Apparatus and process for the assembly and disassembly of tires

A tire changer apparatus for the assembly or disassembly of tires from a rim of a wheel of a vehicle, said tire changer apparatus comprising:

• a base;
• a drive unit coupled to the base and configured to receive and rotate around a rotation axis at least one wheel of a vehicle;
• a frame emerging from the base, wherein the drive unit is movable with respect to the base, along a predetermined direction transverse to the rotation axis, close to and away from the frame, wherein the rotation axis of the wheel and the predetermined direction define an ideal plane of movement of the drive unit;
• and
• a first device and a second device each of which comprises:
• at least one arm hinged to the frame and configured to rotate around a respective axis substantially parallel to the rotation axis of the wheel;
• and
• at least one tool terminally carried by the at least one arm and configured to operate on a rim or a tire of a wheel carried by the drive unit,
• wherein the first and second devices are configured to arrange the respective tools on opposite sides with respect to said ideal plane,
• wherein a preponderant part of the arm of the first device is extended along a main extension direction that is substantially rectilinear, wherein the first device, at least during a work condition in which the tool of said first device is adapted to contact the tire, is configured to allow the rotation of the respective arm so that the main extension direction of the latter substantially intersects the rotation axis of the wheel, and
• wherein a preponderant part of the arm of the second device is extended along a main extension direction that is substantially rectilinear, wherein the second device, at least during a work condition in which the tool of said second device is adapted to contact the tire, is configured to allow the rotation of the respective arm so that the main extension direction of the latter substantially intersects the rotation axis of the wheel.
