摘要： An assembly for actuating a synchronizer includes a shift fork, a shift rail, and a permanent magnet connected to the shift rail. A first control coil is disposed in proximity to the permanent magnet. The first control coil is operable to produce a magnetomotive force on the permanent magnet in a first direction when a current is applied to the first control coil. A second control coil is disposed in proximity to the permanent magnet. The second control coil is operable to produce a magnetomotive force on the permanent magnet in a second direction when a current is applied to the second control coil. The permanent magnet is moved to a first position when the current is applied to the first control coil and the permanent magnet is moved to a second position when the current is applied to the second control coil. Movement of the magnet in turn moves the synchronizer between engaged positions.

摘要： A control system for a dual clutch transmission (DCT) of a vehicle comprises a difference module, a summer module, and a position control module. The difference module determines a difference between a desired position for a gear actuator and a measurement of a current position of the gear actuator. The summer module determines a sum of a derivative of the difference and a product of the difference and a predetermined gain. The position control module controls the current position of the gear actuator based on the sum. The current position of the gear actuator controls a position of a gear synchronizer that slides along an output shaft of the DCT. The position of the gear synchronizer controls coupling of a gear ratio with the output shaft.

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.
