“INLINE SKATEBOARD WITH DIFFERENTIATED WHEELS’ that has wheels with different predetermined sizes being affixed by means of two trucks to the shape. Besides the wheels, the two trucks have a shock absorber device, a metallic base structure and a torsion system for the execution of curves with the automatic alignment of the wheel sets with the shape after turning movement completion. Thus, the movement is limited by three features combined: the size of the internal wheels, the sliding of the internal screw through the aperture of the wheels axles' fixation support and the sliding of the intermediary parts of the recesses of the torsion device mortise aperture with the wheels axles' fixation support relative to the sleeve apertures.

1. An inline skateboard comprising an elongated shape extending along a longitudinal axis; anda pair of trucks each rotatably attached to the shape and substantially aligned with one another along the longitudinal axis;wherein each truck comprises: a support;one internal wheel rotatably supported by the support; andone external wheel rotatably supported by the support and in alignment with the internal wheel substantially along the longitudinal axis;wherein a width of the internal wheel is greater than a width of the external wheel and a maximum radius of the internal wheel is equal to a maximum radius of the external wheel. 2. The skateboard according to claim 1, wherein the internal wheel has a profile defined by a constant radius and the external wheel has a profile defined by a radius that decreases from a center to an outer edge. 3. The skateboard according to claim 1, wherein each of the trucks is rotatable to each side of the longitudinal axis up to a predetermined angle. 4. The skateboard according to claim 3, wherein the predetermined angle is an angle between 3 degrees and 9 degrees. 5. The skateboard according to claim 1, further comprising a plurality of absorber devices disposed between each of the trucks and the shape. 6. The skateboard according to claim 1, further comprising a torsion device comprising an elastic member that is attached to the shape at least at a center thereof and that includes a fastening aperture that engages a projection on the support; wherein each of the trucks is rotatable relative to the shape about the center of the elastic member. 7. The skateboard according to claim 6, further comprising a fixation base attaching each of the trucks to the shape. 8. The skateboard according to claim 7, wherein the fixation base further comprises: a plurality of torsion deformation apertures to alleviate deformation of the torsion device. 9. The skateboard according to claim 6, further comprising a sleeve disposed over the torsion device and including a pair of apertures diametrically opposed to one another whereby screws are passed through; rotation movement limiting apertures, and two protrusions diametrically opposed and in the same direction as the screws apertures. 10. The skateboard according to claim 9, further comprising a fastener that extends through the torsion device and the sleeve, and attaches each of the trucks to the shape. 11. The skateboard according to claim 1, further comprising an axle supporting each of the wheels on the respective support, wherein: the support of each of the trucks comprises a metal sheet that includes two side walls and one central surface extending between the two side walls; andeach of the side walls including a plurality of axle pass-through apertures. 12. The skateboard of claim 11, wherein the metal sheet includes weight reduction openings distributed on areas susceptible to lower forces during the use of the skate and positioned at a distance away from the axle pass through apertures. 13. The skateboard of claim 11, wherein the axle pass-through apertures on one of the side walls of each truck are approximately elliptical, and the axle pass-through apertures on the other of the side walls are circular. 14. The skateboard according to claim 11, wherein one end of each of the axles has a circular edge and the other end of each of the axles has a chamfered edge. 15. The skateboard according to claim 1, further comprising: an axle supporting each of the wheels on the respective support; anda pair of bearings attaching each of the wheels to the respective axle. 16. The skateboard according to claim 1, further comprising a movement limiting aperture that limits the angle of rotation of each of the trucks. 17. The skateboard according to claim 16, wherein the angle of rotation of each of the trucks is limited by the width of the internal wheels and a length of the support movement limiting aperture. 18. The skateboard according to claim 1, wherein a difference between the width of the internal wheels and the width of the external wheels is equal to a distance that the internal wheels are movable in a direction perpendicular to the longitudinal axis when the truck rotates.
