    摘要： A joint assembly couples a linear actuator to a body. The joint assembly includes a first body having a first surface and a second body having a second surface. The first body is coupled with the second body. The first surface and the second surface have arcuate configurations that are complementary to facilitate rotation of the first body relative to the second body about a first axis, a second axis, orthogonal to the first axis, and a third axis, orthogonal to both the first axis and the second axis. The joint assembly also includes a damper disposed between the first body and the second body and configured to dampen translational motion of the first body toward the second body in response to movement of the linear actuator relative to the body.

    摘要： 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.

    摘要： A vehicle includes a vehicle structure, a wheel assembly, a control arm that is connected to the wheel assembly and the vehicle structure by pivot joints, and an active suspension actuator that is connected to the control arm and to the vehicle structure. The vehicle also includes an air reservoir that includes a first port and an air spring that supports the vehicle structure with respect to the control arm and is able to compress and expand. The air spring includes an internal working volume, the air spring includes a second port that is in fluid communication with the internal working volume, and the second port is connected to the first port to allow exchange of air between the internal working volume of the air spring and the air reservoir in response to compression and expansion of the air spring.

    摘要： A suspension system for a vehicle that has a vehicle body, a first wheel assembly that includes a first wheel hub, and a second wheel assembly that includes a second wheel hub. The suspension system includes a crossbar that is pivotally connected to the first wheel hub of the first wheel assembly and is pivotally connected to the second wheel hub of the second wheel assembly. The suspension system also includes a first active suspension actuator that is located near the first wheel assembly, is connected to the vehicle body, is connected to the crossbar, and supports the vehicle body with respect to the crossbar. The suspension system also includes a second active suspension actuator that is located near the second wheel assembly, is connected to the vehicle body, is connected to the crossbar, and supports the vehicle body with respect to the crossbar.

    摘要： A suspension system includes a primary actuator, an inertial actuator, and a controller. The primary actuator applies force between a sprung mass and an unsprung mass of a vehicle to control movement therebetween. The inertial actuator applies force between the unsprung mass and a reaction mass to damp movement of the unsprung mass. The inertial actuator has a threshold capacity. The controller controls the primary actuator and the inertial actuator. The controller determines a required damping of the movement of the unsprung mass, and apportions the required damping between the primary actuator and the inertial actuator.
