(2) FIG. 2 shows a perspective and detail view of the support (114) of the wheel straightener device (100).

(3) FIGS. 3A, 3B, 3C show possible embodiments for the backrest (114) of the wheel straightener device (100).

(4) FIGS. 4 and 5 show the constructive arrangement of the flange, part of the equipment where the wheel to be straightened fixed.

(5) In allusion to the figures shown, said wheel-making device (100), according to FIG. 1, comprises main column (110), wherein at one of its ends, it has a wheel fixing flange (111) to be corrected, and at another end, has a fixing base (112) for the assembly; in its central portion, said main column (110) has a tubular extension (113), perpendicular to said main column (110), where a smaller second tubular extension (120) engages therein, forming a telescopic joint at the other end of said second tubular extension (120), a part (121) is provided to engage a third tube segment, which is the column (132) of the piston (130), which is positioned at the upper end of said column (132).

(6) Said column (132) of the piston (130) is positioned perpendicular to the second extension (120) and parallel to the primary column (110); said column (132) of the piston (130) has means for height adjustment, which can be bores (131) which pins are inserted; and at the other end provides means for the attachment of the hydraulic piston (130), including a type of hinged attachment, so as to allow angulation thereof.

(7) At the top of the main column (110), there is provided a support (114) suitably shaped to support the opposite end of the straightening wheel is desired, i.e., end opposite to that which is in contact with the piston (130); FIG. 2 illustrates the support (114) in detail. Said support (114) is mounted on a body (115), forming a single piece; the support (114) and the body (115) can now be manufactured in a single piece, or may be separate and attachable parts together; in this case the body (115) and the support (114) should provide means to be engaged with each other. Said body (115) may have height adjustment which can be by means of spindle, telescopic or articulated arm; and said body (115) is mounted on a guide (118), wherein both the body (115) and the guide (118) have constructive and socket configuration allowing the displacement of said support (114) on the guide (118) to approach or move away from the positioned wheel on the flange (111); this displacement is necessary for better support of the wheel, of different widths; said body (115) of the support (114) provides means for being locked to the guide (118) after properly positioned; such fixing may be by the body of the spindle itself (115), if their format is a time can be by means of pins and holes, arranged on the body base (115) and the guide (118), or other compatible similar solution. Also, the rear support region (114) is provided for one measuring rod (116) that serves as a template for locating imperfections in the wheel that is to be corrected.

(8) A hydraulic pump (117) is also provided connected by hoses (119) to the hydraulic piston (130), so as to drive said piston (130), said pump (117) is preferably laid out in the central region on the side of the main column (110), and thus provides a more ergonomic position for the operator to operate manually.

(9) FIGS. 3A, 3B and 3C illustrate different geometric shapes of supports (114), which can be useful to support different wheel shapes such as a flattened formed (FIG. 3A) or a more concave shape (FIG. 3B), or with chamfer recess (FIG. 3C). Other different formats may be possible for this support (114).

(10) The flange configuration (111) is also specific and is illustrated in isolation in FIGS. 4 and 5. As shown in figures, said flange (111) has a central hole for attachment in the machine, and a set of oblong holes radial, which are arranged in three sequences from a reference hole (I, II, III), as illustrated in FIG. 4. from this reference hole (I, II, III) are arranged following a first radial elongated holes (I) spaced at 72; a second sequence of radial elongated holes (II) spaced at 90; and a third sequence of radial elongated holes (III) spaced at 120. Said flange (111) has a preferred dimension in the range of 210 mm diameter, and the slots having a width of 13.50 mm width and length between the centers 40 to 42 mm range, however other dimensions descaracterizando not fall within the scope of the object of the present patent application. This configuration of holes in the flange (111) allows a universality of the equipment for the fixation of different wheels, with 3, 4, 5 and 6 holes and of different configurations of drillings, simply adjusting the fastening elements (screws) along the holes of the flange.

(11) The operation of the wheel straightening device occurs as follows: the operator positions and secures the wheel to the flange (111) of the wheel, the end of the main column (110) then checks which wheel points to be corrected, using the measuring rod (116) as the operator manually rotates the wheel, the end of the measuring rod (116) locks at points that are higher and does not touch the points and is low, so the operator can mark the points to be demeaned. The next step is to position the tip of the piston rod (130) hydraulic, the mark made previously, pumping the hydraulic pump (117), and continue applying force to the wheel geometry is fixed, then releases the pressure, and the process is repeated for the following marks. By doing this it is possible to meet the largest number of wheels available in the market, and perform wheel correction quickly without generating wheel twisting problems.

(12) Said equipment can provide varying dimensions, including its flange (111), as well as varied geometric support format (114), but within this same inventive concept and within the scope proposed in this report. In this way, such variations should not be understood as a de-characterization of the object presented and described in this document.
