Abstract

Methods and systems are provided for a clutch assembly. The clutch assembly includes, in one example, a sleeve that is configured to at least partially circumferentially surrounds a hub a detent assembly positioned in the hub and configured to hold the sleeve and the hub in a defined axial position. The detent assembly includes an opening with a ball and a spring positioned therein and a retaining device that maintains the spring and the ball in the opening, where the ball mates with a detent in the sleeve.

Claims (26)

1. A clutch assembly, comprising:

a sleeve that is configured to at least partially circumferentially surround a hub; and

a detent assembly positioned in the hub, configured to hold the sleeve and the hub in a defined axial position, and including:

a first opening with a ball and a spring positioned therein; and

at least one of a circlip and a bushing that maintains the spring and the ball in the first opening;

wherein the ball mates with a detent in the sleeve.

2. The clutch assembly of claim 1 , wherein the circlip includes a tab configured to constrain rotation of the circlip.

3. The clutch assembly of claim 2 , wherein the tab mates with a second opening.

4. The clutch assembly of claim 1 , wherein the first opening is a through hole.

5. The clutch assembly of claim 1 , wherein the bushing is press-fit into the hub.

6. The clutch assembly of claim 1 , wherein the clutch assembly is included in a dog clutch.

7. The clutch assembly of claim 6 , wherein the sleeve includes a shift fork interface.

8. The clutch assembly of claim 1 , wherein the first opening includes a lip that radially delimits the ball.

9. The clutch assembly of claim 1 , wherein the detent assembly includes a plurality of openings which each include a ball and spring positioned therein.

10. The clutch assembly of claim 9 , wherein the plurality of openings are symmetrically spaced apart with regard to a central axis of the clutch assembly.

11. A dog clutch assembly, comprising:

a sleeve that at least partially circumferentially surrounds a hub;

a detent assembly positioned in the hub, configured to hold the sleeve and the hub in a defined axial position, and including:

a first through hole with a ball and a spring positioned therein; and

a circlip or a bushing that maintains the spring in the first through hole;

wherein the ball mates with a detent in the sleeve.

12. The dog clutch assembly of claim 11 , wherein the circlip includes a tab that mates with a second through hole and constrains rotation of the circlip, and wherein the second through hole does not include a ball or a spring.

13. The dog clutch assembly of claim 11 , wherein the detent assembly includes a second through hole and a third through hole which include balls and springs positioned therein.

14. The dog clutch assembly of claim 13 , wherein the first through hole, the second through hole, and the third through hole are sequentially spaced apart by 120° with regard to a central axis.

15. The dog clutch assembly of claim 11 , wherein the dog clutch assembly is included in a transmission.

16. The dog clutch assembly of claim 15 , wherein the transmission is an electric transmission.
