Abstract
(DE)
Die Erfindung betrifft ein Schiebenockensystem für eine Brennkraftmaschine mit wenigstens einer Nockenwelle (10) umfassend eine Trägerwelle (11) mit wenigstens zwei Schiebenockenelementen (12a, 12b), die jeweils eine Schaltkulisse (13) mit wenigstens einer Schaltnut (14) umfassen, wobei die Schiebenockenelemente (12a, 12b) durch wenigstens einen Aktuator-Pin (15) axial zur Trägerwelle (11) verschiebbar sind und wenigstens ein Verstellelement (16) parallel zu einer Längsachse der Trägerwelle (11) angeordnet ist, wobei das Verstellelement (16) in Richtung der Längsachse der Trägerwelle (11) axial verschiebbar ist. Das Schiebenockensystem zeichnet sich dadurch aus, dass das Verstellelement (16) wenigstens zwei Kopplungs-Pins (17a, 17b) aufweist, wobei ein erster Kopplungs-Pin (17a) im Bereich des ersten Schiebenockenelements (12a) angeordnet ist und ein zweiter Kopplungs-Pin (17b) im Bereich des zweiten Schiebenockenelements (12b) angeordnet ist und die Kopplungs-Pins (17a, 17b) jeweils mit einer Schaltkulisse (13) des jeweils zugehörigen Schiebenockenelements (12a, 12b) Zusammenwirken derart, dass durch das Verstellelement (16) eine durch den Aktuator-Pin (15) eingeleitete Bewegung des ersten Schiebenockenelements (12a) auf das zweite Schiebenockenelement (12b) übertragbar ist.
(EN)
The invention relates to a slide cam system for an internal combustion engine having at least one camshaft (10) comprising a carrier shaft (11) having at least two slide cam elements (12a, 12b), each comprising a shifting gate (13) having at least one switch groove (14), wherein the slide cam elements (12a, 12b) are axially movable relative to the carrier shaft (11) by means of at least one actuator pin (15) and at least one adjustment element (16) is arranged parallel to a longitudinal axis of the carrier shaft (11), wherein the adjustment element (16) is axially movable in the direction of the longitudinal axis of the carrier shaft (11). The slide cam system is characterized in that the adjustment element (16) has at least two coupling pins (17a, 17b), wherein a first coupling pin (17a) is arranged in the region of the first slide cam element (12a) and a second coupling pin (17b) is arranged in the region of the second slide cam element (12b) and each coupling pin (17a, 17b) interacts with a shifting gate (13) of the relevant associated slide cam element (12a, 12b) such that a movement of the first slide cam element (12a), initiated by the actuator pin (15), is transmittable to the second slide cam element (12b) by the adjustment element (16).

L'invention concerne un système de cames coulissantes pour un moteur à combustion interne doté d'au moins un arbre à cames (10) comprenant un arbre porteur (11) doté d'au moins deux éléments de cames coulissantes (12a, 12b) qui comprennent respectivement une coulisse de commande (13) dotée d'au moins une rainure de commande (14). Les éléments de cames coulissantes (12a, 12b) peuvent être déplacés axialement par rapport à l'arbre porteur (11) au moyen d'au moins une broche d'actionnement (15) et au moins un élément de réglage (16) est disposé parallèlement à l'axe longitudinal de l'arbre porteur. Ledit élément de réglage (16) peut être déplacé axialement dans le sens de l'axe longitudinal de l'arbre porteur (11). Le système de cames coulissantes se caractérise en ce que l'élément de réglage (16) présente au moins deux broches d'accouplement (17a, 17b). Une première broche d'accouplement (17a) est disposée dans la zone du premier élément de cames coulissantes (12a) et une deuxième broche d'accouplement (17b) est disposée dans la zone du deuxième élément de cames coulissantes (12b). Les broches d'accouplement (17a, 17b) coopèrent chacune avec une coulisse de commande (13) de l'élément de cames coulissantes correspondant (12a, 12b) de manière à ce qu'un mouvement du premier élément de cames coulissantes (12a), initié par la broche d'actionnement, (15) peut être transmis au deuxième élément de cames coulissantes (12b) au moyen de l'élément de réglage (16).
