Abstract

A joint assembly includes a first member having splines formed therein. A second member includes splines formed thereon and is coupled to the first member. The splines of the first member engage the splines of the second member. An access window is formed on the first member. A ring retains the first member to the second member. A portion of the ring is accessible through the access window, where the ring can be manipulated to release the first member from the second member.

Claims (37)

1. A joint assembly comprising:

a first member having a first engagement means and an interior surface recess;

a second member having a second engagement means and an exterior surface recess, a portion of the second member disposed within the first member, the second engagement means engaging the first engagement means to provide a coupling of the second member to the first member;

a window formed within the first member where the portion of the second member is disposed within the first member;

a retaining means configured to retain the coupling of the second member to the first member, wherein distal ends of the retaining means are accessible through the window, wherein the distal ends of the retaining means extend in a direction radially outwardly into the window to a point at or radially inwardly from an outer wall of the first member, and wherein the retaining means is received partially into each of the interior surface recess of the first member and the exterior surface recess of the second member when the retaining means retains the coupling of the second member to the first member; and

a seal configured to cover the window, the seal coupled to the second member adjacent an end of the first member, the seal coupled to the first member adjacent the window, wherein a cylindrical portion of the seal covers the outer wall of the first member along at least a portion of a perimeter of the window, wherein the seal further includes a corrugated portion disposed adjacent the cylindrical portion, and wherein the corrugated portion is spaced radially from each of the first member and the second member.

2. The joint assembly of claim 1 , wherein the first member includes an open end and the first engagement means of the first member is formed within the open end.

3. The joint assembly of claim 2 , wherein the portion of the second member disposed within the first member is disposed within the open end and includes the second engagement means.

4. The joint assembly of claim 2 , wherein the window is continuous with the open end.

5. The joint assembly of claim 1 , wherein the first engagement means includes a first plurality of splines and the second engagement means includes a second plurality of splines.

6. The joint assembly of claim 1 , wherein the retaining means is configured as a retaining ring.

7. The joint assembly of claim 1 , further comprising a constant velocity joint coupled to one of the first member and the second member.

8. The joint assembly of claim 1 , wherein the cylindrical portion of the seal is disposed directly radially outwardly of the retaining means when the retaining means retains the coupling of the second member to the first member.

9. The joint assembly of claim 1 , wherein the window is continuous with an open end of the first member, and wherein the corrugated portion of the seal is disposed directly radially outwardly of the open end of the first member.

10. The joint assembly of claim 1 , wherein the cylindrical portion of the seal is disposed at an end of the seal.

11. A vehicle driveline comprising the joint assembly of claim 1 .

12. A vehicle comprising the joint assembly of claim 1 .

13. A joint assembly comprising:

a first member having an open end and a first plurality of splines formed within the open end;

a second member having a second plurality of splines formed thereon, a portion of the second member disposed within the first member, the second plurality of splines engaging the first plurality of splines to provide a coupling of the second member to the first member;

a window formed within the first member where the portion of the second member is disposed within the first member;

a retaining ring configured to retain the coupling of the second member to the first member, wherein distal ends of the retaining ring are accessible through the window, the first member including an interior surface annular recess and the second member including an exterior surface annular recess, wherein the retaining ring is received partially into each of the interior surface recess of the first member and the exterior surface recess of the second member when the retaining ring retains the coupling of the second member to the first member, and wherein the distal ends of the retaining ring extend in a direction radially outwardly into the window to a point at or radially inwardly from an outer wall of the first member; and

a seal configured to cover the window, the seal coupled to the second member adjacent the open end of the first member, the seal coupled to the first member adjacent the window, wherein a cylindrical portion of the seal covers the outer wall of the first member along at least a portion of a perimeter of the window, wherein the seal further includes a corrugated portion disposed adjacent the cylindrical portion, and wherein the corrugated portion is spaced radially from each of the first member and the second member.

14. The joint assembly of claim 13 , further comprising a constant velocity joint coupled to one of the first member and the second member.

15. A method of servicing a joint assembly comprising:

providing the joint assembly, the joint assembly including;

a first member having a first engagement means and an interior surface recess;

a second member having a second engagement means and an exterior surface recess, a portion of the second member disposed within the first member, the second engagement means engaging the first engagement means to provide a coupling of the second member to the first member;

a window formed within the first member where the portion of the second member is disposed within the first member;

a retaining means configured to retain the coupling of the second member to the first member, wherein distal ends of the retaining means are accessible through the window, wherein the distal ends of the retaining means extend in a direction radially outwardly into the window to a point at or radially inwardly from an outer wall of the first member, and wherein the retaining means is received partially into each of the interior surface recess of the first member and the exterior surface recess of the second member when the retaining means retains the coupling of the second member to the first member; and

a seal configured to cover the window, the seal coupled to the second member adjacent an end of the first member, the seal coupled to the first member adjacent the window, wherein a cylindrical portion of the seal covers the outer wall of the first member along at least a portion of a perimeter of the window, wherein the seal further includes a corrugated portion disposed adjacent the cylindrical portion, and wherein the corrugated portion is spaced radially from each of the first member and the second member;

uncovering the window from the cylindrical portion of the seal to provide access to the distal ends of the retaining means,

manipulating the distal ends of the retaining means through the window to release the coupling of the second member to the first member; and

separating the first member and the second member by disengaging the second engagement means from the first engagement means.

16. The method of servicing the joint assembly of claim 15 , wherein the joint assembly further comprises a constant velocity joint coupled to one of the first member and the second member.

17. The method of servicing the joint assembly of claim 15 , further comprising coupling the separated first member with another second member to form another joint assembly.

18. The method of servicing the joint assembly of claim 15 , further comprising coupling the separated second member with another first member to form another joint assembly.
