Claim Text:
1. A control mechanism ( 200 , 300 , 500 , 600 , 660 700 , 800 , 900 ) for setting a transmission ratio between a traction means ( 206 , 309 , 512 , 606 , 706 , 812 . 912 ) and a wheel set that is rotatable about a wheel axle and includes two or more wheel blades ( 202 , 220 , 230 ; 310 , 320 , 330 ; 510 , 520 ; 610 , 620 , 630 ; 710 , 711 , 712 ; 810 , 820 , 830 ) which can facultatively be wrapped around by the traction means, wherein at least one of the wheel blades is composed of a plurality of wheel rim sectors ( wherein the wheel blades have different circumferential radii, another wheel blade ( the control mechanism causes the adjustment of the wheel rim sectors relative to a fixed plane of alignment in a direction substantially transverse to the fixed plane of alignment, the fixed plane of alignment extending along the planar face of the another wheel blade, the control mechanism having wherein the thrust elements are each displaceable in an axial direction between a first position and a second position by couplings of the at least one control component, wherein the couplings are rotation-free in that the couplings do not rotate with the rotary movement of the wheel set, wherein the first position of each thrust element corresponds to an associated wheel rim sector being outside the fixed plane of alignment, whereas the thrust element being in the second position exerts on the associated wheel rim sector, at least as long the associated wheel rim sector is outside the fixed plane of alignment, a force for displacing the associated wheel rim sector into the fixed plane of alignment, the wheel rim sectors are independently adjustable relative to each other via the respectively associated thrust element.
