Definitions

  • This invention relates to apparatus and a method for fitting a tyre to a wheel rim.
  • This invention is particularly suited for fitting a solid tyre to a split type wheel rim or to a lock ring type wheel rim and it will be convenient to hereinafter describe the invention in relation to those exemplary applications.
  • Solid tyres can be fitted to either a split type wheel rim or to a lock ring type wheel rim.
  • a split type wheel rim has two halves which fit on either side of the tyre. The two split rim halves are pressed through the tyre towards each other and then fixed together. Fixing is generally by means of a plurality of nuts and bolts.
  • a lock ring type wheel rim is designed to pass through the tyre and the tyre is locked into place by locking rings (which may be 2, 3 or 4 pieces) which fit under a lip in the rim and bear against the side wall of the tyre.
  • Presses of the prior art are generally large and can include a structure of substantial size in comparison to the size of the tyre to be fitted to the wheel rim.
  • the present invention seeks to overcome these disadvantages of the prior art by providing apparatus which is compact and may be used for fitting a range of sizes of tyres to a range of sizes of wheel rims on site.
  • the present invention also seeks to provide an apparatus which protects the wheel rim during the process of fitting the tyre to the wheel rim.
  • an apparatus for use in fitting a tyre to a wheel rim including: a base member; an actuating means associated with the base member; a pull jig connectable in use to the actuating means; and a protecting means for protecting the wheel rim and positionable in use adjacent the base member.
  • the wheel rim and tyre are positioned between the base member and the pull jig and the actuating means operates to pull the pull jig towards the base member fitting the tyre to the wheel rim and the protecting means protects the wheel rim during the operation of the actuating means.
  • this apparatus provides the wheel rim with protection while the tyre is being fitted to the wheel rim.
  • the actuating means includes a ram positioned on a side of the base member, a pull rod extending from the ram out an opposite side of the base member for engagement by the pull jig wherein in use the wheel rim is positioned relative to the pull rod so the pull rod extends through an opening in a central portion of the wheel rim. Having the actuating means extending through a central portion of the wheel rim avoids limiting the apparatus to use with a wheel of a specific configuration.
  • the pull jig includes a female screw thread and the pull rod includes a threaded portion having a male screw thread with the pull jig being adjustable along the length of the threaded portion by screw mounting the pull jig onto the threaded portion. This permits the pull jig to be adjusted along the threaded rod to bring the pull jig proximate the tyre and rim before the ram operates thus making more efficient use of the movement of the ram.
  • the pull jig includes three arms extending from a central portion of the pull jig with the female thread located at the central portion. This arrangements makes the pull jig suitable for use with tyres and wheel rims of varying diameters.
  • the protecting means spaces the wheel rim from the base member to prevent the wheel rim from being crushed into the base member during the operation of the actuating means. Spacing the wheel rim from the base member stops the wheel rim from being damaged by inappropriate contact with the base member.
  • the protecting means include a metal portion and an elastomer portion wherein in use the metal portion is positioned adjacent the base and the elastomer portion is positioned adjacent the wheel rim.
  • the metal portion is steel and the elastomer portion is a synthetic rubber.
  • the wheel rim is a split wheel rim formed from a first half split rim and a second half split rim wherein in use fitting the tyre to the split wheel rim includes positioning the first half split rim adjacent the protecting means with the tyre positioned between the first half split rim and the second half split rim, wherein the pull jig engages the second half split rim with the actuating means pulling the pull jig and the second half split rim towards the first half split rim so that the first half split rim and second half split rim can be fixed together.
  • a protecting pad be positionable in use between the protecting means and the first half split rim to protect the protecting means when in use.
  • the first half split rim and second half split rim are fixed together using a plurality of nuts and bolts wherein in use the heads of the bolts engage the surface of the protecting pad to facilitate tightening of the nuts on the bolts.
  • the heads of the bolts dig in to the protecting pad so that the bolts cannot spin when the nuts are being tightened on the bolts.
  • the protecting pad be independent from the protecting means so that the protecting pad may be replaced when worn.
  • a split rim jig be positioned in use between the pull jig and the second half split rim to facilitate pulling of the second half split rim towards the first half split rim.
  • the wheel rim is a lock ring wheel rim wherein in use fitting the tyre to the lock ring wheel rim includes positioning the lock ring wheel rim adjacent the protecting means, positioning the tyre between the lock ring wheel rim and the pull jig with the actuating means pulling the pull jig to bear against the tyre compressing the tyre to permit a locking ring to be fitted to the lock ring wheel rim. It is still further preferred that a lock ring jig be positionable in use between the pull jig and the tyre to facilitate compression of the tyre.
  • an extension means associated with the pull jig be positionable in use between the pull jig and the lock ring jig to further facilitate fitting of the lock ring to the lock ring wheel rim. It is still further preferred that the lock ring is to be formed from 2, 3 or 4 parts.
  • the tyre be a solid tyre.
