Abstract: A torque transmission device for a powertrain system includes a continuously variable unit (CVU) of a continuously variable transmission (CVT) arranged in parallel with a fixed-gear-ratio transmission. The fixed-gear-ratio transmission includes first and second planetary gear sets and a plurality of transmission clutches, wherein the first and second planetary gear sets are arranged to transfer torque between an input member and an output member in one of first and second fixed-gear-ratio modes by selectively activating the transmission clutches. The torque transmission device operates in a first fixed overdrive input/output speed ratio when the CVU input clutch is deactivated and a first set of two of the transmission clutches is activated. The torque transmission device operates in a second fixed overdrive input/output speed ratio when the CVU input clutch is deactivated and a second set of two of the transmission clutches is activated.

Abstract: A vehicle includes an engine, torque converter assembly, and transmission. The torque converter assembly includes a torque converter clutch (TCC). The transmission is connected to the engine via the torque converter assembly, and includes rotating and braking clutches, a pump, and a valve body assembly (VBA). The VBA includes Micro Electro Mechanical Systems (MEMS) pressure sensors and high-flow, hybrid MEMS flow control valves. Each MEMS pressure sensor and each MEMS control valve is in fluid communication with a corresponding one of the TCC, the rotating, and the braking clutches. The VBA includes first and second low-flow, fully MEMS valves which control line pressure to the VBA and fluid pressure to the TCC, respectively. The VBA delivers fluid pressure to the clutches, alone or in different combinations, to establish at least six different forward drive states of the transmission.

Abstract: A stator assembly for an electric machine includes stator teeth connected to a stator yoke to form a stator core. Adjacent teeth define a stator slot. Stator windings are disposed within the slot. A molding material fills the slot around the windings, providing a desired thermoelectrical performance level at different slot regions, including electrical insulation, thermal conductivity, and/or electrostatic shielding levels. A method insulates the stator assembly by inserting a molding tool(s) into the slot to define a void volume, filling the void volume with the dielectric molding material, and curing the dielectric molding material to form a slot liner layer adjacent to the tooth walls. A slot opening between adjacent teeth is filled with an electrically-conductive resin to form an electrostatic shielding layer. An electrical system includes an AC voltage bus connected to a power inverter module and to the electric machine having the above-described stator assembly.
