INCREASE IN MULTIAXIAL CHASSIS SMOOTHNESS Russian patent published in 2015 - IPC F41H7/00 B62D9/00 B60G23/00 B60G17/00 

FIELD: transport.

SUBSTANCE: claimed process comprises the suspension of uncontrolled wheels without elastic suspension and of controlled wheels with independent torsion suspension. Said independent torsion suspension consists of the guide device, resilient element and fluid-operated leverage-type two-way damper provided with the lever-cam drive. The latter serve to damp the shocks, pushes and the frame vibrations in the motion over terrain irregularities. This method exploits the onboard data control system to receive and process the signals from the equaliser angle deflection transducer and speed transducer. Said onboard data control system outputs the signals, at definite time intervals, to slide-valve box for control over fluid flows from fluid pump via slide-valve box to hydropneumatic cylinders for control over support rolls and machine body position.

EFFECT: automatic stabilisation of wheeled multiaxial chassis, better ergonomics, ruled out suspension.
