  • Publication number: 20220099061
    Abstract: A method actively dampens a start-up resonance of a torsional damper when starting an internal combustion engine. The torsional damper (4) is fixed between an internal combustion engine (1) and a secondary side (5) of a torsional elasticity, and the internal combustion engine (1) is started using a starter generator (3) arranged on a side of the internal combustion engine (1) counter to the torsional elasticity. A counter excitation is applied to a torque generated by the starter generator (3) when the internal combustion engine (1) is started, which counter excitation is modulated on the basis of a parameter of the internal combustion engine (1) which changes when the internal combustion engine (1) is being started.

  • Patent number: 10060516
    Abstract: An oil-flooded single-plate or multi-plate lockup clutch is provided in a torque transfer device. The torque transfer device may, for example, be a converter, a dual clutch, a starting clutch, a manual shifter, or power shifting clutch, having a piston to engage the clutch and a damper. In accordance with the present disclosure, the piston together with a housing of the torque transfer device forms a closed pressure chamber when the clutch is engaged and at least one oil flow opening is provided in the piston in an area outside of the pressure chamber. The torque transfer device preferably has a damper and the piston of the clutch forms a part of the damper and may be designed as a retainer for springs of the damper.

  • Patent number: 9683629
    Abstract: A centrifugal force pendulum having a pendulum mass pair and a pendulum flange, in which an arcuate cut-out with a cut-out contour is provided, wherein the pendulum masses of the pendulum mass pair are situated on both sides of the pendulum flange and are connected to each other by at least one spacer bolt which is guided through the cut-out, wherein the spacer bolt has a damping arrangement which includes a stabilizing element and an elastic damping element, wherein the damping element is designed to damp a striking of the spacer bolt on the cut-out contour of the cut-out, wherein the damping element and the stabilizing element of the damping arrangement are positioned relative to each other so that the damping element is able to strike the cut-out contour of the cut-out directly.

  • Patent number: 9038793
    Abstract: Centrifugal pendulum device including pendulum masses arranged on axial sides of a pendulum mass support rotatable about an axis of rotation to form a pendulum mass pair. To form the mass pair, the masses are fastened to each other by means of a fastener passing through a cutout in the mass support. The mass pair is pivotable relative to the mass support due to a rolling element arranged to roll in a recess of the mass support and of the mass. In a section axially covering the recess of the mass support, the rolling element has a first outer diameter. In a section axially covering the recess of the pendulum mass, the rolling element has a second outer diameter. The rolling element further comprises a section axially located between the first and second diameters and has a third diameter, which is smaller than or equal to the first outer diameter.

  • Publication number: 20070181396
    Abstract: A three-channel torque converter in which an additional wall is mounted, thereby creating a third space which hydraulically connects the end of the plates that faces away from the turbine to a third channel. This third space ensures that an exchange flow of oil in a region of the hydrodynamic components (impeller, turbine, stator), of an optional damper, and of the lockup clutch is always restricted to flow across the plates of the lockup clutch. This provides high-performance cooling of the plates in the slip mode.

  • Patent number: 6168401
    Abstract: An hydraulic conveying device, in particular for conveying diesel fuel for an internal-combustion engine in motor vehicles, with a housing provided with at least one conveying chamber as well as a displacement unit rotor arranged in the conveying chamber. Rotation of the displacement unit forms pump chambers with varying volumes by means of which a fluid is conveyed from a suction connection of the conveying device to a pressure connection of the conveying device. The conveying devices includes a screen or wall with openings for retaining a quantity of the fluid to be conveyed in the conveying chamber when a supply of fluid by way of the suction connection is interrupted.
