VIBRATION DAMPER WITH ACTIVE CONTROL, DAMPING SYSTEM AND VEHICLE Russian patent published in 2023 - IPC F16F9/20 

FIELD: mechanical engineering.

SUBSTANCE: group of inventions relates to the field of mechanical engineering. The damper with active control contains a hydraulic cylinder, a piston, an oil reservoir and a reverse valve. The cylinder blocks communicate with the oil tank by means of two oil pipelines. The reverse valve is installed between two oil lines and the tank. The damper additionally contains two parallel branches communicating with the oil lines. The branches contain a single-way throttle valve and an adjustable solenoid valve communicating in series. The damper additionally contains an emergency oil line having two ends connected respectively to the two main oil lines. The emergency oil line contains an emergency throttle valve and an unregulated electromagnetic switching valve connected in series. The two cylinder blocks communicate with the reverse valve by means of two main oil lines. The reverse valve communicates with the oil tank by means of two oil lines of the drive and has two switchable operating positions. The damping system includes such a damper. The vehicle includes such a damping system.

EFFECT: it is possible to adjust the operational parameters of the damper.
