摘要： A normally-engaged clutch is provided having a friction-element with a first side and an opposing second side, a first plate configured for pressing against the friction-element on the first side, and a second plate configured for pressing against the friction-element on the second side. The clutch also includes a biasing device configured to apply a first force to the second plate for pressing the second plate against the friction-element to engage the clutch. Additionally, the clutch includes an apply piston for applying a second force to the first plate, and a release piston for applying a third force to the second plate. The clutch is disengaged when the second plate is pushed away from the friction-element by the third force in the absence of the second force, and is engaged when the first plate is pressed against the friction-element by the second force.

摘要： An actuator shifts a selectable one-way clutch (SOWC) between a plurality of operating modes. A first spring has a preload compression that is equivalent to a first start pressure. A second spring, disposed adjacent to the first spring, has a preload compression that is equivalent to a second start pressure. A plunger movably contacts the first spring and a slide plate movably extends from the plunger. The slide plate engages the SOWC such that the SOWC shifts between the operating modes in response to movement of the slide plate. The first spring is compressible from beyond the preload compression to a first stop position as the pressure is increased from the first start pressure to a first stop pressure. The second spring is compressible from beyond the respective preload compression to a second stop position as the pressure is increased from the second start pressure to a second stop pressure.

摘要： A torque converter for an automatic transmission includes a first fluid flow path for supplying a fluid to a pump cavity, a second fluid flow path for removing the fluid from the pump cavity, and a third fluid flow path for supplying a hydraulic signal to a lock-up clutch. The third fluid flow path is separate and distinct from the first fluid flow path and the second fluid flow path. A sleeve divides a stepped axial bore in the turbine output shaft into an inner stepped axial bore cavity, which is part of the third fluid flow path, and an outer stepped axial bore cavity, which is part of the first fluid flow path. The torque converter further includes an isolator assembly having a twenty degree rotational travel dampening distance.
