Nine speed transmission for transmitting torque from input shaft to output shaft, has transmitting mechanisms or clutches selectively engageable to interconnect one of gears and stationary element or transmission housing

摘要

The transmission (10) has a set of interconnecting members (42-48) continuously interconnecting a sun gear (14C), a planet gear (14D) and a ring gear (14A) of multiple planetary gear sets. Six torque transmitting mechanisms or clutches (26-36) are selectively engageable to interconnect one of the gears and a stationary element or transmission housing (50), where the mechanisms are selectively engageable in combinations of three to establish nine forward speed ratios and one reverse speed ratio between input and output shafts (12, 22).
