Abstract (en)

[origin: WO2008152383A1] A suspension for a rail vehicle includes at least one spring (18) carrying a wedge element (20) constrained to move in a vertical direction and a load application member (24) for engaging the wedge (20) to transmit the load to the wedge (20) along a direction. The damping ration of the suspension is variable by altering the engagement between the load application member (24) and the wedge (20) and hence the direction.
