Official abstract text for this publication.
A brake assembly is provided that may include a first friction ring having a plurality of mounting assemblies spaced around the first friction ring and configured to secure the first friction ring to a web of a wheel. At least one of the plurality of mounting assemblies of the first friction ring may include a first arcuate body surrounding a first opening. The brake assembly may also include a second friction ring having a plurality of mounting assemblies spaced around the second friction ring and configured to secure the second friction ring to the web of the wheel. The brake assembly may also include a flexible fastener disposed through the first opening and second opening and configured to be disposed through the web of the wheel to secure the web of the wheel between the first arcuate body and the second arcuate body.
Opening claim text (preview).
What is claimed is: 1 . A method of wheel replacement for a rail vehicle, the method comprising: removing flexible fastener units that secure a web of a first wheel between a first friction ring and a second friction ring, the first friction ring having first mounting assemblies spaced around the first friction ring and configured to secure the first friction ring to the web of the first wheel, wherein at least one of the first mounting assemblies includes a first arcuate body defining a first opening therethrough, the first arcuate body including an arcuate surface surrounding the first opening and curved in an axial direction relative to the first wheel, the arcuate surface of the first arcuate body configured to contact the web of the first wheel, the second friction ring having second mounting assemblies spaced around the second friction ring and configured to secure the second friction ring to the web of the first wheel, wherein at least one of the second mounting assemblies includes a second arcuate body defining a second opening therethrough that corresponds to the first opening; conically deforming the first friction ring; replacing the first wheel with a second wheel after the first friction ring is conically deformed; and securing a web of the second wheel between the first friction ring and the second friction ring. 2 . The method of claim 1 , further comprising: disposing a sliding pin through the web of the second wheel before securing the web of the second wheel between the first friction ring and the second friction ring. 3 . The method of claim 1 , further comprising: deforming elastic elements of at least one of the flexible fastener units before replacing the first wheel with the second wheel. 4 . The method of claim 3 , wherein the elastic elements of the at least one flexible fastener unit are deformed without a fastener body of the at least one flexible fastener unit becoming integrated with the web of the first wheel.
