Title
(EN) TRANSMISSION AND VEHICLE PROVIDED WITH SUCH A TRANSMISSION
(FR) TRANSMISSION ET VÉHICULE POURVU D'UNE TELLE TRANSMISSION
Abstract
(EN)
The invention relates to a transmission comprising two circulating elements and a transmission element, such as a toothed belt. At least one circulating element comprises a number of contact elements for contact with the transmission element which determine a running radius of the transmission element, a radial guide for the contact elements, along which the latter are radially displaceable, displacement means for displacing the contact elements in the radial direction, wherein the transmission element has engagement elements such as teeth. Each of the contact elements comprises a base part which is in contact with the radial guide and with the displacement means, and an engagement member which is connected to the base part and is radially movable with respect to the base part, wherein the engagement member of at least one of the number of contact elements of the respective circulating element is in positive-locking contact with the transmission element.

Transmission comprenant deux éléments de circulation et un élément de transmission, tel qu'une courroie crantée. Au moins un élément de circulation comprend un certain nombre d'éléments de contact pour contact avec l'élément de transmission qui déterminent un rayon de roulement de l'élément de transmission, un guide radial pour les éléments de contact, le long duquel ces derniers peuvent radialement se déplacer, un moyen pour déplacer les éléments de contact dans la direction radial, l'élément de transmission comportant des éléments d'entrée en prise tels que des dents. Chacun des éléments de contact comprend une partie base qui est en contact avec le guide radial et avec le moyen de déplacement, et un élément d'entrée en prise qui est relié à la partie base et qui est mobile radialement par rapport à la partie base, l'élément d'entrée en prise d'au moins un du nombre d'éléments de contact de l'élément de circulation respectif étant en contact de verrouillage positif avec l'élément de transmission.
