  • Arrangement for controlled damping of pivoting movements in an articulated bus
    Patent number: 4756543
    Abstract: The invention relates to an arrangement for controlled damping of pivoting movements, preferably in an articulated bus. The arrangement comprises hydraulic dampers arranged between the vehicle units, a hydraulic control system which connects the dampers with each other, and an electrical control system which activates electrically operated valves in the hydraulic control system. The invention is characterized essentially in that it comprises devices which allows the electrical control system, in response to sensors which sense the pivot angle and the vehicle speed, to connect various throttles in the connecting lines between the dampers, to thereby control the damping level of the dampers.
