Patent ID: 7896054

Claim:
A machine for fitting and removing wheel tires for vehicles, comprising a supporting structure of a clamping and rotating device for clamping and rotating a wheel rim for vehicles, at least an operating unit movable with respect to said supporting structure and having at least an operating head for fitting/removing a tire onto/from said rim, said operating head having at least one removal tool associated with a first actuator and turnable between a first clamping position of at least a section of the bead of said tire in which said tool is substantially tilted towards a rotation axis of said rim, and a second entrainment position of said bead section in which said tool extends along a direction substantially parallel to the rotation axis of said rim, wherein said operating unit comprises a second actuator and transformation arrangement for transforming the movement generated by said second actuator into the sideways movement of said operating head along a direction substantially curved between a first configuration in which said operating head is substantially near to a section of the annular flange of said rim suitable for housing said bead section, and a second configuration in which said operating head is substantially away from said section of the annular flange of the rim, wherein said operating unit comprises at least a transmission element for transmitting the movement generated by said second actuator to said tool, during the sideways movement of said operating head, for the rotation of said tool between said second position and a third position of entrainment of said section of the bead, in which said tool is substantially tilted in the opposite direction with respect to the rotation axis of said rim, and wherein said transmission element is associated with a first system of levers and with a second system of levers, wherein said first system of levers is associated with said first actuator and with said tool and said second system of levers is associated with said second actuator and with said operating head.
