Abstract
A railway vehicle wheel always improve damping characteristics when a thin visco-elastic layer is placed between the tire and the connecting disc or ring. The visco-elastic layer improves damping through shearing action and has a thickness that is lower than that of the tire by an order of magnitude.
Claims15
Railway vehicle wheel comprising a hub and a tire provided with a flange, which hub and tire are mutually connected by means of a disc or a number of spokes, the tire comprising a thin visco-elastic layer for dissipating vibrations originating from a contact of the railway vehicle wheel with a railway track, wherein the thickness of the visco-elastic layer is of a smaller order of magnitude than the thickness of the tire.
