    摘要: A sensor arrangement (46) for an automated transmission includes multiple axially parallel shift rails (4, 14, 24, 34) being axially displaceable by associated shift actuators (8, 18, 28, 38). The sensor arrangement (46) has multiple displacement sensors (48, 56, 64, 72) made up of a signal transmitter (50, 58, 66, 74) attached to a shift rail and a signal receiver (52, 60, 68, 76) fixedly arranged on a housing. The signal transmitters are in the form of a permanent magnet, and the signal receivers are in the form of a 3D Hall sensor. To detect an external magnetic interference field, which can corrupt the sensor signals from the displacement sensors (48, 56, 64, 72), the signal transmitters (50, 58, 66, 74) have identical axial alignments of their magnetic poles, and the signal receivers (52, 60, 68, 76) are in a common plane (80) that is horizontal in their installation position.

    摘要: A hydraulic control system adapted to carry out a speed change in case of rotating a wrapping transmission under the situation where solenoid valves for controlling a pressure in a hydraulic chamber cannot be energized.A pair of pulleys individually provided with hydraulic chambers to vary a width of a groove holding a belt. Those hydraulic chambers are connected with a hydraulic source through electrically controlled feeding control valves, and also connected with drain portions through electrically controlled relief control valves. The hydraulic control system includes a communicating passage connecting the hydraulic chambers, and the hydraulic control system disconnects the hydraulic chambers from the hydraulic source and the drain portions in case none of the feeding control valves and the relief control valves can be energized.

    摘要: There is provided a circuit configuration which does not require an additional fail-safe mechanism caused by the addition of a changeover valve in a hydraulic pressure control device for an automatic transmission having a function to directly supply a line pressure and hold (lock) an engaging pressure by combinations of electromagnetic valves and changeover valves.A changeover valve 20 is disposed between an output port 12 and a feedback port 13 of a linear solenoid valve 10 of the hydraulic pressure control device for an automatic transmission. The changeover valve 20 operates depending on at least an output pressure from the output port, and is switched between (1) a first state (control mode) in which a pressure Pc corresponding to an indicator current is outputted through the linear solenoid valve 10 by bringing the output port into communication with the feedback port, and (2) a second state (lock mode) in which a line pressure PL is outputted through the linear solenoid valve 10 by bringing the feedback port 13 into communication with a drain passage EX and discharging oil from the feedback port.

    摘要: A method of controlling driveshaft speed includes generating an overspeed protection action signal if an engine speed limit and a requested transmission gear ratio correspond to a driveshaft overspeed condition. An operating method for a machine includes disengaging a relatively higher transmission gear, and inhibiting re-engagement of the higher transmission gear responsive to an overspeed protection action signal. An electronic controller for the machine is configured to generate an overspeed protection action signal responsive to an engine speed limit and requested transmission gear ratio.

    摘要: In a transfer drive mode switching control system employing a shift actuator that switches from one of a plurality of drive mode positions of a transfer to the other, a drive mode position sensor is provided to detect the drive mode position switched by the shift actuator and to generate information regarding the drive mode position. A transfer control unit outputs a control command signal based on the drive mode position information to the shift actuator for controlling switching between the drive mode positions responsively to a driver-selected drive mode. The transfer control unit allows only a switching operation between predetermined two different drive mode positions corresponding to both ends of a working range of the shift actuator at which motion of the shift actuator is stopped mechanically, in presence of a failure in the drive mode position sensor.
