Abstract

"SISTEMA DE CONTROLE PARA CONTROLAR A VELOCIDADE DE UM MOTOR DE DIREçãO EM RESPOSTA à MANIPULAçãO DE UM ELEMENTO DE ENTRADA DE DIREçãO EM UM VEìCULO DE ESTEIRAS". Um veículo de esteiras inclui uma bomba de direção de deslocamento variável acionada por motor que aciona um motor hidráulico de direção. O motor de direção aciona um mecanismo de acionamento diferencial que aciona rodas de acionamento de esteiras esquerda e direita. Um sistema de controle de direção sensorea a posição de uma roda de direção não centrada por mola, a velocidade do veículo, a velocidade do motor, a velocidade do motor de direção, se ou não a transmissão está em engrenada ou em neutro, e se a embreagem esta engatada ou desengatada. Para impedir uma situação de giro auto-perpetuador, o sistema de controle gradualmente reduz a velocidade do motor de direção se a transmissão está em neutro ou se a embreagem não está engatada, e se a velocidade do motor de direção dividida pela velocidade do veículo é maior que um limiar, e se a velocidade do veículo é menor que um nível de referencia.
