  • Patent number: 11167609
    Abstract: A vehicle axle with a centrally arranged drive unit and a wheel suspension which has a wheel carrier for holding a wheel, a lower wheel-guiding control arm for the articulated connection of the carrier to a vehicle body, a camber link that connects the carrier to the body and steering unit for steering the wheel. The carrier and control arm are connected directly, in a first connection area, and indirectly via an integral link, in a second connection area, so that the carrier can pivot relative to the control arm about a steering axis. The control arm can be connected to the body in forward and rear areas, and has a rotational axis that extends obliquely relative to the longitudinal direction of the vehicle. All connection areas of the control arm are positioned outside the centrally arranged drive unit relative to the transverse direction of the vehicle.

  • Patent number: 11167610
    Abstract: A wheel suspension (1) for a motor vehicle that has a wheel carrier (2) for holding a wheel (3), a wheel-guiding control arm (4) for the articulated connection of the wheel carrier (2) to a body (6), and steering member (8) for steering the wheel (3). The wheel carrier (2) and the wheel-guiding control arm (4) are directly connected, in a first connection area (20), and indirectly connected, in a second connection area (21), by an integral link (5) so that, relative to the wheel-guiding control arm (4), the wheel carrier (2) can pivot about a steering axis. The wheel suspension is characterized by a chassis element (12) that is articulated on a body side and is directly connected to the wheel carrier (2).

  • Patent number: 11142032
    Abstract: A wheel suspension (1), for a motor vehicle, having a hub carrier (2) for holding a wheel (3), a wheel-guiding link (4) for an articulated connection of the hub carrier (2) to a body (6), and a steering rod (8) for steering the wheel (3). The hub carrier (2) and the wheel-guiding link (4), for steering the wheel (3), are pivotally connected to each other such that the hub carrier (2) can be swiveled about a steering axis relative to the wheel-guiding link (4). The hub carrier (2) is directly connected to the wheel-guiding link (4), in a first connection area (20), and the hub carrier (2) is indirectly coupled to the wheel-guiding link (4), in a second connecting area (21), via an integral link (5) connected to a chassis element (12).

  • Patent number: 10035393
    Abstract: A wheel suspension for a motor vehicle, including a wheel carrier (2) for holding a wheel (3), a wheel-guiding control arm (4) for articulating the wheel carrier (2) to a structure, and steering member (23) for steering the wheel (3). For steering the wheel (3), the wheel carrier (2) and the wheel-guiding control arm (4) are articulated to one another in such manner that the wheel carrier (2) can pivot relative to the wheel-guiding control arm (4) about a steering axis. The wheel carrier (2) is connected indirectly to the control arm (4) in a first connection zone (20) by an integral link (5).
