Abstract: A powertrain includes an output member, and first and second simple planetary gear sets. The planetary gear sets each have a first, a second, and a third member including a sun gear, carrier, and ring gear member. The drive unit includes a single electric machine operable as a motor and having a rotor connected to rotate in unison with and drive the sun gear member of the first planetary gear set. An interconnecting member connects the second member of the first planetary gear set to rotate in unison with the first member of the second planetary gear set. The third member of the first planetary gear set or the second member of the second planetary gear set is continuously grounded to the stationary member or operatively connected to be driven by an engine. The third member of the second planetary gear set is continuously operatively connected to the output member.

Abstract: A transmission for a vehicle is disclosed which includes a casing defining a first cavity and a second cavity inside the casing. A platform is at least partially disposed inside the casing to separate the first and second cavities. The platform defines a plurality of first apertures arranged together to define a first group. An interface assembly includes a first support and a plurality of first connectors attached to the first support to define a first bundle. The first support is selectively attached to the platform to position the first bundle relative to the platform such that each of the first connectors are disposed in respective ones of the first apertures of the first group. The first connectors are coupled to a power inverter module and a first motor/generator through the first apertures of the platform to electrically connect the power inverter module and the first motor/generator to each other.

Abstract: A ball cam actuated dog clutch assembly for a motor vehicle transmission includes a clutch sleeve having a plurality of gear teeth positioned at a first end and multiple ball bearings disposed at a second end. A clutch hub having multiple helical grooves is created in an outer facing wall. Each of the helical grooves receives a portion of one of the ball bearings. An actuator member acts to rotate the clutch hub. Rotation of the clutch hub causes axial translation of the clutch sleeve in a selected one of a first direction or an opposite second direction by translation of the ball bearings within the helical grooves.
