FIELD: transport.SUBSTANCE: invention relates to suppression of vehicle body oscillations at various road conditions. Proposed system comprises resilient and damping elements installed at vehicle body and articulated with suspension rockers. Damping elements are composed by two-mode moment blade hydraulic cylinders to be operated in controlled and uncontrolled modes. Mode changeover units are connected to unlike working chambers of hydraulic cylinders via throttle, check valve and hydraulic booster control valve. For cushioning, suspension damping properties are used to decreased angular and vertical oscillations of the body. In motion, current angular deviations and angular velocities of the body are measured in lengthwise and crosswise plane and vertical velocities of the body centre of gravity. Current required control force acting on the wheel via suspension is calculated. Then control system converts said damping elements into actuators to create control action at the wheel.EFFECT: efficient control over suspension subject to road conditions.2 cl, 3 dwg |
