Abstract

"SISTEMA DE SUSPENSãO ATIVA PARA VEìCULO DETRABALHO Um sistema de suspensão ativa incluinde isoladoresde vibração ativa múltiplos (28, 30, 32) montados entre o chassi (4)e a cabina (6) é discrito. Cada isolador (28, 30, 32) inclui uma racha(44) e um atuador hidráulico (68) conectado entre os suportes (40,42) entre a cabina (6) e o chassi (4). O atuador (44) move a cabina(6) relativa ao chassi (4) quando o fluido hidráulico é seletivamentefornecido ao atuador (68) por um mecanismo de válvularesponsável pelo sinal de controle de válvula. Um primeiro sensorisolador (132) mede o deslocamento entre os suportes, e umsegundo sensor isolador (84) mede o movimento da cabina paraperturbações no chassi (4). Os isoladores múltiplos (28 , 30, 32) sãocontrolados por um circuito de controle comum (200) o qualcontrola o movimento da cabina baseado nos sinais de controlecoordenados.
