Abstract

An outer joint member for a joint assembly configured to receive an inner joint includes a wall forming a hollow chamber having a closed end and an open end. A plurality of restrictors are coupled to the hollow chamber each having a portion thereof extending outwardly from the inner surface of the wall of the hollow chamber. The plurality of restrictors extending from the inner surface of the wall proximate the open end of the hollow chamber.

First claim

What is claimed is:

1. An outer joint member for a joint assembly configured to receive an inner joint member comprising:
a wall forming a hollow chamber having a closed end and an open end; and
a plurality of restrictors coupled to the wall, each of the plurality of restrictors having a portion thereof extending outwardly from an inner surface of the wall of the hollow chamber, the plurality of restrictors extending radially inwardly from the inner surface of the wall adjacent the open end of the hollow chamber, wherein each of the plurality of restrictors is a pop-rivet, a stud, a pin, a screw, a bolt, or a rod.

2. The outer joint member of claim 1 , wherein each of the plurality of restrictors extends through the wall of the hollow chamber.

3. The outer joint member of claim 1 , wherein the outer joint member has a substantially tri-lobal cross-sectional shape.

4. The outer joint member of claim 1 , further comprising an annular array of recesses formed in the wall, wherein each of the recesses includes a pair of tracks formed therein, wherein the plurality of restrictors are coupled to the outer joint member at each of the pair of tracks.

5. A joint assembly comprising:
a hollow outer joint member including a wall forming an open end and a closed end;
an inner joint member having a plurality of roller assemblies coupled thereto, the plurality of roller assemblies received in the outer joint member; and
a restrictor configured to engage at least one of the plurality of roller assemblies to militate against decoupling of the inner joint member with respect to the outer joint member, wherein the restrictor is a pop-rivet, a stud, a pin, a screw, a bolt, or a rod.

6. The joint assembly of claim 5 , wherein the restrictor extends through the wall of the outer joint member.

7. A joint assembly comprising:
a hollow outer joint member including a wall forming an open end and a closed end, the hollow outer joint member having an annular array of recesses formed therein, each of the annular array of recesses having a pair of longitudinally extending opposing tracks;
an inner joint member having a plurality of roller assemblies coupled thereto, the plurality of roller assemblies received in the pair of tracks and movable along the pair of tracks with respect to an axial direction of the outer joint member; and
a restrictor coupled to the wall of the outer joint member, the restrictor configured to engage with at least one of the plurality of roller assemblies to militate against decoupling of the inner joint member with respect to the outer joint member, wherein the restrictor is a pop-rivet, a stud, a pin, a screw, a bolt, or a rod.

8. The joint assembly of claim 7 , wherein the outer joint member has a tri-lobal cross-sectional shape.
