Abstract

UN APARATO DE EMBRAGUE PROPULSOR PARA UN VEHICULO DE TRABAJO, QUE COMPRENDE UN EMBRAGUE HIDRAULICO DE TIPO DE FRICCION MONTADO SOBRE UNA LINEA DE PROPULSION, UNA VALVULA PARA AJUSTAR UNA PRESION DE ACEITE APLICADA AL EMBRAGUE HIDRAULICO, UN SENSOR PARA DETECTAR LA ACELERACION ANGULAR DE UN ARBOL GIRATORIO INCLUIDO EN LA LINEA DE PROPULSION, Y UNA UNIDAD DE CONTROL PARA CONTROLAR EL EMBRAGUE HIDRAULICO EN RESPUESTA A UN CAMBIO EN EL ESTADO DE MARCHA DEL VEHICULO. LA UNIDAD DE CONTROL EFECTUA EL CONTROL EN TRES FASES. LA PRIMERA FASE INCLUYE UN PASO PRELIMINAR DE ESTRECHAMIENTO DE LOS ESPACIOS ENTRE LOS DISCOS DE FRICCION DEL EMBRAGUE HIDRAULICO, LA SEGUNDA ES PARA MANTENER EL EMBRAGUE HIDRAULICO EN ESTADO DE MEDIO EMBRAGUE Y LA TERCERA FASE ES PARA EL ACOPLAMIENTO TOTAL DEL EMBRAGUE HIDRAULICO.
