Since the toothed segment 9 is rotatably mounted in this case coaxially to the axis A on the power transmission element 4, in which the power transmission element 4 has a raised contact web 4a for the curved toothed segment 9 that guides along it, the spring 10 can again provide a variable distance S this time of the associated tooth flanks 6a, 6b of the teeth 6 on the force transmission element 4 can be set. This in turn compensates for play in the toothing 5, 6, 7 between the output element 3 with the teeth 5 and the internal toothing 5, 6, 7 with the fixed teeth 6 and radially movable teeth 7 on the power transmission element 4.

Abstract

L'invention concerne un entraînement de porte pour une porte de véhicule automobile ou un ouvrant de véhicule automobile, qui est pourvu d'un entraînement par moteur électrique (2), d'une transmission (3) en aval de l'entraînement (2), et d'un élément de transmission de force (4), qui est relié de manière fonctionnelle à un battant (1) de la porte de véhicule automobile ou de l'ouvrant de véhicule automobile. Un élément de sortie (3) de la transmission (3) et l'élément de transmission de force (4) sont couplés par une denture (5, 6, 7) avec compensation du jeu. Selon l'invention, en plus des dents (5, 6) radialement fixes de l'élément de sortie (3) et de l'élément de transmission de force (4), la denture (5, 6, 7) présente également des dents (7) pour la compensation de jeu qui sont disposées coaxialement à au moins l'un des éléments (3, 4) et se déplacent radialement. Les dents (7) radialement mobiles présentent également un décalage angulaire (a) par rapport aux dents (5, 6) radialement fixes.
