Electromagnetic vibrations damper

摘要

The present invention relates to a vibrations damper mounted between two mechanical members subjected to vibrations and comprising a body 3 delimiting a chamber 6 filled with fluid and connected, elastically or telescopically, by means of attachment components 1, 2 to the said mechanical members. The damper according to the invention is characterised in that it comprises an electromagnetic driver 4 provided with at least one coil 41 supplied with electric current and capable of creating a magnetic field in the fluid formed by a mixture of liquid with hydraulic characteristics and particles made from a magnetic material so as to have a viscosity which is adjustable via the effect of the magnetic field and so as thus to control the damping. The damper according to the invention applies particularly to the elastic suspension of heat engines of vehicles on their support chassis. <IMAGE>
