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.

The outputs of the check valves are provided to those hydraulically operated torque transmitting devices associated with first gear. The solenoid pump is activated when the transmission is in gear and the engine is stopped to maintain hydraulic pressure in those actuators associated with first gear in order that a first gear vehicle launch may be quickly and smoothly achieved when the engine is restarted. A second, similar embodiment provides hydraulic fluid to actuators associated with reverse gear. A third embodiment includes a solenoid pump and a latching solenoid valve both communicating with a hydraulic supply between a variable output solenoid valve and a hydraulic actuator in an automatic transmission which maintains clutch pressure by compensating for leaks in the hydraulic components. In a fourth embodiment, a solenoid pump provides pressurized hydraulic fluid to the exhaust backfill circuits of one or more hydraulic operators in an automatic transmission.

摘要： A multiplexed electromechanical shift mechanism includes a single linear actuator with multiple independently selectable linkages actuating a clutch and multiple gears for use in motor vehicle transmissions such as a dual clutch transmission. The linear actuator may be a ball screw, a planetary roller screw or hydraulic or pneumatic operator capable of controlling bi-directional linear motion of an output member. A plurality of linear clutches selectively couple the output member to one of a plurality of linkages adapted to transfer the bi-directional motion of the output member. One of the linkages is coupled to and engages an input (main) clutch of the transmission and the remaining linkages are coupled to and bi-directionally translate shift forks and synchronizer clutches which achieve gear selection and engagement.
