A method is also disclosed.
Description
- The present invention relates to an apparatus for re-truing or restoring the centering of tire rims.
- The increasingly widespread use of alloy rims as a standard fitting on motor vehicles, as well as parts designed for special optional applications and the usual tendency to combine them with tyres commonly known as “low profile tyres”, has highlighted the evident problem of deformation of the rim well following occasional impacts-against obstacles such as pavements, stones, holes and the like, should the resilience of the tyre not be sufficient to absorb the entire force thereof. Until a short time ago the damage was repaired by means of essentially manual operations, hammering the damaged rim part, with consequent dents and approximate centering. Some highly specialized operators in the sector use the lathe for this kind of repair, nevertheless with obvious limitations in terms of centering and in many cases resulting in structural damage to the rim such that suitable and safe operation thereof cannot be ensured. Others use hydraulic presses which are suitably equipped to “remould” the circular form of the rim in the hot state (deep-drawing), with consequent alteration of the structure of the material from which the rim is made and possible alteration of the original measurements of the rim due to elongation stress-relief caused by heating and subsequent pressure exerted by the device operated by the press.
- The document EP-A-1424145 describes an apparatus for re-centering the rims for tyres, comprising: a rod, which can be connected to a suitable support, can be inserted inside the hole for engaging a rim with the hub of a wheel and provided with means for locking, coaxial with the said rod, the plate of the said rim, so as to position said rod along the direction of the axis of said rim; thruster means able to act in any direction perpendicular to the said rod, movable along the latter and provided with means for adjusting and fixing their position along the said rod.
- With the apparatus described above, owing to its constructional and geometrical characteristics in relation to coupling with the rim, it was possible to verify perfectly the degree of concentricity of the rim with respect to its axis, providing a clear indication, by means of a quantitative analysis performed by the user during the various stages of re-centering. This was performed by means of “comparison” namely by means of frictional contact between two bodies coaxially rotating relative to each offer. Therefore the degree of accuracy of the repair could be guaranteed 100%, but was still dependent upon the user.
- Moreover, determining the appropriate thrusting force to be applied was complex; in this connection, it was thought to use a wheel balancing apparatus of the known type and commercially available in order to verify the degree of deformation and consequently determine quantitatively the degree of accuracy during the successive stages of repair. In this case, however, carrying out checks whenever a single thrusting force was applied to the rim meant that a considerable amount of time was lost.
- The object of the present invention, therefore, is to provide an apparatus which is able to make the rim repair operations more precise and easier, allowing an analytical evaluation of the degree of damage during all the stages of re-centering and an accurate check as to the force applied.
- The present invention therefore relates to an apparatus for restoring the centering of tire rims, comprising: a rod which can be inserted into the centring hole for engaging a rim with the hub of a motor vehicle and provided with means for locking, coaxial with the said rod, the fixing plate of the said rim so as to position said rod along the direction of the axis of said rim; thruster means able to act in any direction perpendicular to the rod itself, movable in a direction parallel to the said rod and provided with adjusting and support means and means for fixing their position along the said rod, said rod being mounted rotatably with respect to its axis, provided with actuating means and connected to means for detecting the balancing and geometrical deformation.
- In a preferred embodiment, said thruster means are arranged on support means which are mechanically and statically completely independent of said rod. Said thruster means may comprise two hydraulic jacks which are situated diametrically opposite each other relative to the axis of the said rod and mounted on a common support which is movable in a direction parallel to the said rod and can be fixed by suitable means in any position with respect to the said rod.
- Said hydraulic jacks are incorporated in a hydraulic circuit which allows them to be controlled so that a first jack is able to bear against the inner side wall of the rim and a second rim able to apply a given thrusting force along the same direction and in a sense diametrically opposite to the first jack, which counterbalances the effect thereof.
- The present invention also relates to a method for restoring the centering of tire rims by means of the apparatus described above, comprising the steps of:
-
- positioning the rim on the said rod and clamping the said rim;
- detecting the deformation of the rim and consequent eccentricity with respect to its axis by means of a device for detecting/determining the eccentricity;
- positioning and locking the thruster means;
- applying a given thrusting force on the rim by means of said thruster means;
- verifying the effect of the thrusting force by means of a device for detecting/determining the eccentricity;
- repeating steps d) and e) in succession until the rim has been re-trued.
