Abstract

A transmission assembly for operably coupling an input member to an output member includes a first cycloidal gear stage having a first gear ratio and a second cycloidal gear stage having a second gear ratio different than the first gear ratio. The transmission assembly also includes a shifting mechanism for selectively driving the output member with one of the first cycloidal gear stage and the second cycloidal gear stage.
