Title
(EN) TRANSMISSION ELEMENT AND TRANSMISSION PROVIDED WITH SUCH A TRANSMISSION ELEMENT
(FR) ÉLÉMENT DE TRANSMISSION ET TRANSMISSION DOTÉE D'UN TEL ÉLÉMENT DE TRANSMISSION
Abstract
(EN)
The invention relates to a transmission element for a transmission such as a continuously variable transmission, comprising an elongate flexible endless carrier element provided with a number of receiving spaces with an opening and with a passage extending through the number of receiving spaces in the longitudinal direction of the carrier element, a number of engaging elements which are each received in a receiving space for movement between an active position and a passive position and which in the active position protrude further inward than in the passive position and at least out of the opening of this receiving space so as to be able to engage in the active position with a pulley of the transmission, and a spring element for providing resistance for each of the number of engaging elements during movement from the active position in the direction of the passive position.
(FR)
Cette invention concerne un élément de transmission pour une transmission telle qu'une transmission variable en continu, comprenant un élément de support sans fin flexible allongé pourvu d'un certain nombre d'espaces de réception avec une ouverture et avec un passage s'étendant à travers lesdits espaces de réception dans la direction longitudinale de l'élément de support, un certain nombre d'éléments de mise en prise accueillis dans un espace de réception pour un déplacement entre une position active et une position passive et qui, dans la position active, font saillie plus loin vers l'intérieur que dans la position passive, et au moins en dehors de l'ouverture de l'espace de réception de façon à être aptes à venir en prise dans la position active avec une poulie de la transmission, et un élément à ressort pour fournir une résistance pour chacun desdits éléments de mise en prise pendant le déplacement à partir de la position active dans la direction de la position passive.
