摘要
A hanger (5) for an overhead railway line adapted to be fixed between a carrying cable or a bracket and a power supply contact wire (4) comprises: a clamp (8) to tighten an undercut portion of the contact wire, and a negative-stiffness elastic device (10) connected to the clamp, the elastic device comprising: a. a pre-compressed elastic assembly (11) along a first direction (A) and having a movable point (12) to shift in a second direction (B) transverse to the first direction (A) so as to decrease the pre-compression following a load disturbance; b. an elastic element (13) connected to the pre-compressed elastic assembly (11) to apply, in the second direction (B), an action onto the movable point (12) when the clamp (8) is moved upon the passage of a pantograph on the contact wire; c. a spacer (14) to connect the clamp (8) to the elastic element (13) under traction/compression; d. a calibrated friction action being generated upon the movement of the movable point (12).
