摘要： PROBLEM TO BE SOLVED: To selectively operate a transmission at a first operating configuration using an effective gear ratio having a first prescribed number, and a second operating configuration using an effective gear ratio having a second prescribed number by providing a programmable controller for selectively controlling the transmission. SOLUTION: A programmable electronic transmission control unit 32 is disposed, and which is provided with a memory for storing at least one pair of shift operation characteristics. An operating configuration of a transmission 26 is restricted by the operation characteristic, which contains one or more of an effective gear ratio having the maximum numbers, a pair of effective gear ratios, and a pair of operating gear ratios selected from a plurality of effective gear ratios. Accordingly, it is possible to program the transmission control unit 32 so as to change one or more operation characteristic(s) of operation characteristics so as to form a second operating configuration of the transmission 26.

摘要： A lubrication system for an automatic transmission clutch assembly having a drive and driven rotary member (32, 36) rotatable by a common axis with a clutch element (38, 40) therebetween for connecting and disconnecting the members. The drive member (32) has an internal passageway (62) formed therein for feeding the lubricant to the clutch member. The passageway has a section which is radially spaced from the axis of rotation and has a seat (72) formed therein for cooperating with a rotationally speed sensitive valve (74) oriented in the first passageway. Below a first rotational speed, the lubricant pressure maintains the valve against the seat restricting the flow of lubricant to the clutch element. When the driven member is rotated above the first rotational speed. Centrifugal force biases the valve off the seat, allowing lubricant to be supplied to the clutch element. Preferably, a second lubrication passageway (76) is provided having a seat in an internal valve which selectively supplies a lubricant to the clutch element at a second higher rotational speed. In order to further reduce disengaged clutch drag at idle, a speed sensitive piston retract spring (58) is provided to increase piston travel at low engine speeds while maintaining minimum travel at off idle operation.

摘要： A torque converter lock-up and disconnect clutch assembly (10) for an automatic mechanical transmission system (12) of the type comprising a fluid torque converter (20) drivingly interposed a drive engine (16) and a mechanical change gear transmission (14), preferably of the type utilizing a power synchronizing device (30), is provided. The torque converter lock-up and disconnect clutch structure includes an independently engagable and disengagable torque converter disconnect friction clutch (24) and torque converter lock-up friction clutch (26). A first connecting member (74) is fixed for rotation with the transmission input shaft (72) and a second connecting member (79) is rotationally fixed to the torque converter turbine (60). A first friction clutch (24) selectively engages and disengages the first and second connecting members and a second friction clutch (26) selectively engages and disengages the second connecting member and the engine driven shroud (58).

摘要： Disclosed is an automatic control system for a powershift, preselect transmission (10) including a plurality of power paths (36, 38) alternately connectable between input (12) and output (20) shafts by first engaging selected ones of synchronizer clutches (42, 74, 84) associated with each of a plurality speed ratio gears (44,46,76,78,80) in each path and then alternately engaging a powershift clutch (48, 82) associated with each path. The control system includes a hydraulic logic system (118) which may be electronic and a hydraulic and shift valve system which may be electrically controlled should the logic be electronic. The control system preselects ratio gears in a nondriving path and then alternately engages the powershift clutches to switch driving connections from one path to the other. The logic system includes an improved reverse sequence valve (132) and improved shift valves (124, 126, 128). The shift valve system Includes the feature of trimmer valves (64, 70, 72, 74) to control the engagement rate of the synchronizer clutches and combination trimmer valves (360, 366) to control the engagement rate of the powershift clutches.The logic system further includes the feature of preselecting reverse when a manual shift valve (700) is in the neutral position.
