Abstract
A torque converter is provided with a turbine hub with a pair of flow channels formed therein. In embodiments, the torque converter has a clutch piston configured to engage or disengage a disconnect clutch. On one side of the clutch piston is an apply chamber configured to receive fluid, wherein the fluid when subjected to pressure moves the clutch piston to engage the clutch. On the other side of the clutch piston can be a second fluid chamber, such as a circulation chamber or a release chamber. The turbine hub has a pair of flow channels formed therein, one that supplies fluid directly to the apply chamber, and one that supplies fluid directly to the second fluid chamber.
Claims20
A four-pass torque converter comprising:
- a cover configured to rotate about a central axis;
- a turbine hub configured to rotate about the central axis;
- a clutch plate configured to slide axially relative to the turbine hub to selectively open and close a disconnect clutch;
- a compensation chamber at least partially bound by one side of the clutch plate;
- and
- an apply chamber at least partially bound by an opposite side of the clutch plate relative to the compensation chamber, wherein an application of pressurized fluid in the apply chamber moves the clutch plate in an axial direction to close the disconnect clutch;
- wherein the turbine hub includes:
- a first fluid channel formed therein and configured to supply fluid to the compensation chamber, and
- a second fluid channel formed therein and configured to supply fluid to the apply chamber.
A three-pass torque converter comprising:
- a cover configured to rotate about a central axis;
- a turbine hub configured to rotate about the central axis;
- a clutch plate configured to slide axially relative to the turbine hub to selectively open and close a disconnect clutch;
- a pressure chamber at least partially bound by one side of the clutch plate;
- and
- an apply chamber at least partially bound by an opposite side of the clutch plate relative to the pressure chamber, wherein an application of pressurized fluid in the apply chamber moves the clutch plate in an axial direction to close the disconnect clutch;
- wherein the turbine hub includes:
- a first fluid channel formed therein and configured to supply fluid to the pressure chamber, and
- a second fluid channel formed therein and configured to supply fluid to the apply chamber.
A torque converter comprising:
- a cover;
- a turbine;
- a turbine hub non-rotatably coupled or integrally formed with the turbine;
- a clutch plate configured to slide axially along to the turbine hub to selectively open and close a disconnect clutch;
- a first pressure chamber at least partially bound by a first side of the clutch plate;
- and
- a second pressure chamber at least partially bound by a second side of the clutch plate;
- wherein the turbine hub includes:
- a first fluid channel extending axially therethrough configured to supply fluid to the first pressure chamber, and
- a second fluid channel extending radially therethrough and configured to supply fluid to the second pressure chamber.
