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. An output control mechanism, including a brake band and a plate clutch mechanism, is selectively engagable with the carrier member so as to control the direction of rotation of the transmission output shaft.
