    摘要: A hydraulic control system for actuating a torque transmitting device in a transmission includes a sump for receiving a hydraulic fluid and a piezoelectric pump for pumping the hydraulic fluid from the sump to the torque transmitting device. A first fluid flow path communicates the hydraulic fluid from the sump to the piezoelectric pump and a second fluid flow path communicates the hydraulic fluid from the piezoelectric pump to the torque transmitting device. An exhaust means selectively communicates the hydraulic fluid from the torque transmitting device to the sump.

    摘要: A piezoelectric pump for pumping a fluid at a high flow rate includes a housing and an actuator located within the housing. An electric voltage applied to the actuator causes the actuator to apply a force to a first diaphragm that is proximate to the actuator. A piston assembly is located within the housing and is moveable between at least a first position and a second position. A first fluid chamber is defined by the housing, the first diaphragm, and the piston assembly. A coupling fluid is located within the first fluid chamber for coupling the first diaphragm to the piston assembly. A second fluid chamber is defined by the housing and the piston assembly. An inlet valve is in communication with the second fluid chamber and an outlet valve is in communication with the second fluid chamber.

    摘要: An auxiliary pump system for a hybrid powertrain includes a hydraulic accumulator, a hydraulic transformer, a plurality of control devices, a sump, and a plurality of fluid flow paths. The accumulator is charged by a high flow, high pressure hydraulic fluid by opening a first of the control devices and closing a second of the control devices. The accumulator is discharged by closing the first of the control devices and opening the second of the control devices. A high pressure, low flow hydraulic fluid is communicated from the accumulator to the hydraulic transformer. The hydraulic transformer converts the high pressure, low flow hydraulic fluid into a high flow, low pressure hydraulic fluid that is employed by systems within the hybrid powertrain.

    摘要: A hydraulic fluid circuit for a power transmission device includes a first hydraulic circuit segment fluidly decoupled from a second hydraulic circuit segment. A hydraulic pump includes a first fluidic pumping element and a second fluidic pumping element. The first fluidic pumping element fluidly communicates with the first hydraulic circuit segment. The second fluidic pumping element fluidly communicates with the second hydraulic circuit segment. The first fluidic pumping element is controllable to a first pump operating point to achieve a preferred high fluidic flow rate in the first hydraulic circuit segment. The second fluidic pumping element is controllable to a second pump operating point to achieve a preferred high fluidic pressure in the second hydraulic circuit segment.
