A control carrier of each bead is movable over a bolt on a propelled two-wheel swing arm. Position of each individual bead is adjusted and detected over angle sensors, and a vane drive of each individual bead is separately controlled. The swing arm is provided with a separate drive with a motor, clutch, transmission and a drive pinion, where a pivoting angle of each bead is enlarged.
