DEVICE FOR VIBRATION CONTROL OF RAILWAY CAR Russian patent published in 2018 - IPC B61F5/24 F16F5/00 

FIELD: machine building.

SUBSTANCE: invention relates to devices for damping the vibration of railway wagons. Vibration damping device comprises two semi-active dampers or one semi-active damper and one actuator. Dampers are installed between the car body and the trolley. First damper can work either as a semi-active damper or it can be turned off. Second damper can work either as a semi-active damper or as a passive damper. Executive mechanism is equipped with an additional feed pump, which extends the possibility of damping the oscillations of the car. Control signal is generated by the controller depending on external conditions and driving conditions.

EFFECT: effective damping of vibrations and energy saving are achieved.
