Patent number: 11167609Abstract: 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.Type: GrantFiled: July 16, 2018Date of Patent: November 9, 2021Assignee: ZF FRIEDRICHSHAFEN AGInventors: Klaus Wallgren, Knut Heidsieck

Patent number: 7950727Abstract: A suspension arrangement for spring suspending a mass body (3) in relation to a substructure (1), for example, a driver's cabin (3) of a heavy goods vehicle in relation to the vehicle chassis (1) thereof. The suspension arrangement comprises a spring/damper arrangement (2) which is arranged between the mass body (3) and the substructure (1) and which is used to dampen thrusts and/or oscillations. The suspension arrangement in characterized in that it comprises at least one pantograph (6) which is used to reduce the freedom of movement of the mass body (3). The inventive suspension arrangement is constructively robust and can determine the provided freedom of movement of the mass body in a reliable manner and can dampen and/or prevent undesired movements in other spatial directions. The invention enables an economical and a reliable spring suspension, in particular, for a driver's cabin of heavy good vehicles, to be produced.Type: GrantFiled: June 16, 2006Date of Patent: May 31, 2011Assignee: ZF Friedrichshafen AGInventors: Felix Haeusler, Holger Lohmüller, Knut Heidsieck
