Abstract
An apparatus for tire-changing machines includes a base having a face turned upward, a supporting and locking platform for wheels, mounted rotating on such face around a rotation axis and defining a supporting and locking table, support means of tools extending upward from the base, the support means being movable along the base in a direction of movement perpendicular to the rotation axis, so as to move closer or away from the rotation axis.
Claims16
An apparatus for a tire-changing machine comprising:
- a base having a face turned upward;
- a supporting and locking platform for a wheel, mounted rotatably on the face around a rotation axis and defining a supporting table;
- and
- support means of tools extending upward from the base, the support means being movable along the base in a direction of movement perpendicular to the rotation axis so as to move closer or away from the rotation axis,
- wherein the tools comprise,
- one or more bead breaking elements to bead break or remove a bead of a tire from a rim of the wheel,
- an introduction member fitted on first carriage means to hold the bead inside the rim and cooperating with the one or more breaking elements, and
- an extraction tool.

A method of fitting or removing a tire of a wheel on or from a rim, the method comprising:
- tightening the wheel on a supporting and locking platform of a tire-changing machine, the platform rotating around a rotation axis and defining a supporting and locking table;
- and
- positioning fitting or removal tools in an operating position near the wheel,
- wherein the fitting or removal tools are fittable on a common support element shaped as a support column extending from the tire-changing machine, and
- wherein the positioning comprises moving the common support element with respect to the tire-changing machine between a fitting or removal position near the platform and an idle position, away from the platform, and vice versa, the fitting or removal tools comprising bead-breaking tools, introduction tools, or extraction tools,
- wherein the moving comprises moving in a direction of movement to and from the platform, the direction of movement being straight and perpendicular to the rotation axis, and
- wherein the positioning comprises further moving the introduction tools with respect to the common support element in a direction parallel to the direction of movement.
