A torque transmitting device for a drive train for transmitting an input torque provided by at least one drive element to an output element. The device including: an electric motor having a stator and a rotor which can be rotated relative to said stator for providing a further drive torque; a separating clutch arranged operatively between the first drive element and the electric motor; and at least one centrifugal pendulum which is arranged operatively between the separating clutch and the output element and has at least two pendulum masses which are accommodated so as to be deflectable to a limited extent along a pendulum path and so as to be peripherally adjacent to one another on at least one pendulum mass carrier that can be rotated about an axis of rotation, wherein the peripherally adjacent pendulum masses are coupled to one another via coupling means.

Torque transmitting device

A torque transmitting device for a drivetrain for transmitting a drive torque to an output element. The device having: an electric motor with a conversion unit, which comprises a stator and a rotor that is rotatable relative to the stator, for converting electrical energy into mechanical energy; and a torsional vibration damper with a damper mass received on a damper mass support such that the damper mass can be deflected to a limited extent against the action of a restoring force, the damper mass being arranged so as to overlap radially with the conversion unit.

A centrifugal pendulum which is mountable rotatably around an axis of rotation, having a pendulum flange, a first pendulum mass and a second pendulum mass, where the first pendulum mass is coupled with the pendulum flange by means of a slotted guide, where the slotted guide is designed to guide the first pendulum mass along a first oscillation path in a first oscillating motion, where the second pendulum mass is coupled with the first pendulum mass by a coupling means where the coupling means is designed to guide the second pendulum mass along a second oscillation path in a second oscillating motion.

Centrifugal pendulum

A centrifugal pendulum device has a pendulum mass carrier and at least two pendulum masses that are pivotably received on it along a pendulum raceway and are adjacent circumferentially, wherein the pendulum masses are operatively coupled with one another by elastic coupling means and the elastic coupling means includes a guide element.

A roller () for a pendulum mass () of a centrifugal force pendulum (), including a rolling section (), a first maintaining section () and a second maintaining section (). The maintaining sections have a larger diameter than the rolling section, and the roller () has a width () which is smaller or the same size as the first depth () of the centrifugal force pendulum. Due to roller (), a centrifugal force pendulum can be constructed for particularly flat couplings. In particular, the total weight of the friction clutch is reduced and the mounting is simplified.

A wet friction clutch comprising at least one clutch component which is rotatable around a shaft, wherein in the interior of the clutch component a rotary valve component that is rotatable around the shaft is formed which is deflectable by an angle of deflection in comparison to the rotatable clutch component by a relative rotation around the shaft, wherein the rotatable clutch component has at least one first opening and the rotary valve component has at least one second opening, wherein a total opening is released by an at least partial overlapping of the first opening and the second opening, the size of the total opening being dependent on the angle of deflection.

A torsion vibration damper for a drive train of a motor vehicle, in particular a drive train of a hybrid vehicle, comprising: a spring support and a force transmission flange configured rotatable relative to the spring support, wherein at least one compression spring is provided between the spring support and the force transmission flange for transferring a mechanical torque, wherein a housing of the spring support is configured so that in a radial direction of the torsion vibration damper, at least one longitudinal end of the compression spring is supported at/in the spring support housing and/or a clearance remains between windings of a center section of the compression spring and a wall of the spring support.

A transmission for operating an auxiliary assembly in a drivetrain of a hybrid vehicle, includes a first sun gear rotatable about a main axis on a drive input side of the transmission, a first planet gear in engagement with the first sun gear on the drive input side of the transmission, a second planet gear on a drive output side of the transmission and mounted with the first planet gear on a common shaft, and a second sun gear in engagement with the second planet gear on the drive output side of the transmission, for coupling to the auxiliary assembly. The first planet gear is connected to the shaft by a first freewheel, which generates a rotationally conjoint connection when the first planet gear overruns in a first direction of rotation, and generates a freewheeling connection when the first planet gear overruns in a second, opposite direction of rotation. The shaft is mounted in a second freewheel in a planet carrier, which second freewheel permits a rotation of the shaft when the shaft rotates about its axis in the first direction of rotation and blocks a rotation of the shaft in the second, opposite direction of rotation.
