Abstract

A clutch disc assembly, comprising a friction plate, a damper fixedly secured to the friction plate, comprising an inwardly facing saline and a retainer plate, the retainer plate comprises a first radially inwardly facing surface and a second radially inwardly facing surface radially offset from the first radially inwardly facing surface, and a hub, the hub comprises a first radially outwardly facing surface having a circumferential groove, a second radially outwardly facing surface having an outer saline that meshes with the inwardly facing saline to non-rotatably connect the hub and the damper, and an internal saline surface.

First claim

What is claimed is:

1 . A clutch disc assembly, comprising:
a friction plate; a damper fixedly secured to the friction plate, comprising:
an inwardly facing saline; and,
a retainer plate, comprising:
a first radially inwardly facing surface; and,
a second radially inwardly facing surface radially offset from the first radially inwardly facing surface; and,

a hub comprising:
a first radially outwardly facing surface having a circumferential groove;
a second radially outwardly facing surface having an outer saline that meshes with the inwardly facing saline to non-rotatably connect the hub and the damper; and,
an internal saline surface.

2 . The clutch disc assembly as recited in claim 1 , further comprising a retainer ring, wherein the retainer ring is operatively arranged to secure within the circumferential groove.

3 . The clutch disc assembly as recited in claim 2 , wherein the friction plate, the damper, and the retainer plate are arranged concentrically about an axis of rotation.

4 . The clutch disc assembly as recited in claim 3 , wherein the hub is operatively arranged to be inserted in the damper in a first axial direction.

5 . The clutch disc assembly as recited in claim 4 , wherein the hub is operatively arranged to be removed from the damper in a second axial direction.

6 . The clutch disc assembly as recited in claim 5 , wherein the first radially inwardly facing surface comprises an internal saline operatively arranged to mesh with the outer saline to non-rotatably connect the hub to the damper.

7 . The clutch disc assembly as recited in claim 6 , wherein the hub, the damper, the retainer plate, and the friction plate are arranged concentrically about the axis of rotation.

8 . The clutch disc assembly as recited in claim 7 , wherein the second radially inwardly facing surface is operatively arranged to interfere with the outer saline such that, when the outer saline is engaged with the inwardly facing saline, the retainer plate prevents the hub from further movement in the first axial direction.

9 . The clutch disc assembly as recited in claim 8 , wherein the first radially outwardly facing surface is operatively arranged to be inserted through the second radially inwardly facing surface in the first axial direction such that, when the outer saline is engaged with the inwardly facing saline, the first radially outwardly facing surface extends beyond the second radially inwardly facing surface such that the circumferential groove is exposed.

10 . The clutch disc assembly as recited in claim 9 , wherein the retainer ring is operatively arranged to interfere with the second radially inwardly facing surface such that, when secured in the circumferential groove, the retainer ring prevents the hub from movement in the second axial direction.

11 . The clutch disc assembly as recited in claim 10 , wherein the damper comprises one or more damping springs.

12 . The clutch disc assembly as recited in claim 11 , wherein the internal saline surface comprises an internal saline geometry that is capable of meshing with an input shaft outer saline geometry.

13 . A clutch disc assembly, comprising:
a friction plate having a through-bore; a retainer plate comprising:
a first radially inwardly facing surface having an inwardly facing saline; and,
a second radially inwardly facing surface radially offset from the first radially inwardly facing surface; and,
a hub comprising:
a first radially outwardly facing surface having a circumferential groove;
a second radially outwardly facing surface having an outer saline that meshes with the inwardly facing saline to non-rotatably connect the hub and the damper; and,
an internal saline surface.

14 . The clutch disc assembly as recited in claim 13 , wherein the friction plate, the retainer plate, and the hub are arranged concentrically about an axis of rotation.

15 . The clutch disc assembly as recited in claim 14 , further comprising a retainer ring, wherein the retainer ring is operatively arranged to secure within the circumferential groove.

16 . The clutch disc assembly as recited in claim 15 , wherein the hub is operatively arranged to be inserted in the friction plate in a first axial direction.

17 . The clutch disc assembly as recited in claim 16 , wherein the hub is operatively arranged to be removed from the friction plate in a second axial direction.

18 . The clutch disc assembly as recited in claim 17 , wherein the second radially inwardly facing surface is operatively arranged to interfere with the outer saline such that, when the outer saline is engaged with the inwardly facing saline, the retainer plate prevents the hub from further movement in the first axial direction.

19 . The clutch disc assembly as recited in claim 18 , wherein the retainer ring is operatively arranged to interfere with the second radially inwardly facing surface such that, when secured in the circumferential groove, the retainer ring prevents the hub from movement in the second axial direction.

20 . A method of assembling a clutch disc assembly, the method comprising:
non-rotatably securing a retainer plate to a damper, wherein the damper has an internal saline and the retainer plate comprises a first radially inwardly facing surface and a second radially inwardly facing surface radially offset from the second radially inwardly facing surface, wherein the retainer plate is arranged such that the first radially inwardly facing surface is directed toward a front side of the damper; non-rotatably securing the damper to a friction plate, wherein the damper comprises an opening located on the front side of the damper such that the first radially inwardly facing surface of the retainer plate is exposed; inserting, in a first axial direction, a front end of a hub through the opening in the damper, wherein the front end of the hub comprises a circumferential groove; aligning, in a circumferential direction, a rear end of the hub with the internal saline of the damper, wherein the rear end of the hub comprises an outer saline that meshes with the internal saline of the damper; inserting, in the first axial direction, the rear end of the hub into the damper such that the outer saline engages with the internal saline and abuts against the retainer plate; and, affixing a retainer ring to the circumferential groove of the front end of the hub.
