Improved structure, for wheels with brake, characterized by consisting of a fork between whose lateral branches is located a cylindrical wheel equipped with a lateral truncated cone, facing a frustoconical drum, of similar dimensions, which remains immovable by having a key in its larger base that is inserted in the groove or keyway made in the adjacent side of the fork, to practice which has originated an outer flange that serves as support and immobilization to the head of the shaft that passes through the assembly, whose axis has, in its opposite end, of a tightening nut, capable of displacing/the wheel, when being driven, forcing it to fit on the immovable conical drum, so that it is impossible to turn until the nut is loosened and the wheel unlocks by sliding on the conical generatrix of the drum, due to its own weight.
