CFT30-用于6缸FWD车辆的链式CVT

CFT30是第一种将链传动应用于前置（横置）前驱、并配备有提高起步性能的变矩器的CVT。变速器能够传递现代6缸发动机310Nm的转矩。它采用全电子控制，比目前常用的4速自动变速器及刚开发出来的6速自动变速器性能更好、油耗更低。完美的换档感觉提高了驾驶舒适性。本文介绍了变速器系统、设计和主要部件。对CFT30如何解决燃油经济性、性能和舒适性作了详细的解释。同时给出了重要的部件试验和车辆试验结果。

CFT30-A Chain Driven CVT for FWD 6 Cylinder Applications

The CFT30 is the first CVT that uses a chain drive in a front-transversal installation and combines this with a torque converter for better launch performance. The transmission is capable of handling the 310 Nm engine torque of modern 6-cylinder engines. It employs fully electronic controls and achieves better performance and fuel economy results than today＇s 4-speed automatic transmissions and even newly developed 6-speeds in the same vehicle. Perfect shift-feel is increasing the driving comfort. The paper describes transmission system, design and main components. The contribution of CFT30 specific design solutions to fuel economy, performance and comfort are explained. Most important test results of component and vehicle testing are shown.
