Abstract
A control device for controlling a transmission ratio between a traction means and a sprocket set rotatable about an axle may include at least two sprockets alternatively wrapped around by the traction means. At least one of the sprockets may include several independently adjustable rim segments. Adjustment of the rim segments in relation to a fixed plane may be effected by a control device in a direction substantially transverse to the plane. The control device includes at least one electrically actuatable control element, e.g., a servomotor. The at least one control element is configured to rotate with the sprockets.
Claims20
A method for controlling a transmission ratio, the method comprising:
- rotating a set of sprockets about an axle using a traction device partially wrapped around the set of sprockets in a fixed plane, wherein a first sprocket of the set of sprockets includes a plurality of independently adjustable sprocket rim segments, and wherein the set of sprockets comprises one or more electrically actuatable control elements coupled to and rotatable with the set of sprockets;
- and
- transferring the traction device between the first sprocket and a second sprocket of the plurality of sprockets by using the one or more electrically actuatable control elements to reposition at least one of the sprocket rim segments in a direction transverse to the fixed plane.
