Development of Super Ultra Flat Torque Converter with Multi Plate Lock-up Clutch

Standard Details

Three-dimensional CFD was used to optimize the torus section and stator blade shape, and newly developed stator blades were also employed to develop the fluid flow channels for a thin type torque converter with a flattening ratio of 50%, while maintaining torque converter performance. A multi-plate lock-up clutch with heat-resistant performance approximately twice that of a conventional single-plate lock-up clutch has been positioned in the space created by the use of these new fluid flow channels. The developed Super Ultra Flat torque converter with multi-plate lock-up clutch enables all-area LC control without increasing the overall width compared to the previous torque converter, and can be fitted in an FF vehicle. As a result, in real-world driving, the new system increased fuel efficiency by approximately 3% in US06 mode, and enabled a more direct driving feeling by shortening the time from 0 to 100 km/h at 100% throttle acceleration by 0.2 s, etc.
