  • Adjustable shock absorber for a motor vehicle
    Patent number: 6871731
    Abstract: An adjustable shock absorber (8) includes a damping force changing device (16) which continuously adjusts the damping force characteristic of the shock absorber in response to input control signals. A first signal is generated by a first sensor which represents the damping force movement. At least a second signal is generated by at least a second device (10a . . . ) which represents the vertical bodywork speed (VA, 12) and/or the vehicle longitudinal speed (20). Based on this, a control signal (18) for adjusting the damping force characteristic is computed in accordance with a control law in the manner that the change of the desired current can be limited over time.

  • Damper support having a contoured end face for a shock absorber of a motor vehicle
    Publication number: 20040017035
    Abstract: A damper support is provided which is especially for supporting shock absorbers in motor vehicles. The damper support is built in on the vehicle body between two clamping surfaces in axial direction of a piston rod of a shock absorber and is connected through a central opening to the piston rod of the shock absorber. At least one outer axial end face has at least one rise and one low in peripheral direction and the rises and lows of the outer axial end faces generate a waveform in the peripheral direction.
