1. An adaptive stabilizer bar comprising:
a divided torsion bar having mutually facing ends;
a cycloidal drive disposed between the mutually facing ends of the divided torsion bar, wherein the cycloidal drive includes an electric motor coupled to a cycloidal gear assembly to rotate a first portion of the divided torsion bar relative to a second portion of the divided torsion bar, wherein the cycloidal gear assembly includes:
a cam drive gear intermeshed with an input gear that is rotatable by the electric motor,
a cam shaft that rotates in unison with the cam drive gear,
first and second cycloidal gears that oscillate by operation of the cam shaft, and
a ring gear surrounding at least one of the first and second cycloidal gears,
wherein the cam shaft includes a first cam for engaging the first cycloidal gear and includes a second cam for engaging the second cycloidal gear, the second cam being axially offset from the first cam.
