Abstract

"SISTEMA DE SUSPENSãO PARA UM TRUQUE FERROVIáRIO E MéTODO PARA AJUSTAR UMA SUSPENSãO DE MOLAS DE UM TRUQUE FERROVIáRIO". Um grupo de molas ajustado com molas de carga, molas de controle, e um arranjo de amortecimento de fricção para uma montagem de truque de vagão ferroviário provê melhor qualidade de viagem, resistência aumentada a assentamento de suspensão, e velocidade de limiar de oscilação aumentada de um vagão ferroviário. Especificamente, este arranjo de suspensão e amortecimento ajustado provê uma capacidade de reserva de grupo de molas de menos que 1,50. Montagens de molas para tipos de vagão diferentes são ajustadas, tal que uma razão de reserva menos de 1,50 possa ser alcançada. Reduzindo a capacidade de reserva de montagem de molas para um vagão e truque de um peso padrão e configuração a menos de 1,50, um resultado inesperado de uma diminuição em aceleração vertical máxima quando a montagem de truque de vagão chega a uma velocidade de 88,5 km/h e alcançado. A diminuição em aceleração vertical permite qualidade de viagem melhorada, resistência aumentada a assentamento de suspensão e velocidade de limiar de oscilação aumentada do vagão.
