摘要： A system and method for controlling the clutches in a vehicle powershift transmission. The control system includes a microprocessor which periodically executes an algorithm and which has a memory in which is stored a sequential set of time reference values and a sequential set of pressure values. The control system applies to each oncoming element a fill pressure pulse for fill periods which are unique for each element. The control system determines shift time values, subsequent to filling of the control elements, as a function of the fill period. The control system applies pressure signals to the control elements at times represented by the shift time values which are unique for each element. The control system determines, subsequent to a realignment time, realignment shift time values which are the same for all of the control elements. The control system also applies pressure signals to the control elements subsequent to the realignment time, at times determined as a function of the realignment shift time values.

摘要： The hydraulically operated brake and clutch elements (controlled by proportional control valves) of a vehicle powershift transmission have fill pressures which are calibrated by a method wherein the output shaft of the transmission is disconnected from the vehicle drive shaft so that the transmission output shaft is free to rotate and certain ones of the plurality of the control elements other than the control element being calibrated are fully pressurized in order to prevent rotation of a part of the control element being calibrated. The engine is run at a predetermined speed and the pressure applied to the control element being calibrated is gradually increased while engine speed is monitored. When the monitored engine speed changes by predetermined amount, a value is saved corresponding to the calibration pressure. The transmission is automatically shifted to neutral if vehicle motion is sensed. The volume of hydraulic fluid required to initially engage the control element may be calibrated in a similar manner.

摘要： A dual pump hydraulic system is provided for a vehicle driven by an internal combustion engine. The system includes a first circuit with a first high pressure pump supplying hydraulic fluid to the first subsystem at a higher pressure. The system also includes a second circuit with a second lower pressure pump supplying hydraulic fluid to the second subsystem at a second pressure. A first valve controls communication between the first pump and the second circuit. A second valve is operable to communicate the second pump with the first circuit when pressure in the first circuit is less than a second threshold pressure or when commanded by a control unit. A check valve prevents fluid flow from the first circuit back into to the second valve.

摘要： A single piston is used to activate the brake or clutch of a planetary transmission. The piston is spring-biased to engage one component and disengage the other, and hydraulically activated to disengage the first component and engage the second. An annular plate preferably is provided extending between the brake and the clutch, with the brake on one side of the plate and the clutch on the other. A spring then biases the annular plate towards one of the control components and away from the other, while a hydraulic cylinder is provided to press the plate away from the first component and towards the second.

摘要： An in-line transmission provides 26 useful speeds, including 19 forward speeds and 7 reverse speeds. The transmission includes a main planetary having three sets of planetary gears, as well as a separate hi-lo planetary. At least the first and second sets of planetary gears on the main planetary carrier are formed of double gears. Each side of the first set of double gears has its own ring gear which is independently brakable relative to the housing and its own sun gear. Drive from the input shaft to these two sun gears is provided along two main paths, one direct and the other through the hi-lo planetary. One side of the second set of double gears also has an independently brakable ring gear, as well as a sun gear connected to the output shaft. However, the other side of the second set of double gears meshes only with the third set of planetary gears, which preferably are single gears. The third set of planetary gears has its own independently brakable ring gear, and its own sun gear which is both brakable to the housing and clutchable to the main planetary carrier. The hi-lo planetary carrier preferably also uses double gears as planetary gears, with its ring gear meshing with one side of the double gears and its sun gear meshing with the other side. The hi-lo sun gear is selectively brakable to the housing or clutchable to the hi-lo planetary carrier.
