    摘要： A hydraulic fluid supply system includes an active pressure regulator or feed limit valve with a flow cut-off which may be used with dual clutch transmission hydraulic control systems. The supply system includes a pump, a filter, pressure relief and filter bypass valves, an accumulator, a system pressure sensor and the active feed limit valve. The active feed limit and flow cut-off valve includes an on-off solenoid valve and a spool or logic valve having an inlet port, an outlet port, a control port, a feedback port and an exhaust port. The inlet port is supplied with pressurized hydraulic fluid and the control port is supplied with hydraulic fluid from the solenoid control valve when it is energized. A valve spool having a pair of spaced-apart lands is biased toward the control port. One side of a check valve is in fluid communication with the feedback port. The outlet port provides controlled pressure and flow of hydraulic fluid to the hydraulic control system and is in fluid communication with the other side of the check valve.

    摘要： A hydraulic control system for a dual clutch transmission includes a plurality of solenoids and valves in fluid communication with a plurality of clutch actuators and with a plurality of synchronizer actuators. The clutch actuators are operable to actuate a plurality of torque transmitting devices and the synchronizer actuators are operable to actuate a plurality of synchronizer assemblies. Selective activation of combinations of the solenoids allows for a pressurized fluid to flow through the valves to activate at least one of the clutch actuators and synchronizer actuators in order to shift the transmission into a desired gear ratio. A range selection valve is operable to place the transmission in Park and out-of-Park modes of operation.

    摘要： A compact fluid accumulator both stores a relatively large amount of fluid and provides good fluid pressure stability. The accumulator includes a piston slidably disposed in a cylinder having a fluid inlet/outlet at one end which communicates with a first chamber and one face of the piston. Engaging the opposite face of the piston, and disposed in a second chamber, is a compression spring. The second chamber is filled with a gas which is at atmospheric pressure when the accumulator is relaxed. When pressurized hydraulic fluid fills the first chamber, the piston moves against the pressure of the spring and gas in the second chamber. The present invention thus provides an accumulator having the relatively small size of a gas filled accumulator without the leakage problem of a super-atmospheric gas charge—the extra force being provided by the compression spring.

    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.
