Abstract:
A transmission includes a first gear set with a first sun gear member rotatable about a first axis of rotation, a second sun gear member rotatable about the first axis of rotation, a carrier member, and a ring gear member radially outward of and concentric with the first sun gear member. A first annular gear meshes with the first sun gear member, and a second annular gear meshes with the first annular gear, the second sun gear member, and with the ring gear member. The first annular gear is rotatable about a second axis of rotation and the second annular gear is rotatable about a third axis or rotation.
