차량 경량화를 위한 토러스 축소와 고토크 토크컨버터 연구

Torque converter in automatic transmission transfer the engine power to transmission by ATF. Lock-up clutch of torque converter in automatic transmission has been recently designed with a significant purpose of achieving a more fuel economy. The newly developed round-high torus for short axial length achieves a high torque capacity and high efficiency. The new elliptical torus torque converter replaces the full torus about Φ205mm some of the Φ220 ~ Φ230mm converter that were previously used in similar applications. In a fuel-consumption conscious world, the minimum goal for the new elliptical torus converter must be to perform at least as well as its predecessors. To reduce development time and cost, many kinds of CAE technology is used. This paper describes for the new torus torque converter with lock-up operation.
