pivotably connected to the underbody and at another end carries a wheel. The connection to the underbody includes an underbody-side bearing support, in which a link-side pin engages.

A coupled torsion beam axle for buckling induction may include a torsion beam, a cross section of which varies laterally, a right axle coupler and a left axle coupler being respectively formed at both end portions of the torsion beam, the torsion beam being provided with a buckling induction member configured to induce buckling deformation by an external load applied to each of the right and left axle couplers.

A motor drive device includes: a trailing arm that extends in a vehicle front-rear direction and includes a vehicle body-side attachment portion and wheel-side support portion, the vehicle body-side attachment portion formed on a forward portion side of the trailing arm and coupled to a vehicle body via a rubber bush, the wheel-side support portion formed on a rear side of the trailing arm and supporting a rear wheel; and a motor that is supported by the trailing arm and drives the rear wheel. The motor and the rubber bush are disposed in such a way that motor and the rubber bush are seen as being substantially aligned in a vehicle up-down direction when viewed in a vehicle width direction.
