Patent ID: 7384361

Claim:
A planetary gear type multistage transmission for vehicles, comprising: a first transmission portion and a second transmission portion, wherein the transmission is constructed to transmit rotations of an input rotating member positioned at a driving-force source side to be rotatable around a first axial center, to the second transmission portion positioned on a second axial center parallel to the first axial center via the first transmission portion, and to output the rotations of the input rotating member from an output rotating member rotating around the second axial center, wherein the first transmission portion transmits rotations of the input rotating member to the second transmission portion via a first intermediate output path and a second intermediate output path, wherein the second transmission portion is provided with three planetary gear sets of a first planetary gear set, a second planetary gear set and a third planetary gear set, which are disposed one after another to be concentric with the second axial center, five rotary elements are composed by partially connecting sun gears, carriers and ring gears of the three planetary gear sets, at least four rotary elements of the five rotary elements are selectively connected to any one of a first driven member composing the first intermediate output path at a second axial center side, a second driven member composing the second intermediate output path at the second axial center side, the output rotating member and a non-rotating member via clutches and brakes, wherein seven forward speed transmission stages are established by selectively switching engaging state of the clutches and the brakes and disengaging state of the clutches and the brakes, wherein a rotational speed of the rotation transmitted by the second intermediate output path is lower than a rotational speed of the rotation transmitted by the first intermediate output path, wherein a first rotary element of the five rotary elements is selectively connected to the second driven member via a second clutch and is selectively connected to the non-rotating member via a first brake, wherein a second rotary element of the five rotary elements is selectively connected to the first driven member via a third clutch and is selectively connected to the non-rotating member via a second brake, wherein a third rotary element of the five rotary elements is selectively connected to the first driven member via a fourth clutch, wherein a fourth rotary element of the five rotary elements is connected to the output rotating member, and wherein a fifth rotary element of the five rotary elements is selectively connected to the second driven member via a first clutch.
