An electric drive system including: a rotary motor system including a hub assembly, a first rotating assembly, a second rotating assembly, and a third rotating assembly, wherein the hub assembly defines a rotational axis about which the first rotating assembly, the second rotating assembly, and the third rotating assembly are coaxially aligned and are capable of independent rotational movement independent of each other; a multi-bar linkage mechanism connected to each of the first and third rotating assemblies and connected to the hub assembly and constraining movement of the hub assembly so that the rotational axis of the hub assembly moves along a defined path that is in a transverse direction relative to the rotational axis and wherein the multi-bar linkage mechanism causes the rotational axis of the hub assembly to translate along the defined path in response to relative rotation of the first rotating assembly and the third rotating assembly with respect to each other.

Multi-bar linkage electric drive system

An exemplary actuator includes a motor, a transmission, and a support structure. The motor includes two torque sources that apply respective input torques to a rotor, which rotates about a rotation axis in response to a net input torque. The torque sources are arranged such that the input torques are additive, resulting in a vector-summated torque output. The torque sources also generate corresponding reactive torques that are applied to the first stator and the second stator. The transmission couples and constrains the first stator and the second stator such that rotational motion of one stator causes counter rotation of the other stator. Thus, the reactive torques are subtractive resulting a differential torque output. In some applications, the differential torque output is used to actuate a suspension of a vehicle. The actuator is also coupled to the vehicle via the support structure, which also reflects a reaction force or torque to actuate other subsystems (e.g., anti-dive, anti-squat).

Multi-input, multi-output actuator and assemblies using same

An electric drive system including: a rotary motor system including a hub assembly, a first rotating assembly, a second rotating assembly, and a third rotating assembly, wherein the hub assembly defines a rotational axis about which the first rotating assembly, the second rotating assembly, and the third rotating assembly are coaxially aligned and are capable of independent rotational movement independent of each other; a mechanical guide system supporting the hub assembly and constraining movement of the hub assembly so that the rotational axis of the hub assembly moves along a defined path that is in a transverse direction relative to the rotational axis; and a multi-bar linkage mechanism connecting to each of the first and third rotating assemblies and connecting the hub assembly to the mechanical guide system, wherein the multi-bar linkage mechanism causes the rotational axis of the hub assembly to translate along the defined path in response to relative rotation of the first rotating assembly and third rotating assembly with respect to each other.

Guided multi-bar linkage electric drive system

An electric motor including: a hub assembly defining a rotational axis; a magnetic rotor assembly; a first coil stator assembly; a second coil stator assembly; and a system of rotor bearings rotatably supporting each of the magnetic rotor assembly, the first coil stator assembly, and the second coil stator assembly on the hub assembly so that each of the magnetic rotor assembly, the first coil stator assembly, and the second coil stator assembly are rotatable about the rotational axis independently of each other.
