Abstract

Claims (49)

1. A wet friction clutch, comprising:

at least one rotatable clutch component, rotatable around a shaft, further comprising:

a plate carrier or an inner plate carrier; and,

a rotary valve component:

rotatable around the shaft;

formed in the interior of the rotatable clutch component; and,

deflectable by an angle of deflection relative to the rotatable clutch component by a relative rotation around the shaft;

wherein the rotatable clutch component has at least one first opening and the rotary valve component has at least one second opening; and,

wherein a total opening is revealed by an at least partial overlapping of the first opening and the second opening, the size of the total opening being dependent on the angle of deflection.

2. The wet friction clutch according to claim 1 , wherein at least one means of adjustment is formed on the rotary valve component, the adjustment means having an attack surface in a circumferential direction relative to the shaft.

3. The wet friction clutch according to claim 1 , wherein the at least one first opening and the at least one second opening are formed in a circumferential surface relative to the shaft.

4. The wet friction clutch according to claim 1 , wherein at least one restoring means is formed, which causes a restoring force to a predefinable angle of deflection.

5. The wet friction clutch according to claim 1 , wherein the rotatable clutch component and the rotary valve component each have at least one inflow opening through which a liquid enters axially during operation.

6. The wet friction clutch according to claim 1 , wherein a means of acceleration is formed which causes an acceleration of the coolant radially outward from the interior of the rotatable clutch component and of the rotary valve component during operation.

7. The wet friction clutch according to claim 6 , wherein the means of acceleration includes a component with vane structures that is rotatable around the shaft.

8. A wet friction clutch, comprising:

at least one rotatable clutch component, rotatable around a shaft, comprising:

at least one plate carrier including a first plurality of inflow openings;

a rotary valve component disposed radially inward relative to the at least one rotatable clutch component and including a second plurality of inflow openings;

a rotatable clutch component interior portion, disposed radially inward relative to the at least one rotatable clutch component and the rotary valve component; and

a restoring means for exertin a restoring force on the rota valve component.

9. The wet friction clutch of claim 8 , wherein the at least one rotatable clutch component and the rotary valve component are rotatable at same or different rotational speeds.

The wet friction clutch of claim 9 , wherein the at least one rotatable clutch component and the rotary valve component are rotatable at different rotational speeds, and the first plurality of inflow openings and the second plurality of inflow openings are at least partially alignable to permit axial flow of a coolant into the interior portion.

11. The wet friction clutch of claim 9 , wherein the at least one rotatable clutch component and the rotary valve component are rotatable at same rotational speeds, and the first plurality of inflow openings and the second plurality of inflow openings are misaligned thereby blocking axial flow of a coolant into the interior portion.

12. The wet friction clutch of claim 11 , wherein the rotary valve component includes a restoring means, wherein the restoring means is at rest.

13. The wet friction clutch of claim 8 , wherein

the at least one rotatable clutch component further comprises a first circumferential surface including a first opening;

the rotary valve component comprises a second circumferential surface including a second opening, where the second opening includes a means of adjustment; and

wherein the first opening and the second opening at least partially overlap to form a total opening.

14. The wet friction clutch of claim 13 , wherein the rotary valve component is rotatable around the shaft and is deflectable relative to the rotatable clutch component by a relative rotation around the shaft.

15. The wet friction clutch of claim 13 , wherein the means of adjustment protrudes circumferentially inward toward the interior portion and includes an attack surface, wherein the attack surface is oriented at a non-zero angle relative to the circumferential direction.

16. The wet friction clutch of claim 15 , wherein the means of adjustment deflects the coolant radially outward, and wherein the rotary valve component is deflectable relative to the rotatable clutch component to increase the total opening.

17. The wet friction clutch of claim 16 , wherein

the at least one rotatable clutch component and the rotary valve component are rotatable at different rotational speeds;

the first plurality of inflow openings and the second plurality of inflow openings are at least partially alignable to permit axial flow of a coolant into the interior portion; and
