Multi-step automatic transmission for use in commercial motor vehicle, has carrier of one gearset and input shaft coupled to form one shaft, and another carrier of another gearset and output shaft coupled to form another shaft

摘要

The transmission has a carrier of a gearset (RS4) and an input shaft coupled to form a shaft (1), and another carrier of a gearset (RS3) and an output shaft coupled to form a shaft (2). A sun gear (SO1) of gearsets (RS1, RS4) couples for forming a shaft (3), and the carriers of gearsets (RS1, RS2) form shafts (4, 8). A ring gear (HO2) and a sun gear (SO2) of a gearset (RS3) couple for forming a shaft (7). A shifting element (A) e.g. friction-lock clutch, is located between the shaft (3) and a housing (GG), and another shifting element (B) is located between the shaft (4) and the housing.
