  • Patent number: 9499233
    Abstract: A control mechanism (800) for setting a transmission ratio between a traction means (812), in particular chain, and a wheel set that is rotatable about a wheel axle and includes two or more wheel blades (810, 820, 830), in particular sprocket blades, adjusts the wheel rim sectors relative to a fixed plane of the traction means in a direction transverse to the plane of alignment. At least one of the wheel blades is composed of a plurality of independently adjustable wheel rim sectors (802, 803). By means of a control component (807) mounted decoupled from a rotary movement of the wheel set, a plurality of co-rotating thrust elements (804, 805) are each displaced via rotation-free couplings between a first and a second position at least in the axial direction, wherein each of the wheel rim sectors is connected in a rotationally fixed manner to a respectively associated thrust element.
