Multi-plate clutch and hydrodynamic torque converter device having said multi-plate clutch
View Patent ↗A multi-plate clutch ( 2 ) having a first plate carrier ( 48 ) and second plate carrier ( 50 ) and one or more first plates ( 52 ) received by the first plate carrier and one or more second plates ( 54 ) received by the second plate carrier, a pressure element ( 58 ) which can especially be actuated hydraulically for generating an axial load on the clutch pack configured by the first and second plates and closing the multi-plate clutch, in which the pressure element configuring the second plate carrier and/or being connected to the second plate carrier in a rotationally fixed manner.
1. A hydrodynamic torque converter device, comprising:
a turbine;
a torsion vibration damper with an input component connected to the turbine such that rotation of the input component is fixed to rotation of the turbine; and,
a multi-disk clutch including:
a first disk carrier;
a second disk carrier;
at least one first disk arranged to be received by the first disk carrier;
at least one second disk arranged to be received by the second disk carrier; and,
a press component, wherein the at least one first disk and the at least one second disk form a disk packet, wherein the press component is hydraulically actuatable and arranged to generate an axial load onto the disk packet for closing the multi-disk clutch, wherein the press component is integrally formed with the second disk carrier or is non-rotatably connected to the second disk carrier, wherein the press component is integrally formed with the input component of the torsion vibration damper or is non-rotatably connected to the input component, and wherein an additional mass is non-rotatably connected to the input component.
2. The hydrodynamic torque converter device recited in claim 1 , wherein the second disk carrier is disposed radially inside the first disk carrier.
3. The hydrodynamic torque converter device recited in claim 1 , wherein the press component comprises a piston, the piston being supported axially movable.
4. The hydrodynamic torque converter device recited in claim 1 , wherein the at least one first disk and the at least one second disk includes a friction liner.
5. The hydrodynamic torque converter device recited in claim 1 further comprising: a converter torus having a pump shell, a turbine shell and a stator shell; and, a converter lockup clutch comprising the multi-disk clutch.
6. The hydrodynamic torque converter device recited in claim 5 , wherein the torsion vibration damper comprises a first energy accumulator means including at least one first energy accumulator.
7. The hydrodynamic torque converter device recited in claim 6 , wherein the torsion vibration damper further comprises a second energy accumulator means including at least one second energy accumulator, wherein the first energy accumulator means is disposed in a torque path between the converter lockup clutch and the second energy accumulator means when the converter lockup clutch is closed.
8. The hydrodynamic torque converter device recited in claim 5 further comprising a converter housing, wherein the torsion vibration damper, the converter torus and the converter lockup clutch are at least partially received in the converter housing, wherein the first disk carrier is non-rotatably disposed relative to the converter housing, and wherein the disk packet is arranged such that the converter housing supports the disk packet under a pressure loading onto the disk packet from the press component for partial or complete closing of the multi-disk clutch on a side of the disk packet opposite to the piston.
9. The hydrodynamic torque converter device recited in claim 8 , wherein the converter housing comprises an inside, the inside having a raised profile arranged for axial support of the disk packet and a profile indentation arranged for axial profile overlap of the second disk carrier, when closing the multi-disk clutch.
10. The hydrodynamic torque converter device recited in claim 6 , wherein the torsion vibration damper comprises an output component coupled to an output shaft such that the rotation output component is fixed to rotation of the output shaft, wherein the turbine shell is independently rotatable, about an axis of rotation, with respect to the output shaft.
