Multiple-stage automatic transmission with kinematic coupling of wheel set elements to each other for eight forward gears and two reverse gears

摘要

The transmission has a main wheel set (HS) with an input element, which is connected to the drive shaft (AN) via an additional sixth selector element (F). Eight forward gears are selected in such a way, that for changing from one gear into the next highest or lowest, only one selector element is opened and a further element is closed. In a first forward gear, the first and fourth selector element (A,D) are closed, first and third (A,C) in the second gear, first and second element (A,B) in third gear, first and sixth element (A,F) in fourth gear, first and fifth element (A,E) in fifth gear, fifth and sixth element (E,F) in sixth gear, second and fifth element (B,E) in seventh gear, and third and fifth element (C,E) in eight gear. In a first reverse gear, the second and fourth element (B,D) are closed, and the fourth and sixth element (D,F) in a second reverse gear.
