摘要： A two-mode, compound-split, electra-mechanical transmission utilizes an input member for receiving power from an engine, and an output member for delivering power from the transmission. First and second motor/generators are operatively connected to an energy storage device through a control for interchanging electrical power among the storage device, the first motor/generator and the second motor/generator. The transmission employs three planetary gear sets. Each planetary gear arrangement utilizes first, second and third gear members. Moreover, one gear member of the first or second planetary gear set is operatively connected to the input member, and one gear member of the third planetary gear set is selectively connected to ground. A lock-up clutch selectively locks two of the planetary gear sets in a 1:1 ratio.

摘要： A hydraulic control system for a transmission includes a motor, a sump for storing a hydraulic fluid, and a dual element pump connected to the motor. The dual element pump has at least one input port connected to the sump, a first outlet port, and a second outlet port. The dual element pump provides a first volume of hydraulic fluid to the first outlet port and provides a second volume of hydraulic fluid to the second outlet port. The first volume is greater than the second volume. The first outlet port is connected to a diversion valve. The second outlet port is connected to a high pressure hydraulic circuit. The diversion valve is operable to transmit the hydraulic fluid from the first outlet port to a low pressure hydraulic circuit and the high pressure hydraulic circuit.

摘要： A vehicle powertrain for a hybrid vehicle includes an electronically variable transmission (EVT) with an input member to receive mechanical rotary power from the engine, an output member to provide mechanical rotary power to a vehicle powertrain to propel the vehicle, and an EVT gear train configured to selectively and operatively couple the input member to the output member. The EVT further includes first and second motor/generators driveably coupled to the gear train. A selectively engageable input brake mechanism is provided to create a reaction torque for the motor/generators thereby enabling the motor/generators to be used with additive power for electric propulsion or regenerative braking. The input brake improves electrical power to mechanical power conversion efficiency by reducing power circulation when the EVT is operated in electric drive, engine off mode.

First and second motor/generators are operatively connected to an energy storage device through a control for interchanging electrical power among the storage device.

摘要： An electrically variable transmission includes a power source, three differential gear sets, first and second motor/generators each connected to at least one of the gear sets, and torque-transmitting mechanisms. An input member transfers power from the power source through the differential gear sets to an output member. The torque-transmitting mechanisms are selectively engageable to provide an input-split first electrically variable mode having equal forward and reverse speed ratios for given input speeds and a compound, power-split second electrically variable mode. Torque provided from the power source is added to torque provided from the second motor generator in both forward and reverse electrically variable modes.
