Title
(EN) DAMPING SYSTEM FOR A RAILWAY TRUCK ASSEMBLY
(FR) SYSTÈME D'AMORTISSEMENT POUR UN ENSEMBLE BOGIE DE CHEMIN DE FER
Abstract
(EN)
A damping system (128) for a truck assembly (100) of a rail vehicle includes a first friction shoe (212a) configured to engage a first portion of a side frame (106, 108) of the truck assembly (100), and a first lever (218) pivotally coupled to the first friction shoe (212a).
(FR)
L'invention concerne un système d'amortissement (128) pour un ensemble bogie (100) d'un véhicule de chemin de fer, lequel système comprend un premier patin de frottement (212a) configuré pour venir en prise avec une première partie d'un châssis latéral (106, 108) de l'ensemble bogie (100), et un premier levier (218) couplé de manière pivotante au premier patin de frottement (212a).
