Abstract: A transmission includes a torque converter stator with controllable blade angle. A controller adjust the blades by commanding fluid pressures in hydraulic circuits routed to the stator hub. The controller also adjust the torque capacity of a torque converter bypass clutch by commanding fluid pressures in hydraulic circuits routed to apply and release chambers. Various schemes are presented to multiplex hydraulic circuits to serve multiple functions.

Abstract: A hydrokinetic torque converter includes an impeller, an axially displaceable turbine piston, and impeller and turbine-piston lockup clutch core plates. The impeller lockup clutch core plate is situated between the impeller shell and the turbine-piston shell, is connected to an impeller core ring, and has a first surface. The turbine-piston lockup clutch core plate is situated between the impeller shell and the turbine-piston shell, is connected to a turbine-piston core ring, and is axially displaceable with the turbine-piston to move a second surface of the turbine-piston lockup clutch core plate axially towards and away from the first surface for positioning the torque converter respectively into and out of a lockup mode in which the turbine-piston is mechanically interlocked to the impeller.

Abstract: A lockup clutch of torque converter comprising a front cover as an input part, an impeller linked to the outer circumference of the front cover, a second turbine disposed between the front cover and impeller in a position opposite to the impeller in the axial direction, a first turbine disposed between the impeller and the outer circumference of the second turbine, a stator disposed between the impeller and the inner circumference of the second turbine, a second turbine output part to which the inner circumference of the second turbine is linked, a power take-off support of the first turbine stretching outside the second turbine in the radial direction and between the second turbine and front cover, a first turbine output part to which the inner circumference of the support is linked, and a clutch disc disposed between the support and front cover, being linked to the inside of the front cover by friction, in which the output part of the clutch disc is formed by the folded part of the support.

Abstract: A fluid coupling transmission is adapted for interposition between the engine and the propulsion unit of a marine drive. The fluid coupling transmission provides variable speed operation in both forward and reverse. A fluid pump is drivingly connected to the engine crankshaft, and is adapted to drive a turbine. A series of variable position vanes are disposed between the fluid pump and turbine at the entrance of fluid into the pump, for controlling the power transfer therebetween by controlling the amount of fluid passing through the pump and acting on the turbine. A ring gear is connected to the turbine, and a sun gear is connected to the output shaft of the transmission. One or more planet gears are provided between the ring gear and the sun gear, and are rotatably mounted to a carrier member, which extends coaxially with respect to the output shaft.
