Title
(DE) VERTEILEREINSPRITZPUMPE MIT VORGESPANNTEM KRAFTÜBERTRAGUNGSELEMENT
(EN) DISTRIBUTOR INJECTION PUMP COMPRISING A PRETENSIONED FORCE TRANSMISSION ELEMENT
(FR) POMPE D'INJECTION A DISTRIBUTEUR POURVUE D'UN ELEMENT DE TRANSMISSION DE FORCE PRECONTRAINT
Abstract
(DE) Die Erfindung bezieht sich auf ein Förderaggregat eines zur Versorgung der Kraftstoffeinspritzanlage einer selbstzündenden Verbrennungslkraftmaschine. Das Förderaggregat (1) umfasst eine Antriebswelle (3), an deren Stirnseite (5, 40) klauenförmige Vorsprünge (6) vorgesehen sind, die in Ausnehmungen (7.1) eines Kraftübertragungselementes (7) eingreifen und eine verdrehbare Hubscheibe (9), an deren Stirnseite (10) klauenförmige Vorsprünge (57) ausgebildet sind, die in zu diesen korrespondierenden Ausnehmungen (57.1) am Kraftübertragungselement (7) eintauchen. Das Kraftübertragungselement (7) ist an der Stirnseite (40) der Antriebswelle 3, durch ein Vorspannelement (46) beaufschlagt, gelenkig gelagert
(EN) The invention relates to a delivery unit for supplying the fuel injection system of an auto-ignition internal combustion engine. The delivery unit (1) comprises a drive shaft (3) on whose face (5, 40) claw-shaped projections (6) are provided that engage inside recesses (7.1) of a force transmission element (7), and comprises a rotating lifting disk (9) on whose face (10) claw-shaped projections (57) are provided that extend into corresponding recesses (57.1) on the force transmission element (7). The force transmission element (7) is mounted in an articulated manner on the face (40) of the drive shaft (3) while being acted upon by a pretensioning element (46).
(FR) L'invention concerne une unité d'alimentation conçue pour le dispositif d'injection de carburant d'un moteur à combustion interne à autoallumage. Cette unité d'alimentation (1) comprend un arbre de commande (3) pourvu, sur sa face (5, 40), d'éléments saillants crochus (6) s'engageant dans des évidements (7.1) ménagés dans un élément de transmission de force (7), ainsi qu'un disque à came rotatif (9) pourvu, sur sa face (10), d'éléments saillants crochus (57) s'engageant dans des évidements (57.1) correspondants, au niveau de l'élément de transmission de force (7). Cet élément de transmission de force (7) est logé sur la face (40) de l'arbre de commande (3) de manière articulée et de façon à être soumis à un élément de précontrainte (46).
