Abstract

A sealing sleeve for a transmission or a clutch of a motor vehicle for use between two torque transmitting devices, which rotate relative to each other, wherein a shell surface of the sealing sleeve is designed for making contact in a sliding and sealing manner with one or more sealing means; and a flange section, which projects radially from the shell surface, is designed for interpositioning between the two torque transmitting devices, wherein the flange section is formed as a running surface for an axial bearing. An automatic transmission or a clutch with a first torque transmitting device and a second torque transmitting device, between which an inventive sealing sleeve is inserted.

First claim

What we claim is:

1. A sealing sleeve for use between two torque transmitting devices, which rotate relative to each other, comprising:
a shell surface, including:
a radially inward facing surface;
a hook section extending radially inward from the radially inward facing surface and,
a nose extending radially inward from the radially inward facing surface and axially displaced from the hook section in a first axial direction;

a bottom unit, including:
a flange section, having:
a first end that engages the shell surface axially between the hook section and the nose;
a second end; and,
a running surface facing in the first axial direction; and,

a rim extending from the second end in the first axial direction; and,

an axial bearing operatively arranged on the running surface, the axial bearing including a cage connected to the flange section.

2. The sealing sleeve as claimed in claim 1 , wherein the flange section forms a rolling surface for a rolling body of the axial bearing.

3. The sealing sleeve as claimed in claim 1 , wherein the sealing sleeve is securely connected to the axial bearing.

4. The sealing sleeve as claimed in claim 1 , wherein hydraulic fluid passage openings are contained in the shell surface.

5. The sealing sleeve as claimed in claim 1 , wherein the shell surface, the flange section, and the rim comprise a constant thickness.

6. The sealing sleeve as claimed in claim 5 , wherein the flange section and the rim form a cup-shaped, ring-shaped, and/or disk-shaped bottom unit.

7. The sealing sleeve as claimed in claim 6 , wherein the bottom unit is attached to a sleeve base body in a non-positive locking manner and/or a positive locking manner and/or by material bonding.

8. The sealing sleeve as claimed in claim 1 , wherein the sealing sleeve is configured in one part or two parts.

9. An automatic transmission or clutch with a first torque transmitting device and a second torque transmitting device, between which the sealing sleeve is inserted, as claimed in claim 1 .

10. A sealing sleeve for use between two torque transmitting devices, which rotate relative to each other, comprising:
a bottom unit, including:
a flange section, having:
a first end;
a second end arranged radially inward of the first end; and,
a running surface facing in a first axial direction; and,

a rim extending from the second end in the first axial direction;

a shell surface connected to and extending from the first end in the first axial direction; and,
an axial bearing operatively arranged on the running surface and securely connected to the sealing sleeve.

11. The sealing sleeve as claimed in claim 10 , wherein the flange section forms a rolling surface for a rolling body of the axial bearing.

12. The sealing sleeve as claimed in claim 10 , wherein the flange section is connected to a cage of the axial bearing.

13. The sealing sleeve as claimed in claim 11 , wherein the flange section is connected to a cage of the axial bearing.

14. The sealing sleeve as claimed in claim 10 , wherein hydraulic fluid passage openings are contained in the shell surface.

15. The sealing sleeve as claimed in claim 10 , wherein the shell surface, the flange section, and the rim comprise a constant thickness.

16. The sealing sleeve as claimed in claim 10 , wherein the sealing sleeve is configured in one part or two parts.

17. The sealing sleeve as claimed in claim 15 , wherein the flange section and the rim form a cup-shaped, ring-shaped, and/or disk-shaped bottom unit.

18. The sealing sleeve as claimed in claim 17 , wherein the bottom unit is attached to a sleeve base body in a non-positive locking manner and/or a positive locking manner and/or by material bonding.

19. An automatic transmission or clutch with a first torque transmitting device and a second torque transmitting device, between which the sealing sleeve is inserted, as claimed in claim 10 .
