Multiple speed transmission for use in passenger vehicle e.g. truck, has clutches and brake selectively engagable to establish forward speed ratio and reverse speed ratio between input member and output member

摘要

The transmission (10) has two clutches (70, 72) selectively engageable to interconnect an input member (12) and a sun gear member (22) of a planetary gear set (16) with a planet carrier member (28) of another planetary gear set (18). A brake (80) is selectively engageable to interconnect the planet carrier member (16) of a third planetary gear set (20) with a transmission housing (11). The clutches and the brake are selectively engagable to establish a forward speed ratio and a reverse speed ratio between the input member and an output member (14).
