Abstract: A wheel suspension for a two-track motor vehicle includes a multi-link assembly having control arms that are articulated on a vehicle body and on a wheel carrier, a rotary actuator for an active suspension control system, with a motor-gear-unit constructed to transfer torques as actuating forces to the multi-link assembly via a torsion rod, and at least one reinforcing brace independent of the multi-link assembly and disposed on a side of the vehicle body and extending below the multi-link assembly, as viewed in a vertical direction of the vehicle body. The reinforcing brace delimits downwardly in the vehicle's vertical direction a free space, in which the rotary actuator is at least partially arranged.

Abstract: A stabilizer arrangement in a wheel suspension for a motor vehicle includes a rotatably supported center part oriented in the vehicle transverse direction, and at least one leg projecting from the center part in the vehicle longitudinal direction and articulated via a substantially vertically extending rod with a control arm of the wheel suspension. A joint connection is arranged between the rod and the control arm outside a vehicle longitudinal member by a transverse clearance in the vehicle transverse direction, when the vehicle is in the compressed state. The rod is articulated to the control arm such that its force vector extending through the joint connections of the rod extends through the center axis defined by the control arm bearings.

Abstract: A torsion bar spring arrangement for a wheel suspension of a motor vehicle includes an actuator arranged on a vehicle body or on a subframe and constructed to variably pre-tension the torsion bar spring arrangement, a coaxial first torsion bar spring having an output side that is connected by way of an output lever to a wheel suspension element of the wheel suspension, and a housing of the actuator supported on the vehicle body in at least one bearing location for movement in a circumferential direction and resiliently yieldingly supported on the vehicle body in the direction of torsional moments acting on the torsion bar spring by way of at least one spring element.

Abstract: The invention relates to an apparatus for reinforcing a supporting subframe for motor vehicles which is comprised of two longitudinal beams (30) and at least one crossbeam (32, 34), with the links (14, 16, 20, 22) of wheel suspensions on both sides being articulated to the longitudinal beams (30) via radially protruding, fixed mounts (36, 38) by rubber-metal sleeve bearings, and with the longitudinal beams (30) including at least in one region of articulation of a link (14) a longitudinally extending portion (30b) and a transversely extending portion (30c) which define in particular an approximately 90° curvature. According to the invention, the mounts (36, 38) are configured as two brackets, with one of which being supported on the longitudinally extending portion (30b) of the longitudinal beams (30) and the other one of which being supported on the transversely extending portion (30c).

Abstract: The invention relates to a subframe for the vehicle chassis of motor vehicles, which subframe has at least one cavity usable as a pressure accumulator and has a cross member (1) which is connected, at the two end faces (27, 28) thereof, to a node element (3, 4). Bearing elements (10 to 12) and/or further frame elements are attached to the node elements (3, 4). The cross member (1) is formed as a continuous rib-reinforced component or extruded part (15) and forms for the pressure accumulator a pressure-resistant cavity which is closed off by the node elements (3, 4) at the end faces.

Abstract: A sheet-metal control arm for a wheel suspension of a motor vehicle includes a base body, and two eyelets arranged in spaced-apart relationship at least at one end of the base body. Each eyelet has an opening, with the openings of the eyelets receiving a chassis bearing. At least one of the eyelets has a wall which is provided with a projection which is configured to at least partly bridge a gap to a wall of the other one of the eyelets.

Abstract: A wheel suspension for a rear wheel of a motor vehicle includes a wheel carrier, a lower control arm and a track rod connected to the wheel carrier at first and second points of articulation and supported on a vehicle body by first and second bearings. A rotation movement by the control arm and the track rod in response to longitudinal and/or lateral forces causes a toe-in change to thereby adjust the first point of articulation of the control arm by a first transverse offset in a vehicle transverse direction and adjust the second point of articulation of the track rod by a second transverse offset in the vehicle transverse direction. The first bearing is configured elastokinematically such that the first transverse offset of the first point of articulation is greater than the second transverse offset of the second point of articulation in response to the longitudinal and/or lateral forces.
