(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 elementsfor 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 theengagement 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.
(ZH) 本发明涉及一种变速器，其包括两个循环元件和诸如齿形带的传动元件。至少一个循环元件包括：多个接触元件，其用于与传动元件接触，多个接触元件确定传动元件的运行半径；径向引导件，其用于接触元件，接触元件可以沿着径向引导件径向移位；移位部件，其用于使接触元件在径向上移位，其中传动元件具有诸如齿的接合元件。各接触元件包括：基部，其与径向引导件和移位部件接触；和接合构件，其连接到基部并且可以相对于基部径向移动，其中相应的循环元件的多个接触元件中的至少一者的接合构件与传动元件形状锁定接触。
