Title (EN) IMPROVED DOLLY SYSTEM
(FR) SYSTÈME DE CHARIOT AMÉLIORÉ
Abstract: front page image
(EN)A dolly system is disclosed, which overcomes drawbacks related to unwanted noise and jerks of prior art dolly systems. The dolly system comprises wheel assemblies (130) that have independently rotating lateral support wheels (132, 133) in combination with a center wheel (131) that interact with a continuous resilient element (122) when rolling along a rail track, without encountering any gaps or bumps and without producing squeal noise due to so-called wheel-climbing that may occur in curves along the rail track.
(FR)L'invention concerne un système de chariot qui surmonte les inconvénients liés au bruit et aux secousses indésirables des systèmes de chariots selon la technique antérieure. Le système de chariot comporte des ensembles roues (130) dotés de roues porteuses latérales (132, 133) tournant indépendamment en combinaison avec une roue centrale (131), qui interagissent avec un élément élastique continu (122) lors du roulement le long d'une voie ferrée, sans rencontrer aucun interstice ou aucune bosse et sans produire un bruit de grincement dû au phénomène dit d'ascension des roues qui peut survenir dans les courbes le long de la voie ferrée.
