Toyota Motor Corporation has developed a new super-flat torque converter for the Flex Start System. It is installed in a new six-speed automatic transaxle (U660E) for front engine, front wheel drive vehicles. The Flex Start System is the first technology in the world that can start smoothly and reduce torque converter slipping loss by using a lock-up clutch at start. The newly developed super-flat torus achieves a high torque capacity and a maximum efficiency of 90%. Fuel economy is increased further by adding an efficient damper for low-speed lock-up in the free space provided by utilizing the super-flat torus. Toyota also developed a simple and super-flat structure at the one-way clutch (O.W.C.) area. This paper describes the structure, features, and performance of this new torque converter and the Flex Start System.
