Nine speed automatic transmission
摘要:
The present invention provides a nine forward speed automatic transmission for a motor vehicle which includes four planetary gear sets, a plurality of friction and synchronizer clutches and two chain drive assemblies. The transmission is arranged along two parallel axes of rotation: a first axis defined by the input shaft and a second axis defined by the output shaft. The chain drive assemblies transfer power between sprockets disposed on the two axes. Various combinations of clutches may be engaged to provide nine forward speed ratios and five reverse speed ratios.
