Vehicle propelled by
muscle power, in particular scooter, with at least one driving wheel and at least one
tread surface (5, 5′) which is movable via a
tread surface
stroke, wherein the force transmission from the at least one
tread surface (5, 5′) to the at least one driving wheel takes place by means of a driving element (6, 6′) which is guided with a nonpositive fir via a
drive shaft (8, 8′) which is coupled to the driving wheel via a freewheeling mechanism, wherein the
drive shaft (8, 8′) and / or preferably at least one deflecting roller (7, 7′) is / are divided into at least two axial regions (7b, 7c; 7b′, 7c′, 8a, 8b; 8a′; 8b′) with radii which differ from one another or are variable, and the driving element (6, 6′) is divided into partial sections with different cross sections which are designed in such a manner that the partial sections (6a, 6b 6c; 6a′, 6b′ 6c′) of the driving element (6, 6′) are guided within the tread surface
stroke (O-U) on the respectively corresponding axial region of the
drive shaft (8, 8″) and / or deflecting roller (7, 7′). As a result, the overall
transmission ratio (uges) of the vehicle can be configured within the tread surface
stroke (O-U) within wide limits, wherein, in particular, the drive shaft (8, 8′) which is designed according to the invention can undertake a plurality of revolutions without colliding with a driving element.
