  • Patent number: 10363788
    Abstract: A vibration damper is provided for a vehicle, preferably for a motor vehicle, having a wheel carrier made of metal for rotatably receiving a wheel, a damper tube arrangement at least partly made of a fiber-reinforced plastic for forming a damper fluid volume, a piston which is guided in the damper tube arrangement and includes a piston rod. The damper tube arrangement is rigidly connected to the wheel carrier and the piston rod can be connected to a body of the vehicle. A wheel carrier fluid volume is formed in the wheel carrier and which is connected to the damper fluid volume. The fluid in the wheel carrier fluid volume is in direct contact with the metal of the wheel carrier in order to transfer heat.

  • Patent number: 9758004
    Abstract: A vibration damper for a vehicle is provided. The vibration damper includes at least one damping cylinder made from a fiber composite material; a guiding element for guiding a piston rod of a piston movably arranged in the damping cylinder. The guiding element is located in a guiding end region at one end of the damping cylinder. A fastening element for use in attaching the at least one damping cylinder to a vehicle is located at a fastening end of the cylinder. At least one of the two end regions of the damping cylinder is conical or wedge-shaped and its element has a corresponding external form that is conical or wedge-shaped. A conical or wedge-shaped clamping sleeve located around the conical or wedge-shaped end regions of the damping cylinder.

  • Patent number: 9694557
    Abstract: A plastic component, with fiber reinforcement, for use in a motor vehicle. The plastic component comprises a number of fiber layers connected to one another by injection of plastic and by a pressing force. The plastic component comprises at least two structural parts which overlap one another a pressing direction such that the die comprises at least one upper die portion formed with a pressing unit for applying a pressing force in the pressing direction, and at least one lower die portion which cooperates with the upper die portion to form a cavity in which the plastic component is formed. A die insert is fitted in the die and can move by and with the upper die portion and is designed to transmit the pressing force to the at least one structural part of the plastic component which is overlapped by the other structural part of the plastic component in the pressing direction.

  • Patent number: 9555683
    Abstract: A four-point link for the suspension of a rigid axle which has four bearing seats. Two bearing seats can be articulated on the axle and two can be articulated on the vehicle frame. The link has a single-piece link body which is inscribed by the trapezoid formed by the bearing seats. The link body is formed of a fiber-composite arrangement that comprises at least one longitudinal fiber arrangement. The longitudinal fiber arrangement encases the bearing seat, at least along half circumference thereof and extends along at least a portion of the link body in order to optimize loading, reduce mass and increase its application. Torsional compliance makes it possible to use relatively small and/or hard rubber bearings for articulating the four-point link or the vehicle axle.

  • Publication number: 20140207328
    Abstract: A method for the diagnosis of defects in components of motor vehicle chassis systems. Vibrations produced by rotating components of the chassis system due to an imbalance are filtered such that the frequency range which depends on the wheel rotation speed and contains the imbalance-induced vibrations of the rotating components is filtered out. The signals from sensors associated with the component and arranged on the wheel carrier side and the vehicle body side, are received and stored. The amplitudes of these signals are sorted by increasing frequency and the mechanical impedance of the transmission chain is determined and compared with the known impedance of that component undamaged. If a deviation of the determined impedance for the component and the known impedance of the undamaged component is recognized, then the component is determined to have a defect and a flag is set.
