  • Road vehicle cab attitude controlling apparatus
    Patent number: 5555501
    Abstract: A vehicle cab attitude control system, in which a pair of hydraulic actuators control longitudinal movements between a vehicle frame and portions of the cab located on opposite sides of the cab's center of gravity and spaced vertically therefrom. The hydraulic actuators are controlled dependent on detected changes in longitudinal positions of the cab portions to suppress changes in longitudinal cab attitude. The suppression compensates for existing longitudinal inputs, thus improving riding comfort.
