  • Patent number: 5992582
    Abstract: An electrorheological damping device for reducing translational vibration between two bodies comprises a rotary electrorheological damper and transmission means for converting the translational vibration between the two bodies to the rotary motion of the rotary electrorheological damper. The rotary electrorheological damper includes a stator and a rotor that are coaxially arranged. The stator have a plurality of stator electrodes, and the rotor have a plurality of rotor electrodes. The stator electrodes and the rotor electrodes face each other alternatively within at least one fluid chamber. The fluid chamber is filled with an electrorheological fluid that varies its rheological properties when exposed to an electric field. The electrorheological fluid fills spaces between each pair of the stator and rotor electrodes.

  • Patent number: 4768802
    Abstract: A steerable dolly for a truck trailer resting thereon comprising a steering linkage to turn the dolly wheels relative to the dolly frame, the linkage including an engagement with the trailer that senses the yaw articulation angle of the trailer relative to the dolly frame and causes the linkage to steer the dolly wheels in response to the yaw articulation angle. The steering ratio of the dolly wheels to the yaw articulation angle is a function of the dolly tow bar length for a B-Dolly configuration, the rear overhang of the towing vehicle and the wheel base of the trailer resting on the dolly fifth wheel. The steering ratio may be adjusted by adjusting the effective length of one of the links in the steering linkage.
