Abstract

A friction disk includes a friction disk core having a first surface with multiple channels extending radially across the first surface. The friction disk may further include a first wear liner having two wear liner segments each configured to be coupled to the first surface of the friction disk core to form an annular liner and each including a wear surface, a non-wear surface, and a rib extending from the non-wear surface and configured to be received by one of the multiple channels.

First claim

What is claimed is:

1. A friction disk comprising:
a friction disk core having a first surface and a second surface with multiple channels extending radially across the first surface and the second surface, the multiple channels including first channels extending across the first surface and second channels extending across the second surface, the first channels being axially misaligned with the second channels;
a first wear liner having an inner circumferential surface, an outer circumferential surface, and at least two wear liner segments each configured to be coupled to the first surface of the friction disk core to form an annular liner and each including a wear surface, a non-wear surface, and a rib extending from the non-wear surface from the inner circumferential surface to the outer circumferential surface, the rib defining at least one counterbore and configured to be received by one of the multiple channels; and
a plurality of fasteners each configured to extend through the at least one counterbore of the rib of a respective wear liner segment of the at least two wear liner segments to couple the respective wear liner segment to the friction disk core.

2. The friction disk of claim 1 , further comprising a second wear liner having identical features as the first wear liner and configured to be coupled to the second surface of the friction disk core.

3. The friction disk of claim 1 , wherein each of the multiple channels is defined by sidewalls that have a converging shape along a radially inward direction of the friction disk core.

4. The friction disk of claim 1 , wherein sidewalls of the rib are substantially perpendicular to a first non-wear surface.

5. The friction disk of claim 4 , wherein a circumferential dimension of the rib decreases from an outer diameter of the first wear liner towards an inner diameter of the first wear liner.

6. The friction disk of claim 1 , wherein the friction disk core includes a first material, and the first wear liner comprises a second material that is different from the first material.

7. The friction disk of claim 1 , wherein the friction disk core is at least one of a stator core or a rotor core.

8. The friction disk of claim 1 , wherein the first wear liner includes at least three wear liner segments.

9. The friction disk of claim 1 , wherein each of the multiple channels is defined by sidewalls that form an angle between 91 degrees and 155 degrees relative to the first surface of the friction disk core.

10. A friction disk comprising:
a friction disk core having a first surface and a second surface and including multiple channels extending radially across the first surface and the second surface, the multiple channels including first channels extending across the first surface and second channels extending across the second surface, the first channels being axially misaligned with the second channels;
a first wear liner configured to be coupled to the first surface of the friction disk core;
a second wear liner configured to be coupled to the second surface of the friction disk core; and
a plurality of fasteners,
wherein the first wear liner and the second wear liner each have an inner circumferential surface and an outer circumferential surface and include at least two wear liner segments that form an annular liner when coupled to the friction disk core, each of the two wear liner segments including a wear surface, a non-wear surface, and a rib extending from the non-wear surface from the inner circumferential surface to the outer circumferential surface, the rib defining at least one counterbore and configured to be received by one of the multiple channels, and
wherein each of one of the plurality of fasteners is configured to extend through the at least one counterbore of the rib of a respective wear liner segment of the at least two wear liner segments of the first wear liner and the second wear liner to couple the respective wear liner segment to the friction disk core.

11. The friction disk of claim 10 , wherein each of the multiple channels is defined by sidewalls that have a converging shape along a radially inward direction of the friction disk core.

12. The friction disk of claim 10 , wherein sidewalls of the rib are substantially perpendicular to a first non-wear surface.

13. The friction disk of claim 10 , wherein a circumferential dimension of the rib decreases from an outer diameter of the first wear liner towards an inner diameter of the first wear liner.

14. The friction disk of claim 10 , wherein the friction disk core includes a first material, and the first wear liner comprises a second material that is different from the first material.

15. The friction disk of claim 10 , wherein the friction disk core is a rotor core.

16. The friction disk of claim 10 , wherein the friction disk core is a stator core.

17. A multi-disk brake system comprising:
a plurality of rotors configured to rotate about an axis; and
a plurality of stators configured to remain stationary relative to the axis,
wherein at least one of the plurality of rotors or the plurality of stators includes:
a friction disk core having a first surface and a second surface with multiple channels extending radially across the first surface and the second surface, the multiple channels including first channels extending across the first surface and second channels extending across the second surface, the first channels being axially misaligned with the second channels,
a first wear liner having an inner circumferential surface, an outer circumferential surface, and at least two wear liner segments each configured to be coupled to the first surface of the friction disk core to form an annular liner and each including a wear surface, a non-wear surface, and a rib extending from the non-wear surface from the inner circumferential surface to the outer circumferential surface, the rib defining at least one counterbore and configured to be received by one of the multiple channels, and
a plurality of fasteners each configured to extend through the at least one counterbore of the rib of a respective wear liner segment of the at least two wear liner segments to couple the respective wear liner segment to the friction disk core.

18. The multi-disk brake system of claim 17 , further comprising a second wear liner having identical features as the first wear liner and configured to be coupled to the second surface of the friction disk core.

19. The multi-disk brake system of claim 17 , wherein a circumferential dimension of the rib decreases from an outer diameter of the first wear liner towards an inner diameter of the first wear liner.

20. The multi-disk brake system of claim 17 , wherein the friction disk core includes a first material, and the first wear liner comprises a second material that is different from the first material.
