- the described devices and modules of the prior art are not designed with regard to their resilience by torque of a drive unit for motor vehicles in which particularly high torques are present on components in the torque transmission path between an internal combustion engine and an output shaft. For example, this is particularly the case for sports and commercial vehicles on the American market.
- Known torque transmission devices have a not inconsiderable axial installation space requirement and accordingly require a relatively extensive design adaptation to the structural restrictions in a drive train, in particular in a hybrid drive train.
- the present invention has for its object to provide a torque transmission device and a hybrid module equipped with it and a drive train, the space requirement with a small axial construction and long life ensure optimal operation of a vehicle equipped with it.
- axial and radial always refer to the axis of rotation of the torque transmission device or its disconnect clutch.
- the invention relates to a torque transmission device, comprising a clutch with an input side for mechanical coupling of the clutch with a drive shaft, in particular a crankshaft of an internal combustion engine, and with an output side for mechanical coupling of the clutch with an output shaft, in particular with a transmission input shaft.
- a torque transmission device comprising a clutch with an input side for mechanical coupling of the clutch with a drive shaft, in particular a crankshaft of an internal combustion engine, and with an output side for mechanical coupling of the clutch with an output shaft, in particular with a transmission input shaft.
- the drive shaft or the crankshaft of the internal combustion engine can e.g. be coupled by a Hirth toothing and a central screw to the torque transmission device, or to an element of the torque transmission device connected to the input side of the separating clutch in a rotationally fixed manner.
- the disconnect clutch is designed as a normally open clutch.
- the clutch without active application of force to the separating clutch, the clutch remains in an open state and the torque transmission path between the input side and the one is closed only when an appropriate contact pressure is exerted on the friction plates of the separating clutch via the pressure pot Output side of the clutch and consequently between a connected internal combustion engine and an electrical machine or between the drive shaft and the output shaft is realized.
- This version is particularly suitable for motor vehicles that are designed with hybrid technology, that is, in addition to the internal combustion engine, also have an electric drive unit, which enables the vehicle to be driven by an electric motor over long distances without having to operate the internal combustion engine.
- the separating clutch comprises a compression spring which acts upon the pressure pot with an axial elastic restoring force in the event of axial deformation.

- the torque transmission device has an actuation system for applying an axially acting force to the pressure pot.
- the pressure pot has a crank, which makes it possible to arrange the pressure pot and the actuation system axially and radially ne at least in regions.

- Such an actuation system can have a piston-cylinder unit as a hydraulically operable actuator, which can hydraulically provide the axially acting force for closing the separating clutch via axial displacement of the pressure pot.

Furthermore, the centrifugal pendulum comprises a second flange, which oscillates with the Pendulum mass unit is coupled. The first and second flanges are rigidly connected to one another by so-called spacer bolts. The pendulum mass unit is thus coupled to the two rigidly connected flanges.
- the pendulum mass unit can be composed of two individual pendulum masses two an individual centrifugal pendulum, so that the centrifugal pendulum of the inventive torque transmission device is composed essentially of two centrifugal pendulums.
- the centrifugal force pendulum can in particular be arranged radially on the outside in an interior enclosed by a housing of the torque transmission device.

- the vibration damper When the vibration damper is arranged in the torque transmission device, it can also be taken into account in particular that an arrangement of the separating clutch is realized radially inside the vibration damper. This means that the vibration damper is to be arranged as far as possible radially outside in the torque transmission device so that the installation space required by a separating clutch is available radially further inside. This can be provided in particular when designing the disconnect clutch for use in a torque transmission path with a high torque requirement, since accordingly the design of the disconnect clutch with a large number of disks requires more installation space for it.
- the output side of the vibration damper is rotatably coupled to the input side of the separating clutch, in particular to an outer disk carrier of the separating clutch.

- the sealing lip arranged firmly on the sealing element can abut to realize the sealing effect on the drive shaft, on an input flange of a vibration damper or on one of these two components firmly connected element. It is particularly important to ensure that the sealing lip is positioned radially as far inside as possible, so that the lowest possible rotational speed and therefore as little friction as possible between the sealing lip and the adjacent element, so that less wear occurs on the sealing lip.
