Drive axle assembly having a ring gear adjustably secured to a differential case
First Claim
1. A drive axle assembly comprising:
- a differential case;
a ring gear non-rotatably and longitudinally slidably mounted onto said differential casean adjustment collar threadingly engaging said differential case adjacent said ring gear adapted to selectively position said ring gear and said adjustment collar in relation to said differential case, anda fastening device for locking said threaded adjustment collar to said ring gear.

Abstract
An adjustment collar for a positioning a ring gear to a differential case. The ring gear is splined to the differential case so as to allow axial displacement. The adjustment collar is threaded onto the differential case adjacent to the ring gear. The adjustment collar is rotated to axially position the adjustment collar, and consequently the ring gear relative to the differential case and axle assembly. The adjustment collar and ring gear are bolted to one another to prevent relative rotation there between. Because the ring gear is splined to the differential case, relative rotation between the ring gear and differential case, and consequently the adjustment collar and the differential case, is prevented. Because the ring gear and adjustment collar are locked to one another, the two components are thus prevented from both axial and rotational movement. The arrangement provides the ability to selectively position the ring gear axially after the differential assembly is installed in the housing, thus eliminating the need for shims or other cumbersome expensive adjusting devices. The overall axle assembly is then assembled with tighter tolerance.

5. An axle assembly comprising:
-
a differential case having an axis of rotation; a ring gear non rotatably mounted to said differential case concentric with said axis of rotation; and an adjustment means for selectively positioning said ring gear relative to said differential case in a direction parallel to said axis of rotation.

6. An axle assembly comprising:
-
a differential case having an axis of rotation; a ring gear non rotatably mounted to said differential case concentric with said axis of rotation; and an adjustment means for selectively positioning said ring gear in a direction parallel to said axis of rotation, wherein said adjustment means includes; an adjustment collar threadingly engaging said differential case; said ring gear is splined to said differential case to allow axial displacement and prevent relative rotation there between;
whereby rotation of said adjustment collar facilitates selective axial positioning of said adjustment collar and said ring gear with respect to said differential case, andsaid adjustment collar and said ring gear are bolted together to prevent relative rotation there between, thereby fixing said ring gear in both rotational and axial positions relative to said differential case.

7. A method of positioning a ring gear relative to a differential case in an axle assembly, said method comprising the steps of:
-
mounting said ring gear to said differential case to allow axial translation of said ring gear relative to said differential case and preventing relative rotation there between; threadingly mounting an adjustment collar to said differential case adjacent said ring gear, rotating said adjustment collar to a specific position to thereby position said ring gear in a desired location in relation to said differential case; securing said adjustment collar to said ring gear to prevent relative rotation there between. - View Dependent Claims (8)
