Abstract: 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.

Abstract: A continuously variable transmission including a first pulley means, a second pulley means and an elongate, flexible endless transmission element that is passed over both the first pulley means and the second pulley means, wherein the first pulley means include two sheaves which are adjustable in an axial direction of the first rotation axis line, and an adjusting means for moving the two adjustable sheaves toward and away from each other in the axial direction for setting an operative radius of the first pulley means at which the transmission element is passed over the first pulley means, wherein the first pulley means is provided with alignment means for causing the two movable sheaves to jointly move additionally in the axial direction of the first rotation axis under the influence of a force exerted in axial direction on the first pulley means by the transmission element while maintaining the operative radius.
