Guided multi-bar linkage electric drive system
First Claim
1. An electric drive system comprising:
- a rotary motor system comprising a hub assembly, a first rotating assembly, a second rotating assembly, and a third rotating assembly, wherein the hub assembly defines a rotational axis, wherein each of the first rotating assembly, the second rotating assembly, and the third rotating assembly is coaxially aligned with the rotational axis and is capable of rotational movement about the rotational axis, and wherein clockwise rotation of the first rotating assembly about the rotational axis causes counterclockwise rotation of the third rotating assembly about the rotational axis;
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.
