摘要： 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.

摘要： 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.

Springs of the first spring set are deflected by axial rotation between the first and second cage portions when the torque converter clutch is engaged. A second spring cage has a first cage section connected to the hydraulically actuated clutch and a second cage section connected to a torque converter turbine. A second spring set has second springs having a spring constant different than the first spring set. The second spring set springs are deflected by axial rotation between the first and second cage sections.
