Title (EN) VARIABLE CAMSHAFT CONTROL MEANS
(FR) COMMANDE D'ARBRE À CAMES VARIABLE
(DE) VARIABLE NOCKENWELLENSTEUERUNG
Abstract:
(EN) The invention relates to a variable camshaft control means (10) having an externally toothed camshaft (12), an internally toothed cam part (14), wherein the cam part (14) is mounted axially displaceably on the camshaft (12), an intermediate space (22) which is arranged between the camshaft (12) and the cam part (14) in a region of an external toothing system of the camshaft (12) and an internal toothing system of the cam part (14), and a lubricant feed device (20) for guiding lubricant into the intermediate space (22). Here, the lubricant feed device (20) has a passage (16a, 16b, 16c, 16d) which extends through the cam part (14), wherein the passage (16a, 16b, 16c, 16d) begins in a lubricant collecting region (18) for mounting the cam part (14) and ends in the intermediate space (22).
(FR) La présente invention concerne une commande d'arbre à cames variable (10) comprenant un arbre à cames (12) à denture extérieure, une pièce à cames (14) à denture intérieure, la pièce à cames (14) étant agencée sur l'arbre à cames (12) de façon à pouvoir se déplacer axialement, un espace intermédiaire (22) qui est formé entre l'arbre à cames (12) et la pièce à cames (14) dans une zone d'une denture extérieure de l'arbre à cames (12) et d'une denture intérieure de la pièce à cames (14), et un dispositif d’apport de lubrifiant (20) pour amener du lubrifiant dans l'espace intermédiaire (22). Selon l’invention, le dispositif d’apport de lubrifiant (20) présente un passage (16a, 16b, 16c, 16d) qui s’étend à travers la pièce à cames (14), le passage (16a, 16b, 16c, 16d) commençant dans une zone d’accumulation de lubrifiant (18) pour le logement de la pièce à cames (14) et se terminant dans l’espace intermédiaire (22).
(DE) Die Erfindung betrifft eine variable Nockenwellensteuerung (10) mit einer außenverzahnten Nockenwelle (12), einem innenverzahnten Nockenstück (14), wobei das Nockenstück (14) axial verschieblich auf der Nockenwelle (12) gelagert ist, einem Zwischenraum (22), welcher zwischen der Nockenwelle (12) und dem Nockenstück (14) in einem Bereich einer Außenverzahnung der Nockenwelle (12) und einer Innenverzahnung des Nockenstücks (14) angeordnet ist, und einer Schmierstoffzuführeinrichtung (20) zum Führen von Schmierstoff in den Zwischenraum (22). Dabei weist die Schmierstoffzuführeinrichtung (20) einen sich durch das Nockenstück (14) erstreckenden Durchgang (16a, 16b, 16c, 16d) auf, wobei der Durchgang (16a, 16b, 16c, 16d) in einem Schmiermittelsammelbereich (18) zur Lagerung des Nockenstücks (14) beginnt und in dem Zwischenraum (22) endet.
