Abstract
The invention relates to a device for transmitting the torque. The inventive device comprises at least one first and at least one second coupling device which can be switched into different switching positions respectively. The inventive device further comprises a drive device and an actuating device.
Claims50
A torque transfer device comprising
- at least a first clutch device which is a power shift clutch device and which has a first input device and a first output device wherein this input device turns relative to the first output device under predetermined conditions;
- and
- at least a second clutch device which is a start-up clutch and which has a second input device and a second output device wherein this second input device turns relative to the second output device under predetermined conditions;
- wherein
- the first and the second clutch device are mounted inside a drive train between a drive side and an output side;
- the inertia masses of the first input device and the first output device are different;
- the inertia masses of the second input device and the second output device are different;
- and
- the one of these devices of the first clutch device which has the greater inertia mass and/or the one of these devices of the second clutch device which has the greater inertia mass faces the output side.

- at least a first clutch device which is a power shift clutch device and which has a first input device and a first output device wherein this input device turns relative to the first output device under predetermined conditions;
- and
- at least a second clutch device which is a start-up clutch and which has a second input device and a second output device wherein this second input device turns relative to the second output device under predetermined conditions;
- wherein
- the first and second clutch device are mounted inside a drive train between a drive side and an output side;
- the first and second clutch device are connected in parallel inside the drive train so that the first clutch device is mounted substantially in a first drive train branch and the second clutch device is mounted substantially in a second drive train branch connected in parallel with the first;
- the first and second clutch device has on the drive and/or output side a first device which is associated with both clutch devices;
- the first and second clutch device can be loaded on the drive side by a device with a first mass;
- the first clutch device is configured so that a load acting on the first clutch device and on at least a component part coupled thereto and which load is transferred through the device with the first mass under predetermined conditions causes the first clutch device and/or the at least one coupled component part to react to this load due to a series connection of a first spring and/or damping device with a second mass connected in behind in the output direction and an adjoining first separating device (134) which can at least restrict the torque transfer, as well as with a third mass adjoining this separating device on the output side.
