US Patent 10359099 Cycloidal differential

A cycloidal differential includes a driven body and a coupling ring supported for rotation within the driven body. The coupling ring defines a first eccentric race and a second eccentric race on opposing sides of the coupling ring. The cycloidal differential further includes first and second cycloidal drives. The first cycloidal drive includes a first roller disk received in the first eccentric race and a first output member operably coupled to the first roller disk and configured to couple with a half shaft. The second cycloidal drive includes a second roller disk received in the second eccentric race and a second output member operably coupled to the second roller disk and configured to couple with another half shaft.
