摘要： A high efficiency hydraulic control system for a dual clutch transmission includes one or two hydraulic pumps. In a first embodiment, a single hydraulic pump provides pressurized hydraulic fluid to a pressure control valve, filter and accumulator. A first pair of variable feed solenoid valves independently and mutually exclusively provide hydraulic fluid to a respective pair of main or input clutch actuators. A second pair of variable feed solenoid valves provide hydraulic fluid to a pair of inlet ports of a first spool or logic valve. The position of the spool of the first logic valve is controlled by an on-off solenoid valve. A first pair of outlet ports of the first logic valve selectively provide hydraulic fluid to a first three area piston which selects two gear or speed ratios, for example, reverse and third gear. A second pair of outlet ports of the first logic valve selectively provide hydraulic fluid to a pair of inlet ports of a second spool or logic valve. The position of the spool of the second logic valve is controlled by hydraulic fluid from the input clutch circuits. A first pair of ports of the second logic valve selectively provide hydraulic fluid to a second three area piston which selects two other gear or speed ratios, for example, first and fifth gears and a second pair of ports of the second logic valve selectively provide hydraulic fluid to a third three area piston which selects two additional gear or speed ratios, for example, second and fourth gears.

摘要： A hydraulic control system for a dual clutch transmission includes a source of pressurized hydraulic fluid, first and second actuator control devices in downstream fluid communication with the source of pressurized hydraulic fluid, and first and second clutch control devices in downstream fluid communication with the source of pressurized hydraulic fluid. A first valve is in downstream fluid communication with the first and second actuator control devices. A second valve is in downstream fluid communication with the first valve, the first clutch control device and the second clutch control device, and the second valve is moveable between two positions by the first and second clutch control devices. Selective activation of combinations of the control devices allows for a pressurized fluid to engage the dual clutch and an actuator in order to shift the transmission into a desired gear ratio.

摘要： A hydraulic control system for a dual clutch transmission includes a plurality of pressure and flow control devices and logic valve assemblies 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 pressure control solenoids and the flow control solenoids allows for a pressurized fluid to activate at least one of the clutch actuators and synchronizer actuators in order to shift the transmission into a desired gear ratio.

摘要： A system for providing a constant flow of cooled hydraulic fluid to a dual clutch assembly of a transmission of a motor vehicle includes a hydraulic fluid cooler, a pressure control valve and a logic valve. The system is also capable of providing additional hydraulic fluid to the dual clutch assembly. The hydraulic fluid cooler provides hydraulic fluid to each clutch of a dual clutch assembly and to a logic valve.
