Abstract

The clip retainer may include a first segment, a second segment extending substantially parallel to the first segment, and a bridge segment extending substantially perpendicularly between the first segment and the second segment. In various embodiments, the clip retainer is a unitary, monolithic structure.

First claim

1 . A clip retainer for a brake system comprising:
a first segment comprising a first middle portion and first circumferentially lateral portions; a second segment extending substantially parallel to the first segment and comprising a second middle portion and second circumferentially lateral portions; and a bridge segment extending substantially perpendicularly between only the first middle portion of the first segment and the second middle portion of the second segment; wherein gaps are defined between the first circumferentially lateral portions and the second circumferentially lateral portions such that the bridge segment extending between only the first middle portion and the second middle portion is the only structure of the clip retainer extending between the first segment and the second segment; wherein a middle radial dimension of the first middle portion and the second middle portion is comparatively less than a lateral radial dimension of the first circumferentially lateral portions and the second circumferentially lateral portions.

2 . The clip retainer of claim 1 , wherein the clip retainer is a unitary, monolithic structure.

3 - 4 . (canceled)

5 . The clip retainer of claim 4 , wherein the first circumferentially lateral portions and the second circumferentially lateral portions comprise an aperture for receiving a fastener.

6 . The clip retainer of claim 5 , wherein the first middle portion and the second middle portion each comprise a continuous outer surface.

7 . The clip retainer of claim 5 , wherein the middle radial dimension is comparatively less than a diameter of the aperture.

8 . The clip retainer of claim 3 , wherein a bridge radial dimension of the bridge segment is comparatively less than a middle radial dimension of the first middle portion and the second middle portion.

9 . The clip retainer of claim 8 , wherein a radially outward surface of the bridge segment is substantially flush with a radially outward edge of the first middle portion and the second middle portion.

10 . A brake system comprising:
a rotor comprising a rotor drive lug having a first axial side, a second axial side, and a radially outward surface, wherein an axially extending groove is defined in the radially outward surface; a clip disposed in a circumferential gap between the rotor drive lug and an adjacent rotor drive lug; a clip retainer for radially retaining the clip in the circumferential gap, the clip retainer comprising:
a first segment disposed on the first axial side of the rotor drive lug, wherein the first segment comprises a first middle portion and first circumferentially lateral portions;
a second segment disposed on the second axial side of the rotor drive lug, wherein the second segment comprises a second middle portion and second circumferentially lateral portions; and
a bridge segment extending through the axially extending groove defined on the radially outward surface of the rotor drive lug and extending axially between the first middle portion of the first segment and the second middle portion of the second segment, wherein a radially outward surface of the bridge segment is substantially flush with the radially outward surface of the rotor drive lug.

11 . The brake system of claim 10 , wherein the clip retainer is a unitary, monolithic structure.

12 . The brake system of claim 10 , wherein the radially outward surface of the rotor drive lug has a scalloped indentation, wherein the first middle portion and the second middle portion each comprises a radially outward edge that substantially follows the scalloped indentation, wherein the bridge segment extends axially across the scalloped indentation.

13 . The brake system of claim 12 , wherein the only structure of the clip retainer that extends across the radially outward surface of the rotor drive lug is the bridge segment disposed in the scalloped indentation.

14 . The brake system of claim 13 , wherein:
the rotor drive lug comprises two axially extending through-holes; the first circumferentially lateral portions and the second circumferentially lateral portions comprise apertures that align with the two axially extending through-holes; and the brake system further comprises two fasteners respectively extending through the two axially extending through-holes and through the apertures.

15 . The brake system of claim 14 , a middle radial dimension of the first middle portion and the second middle portion is less than a lateral radial dimension of the first circumferentially lateral portions and the second circumferentially lateral portions.

16 . The brake system of claim 15 , wherein the middle radial dimension is less than a diameter of a head of the two fasteners.

17 - 18 . (canceled)

19 . A method of installing a clip retainer of a brake system, the method comprising:
positioning a first segment and a second segment of the clip retainer on a first axial side and a second axial side, respectively, of a rotor drive lug of the brake system; positioning a bridge segment of the clip retainer within an axially extending groove formed in a radially outward surface of the rotor drive lug, wherein a radially outward surface of the bridge segment is substantially flush with the radially outward surface of the rotor drive lug; inserting two fasteners through apertures in circumferentially lateral portions of the first segment and the second segment; and inserting the two fasteners respectively through two axially extending through-holes of the rotor drive lug.

20 . The method of claim 19 , wherein:
the clip retainer is a unitary, monolithic structure; and the positioning the first segment and the second segment of the clip retainer on the first axial side and the second axial side, respectively of the rotor drive lug of the brake system occurs substantially simultaneously as the positioning the bridge segment of the clip retainer within the axially extending groove formed in the radially outward surface of the rotor drive lug.
