Title (EN) MACHINE CONFIGURATIONS EMPLOYING PASSIVE AND CONTROLLABLE CAB MOUNTS
(FR) CONFIGURATIONS D'ENGIN EMPLOYANT DES SUPPORTS DE CABINE PASSIFS ET PILOTABLES
Abstract:
(EN) A machine (100) includes a frame (102) and an operator cab (104) supported by the frame (102). One or more passive mounts (312) and one or more controllable mounts (106) operatively connect the operator cab (104) to the frame (102). The one or more controllable mounts (106) include a housing (108), a pin (120) mounted within the housing (108), a rheological fluid (116) within the housing (108), and coils (131) positioned relative to the housing to generate a field through the rheological fluid (116). An electronic control unit (168) operatively associated with the coils (131) and adapted to change a level of current applied to the coils (131) to adjust an apparent viscosity of the rheological fluid (116) to actively change the damping characteristics of the one or more controllable mounts ( 106).
(FR) L'invention concerne un engin (100) comprenant un châssis (102) et une cabine (104) d'opérateur portée par le châssis (102). Un ou plusieurs supports passifs (312) et un ou plusieurs supports pilotables (106) relient fonctionnellement la cabine (104) d'opérateur au châssis (102). Le ou les supports pilotables (106) comprennent une enveloppe (108), un axe (120) monté à l'intérieur de l'enveloppe (108), un fluide rhéologique (116) à l'intérieur de l'enveloppe (108) et des bobines (131) positionnées par rapport à l'enveloppe en vue de générer un champ à travers le fluide rhéologique (116). Une unité électronique (168) de commande est associée fonctionnellement aux bobines (131) et prévue pour modifier un niveau de courant appliqué aux bobines (131) afin de régler une viscosité apparente du fluide rhéologique (116) en vue de modifier activement les caractéristiques d'amortissement du ou des supports pilotables (106).
