Abstract

A double clutch transmission comprising a wet dual clutch, a dual mass flywheel and a centrifugal force pendulum and an electric motor which is connected to the primary side of the dual mass flywheel.

Claims (26)

1. A double clutch transmission, comprising:

a drive sleeve;

a carrier connected with the drive sleeve so that rotation of the carrier is locked to rotation of the drive sleeve; and,

a plurality of clutch plates with respective radially outer portions engaged with the carrier;

a dual mass flywheel (DMF) including:

a primary side arranged to receive drive torque from an engine;

at least one spring in contact with the primary side;

a secondary-side flange engaged with the at least one spring and connected with the drive sleeve so that rotation of the secondary-side flange is locked to rotation of the drive sleeve; and,

a centrifugal force pendulum (CFP) directly connected to the secondary-side flange and located between the at least one spring and the drive sleeve; and,

an electric machine including a rotor:

directly connected to the primary side such that respective rotations of the rotor and the primary side are locked and such that the rotor and the primary side rotate at a same speed about an axis of rotation for the double clutch; or,

with a portion circumferentially aligned with and engaged with the at least one spring.

2. A double clutch transmission, comprising:

a drive sleeve;

a carrier connected with the drive sleeve so that rotation of the carrier is locked to rotation of the drive sleeve;

a plurality of clutch plates with respective radially outer portions engaged with the carrier;

a dual mass flywheel (DMF) including:

a primary side arranged to receive drive torque from an engine;

at least one spring in contact with the primary side;

a secondary-side flange engaged with the at least one spring and connected with the drive sleeve so that rotation of the secondary-side flange is locked to rotation of the drive sleeve; and,

a centrifugal force pendulum (CFP) located between the at least one spring and the drive sleeve and including:

first and second portions connected to the secondary-side flange and located on oppositely facing sides of the secondary-side flange; and,

an axis passing through the first and second portions and the secondary-side flange; and,

an electric machine including a rotor:

directly connected to the primary side such that respective rotations of the rotor and the primary side are locked and such that the rotor and the primary side rotate at a same speed about an axis of rotation for the double clutch; or,

with a portion circumferentially aligned with and engaged with the at least one spring, wherein the first and second portions of the CFP are at least partially rotatable about the axis passing through the secondary-side flange.
