Abstract

A shaft member includes a plurality of shaft splines and a shaft preloading portion. The assembly also includes a collar member adjustably coupled to the shaftmember and having a collar member groove and a preloading portion formed therein; a first member having a first member groove and a plurality of first member splines formed therein; and a retaining member selectively at least partially interposed within both the collar member groove and the first member groove for restraining axial movement between the shaft member and the collar member. At least a portion of the first member groove and at least a portion of the collar member groove are selectively aligned when the shaft member is at least partially interposed within the first member to permit the retaining member to be at least partially positioned within both the first member groove and the collar member groove.

Claims

1. A joint assembly comprising:

a shaft member rotationally coupled to a housing, the shaft member including a plurality of shaft splines and a shaft preloading portion;

a collar member adjustably coupled to the shaft member and having a collar member groove and a preloading portion formed therein;

an inner race of a constant velocity joint having an first member groove and a plurality of first member splines formed therein, wherein the constant velocity joint includes an outer race and a plurality of spherical rotational members interposed between and in contact with the outer race and the inner race; and

a retaining member selectively at least partially interposed within both the collar member groove and the first member groove for restraining axial movement between the shaft member and the collar member, wherein at least a portion of the first member groove and at least a portion of the collar member groove are selectively aligned when the shaft member is at least partially interposed within the inner race to permit the retaining member to be at least partially positioned within both the first member groove and the collar member groove and wherein at least a portion of the plurality of shaft splines are selectively positioned within an array of the spherical rotational members.

2. The assembly of claim 1, wherein the shaft member includes a plurality of gear teeth formed thereon for transmitting torque through a driveline.

3. The assembly of claim 1, wherein the shaft splines are dimensioned for an interference fit with the first member splines.

4. The assembly of claim 1, further comprising at least one bearing interposed between the housing and the shaft member, wherein the collar member may be moved relative to the shaft member to apply a preload to the at least one bearing.

5. The assembly of claim 1, wherein at least one of the first member groove and the collar member groove is a circumferential groove.

6. A joint assembly comprising:

a shaft member rotationally coupled to a housing, the shaft member including a plurality of shaft splines and a shaft preloading portion;

a collar member adjustably coupled to the shaft member and having an collar member groove and a preloading portion formed therein;

a constant velocity joint, including an inner race, an outer race and a plurality of spherical rotational members interposed between and in contact with the outer race and the inner race, wherein the inner race includes a inner race groove and a plurality of inner race splines formed therein, and wherein at least a portion of the plurality of shaft splines are selectively positioned within an array of the spherical rotational members; and

a retaining member selectively at least partially interposed within both the collar member groove and the inner race groove for restraining axial movement between the shaft member and the inner race.

7. The assembly of claim 6, wherein the shaft member includes a plurality of gear teeth formed thereon for transmitting torque through a driveline.

8. The assembly of claim 6, further comprising at least one bearing interposed between the housing and the shaft member, wherein the collar member may be moved relative to the shaft member to apply a preload to the at least one bearing.

9. The assembly of claim 8, wherein the shaft preloading portion is a preload biasing portion interposed between the bearing and a portion of the shaft member for, wherein the preload biasing portion is at least partially deformed when the bearing is preloaded.

10. The assembly of claim 6, wherein the shaft splines are dimensioned for an interference fit with the inner race splines.

11. A method of assembly for a driveline component, comprising:

interposing a shaft within at least one bearing;

positioning the shaft adjacent a collar member;

positioning a preload biasing portion between the bearing and a portion of the shaft;

preloading the bearing, wherein moving the collar member relative to the shaft, at least in part, increases the preload and at least partially deforms the preload biasing portion;

coupling a first portion of the collar member of a constant velocity joint to a portion of an inner race such that at least a portion of a collar member groove formed in the collar member and at least a portion of a race groove formed in the inner race are selectively at least partially aligned when the inner race is at least partially interposed within the first portion; and

inserting a retaining member at least partially within at least one of the collar member groove and the race groove.

12. The method of claim 11, further comprising applying a generally axial interference fit force to at least one of the preload member and the first portion to urge the shaft to move relative to the first portion, wherein the axial interference fit force will at least elastically deform at least a portion of one of the shaft and the first portion.

13. The method of claim 11, wherein coupling the first portion of the constant velocity joint includes inserting a portion of the inner race of the constant velocity joint into a portion of the collar member.

14. The method of claim 13, further comprising deflecting at least a portion of the retaining member radially as the inner race is inserted within the portion of the collar member.

15. The method of claim 11, further comprising interposing the inner race within the first portion of the constant velocity joint.

16. The method of claim 11, further comprising interposing a seal between a surface of the collar member and a surface of the inner race of the constant velocity joint.
