Title
(EN) A VARIABLE SPEED DRIVE
(FR) VARIATEUR DE VITESSE
Abstract
(EN) A variable speed drive comprising two drives A and B, an output drive wheel (62) and an endless, extendible member (66) that is driven by the drive A and B and extends round and rotates the output drive wheel (62). The drives A and B are operable to move the endless member (66) around an endless path at a first speed at a first driving position and at a second speed at a second position. This causes local expansion or contraction of the endless member (66) round the output drive wheel (62) and so varies its speed.
(FR) L'invention concerne un variateur de vitesse composé de deux mécanismes d'entraînement A et B, d'une roue motrice de sortie (62) et d'un élément sans fin extensible (66) qui est entraîné par les mécanismes d'entraînement A et B, qui s'enroule autour de la roue motrice de sortie (62) et qui la fait tourner. Les mécanismes d'entraînement A et B permettent à l'élément sans fin (66) de se déplacer le long d'un trajet sans fin à une première vitesse et dans une première position d'entraînement ainsi qu'à une seconde vitesse et dans une seconde position. De cette manière, l'élément sans fin (66) s'étend ou se contracte localement autour de la roue motrice de sortie (62), ce qui a pour effet de varier la vitesse de celle-ci.
