A fabricated torque arm for use in a vehicle suspension, including a rod having a solid rectangular cross-section, the rod having a first end and an oppositely disposed second end, a first bushing hub, and wherein the rod is only a single piece cut from a metal plate or sheet, wherein the first bushing hub comprises cut tubing, wherein the first end of the rod has a radius that conforms to an outer surface of the first bushing hub, and wherein the first end of the rod is welded to the outer surface of the first bushing hub.

The invention relates to a method for producing a bent torsional profile comprising the following process steps: a) provision of a plate made of planar sheet metal, b) reshaping of the plate through the introduction of a bent trough oriented in the longitudinal direction of the plate in a central length portion (6) of the plate at a distance from the front edges of the plate, forming legs between the trough and the longitudinal edges of the plate, c) reshaping of the legs in such a manner that an open profile is created, d) reshaping of the legs in such a manner that a hollow profile is produced, wherein a longitudinal gap is formed between the two legs over the entire longitudinal extent thereof and wherein an air gap is created between the legs and the trough in the region of the trough, e) joining of the two legs over the entire longitudinal gap.

This torsion beam manufacturing method is for manufacturing a torsion beam including a central 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 central portion and including a closed cross-section having a shape different from the shape of the closed cross-section of the central portion. This torsion beam manufacturing method has a compression step of thickening at least the connection region through application of a compression force in the longitudinal direction to at least the connection region of a torsion beam material to obtain the torsion beam, the torsion beam material being formed with the central portion and the shape changing portion.

A hollow stabilizer includes a curved part having eight regions defined in a cross section. A first region includes a 90° first part when the center of the inside of the curve is taken to be at 0° and the center of the outside of the curve is taken to be at 180°. A third region includes a 0° third part. A fifth region includes a 270° fifth part. A seventh region includes a 180° seventh part. The radii of curvature of the respective outer surfaces of the third part and the seventh part are larger and the radii of curvature of the respective outer surfaces of the second part and the sixth part are smaller than the radii of curvature of the respective outer surfaces of the fourth part and the fifth part.

A swing arm having a reduced number of parts in which manufacturing cost can be reduced. In a swing arm including: vehicle-body-side support portions that are supported on a vehicle body side by a first rotary shaft; wheel-side support portions that are supported on a wheel side by a second rotary shaft; and a pair of arm portions that connect the vehicle-body-side support portions and the wheel-side support portions to each other, cross members that extend in an axial direction of the first rotary shaft is arranged on the pair of arm portions so as to extend between the pair of arm portions, and the cross members have a U shape in cross section orthogonal to a longitudinal direction of the cross members, thus forming opening portions that open so as to face a direction that the pair of arm portions extends.

Axle seat assemblies and methods of manufacturing thereof, are provided for attachment to an axle body (15). The axle seat assembly may be comprised of a first piece (42) and a second piece (50). The first piece (42) may have a first wall, a second wall and a first axle seat piece engagement portion providing a first engagement surface. The second piece (50) may have a third wall and a second axle seat piece engagement portion providing a second engagement surface. The first wall and the second wall of the first piece are oriented to engage a front surface of an axle body and the third wall of the second piece is oriented to engage a rear surface (30) of an axle body. The first and second engagement surfaces of the respective first and second pieces of the axle seat assembly are positioned and configured to engage one another to removably and reversibly secure with the use of a fastener the first piece to the second piece to form an axle seat assembly.

The invention provides a production method for stabilizers which produces with high productivity in a compact production line, without tempering. The production method for stabilizers of the invention includes: forming a steel bar material containing at least C: 0.15 wt % to 0.39 wt %, Mn, B and Fe into a product shape by bending; and quenching the bent steel bar material in a medium having a heat transfer coefficient higher than or close to that of water.

A structural component for a motor vehicle, with a component body (2) made from a sheet, which includes at least one shell-shaped body portion (3) formed from the sheet and at least one receiving bush (6) formed from the sheet that extends along its circumference between first and second circumferential ends (4, 5), which at the first circumferential end (4) merges into the shell-shaped body portion (3) and at the second circumferential end (5) merges into a strengthening strip (7) formed from the sheet and attached to the shell-shaped body portion (3). The strengthening strip (7) completes the shell-shaped body portion (3) to form an at least partially closed hollow section (8).

The disclosure relates to an elongate link arm member of a support link arm. A ball joint socket is disposed on a first longitudinal and of the link arm member. The link arm member in a sheet-metal shell construction mode is formed from sheet metal and has a cavity portion. The ball joint socket is a forging or casting from metal and possesses a fastening appendage which is configured in a materially integral manner so as to be in one piece with said ball joint socket. The ball joint socket by way of the fastening appendage engages in the cavity portion of the link arm member and is joined to the link arm member.
