摘要： A variable flow orifice for a hydraulic control system in a transmission includes a shape memory alloy that selectively increases and decreases the size of an orifice. The deformation of the shape memory alloy, and therefore the size of the orifice, is a function of the temperature of the transmission. During cold conditions the orifice size is increased and during normal operating conditions the size of the orifice is decreased.

摘要： A control system for controlling a dual clutch transmission having a synchronizer assembly includes a motor for selectively providing an output torque in a first and second to both of a first and a second output member. A one-way device is interconnected to the first output member and is operable to transmit the output torque in the first rotational direction. A pump is connected to the one-way device. A disconnect device is interconnected to the second output member. The torque disconnect device is operable to decouple the motor from a cam or a torque multiplication device. The cam includes at least one groove having a configuration corresponding to synchronizer assembly positions. A shift fork is disposed in the groove and is operable to translate the synchronizer assembly. Rotation of the cam translates the shift fork and the synchronizer assembly between at least a neutral position and an engaged position.

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 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.

摘要： An automatic transmission includes a control system for controlling a clutch of the transmission. The control system includes a first variable flow solenoid and a second variable flow solenoid, each in selective fluid communication with the clutch. The first variable force solenoid provides hydraulic fluid within a first pressure range of 0 and 1,000 kPa. The second variable force solenoid provides hydraulic fluid within a second pressure range of 0 and 2,000 kPa. A transmission controller sends an electrical signal having a current between the range of 0 and 1 amp to one of the first and second variable flow solenoids. The pressure output of each of the first and second variable force solenoids is a function of, within their respective first and second pressure ranges, the amplitude of the current of the electrical signal to provide two distinct power gains to the single clutch.

摘要： A system for controlling a transmission of a vehicle includes an engine control module that generates a command, while the vehicle is rolling in either a forward or reverse direction, to change a transmission of the vehicle from a reverse drive gear to a forward drive gear. The transmission includes a first clutch, a second clutch, a third clutch, and a fourth clutch. A transmission control module, in response to the command, maintains a first clutch in an engaged state, releases a second clutch and a fourth clutch, with the first clutch in the engaged state and the second clutch and the fourth clutch released, applies a third clutch with a synchronizer to engage the third clutch, and, after the third clutch is engaged, reapplies the fourth clutch to engage the fourth clutch.
