Title (EN) CONTINUOUSLY VARIABLE TRANSMISSION
(FR) BOITE DE VITESSES A VARIATION CONTINUE
Abstract: front page image
(EN)Continuously variable transmission (1) having a pair of pulleys (2, 3), between which an endless transmission element (10), which is flexible in the longitudinal direction, is rotatably arranged, which pulleys (2, 3) and which transmission element (10) are at least largely made from metal, in which continuously variable transmission at least one of the contact surfaces in a frictional contact between the pulleys (2, 3) and the transmission element (10) is provided with an inorganic surface layer or coating, whereby the said frictional contact takes place without a continuous stream of a liquid lubricant being provided to it.
(FR)L'invention concerne une boîte de vitesses (1) à variation continue comportant deux poulies (2, 3), entre lesquelles est installé rotatif un élément de transmission (10) sans fin, flexible dans le sens de la longueur. Les poulies (2, 3) et l'élément de transmission (10) sont faits au moins en grande partie de métal. Dans cette boîte de vitesses, au moins une des surfaces de contact, en contact par frottement entre les poulies (2, 3) et l'élément de transmission (10), est pourvue d'une couche superficielle ou revêtement inorganique, de sorte que le contact par frottement se fait sans apport continu de lubrifiant liquide.
