Title (EN) REDUCTION OF THE THERMAL STRESS OF STARTING SWITCH ELEMENTS IN AUTOMATIC GEARBOXES OR IN AUTOMATED MANUAL GEARBOXES
(FR) REDUCTION DE LA SOLLICITATION THERMIQUE D'ELEMENTS DE COMMANDE DE DEMARRAGE DANS DES BOITES DE VITESSES AUTOMATIQUES OU DES BOITES DE VITESSES A COMMANDE MANUELLE AUTOMATISEES
(DE) REDUZIERUNG DER THERMISCHEN BELASTUNG VON ANFAHRSCHALTELEMENTEN BEI AUTOMATGETRIEBEN ODER AUTOMATISIERTEN HANDSCHALTGETRIEBEN
Abstract:
(EN) The invention relates to a method for reducing the thermal stress of starting switch elements in automatic gearboxes or automated manual gearboxes, comprising at least two switch elements situated in the power train. Within the framework of said method, at the moment of ignition, at least one other switch element is used along with a first switch element, in order to take on at least one part of the slip capacity.
(FR) L'invention concerne un procédé permettant de réduire la sollicitation thermique d'éléments de commande de démarrage de boîtes de vitesses automatiques ou de boîtes de vitesses à commande manuelle automatisées, comportant au moins deux éléments de commande situés dans la chaîne cinématique. Dans le cadre de ce procédé, au moment du démarrage, il est prévu d'utiliser en plus d'un premier élément de commande, un autre élément de commande, afin de prendre en charge au moins une partie de la capacité de patinage.
(DE) Im Rahmen des Verfahrens zur Reduzierung der thermischen Belastung von Anfahrschaltelementen bei Automatgetrieben oder automatisierten Handschaltgetrieben mit mindestens zwei im Kraftfluss liegenden Schaltelementen wird beim Anfahren neben einem ersten Schaltelement mindestens ein weiteres Schaltelement eingesetzt, um zumindest einen Teil der Schlupfleistung zu übernehmen.
