  • Patent number: 8864154
    Abstract: An actuator having an electromechanical drive and a housing is provided. The driving torque provided by an electric motor is transmitted by gear train to two actuator outputs connected to two parts of a stabilizer. The gear train is an eccentric gear train, the drive shaft of which is driven by the electric motor. An overall eccentric driven by the drive shaft has on its circumference a drive gear having a first outer profile and a second outer profile different therefrom. In the operating state the drive gear first outer profile is connected to a first inner profile of a first one of the outputs and the drive gear second outer profile is connected to a second inner profile of the second one of the outputs, and the connection can be eliminated by changing the eccentricity of the eccentric such that both outputs can rotate freely relative to each other.

  • Publication number: 20140028021
    Abstract: An assembly with flanges is provided. The flanges are used for welding onto a pipe end of a pipe for a pressure-bearing flange connection of two pipe ends, wherein the flange extends in a circumferential direction about a central axis of the pipe and has a first end face in the axial direction of the pipe end, wherein the first end face has a sealing groove extending in the circumferential direction, which sealing groove divides the end face into a radially inner inside surface and a radially outer outside surface. In order to avoid rework, the inside surface is axially recessed by a recess on average relative to the outside surface. An adaptation ring or an assembly having a flange or adaptation ring is also provided.

  • Patent number: 8632413
    Abstract: A torsional vibration damper (1) having a damping element disposed between a first element (4) and a second element (5), in which the first element and the second element can rotate relative to each other, with or without a coupling part (3) that is located in a housing (2) and is axially displaceable along an axis (A) between the first and second elements, in which, if a coupling part is present, a) the coupling part is displaceable along the axis (A) against the spring force of at least one spring element (6, 7) and/or b) the coupling part is displaceable along the axis (A) against a medium which acts on both sides of the coupling part, with the medium located in internal or external partial spaces. Alternatively, in a damping element not having a coupling part, c) resilient elements are integrated in third coupling elements, and the coupling elements are connected to the first and second elements.

  • Patent number: 8272650
    Abstract: A low-end adjusting mechanism for vehicle suspensions useful for compensating rolling and pitching motions and for leveling purposes, in which a vehicle spring (1) having a longitudinal axis is mounted between two spring seats or receptacles (2, 3), and at least one spring seat can be adjusted in the direction of the longitudinal axis of the spring by rod shaped coupling elements which are mounted at both ends in an articulated or pivotable manner.

  • Patent number: 7992485
    Abstract: An apparatus for compensating and/or transmitting forces/torques and rotational movements between two components, particularly for compensating for vehicle movements, in which at least one joint module is situated between the two components, which joint module converts a translational and/or rotational movement of a piston, to which a pressure medium is applied, into a rotational movement of at least one first rotatable shaft or of a first and a second rotatable shaft.
