摘要:
The present invention regards a group for supporting and tightening a rim of or for a tired wheel, and such group includes a base, a wheel-holder table, an upright or column projecting upward from the base and supporting at the top the wheel-holder table, a shaft or pin mounted in or alongside the upright or column, a sleeve element or ring nut element constrainable or mountable on the shaft or pin and means for the relative movement of the shaft or pin and of the table.

A bead guide includes a columnar portion having a cylindrical side surface, and a guide plate extending from a distal end of the columnar portion. Through rotation of the bead guide, an expansion bar rotation driving section selectively switches the bead guide between a first position at which the guide plate is retreated radially inwardly from an outer circumferential end of a wheel, and a second position at which at least a part of the guide plate protrudes radially outwardly from the outer circumferential end of the wheel. The bead guide is switched from the first position to the second position so that the guide plate is caused to enter below an upper bead.

The present invention is related to a method and an apparatus for assembling a tire (1) onto the rim (2) of a vehicle wheel or for disassembling a tire (1) from the rim (2) of a vehicle wheel. There is provided an electric motor (3) for rotationally driving the rim (2) and the tire (1) during the assembling or disassembling operation, tools (4, 5) for assembling or disassembling the tire (1) onto the rim (2) or from the rim (2), measuring means (6, 15, 16, 18) for measuring the tire temperature and/or forces acting on the tire during the assembling or disassembling operation, and recording means (7) for recording on at least one data carrier the measured values of the tire temperature and/or of the forces acting on the tire during the assembling or disassembling operation.

A bead guide (50) includes a columnar portion (51) having a cylindrical side surface, and a guide plate (52) extending from a distal end of the columnar portion (51). Through rotation of the bead guide (50), an expansion bar rotation driving section (41) selectively switches the bead guide (50) between a first position at which the guide plate (52) is retreated radially inwardly from an outer circumferential end of a wheel (H), and a second position at which at least a part of the guide plate (52) protrudes radially outwardly from the outer circumferential end of the wheel (H). The bead guide (50) is switched from the first position to the second position so that the guide plate (52) is caused to enter below an upper bead (TBU).

Apparatuses and methods for adapting a tire machine to accept small wheel assemblies. A first embodiment includes a cross shaped guide with clamp adapters that glide in unison to engage and disengage the small wheel assembly via a rim hooking structure that extends the reach of the OEM tire clamps. Each clamp adapter is set over the OEM tire clamps and is engaged or closed via an engagement clip and opened or disengaged via a disengagement clip disposed on each clamp adapter. Another embodiment includes individual clamp adapters that are slid over the OEM tire clamps to extend the reach of the OEM tire clamps. A stop hook is disposed on the clamp adapters to engage a clamp hook on the OEM tire clamp when the tire machine is activated which engages a raised adapter hook on each clamp adapter to the small wheel assembly rim edge.

The tyre-changing machine includes: a bed for resting on the ground; a spindle extending from the bed and for mounting thereon a wheel having a rim and a tyre with a first flank and a second flank, the spindle configured to tighten the rim thereon so as to fix an imaginary axis of rotation of the wheel, with the first flank arranged in a distal position with respect to the bed and the second flank in a proximal position with respect to the bed; and a demounting tool having a non-rolling contact surface for contacting and pushing the second flank in a direction away from the bed until extracting the first flank from the rim, the spindle and the demounting tool being reciprocally movable along a direction substantially parallel to the axis with a stroke extending between two ends, to push the tyre out of the rim during the stroke.

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.

A tyre mounting/dismounting machine (1), comprising a base (2), rotating means (3) for supporting and blocking a wheel (100) and a column (4) associated to the base (2), a first arm (7) and a second arm (8) being slidably mounted on the column (4), an upper first debeader tool (13) and a lower second debeader tool (9) being mounted respective at free ends of each arm (7, 8). Mounted at the free end of the first arm (7) is a head (10) which is rotatable with respect to an axis (Y), from which head a mounting tool (11), a dismounting tool (12) and the first debeader tool (13) project, the tools (11, 12, 13) being mounted in reciprocal positions such that the tools (11, 12, 13) do not interfere with one another and such that by rotating the head (10) with respect to the first arm (7) a same work position can be reached for each of the tools (11, 12, 13). Means for blocking (14, 15, 16, 17) are associated to the head (10) in three different positions, a same work position for each of the tools (11, 12, 13) corresponding to each of the three different positions.
