Abstract
PROCEDIMIENTO DE CONTROL DEL DESARROLLO DE LOS CAMBIOS DE RELACIONES ASCENDENTES SOBRE UNA TRANSMISION AUTOMATICA QUE LLEVA UN CONVERTIDOR DE PAR ASOCIADO A UN ENGRANAJE EPICICLOIDAL MANIOBRADO POR UN CONJUNTO DE RECEPTORES HIDRAULICOS DE MANERA QUE CADA CAMBIO DE RELACION SE OBTENGA PONIENDO BAJO PRESION UN PRIMER RECEPTOR Y DISPARANDO EL VACIADO DE UN SEGUNDO RECEPTOR DURANTE EL PASO DEL REGIMEN TURBINA {OE}T POR UN PUNTO DE DESVIO POSTERIOR A LA PARTE SUPERIOR DE INICIO DE PASO Y ANTERIOR A SU MAXIMO, CARACTERIZADO PORQUE DICHO PUNTO DE DESVIO SE DETECTA COMPARANDO UNA VARIABLE {DL}''DF ASOCIADA AL REGIMEN DE TURBINA CON UN UMBRAL S, CALCULADO DURANTE CADA CAMBIO DE RELACION ASCENDENTE.
