  • Patent number: 8800734
    Abstract: Vibration damper includes a tubular body to which an external part, which acts as a stop, is fastened. A component such as a steering knuckle, which is supported against the stop, is also fastened to the tubular body. When a normal load on the component is exceeded, a deformation area allows the component to shift on the tubular body.

  • Patent number: 8495816
    Abstract: Method for adjusting the throttling action of a valve comprising a valve body with at least one through-channel for a working medium, where the working medium is throttled by at least one valve disk which covers the throttle channel. By making use of the effect of the heat of a laser beam to change the elastic pretension of the disk, deviations from a predetermined throttling action are minimized. The laser beam is used to cause partial local melting in the minimum of one valve disk, the heat thus introduced having the effect of working at least one defined bending axis into the disk.

  • Publication number: 20090166940
    Abstract: A spring plate for supporting a coil spring of a vibration damper includes a metal base body and a plurality of discrete insulating segments positioned on the base body. Each insulating segment has a contact surface which contacts an end of the coil spring, and an edge part which prevents the spring from migrating radially. Each insulating segment can be replaced independently of the other insulating segments.

  • Patent number: 6974005
    Abstract: Vibration damper comprising a damping medium-filled pressure tube, in which a displacer is installed, where a damping device produces a damping force as a function of the movement of the displacer. A damping force-limiting device, independently of the flow of the damping medium, becomes active above a certain damping force threshold value, which is defined as a function of the vehicle. At least a partial section of the force-limiting device is connected in a fixed manner to the pressure tube below the damping force threshold value and travels an operating distance which is associated with a change in the volume of the pressure tube when the force threshold is exceeded.

  • Patent number: 6467760
    Abstract: Filling valve for a gas bag installed in a space bounded by rigid walls, where the forces of a liquid medium, which is under pressure and which flows into and out of this space, act on this space. The gas bag serves as a compensation space, is filled with gas, and can be filled through a filling valve, which has an access channel aligned with an opening in the rigid wall. The access channel is located in a connector part connected to the gas bag, the connector part also being connected to a guide part resting against the inside surface of the rigid wall, the access channel being in effective connection with the opening in the rigid wall via this guide part.

  • Patent number: 6370451
    Abstract: A hybrid drive for a vehicle in which the driving power provided by an internal combustion engine (ICE) or an electric motor may be fed via a transmission with a transmission input shaft and a transmission output shaft to the drive train. The ICE and the electric motor are connectable to each other via a coupling and the electric motor is directly connected to the transmission. An electric energy storage device is connected to the ICE for receiving a charge and to the electric motor for providing power to the electric motor. The hybrid drive is designed so that the torque that can be provided by the electric motor is greater than that of the internal combustion engine. In addition, the transmission input shaft always turns in the same direction as the transmission output shaft so that reverse drive by the hybrid drive is only possible using the electric motor.
