Abstract
A drive assembly for a torque converter includes an axially movable turbine defining a piston of a lockup clutch; and a damper assembly including a first component including a plurality of first ramps and a second component including a plurality of second ramps, the first ramps configured for interacting with the second ramps to generate an axial force on the turbine during a coast condition of the torque converter, the damper assembly being arranged and configured to limit the axial force to prevent the piston from self-locking during the coast condition.
Claims20
A torque converter drive assembly comprising:
- an axially movable turbine defining a piston of a lockup clutch;
- and
- a damper assembly including a first component including a plurality of first ramps and a second component including a plurality of second ramps, the first ramps contacting the second ramps to generate an axial force on the turbine during a coast condition of the torque converter, the damper assembly being arranged and configured to limit the axial force to prevent the piston from self-locking during the coast condition.
A method of forming a drive assembly for a torque converter comprising:
- connecting an axially movable turbine defining a piston of a lockup clutch to a damper assembly and aligning first ramps of the damper assembly with second ramps of the damper assembly, the first ramps contacting the second ramps to generate an axial force on the turbine during a coast condition of the torque converter;
- and
- configuring and arranging the damper assembly to limit the axial force to prevent the piston from self-locking during the coast condition.
