Torque transmission device
View Patent ↗A torque transmission device in the drive train of a motor vehicle for transmitting torque, which has a clutch, particularly a dual-clutch, and a support tube that extends in the axial direction towards a housing, essentially a gear mechanism housing, and is radially arranged within at least one actuator bearing, in particular two actuator bearings, as well as a bearing device for the clutch. Part of the clutch cover facing the housing is supported by the bearing device for the clutch.
1. A torque transmission device in a drive train of a motor vehicle for a transmission of torque, comprising:
a dual clutch having a first clutch plate and a second clutch plate;
a first transmission input shaft, the first clutch being connected to the first transmission input shaft;
a second transmission input shaft, the second clutch being connected to the second transmission input shaft;
a support tube extending axially toward a transmission housing, the support tube arranged radially outside of the second transmission input shaft and radially within two actuating bearings for the dual clutch; and
a bearing device for the dual clutch,
wherein a clutch cover part, which faces the transmission housing, is supported on the bearing device for the dual clutch, the clutch cover part has axial projections that extend axially through an actuating spring device toward a flange part, the flange part is fastened to the axial projections and is supported on the bearing device for the dual clutch, and
wherein the bearing device for the dual clutch is arranged axially between the actuating bearings and the clutch plates.
2. The torque transmission device of claim 1 , wherein the bearing device for the dual clutch is arranged radially between the support tube and the flange part.
3. The torque transmission device of claim 2 , wherein the support tube is fastened to the transmission housing.
4. The torque transmission device of claim 1 , wherein the axial projections are pins.
5. A torque transmission device in a drive train of a motor vehicle for a transmission of torque, comprising:
a dual clutch;
a support tube extending axially toward a transmission housing and radially within two actuating bearings for the dual clutch,
a bearing device for the dual clutch,
wherein the bearing device for the dual clutch is arranged radially, between an end of the support tube, which is on a same side as the transmission housing, and a support element, which is fixed to the transmission housing, and
wherein axial projections are provided on a clutch cover part, the axial projections extending axially through an actuating spring device toward a fastening section which is fastened to the axial projections.
6. The torque transmission device of claim 5 , wherein the axial projections are pins which extend axially through an actuating spring device toward a clutch cover part, and which are fastened to the other end of the support tube.
7. The torque transmission device of claim 5 , wherein the axial projections are pins.
