Coil spring tilger damper fixed to turbine

1. A torque converter, comprising:

a turbine with a turbine shell; and,

a damper assembly including:

an output flange;

a first cover plate;

a first drive plate fixedly secured to the turbine shell;

a first plurality of springs engaged with the first cover plate;

a second plurality of springs engaged with the first cover plate and the output flange and free of engagement with the first drive plate;

a third plurality of springs engaged with the first cover plate and the first drive plate and free of engagement with the output flange; and,

a single torque path from the turbine shell to the damper assembly, the single torque path formed by the first drive plate.

2. The torque converter of claim 1 wherein the second and third pluralities of springs are at a same radial distance from an axis of rotation for the torque converter.

3. The torque converter of claim 1 wherein the second and third pluralities of springs are circumferentially aligned.

4. The torque converter of claim 1 wherein the third plurality of springs is disposed radially outward from the second plurality of springs.

5. The torque converter of claim 1 wherein the third plurality of springs is disposed radially between the first and second pluralities of springs.

6. The torque converter of claim 1 further comprising:

a cover; and,

a lock up clutch engageable with the cover and directly engaged with the first plurality of springs.

7. The torque converter of claim 6 wherein:

the lock up clutch includes an axially displaceable piston plate and a second drive plate connected to the piston plate such that the second drive plate rotates when the piston plate rotates; and,

the second drive plate is in direct contact with the first plurality of springs.

8. The torque converter of claim 1 wherein a portion of the first drive plate is disposed axially between the flange and the first cover plate.

9. The torque converter of claim 1 wherein the first drive plate is rotatable relative to the flange and the first cover plate.

10. The torque converter of claim 1 wherein:

the damper assembly includes a second cover plate connected to the first cover plate by a plurality of fasteners; and,

rotation of the first drive plate is restricted by the plurality of fasteners.

11. The torque converter of claim 1 wherein:

the first cover plate includes a slot;

the first drive plate includes an axial protrusion disposed in the slot: and,

the rotation of the first drive plate is restricted by contact of the axial protrusion with respective ends of the slot.

12. A torque converter, comprising:

a cover;

a turbine with a turbine shell;

a lock up clutch including a piston plate, friction material, and a first drive plate; and,

a damper assembly including:

an output flange;

a cover plate;

a second drive plate fixedly secured to the turbine shell;

a first plurality of springs engaged with the cover plate and the second drive plate;

a second plurality of springs engaged with the cover plate and the output flange and circumferentially aligned with the first plurality of springs; and,

a third plurality of springs engaged with the cover plate and the first drive plate, wherein a portion of the second drive plate is disposed axially between the flange and the cover plate.

13. A torque converter, comprising:

a turbine with a turbine shell; and,

a damper assembly including:

an output flange;

a cover plate;

a first plurality of springs engaged the cover plate and located at a first radial distance from an axis of rotation for the torque converter;

a second plurality of springs engaged with the cover plate and the output flange and located at a second radial distance from an axis of rotation for the torque converter;

a third plurality of springs, separate from the first and second pluralities of springs and located at a third radial distance, less than the first radial distance and greater than the second radial distance, from an axis of rotation for the torque converter;

a single torque path from the turbine shell to the damper assembly;

a first torque path from the first plurality of springs to the output flange via the cover plate;

a second torque path from the third plurality of springs to the cover plate; and,

a solid torque path, including the single torque path, from the turbine shell to the third plurality of springs.

14. The torque converter of claim 13 wherein:

first torque transmitted along the first torque path urges the cover in a first rotational direction; and,

second torque transmitted along the second torque path urges the cover in a second rotational direction, opposite the first rotational direction.
