Abstract
Official abstract text for this publication.
A dual clutch transmission ( 500 ) having a plurality of forward gears and at least one reverse gear ( 582 ) where the first gear is operatively engaged by a one-way clutch ( 594 ). A pair of actuator control valves ( 270, 272 ) is employed to move actuators to engage selective ones of the forward gear sets. A multiplex valve ( 284 ) is disposed in fluid communication between the pair of actuator control valves ( 270, 272 ) and the actuators associated with the forward gears of the transmission and is adapted to selectively provide fluid communication to the actuators to thereby select the forward gear ratios. A manual valve ( 185 ) is operatively connected to the gear shift selector ( 187 ) to control the actuator associated with reverse gear ( 582 ).
First claim
Opening claim text (preview).
We claim: 1. A dual clutch transmission ( 500 ) having a plurality of forward gears and at least one reverse gear ( 582 ) for providing rotational output in two directions and at different gear ratios through a countershaft, said dual clutch transmission ( 500 ) comprising: a first gear set ( 570 ) operatively engaged with a first input shaft ( 520 ) by a one-way clutch ( 594 ) to provide a first gear; a plurality of other gear sets ( 572 , 574 , 576 , 578 ); first and seco…
