Abstract (en)

A footboard of a skateboard is with respect to a respective reference plane which at riding straight (= x plane) is parallel to the riding path (= the ground), and at turning (= x'' plane) is with respect to the direction of riding slanted to one or the other side, is rhythmically swung around a longitudinal axis (O) of swinging lying in suspensions (4, 5) of the skateboard. The amplitude (A) and the frequency of swinging are mutually coordinated in a manner that swinging does not result in such meandering of the skateboard, which was felt inconvenient. To a socket shaft housing (8) of a suspension (4, 5) of the skateboard, said housing encasing a roller shaft (11), there is to each end thereof attached a gearing (9, 10), the gearings designed mirror-symmetrically. The gearing (9, 10) is composed of an essentially three-part housing assembly, which comprises a mounting casing (13), an upright intermediate wall (16) and a mounting cover (17), as well as of a train-type gearing composed of a toothed rack (19) as a driving constituent and a gear (25) bound to the roller shaft (11), as a driven constituent. In addition to the roller shaft (11) which passes through, two further, inner shafts (14, 15) constitute said gearing, the lastmentioned shafts each supporting two gears (20, 21; 23, 24), the first one (20) thereof mating the toothed rack (19) and the last one (24) mating the gear (25) driven. The second one (21) of the gears is indirectly connected to the respective shaft (14) by means of an overrunning clutch (22), and shaft (14) is by means of a suitably pre-stressed helical torsion-spring (28), which encompasses the shaft (14), rotationally-elastically bound to the stationary mounting casing (13) of the gearing.
