Abstract

The invention relates to a connecting arrangement between a shaft end and a joint part in which a collar on a connecting nut engages behind a another collar on the shaft end or on the joint part or on a clamping nut which clamps a bearing on the shaft, and one of the collars is formed by a oval ring received in a groove which facilitates disassembly of the connection formed by the connecting arrangement.

Claims

1. A connecting arrangement comprising:

an axially fixed shaft end, a constant velocity joint, and a connecting nut;

wherein a part of said constant velocity joint engages said shaft end in a rotationally fixed manner;

wherein said connecting nut for connecting said shaft end and said part of said constant velocity joint to one another has an internal thread;

wherein said connecting nut has at least one collar which, together with another collar forms a connection which is axially fixed in the screwing-on direction of said connecting nut, but which is releasable by an ovality provided on at least one of said collars;

wherein the collar having said ovality is formed by a ring introduced into a groove, said ring having oval regions projecting out of said groove.

2. The connecting arrangement as claimed in claim 1, wherein said internal thread of said connecting nut can be screwed at least indirectly onto said part of said constant velocity joint or onto said shaft end;

wherein said another collar is provided on said part of said constant velocity joint or said shaft end; and

wherein at least one component selected from the group consisting of said connecting nut, said shaft end, and said part of said constant velocity joint comprises said groove.

3. The connecting arrangement as claimed in claim 1, wherein one component selected from the group consisting of said part of said constant velocity joint and said shaft end has a second collar.

4. The connecting arrangement as claimed in claim 2 or 3, wherein said another collar and said second collar being provided together on one component selected from the group consisting of said part of said constant velocity joint and said shaft end;

wherein said another collar and said second collar being axially spaced apart; and

wherein said collar of said connecting nut is accommodated axially between said another collar and said second collar.

5. The connecting arrangement as claimed in claim 3, wherein said second collar being a spring ring which is provided in a groove.

6. The connecting arrangement as claimed in claim 5, wherein one component selected from the group consisting of said part of said constant velocity joint, said shaft end and said clamping nut has a second collar.

7. The connecting arrangement as claimed in claim 6, wherein said second collar being a spring ring which is provided in a groove.

8. The connecting arrangement as claimed in claim 1, further comprising:

a clamping nut provided on said shaft end;

wherein said internal thread of said connecting nut can be screwed at least indirectly onto a component selected from the group consisting of said part of said constant velocity joint, said shaft end, and said clamping nut;

wherein said another collar is provided on a component selected from the group consisting of said part of said constant velocity joint, said shaft end and said clamping nut; and

wherein at least one component selected from the group consisting of said connecting nut, said shaft end, said part of said constant velocity joint, and said clamping nut comprises said groove.

9. The connecting arrangement as claimed in claim 8 or 6, wherein said another collar and said second collar being provided together on one component selected from the group consisting of said part of said constant velocity joint, said shaft end, and said clamping nut;

wherein said another collar and said second collar being axially spaced apart; and

wherein said collar of said connecting nut is accommodated axially between said another collar and said second collar.

10. The connecting arrangement as claimed in claim 1, wherein said connecting nut is a locking nut.

11. The connecting arrangement as claimed in claim 1, wherein said ring is a spring ring.

12. The connecting arrangement as claimed in claim 1, wherein said part of said constant velocity joint is an inner part of said constant velocity joint and is provided with an external thread.
