Abstract

uma mola pneumática com características de amortecimento para um conjunto de suspensão de um veículo de serviço pesado inclui um fole e um pistão. o fole inclui uma câmara de fole. o fole está fixado a um membro principal do veículo de serviço pesado e ao pistão. o pistão inclui uma parte inferior aberta que é fechada de modo vedante por um disco fixado à parte inferior aberta. o pistão e o disco definem uma câmara de pistão. o pistão está montado sobre o conjunto de suspensão do veículo de serviço pesado. a câmara de fole e a câmara de pistão estão em comunicação fluida uma com a outra por meio de pelo menos uma abertura, em que o fluxo de ar entre a câmara de fole e a câmara de pistão fornece amortecimento para o conjunto de suspensão do veículo de serviço pesado.
