Abstract
A suspension actuator includes an upper mount, a lower mount, a first actuator mechanism, and a second actuator mechanism. The upper mount is connectable to a sprung mass of a vehicle. The lower mount is connectable to an unsprung mass of the vehicle. The first actuator mechanism forms a first load path between the upper mount and the lower mount. The first actuator mechanism is one of an electromagnetic linear actuator mechanism or a ball screw actuator mechanism. The second actuator mechanism forms a second load path in parallel with the first load path between the upper mount and the lower mount. The second actuator mechanism is one of a mechanical linear actuator mechanism, an air spring actuator mechanism, or a hydraulic actuator mechanism.
