Abstract

SE DESCRIBE UN PROCEDIMIENTO PARA EL RETARDO DE UN VEHICULO MIENTRAS SE PRODUCE LA CONMUTACION DE LA DIRECCION DE VIAJE DE SU ENGRANAJE DE VELOCIDADES DE CARGA, DONDE EL MOVIMIENTO DEL VEHICULO SE CONTROLA A PARTIR DE UNA PRIMERA DIRECCION DE VIAJE EN UNA SEGUNDA DIRECCION DE DESPLAZAMIENTO. EL ENGRANAJE DE VELOCIDADES DE CARGA DISPONE DE MULTIPLES ELEMENTOS DE ACOPLAMIENTO ACCIONABLES DE FORMA HIDRAULICA, INCLUYENDO UN CONJUNTO PARA EL ACOPLAMIENTO DE LA DIRECCION DE DESPLAZAMIENTO PARA EL CONTROL DE CONMUTACION DE ESTA DIRECCION. PARA LA DIRECCION SE ABREN PRIMERO TODOS LOS ACOPLAMIENTOS Y A CONTINUACION SE INSTALA UNA PRESION DEL LIQUIDO SOLAMENTE EN UN PRIMER ACOPLAMIENTO (F2) DE DIRECCION DE DESPLAZAMIENTO Y UN SEGUNDO ACOPLAMIENTO (R) DE LA DIRECCION DE VIAJE PARA LA FORMACION DE UN CIERRE DE FUERZA EN EL ENGRANAJE Y PARA LA REDUCCION DE LA VELOCIDAD DE DESPLAZAMIENTO. A CONTINUACION SE APROXIMAN LAS VELOCIDADES DE DESPLAZAMIENTO AL VALOR 0, SE COLOCA EL LIQUIDO DE PRESION EN AL MENOSUN ACOPLAMIENTO ELEGIDO, PARA PERMITIR UN RETROCESO Y UN MOVIMIENTO DEL VEHICULO EN LA SEGUNDA DIRECCION DE VIAJE EN UNA MARCHA DESEADA. FINALMENTE SE ABRE EL PRIMER ACOPLAMIENTO (F2) DE DIRECCION DE VIAJE, PARA LEVANTAR EL EFECTO DE FRENADO.
