Abstract
A wet clutch assembly may have a clutch drum, a clutch chamber formed within the clutch drum, a clutch actuation piston movably disposed within the clutch drum and configured to be actuated via a hydraulic pressure in the clutch chamber. A fluid line may at least partially extend through the clutch actuation piston, where the fluid line provides fluid communication with the clutch chamber for filling the clutch chamber via the fluid line.
Claims8
A wet clutch assembly, comprising:
- a clutch drum;
- a clutch chamber formed within the clutch drum;
- a clutch actuation piston movably disposed within the clutch drum and configured to be actuated via a hydraulic pressure in the clutch chamber;
- and
- a fluid line at least partially extending through the clutch actuation piston, the fluid line providing fluid communication with the clutch chamber for filling the clutch chamber via the fluid line;
- a flow control member comprised of an axial boring in the clutch actuation piston and first and second radially extending fluid ports in the clutch actuation piston in fluid communication with the axial boring, wherein the first radially extending fluid port has a larger cross section than the second radially extending fluid port;
- wherein both of said first and second radially extending fluid ports open on a same outer wall of the clutch actuation piston and are adapted to be supplied by the same fluid line.

- a clutch chamber formed within the clutch drum;
- a clutch actuation piston movably disposed within the clutch drum and configured to be actuated via a hydraulic pressure in the clutch chamber;
- and
- a fluid line at least partially extending through the clutch actuation piston, the fluid line providing fluid communication with the clutch chamber for filling the clutch chamber via the fluid line;
- a flow control member comprised of an axial boring in the clutch actuation piston and first and second radially extending fluid ports in the clutch actuation piston in fluid communication with the axial boring, wherein the first radially extending fluid port has a larger cross section than the second radially extending fluid port;
- wherein said flow control member is movable relative to a section of the fluid line and configured to vary a cross section of said fluid line section through movement of the clutch actuation piston relative to the clutch drum,
- wherein the clutch actuation piston is configured to transfer the wet clutch assembly from a disengaged state to an engaged state through movement of the clutch actuation piston in an engagement direction relative to the clutch drum, wherein the flow control member is configured to reduce the cross section of said fluid line section through movement of the clutch actuation piston in the engagement direction.
