FIELD: machine building.
SUBSTANCE: shock-absorber contains casing with the hydraulic cavity filled with the magnetic rheological liquid. The channel connects two parts of the cavity. Stock contains wires and magnet. The magnet contains two concentric solenoids. The control device changes current in the magnet winding depending on speed of the piston movement. The solenoid sensor supplied to the control device the electric signal proportional to speed of the piston movement. The speed sensor is made in form of the solenoid winding secured on the stock and moving in the magnetic field of the neodymium magnet.
EFFECT: improved damping characteristics.
