  • Publication number: 20190162255
    Abstract: A method for the transmission and damping of a mean torque with a superposed alternating torque having an input and an output. The mean and superposed alternating torque is transmitted along a torque path from the input to the output area. An input speed is a mean speed and a superposed alternating component. A slip arrangement is provided in the torque path between the input and the output for transmitting the mean and superposed alternating torque and generating a speed slip between an input speed and an output speed. The slip arrangement provides a maximum of an external activation of the speed slip in a area of the maxima of at least one periodic oscillation component of the alternating component and provides a minimum of an external activation of the speed slip in an area of the minima of at least one periodic oscillation component of the alternating component.

  • Patent number: 10097063
    Abstract: Constructional unit includes an electric machine with a stator and with a rotatable rotor, a rotatable output element operatively communicates with the rotor to transmit torque, and an offset arrangement. The offset arrangement is arranged between the rotor and the output element, and the transmission of torque is enabled in case of an axial offset and/or an angular offset between a rotational axis of the rotor and a rotational axis of the output element.

  • Publication number: 20180252273
    Abstract: A clutch arrangement is formed with drive-side and, output-side clutch elements and a clutch piston for operative connection and disengagement between the drive-side and output-side clutch elements. Associated with at least two clutch elements is an elastically deformable clutch element working mechanism through which the corresponding clutch elements can be acted upon in direction away from one another by an axial force to assist disengagement of the drive-side and output-side clutch elements. The clutch element working mechanism provides a considerable change in the gradient of the axial force exerted on the clutch elements as a result of even a small change of shape of the clutch element working mechanism so that a sharply rising axial force of the clutch element working mechanism works against the clutch piston.

  • Patent number: 7147095
    Abstract: A gearshift mechanism for a motor vehicle with hydraulically actuated multiple clutch, particularly a twin clutch, has a first gear input shaft to drive a first group of gears and a second gear input shaft to drive a second group of gears. The two gear input shafts are each assigned a clutch unit being coaxial to one another. A stationary housing accommodates the two clutch units. At its end face, the housing can be closed off by a housing cover that has a central opening through which a drive hub of a clutch cage is guided. The housing cover is provided with a bearing flange around the central opening, on the outside of which the clutch cage is supported. This advantageously supports the clutch on the housing and makes it possible to achieve a support effect for a dual mass flywheel or the crankshaft end of the internal combustion engine.
