Abstract

See full text

A hanger for an overhead railway line adapted to be fixed between a carrying cable or a bracket and a power supply contact wire comprises:

    a clamp to tighten an undercut portion of the contact wire, and a negative-stiffness elastic device connected to the clamp, the elastic device comprising:a. a pre-compressed elastic assembly along a first direction and having a movable point to shift in a second direction transverse to the first direction so as to decrease the pre-compression following a load disturbance;b. an elastic element connected to the pre-compressed elastic assembly to apply, in the second direction, an action onto the movable point when the clamp is moved upon the passage of a pantograph on the contact wire;c. a spacer to connect the clamp to the elastic element under traction/compression;d. a calibrated friction action being generated upon the movement of the movable point.
