Abstract

uma disposição para carregamento de um acumulador a presente invenção se refere a uma disposição para carregamento de um acumulador (10) com fluido hidraúlico. o acumulador (10 é utilizado em um sistema de suspensão de lança (longarina, haste, extensão) hidraúlica (3) para um braço de elevação (55) de um veículo (50) e a disposição compreende uma primeira bomba hidraúlica (4) disposta para suprir fluido hidraúlico para um sistema de cilindro hidraúlico (2) do braço de elevação (55), e uma segunda bomba hidraúlica (5) disposta para suprir fluido hidraúlico para um segundo sistema hidraúlico. a segunda bomba hidraúlica (5) é adicionalmente disposta para suprir fluido hidraúlico para carregamento do acumulador (10). em concordancia com a presente invenção, a disposição compreende uma primeira função de carregamento adaptada para carregar o acumulador para uma primeira pressão por incremento da pressão em concordância com uma função de incremento de pressão pré-definida quando o sistema de suspensão de lança é desativado e uma segunda função de carrgamento adaptada para carregar o acumulador para uma segunda pressão por incremento adicionalmente da pressão em concordância com uma segunda função de incremento de pressão pré-definida para um nível que é substancialmente igual para a pressão de carga corrente no sistema de cilindro hidraúlico de braço de elevação quando um sinal de controle indica que o sistema de suspensão lança é para ser ativado.
