Abstract:
1. A multiple speed automatic transmission comprising, in combination, an input member, an output member, a first planetary gear assembly having a sun gear and carrier member, a second planetary gear assembly having a sun gear, a carrier member, and a ring gear; a third and a fourth planetary gear assembly each having a sun gear, a carrier member, and a ring gear, a first and a second means for transferring power from a first axis to at least one, parallel, spaced-apart axis, a first connecting member for connecting said carrier member of said first planetary gear assembly with said carrier member of said second planetary gear assembly, a second connecting member connected with said sun gear of said first planetary gear assembly, a third connecting member connected with said ring gear of said third planetary gear assembly a fourth connecting member for connecting said first power transferring means with said sun gear of said third planetary gear assembly, a fifth connecting member for connecting said sun gear of said second planetary gear assembly with said second power transferring means, a sixth connecting member for connecting said second power transferring means with said sun gear of said fourth planetary gear assembly, a seventh connecting member connected with said ring gear of said fourth planetary gear assembly, an eighth connecting member for connecting said first power transferring means with said ring gear of said second planetary gear assembly, said output member connected with said carrier members of said third planetary gear assembly and said fourth planetary gear assembly, a first torque transmitting mechanism selectively engageable to connect said input member to said first connecting member, a second torque transmitting mechanism selectively engageable to connect said input member to said second connecting member, a third torque transmitting mechanism selectively engageable to connect said input member to said fifth connecting member, a fourth torque transmitting mechanism selectively engageable to connect said input member to said eighth connecting member, a fifth torque transmitting mechanism selectively engageable to connect said third connecting member to said fourth connecting member, a sixth torque transmitting mechanism selectively engageable to connect said third connecting member to ground, a seventh torque transmitting mechanism selectively engageable to connect said seventh connecting member to said sixth connecting member, an eighth torque transmitting mechanism selectively engageable to connect said first connecting member to ground, a ninth torque transmitting mechanism selectively engageable to connect said seventh connecting member to ground.
