Abstract
A machine for assembling and disassembling a tyre fitted with a rigid inner run-flat ring, wherein the machine is a tyre removing machine having a turntable; a tool column located alongside the turntable and having a guide located alongside and parallel to the turntable; a slide mounted to run along the guide; and an actuating device for moving the slide along the guide; the tyre removing machine having tooling defined by a first tool fitted to the turntable to support the tyre and the rigid ring, and by a second tool fitted to the slide and movable with the slide along the tool column to engage the rigid ring and move the rigid ring with respect to the tyre.
Claims19
A machine for assembling and disassembling a tyre fitted with a rigid inner run-flat ring located inside a toroidal chamber of the tyre;
- the machine being a tyre removing machine comprising:
- a turntable having an axis;
- a tool column located alongside the turntable and having a guide parallel to said axis;
- a slide mounted to run along the guide;
- actuating means for moving the slide along the guide;
- and
- tooling for interacting with the tyre and the rigid inner run-flat ring, the tooling including:
- a first tool which is fitted to the turntable to support the tyre and the rigid ring, and supports the tyre over the turntable and at a given distance from the turntable so that the rigid ring can be arranged transversally through a central channel of the tyre;
- and
- second tool fitted to the slide and movable with the slide along the tool column to engage the rigid ring and move the rigid ring with respect to the tyre and through the central channel of the tyre, wherein
- the first tool includes first and second supporting means for supporting the tyre, laid flat, in respective distinct positions along said axis, the second supporting means being located above the first supporting means along said axis,
- the second supporting means is substantially annular, and includes a first curved plate and a second curved plate coplanar with each other, crosswise to said axis, and diametrically opposite with respect to said axis, and
- said first and said second curved plates are adjustable in height with respect to the first supporting means.
Tooling attachable to a tyre removing machine to assemble and disassemble, on the tyre removing machine, a tyre fitted with a rigid inner run-flat ring located inside a toroidal chamber of the tyre;
- the tyre changing machine being of the type comprising:
- a turntable having an axis;
- a tool column located alongside the turntable and having a guide parallel to said axis;
- a slide mounted to run along the guide;
- and
- actuating means for moving the slide along the guide;
- and
- the tooling for interacting with the tyre and the rigid inner run-flat ring, the tooling including:
- a first tool which fits onto the turntable to support the tyre and the rigid ring and supports the tyre over the turntable and at a given distance from the turntable so that the rigid ring can be arranged transversally through a central channel of the tyre;
- and
- a second tool which fits onto the slide, and is movable with the slide along the tool column to engage the rigid ring and move the rigid ring with respect to the tyre and through the central channel of the tyre, wherein
- the first tool includes first and second supporting means for supporting the tyre, laid flat, in respective distinct positions, the second supporting means being located above the first supporting means along said axis,
- the second supporting means is substantially annular, and includes a first curved plate and a second curved plate coplanar with each other, and which are positioned, in use, crosswise to said axis and diametrically opposite with respect to said axis, and
- said first and said second plates are adjustable in height with respect to the first supporting means.
A machine for assembling and disassembling a tyre fitted with a rigid inner run-flat ring located inside a toroidal chamber of the tyre, the machine being a tyre removing machine comprising:
- a turntable having an axis;
- a tool column located alongside the turntable and having a guide parallel to said axis;
- a slide mounted to run along the guide;
- actuating means for moving the slide along the guide;
- and
- tooling for interacting with the tyre and the rigid inner run-flat ring, the tooling including:
- a first tool, which is fitted to the turntable to support the tyre and the rigid ring and supports for the tyre over the turntable and at a given distance from the turntable so that the rigid ring can be arranged transversally through a central channel of the tyre;
- and
- a second tool fitted to the slide and movable with the slide along the tool column to engage the rigid ring and move the rigid ring with respect to the tyre and through the central channel of the tyre, wherein
- the second tool is a pressure tool including a first and a second pad, which are movable with the slide along said axis, and selectively engage the rigid ring to cause the rigid ring to translate along said axis with respect to the tyre, and to rotate with respect to the tyre about a further axis crosswire to said axis, and
- the first and second pad are located on opposite sides of said axis, and are offset in height, with the first pad located above the second pad.
A machine for assembling and disassembling a tyre fitted with a rigid inner run-flat ring located inside a toroidal chamber of the tyre, the machine being a tyre removing machine comprising:
- a turntable having an axis;
- a tool column located alongside the turntable and having a guide parallel to said axis;
- a slide mounted to run along the guide;
- actuating means for moving the slide along the guide;
- and
- tooling for interacting with the tyre and the rigid inner run-flat ring, the tooling including:
- a first tool, which is fitted to the turntable to support the tyre and the rigid ring and supports the tyre over the turntable and at a given distance from the turntable so that the rigid ring can be arranged transversally through a central channel of the tyre;
- and
- a second tool fitted to the slide and movable with the slide along the tool column to engage the rigid ring and move the rigid ring with respect to the tyre and through the central channel of the tyre, wherein
- the second tool is a pressure tool including a first and a second pad, which are movable with the slide along said axis, and selectively engage the rigid ring to cause the rigid ring to translate along said axis with respect to the tyre, and to rotate with respect to the tyre about a further axis crosswire to said axis, and
- the second tool includes a rod parallel to said axis and connected in an axially adjustable position to the slide, the rod having an inclined lateral appendix extending through said axis and towards the turntable, the first pad being carried by the rod, and the second pad being carried by the appendix.
