  • Publication number: 20150247551
    Abstract: A torsional vibration damping arrangement for transmitting a rotation from an input side to an output side includes a first and second torque transmission path arranged between the input side and the output side. A coupling arrangement serves to superpose the first torque component and second torque component. A phase shifter arrangement serves to generate a phase shift between torsional vibrations which are transmitted to the coupling arrangement via the first and second torque transmission paths, wherein the phase shifter arrangement comprises an oscillatory system with a primary side coupled with the input side and a secondary side which is rotatable with respect to the primary side and which is connected to the coupling arrangement. An effective mass moment of inertia of the secondary side inhibiting a change in a rotational velocity of the secondary side is dependent upon the rotational velocity.

  • Patent number: 9086136
    Abstract: A gearwheel for a planetary gear train includes two working toothing regions arranged successively in direction of a gearwheel rotational axis (Z). A first working toothing region is arranged at a first gearwheel part, and a second working toothing region is arranged at a second gearwheel part. The two gearwheel parts are connected to one another by positive engagement and/or bonding engagement and/or frictional engagement so as to rotate together around the gearwheel rotational axis (Z) and/or against relative movement with respect to one another in direction of the gearwheel rotational axis (Z).

  • Publication number: 20150192190
    Abstract: A torsional vibration damping arrangement (10) for the drivetrain of a vehicle comprises an input region (50) to be driven in rotation around an axis of rotation (A) and an output region (55), and a first torque transmission path (47) and parallel thereto a second torque transmission path (48) which proceed from the input region, and a coupling arrangement (44) for superposing the torques guided via the torque transmission paths (47; 48), which coupling arrangement (44) communicates with the output region (55), and a phase shifter arrangement (43) for the first torque transmission path (47) for generating a phase shift of rotational irregularities guided via the first torque transmission path (47) relative to rotational irregularities guided via the second torque transmission path (48). The torsional vibration damping arrangement is formed with an axial distance between the phase shifter arrangement (43) and the coupling arrangement (44) to form a passage space for at least one driveshaft (39) of a vehicle.

  • Publication number: 20140123929
    Abstract: A drive system for a vehicle has an internal combustion engine and a torsional vibration damping arrangement. The internal combustion engine is switchable between operating modes of different performance. The torsional vibration damping arrangement includes an input region, which can be driven in rotation, and an output region. A first torque transmission path is provided between the input region and output region, and a second torque transmission path is provided parallel thereto. A coupling arrangement superposes the torques transmitted via the torque transmission paths, and a phase shifter arrangement is provided in at least one torque transmission path for generating a phase shift of rotational irregularities transmitted via the one torque transmission path in relation to the rotational irregularities transmitted via the other torque transmission path.

  • Publication number: 20140102398
    Abstract: A drive system for a vehicle comprises an internal combustion engine switchable between operating modes of different performance capability, and a torsional vibration damping arrangement that comprises a primary side preferably coupled to a crankshaft and a secondary side rotatable with respect to the primary side against the action of a damper element arrangement. The damper element arrangement has a stiffness which increases as the load torque to be transmitted increases, and the primary side and the secondary side are in a limiting relative rotational position with respect to one another during transmission of a maximum torque which can be delivered in an operating mode with lower performance capability at a maximum torque rotational speed, and the damper element arrangement provides a limiting stiffness in the limiting relative rotational position such that a natural frequency of the torsional vibration damping arrangement is below the maximum torque speed.