- Further advantages of the apparatus according to the present invention and the method for use thereof will become clear from the following detailed description of an embodiment thereof, provided by way of a non-limiting example, with reference to the accompanying illustrations in which:
-
FIG. 1 is a side elevation view of an embodiment of the apparatus according to the present invention; -

FIG. 1 shows an embodiment of the apparatus according to the present invention; 1 denotes the support frame of the said apparatus, inside which the rod 2 is joined to the actuatingmeans 101 which are connected to detection means 201 in turn connected to thecentral processing unit 301 which supplies the data acquired and processed to themonitor 401. The rod 2 has, at the opposite end to that connected to the said actuating means 101, a threadedportion 102 having, joined thereto, therim fixing bush 112 provided with gripping means 122. The threaded portion terminates, as will appear more clearly from the figures described below, in adisk 202 which is keyed onto the rod 2. Themeans 3 for guiding thethrusters stirrup 104, are arranged concentric with the rod 2. The said guide means 3 are connected stably to thebracket 5 projecting out from the frame 1 in the manner better described below. -
FIG. 2 shows a front elevation view, with parts cross-sectioned, of a detail according toFIG. 1 ; identical parts have been given the same numbers. The rod which is shown cross-sectioned, is surrounded by the support bearing 302 which has, arranged around it, the twoguides 3 joined together by means of the bridge-piece 103. On the bottom side, the twoguides 3 are fixed by means of thefixing means 225, to the right-angled section 205 which, by means of the fixing means 215, is connected to theU-shaped section 105 which is in turn joined to thebracket 5 connected to the support frame of the apparatus. Each of the two guides, 3 is provided on the top side with achannel 203 inside which arail 134 is situated; inside one of the twochannels 203, theslide 124 is mounted on therail 134, said slide being connected to thestirrup 104 which joins the two thruster means which in the example illustrated are thehydraulic jacks other channel 203, theslide 144 is mounted on therail 134 and is passed through by ascrew pin 164 provided with aknob 174, the other free end of which is able to make contact with therail 134. Thehydraulic jacks ends 114 of thestirrup 104 in a diametrically opposite position relative to the rod 2 and are provided with themovable pistons -
FIG. 3 shows the same detail in a plan view from above, with the sole difference that in this case a rim is positioned on the apparatus; here also identical parts have been indicated by the same numbers. As can be noted, therim 10 is arranged with its hole 11 for centring with the hub of the vehicle wheel mounted on the threadedend 102 of the rod 2 and co-operating with the frustoconical end-piece 212 projecting from thedisk 202, while theplate 13 of the said rim rests on thedisk 202. Theside wall 12 of the rim is ready to enter into contact with thethrusters - Finally,
FIG. 4 shows schematically an embodiment of the hydraulic circuit of the apparatus according to the present invention; 6 denotes the pump of the circuit, which by means of thefilter 706 draws the hydraulic fluid, i.e. oil, from thetank 806, and is operated by themotor 106. The pump supplies two circuit branches both provided withmaximum pressure valves 206; one branch, which terminates in thehydraulic jack 4′ with itspiston 204′ and the resilient recall means 214′, has, arranged along it, a filling/emptyingvalve 406 which, when it is operated, allows positioning of thepiston 204′ bearing against theside wall 12 of therim 10. The other branch, which terminates in thejack 4 with itspiston 204 and the resilient recall means 214, incorporates therein amaximum pressure valve 306, a filling/emptyingvalve 506 and, at the jack connection point, a regulatingvalve 606 and apressure gauge 616. - The operating principle of the apparatus according to the invention and the method for re-centering rims by means of this apparatus will, become clear from the description provided below. Removing the
bush 112 from the threadedportion 102 of the rod 2, the rim may be positioned on thedisk 202 by means of itsplate 13; subsequent tightening of the bush causes centring of the hole 11 on the end-piece 212. At this point the first check is carried out on the rim, causing rotation of the rod and detecting, by means of thedetection device 201 and theprocessing unit 301, the deformation of its geometrical form, both in terms of magnitude and in terms of position. After completing the analysis, the thruster means 4, 4′ are conveniently positioned in order to perform repair, sliding thebracket 4 along theguides 3 and then suitably locking in position theslide 144 by means of theknob 174 which operates the threadedpin 164. - The next step envisages operation of the
thruster 4′, thepiston 204′ of which is brought into contact with theside wall 12 of the rim at the point diametrically opposite to that where the deformation has been encountered. The degree of thrusting force to be applied with thepiston 204 of thethruster 4 is suitably metered, making use of the controlling action which thevalve 606 is able to have on the fluid filled in the end portion of this branch of the circuit and detecting at the same time the pressure by means of thepressure gauge 616. Thepistons - Another important aspect of the design of the apparatus according to the present invention is associated with positioning of the thruster means 4, 4′ with respect to the rod 2 which must be able to rotate without being subject to influences of any kind, since, from its rotation with the rim mounted as shown in
FIG. 3 , it is possible to deduce the data relating to the position and the degree of damage to be repaired. In this respect, it is necessary to mention how inFIG. 2 the connection between the means for guiding the thruster means 4, 4′ and the frame of the apparatus is shown; basically, by means of thesections guides 3 are fixed to thebracket 5 without affecting in any way the static condition of the rod 2, and this type of arrangement allows any interference with rotation of the rod, and therefore any corruption of the data detected by thedevice 201 connected to the said rod, to be avoided.
