Abstract: A tyre changing machine includes a wheel support assembly for locking and setting in rotation a rim of a wheel from which to demount or on which to mount a tyre, and a bead breaking tool disposed at an end of a bead breaking arm and able to carry out the bead breaking operation. The bead breaking arm is movable between a disengaged position and a working position. A motor device has an output drive shaft for moving the bead breaking arm between the disengaged and working positions. Means for transmitting the drive from the motor device to the bead breaking arm include threaded means having an external screw-thread and hollow counter-threaded means operatively coupled with the threaded means. Connecting means operatively associate the means for transmitting the drive to the bead breaking arm.

Abstract: A tyre changing machine includes a frame; a wheel support assembly mounted on the frame for locking and setting in rotation a rim of a wheel; at least a bead breaking arm; and a bead breaking tool adapted to carry out the bead breaking operation of the tyre of the wheel. The bead breaking arm is movable between a disengaged position, in which the bead breaking tool is substantially distanced with respect to the tyre, and a working position, in which the bead breaking tool can engage on the tyre. A motor device has an output drive shaft for moving the bead breaking arm. The tyre changing machine further includes means for transmitting drive from the motor device to the bead breaking arm or to the wheel support assembly and adapted to activate the bead breaking arm or the wheel support assembly.

Abstract: A lifting apparatus for a vehicle wheel comprising a wheel support which is selectively movable in order to lift or lower a vehicle wheel which is positioned thereon. An actuator group is connected to the wheel support in order to actuate the lifting and lowering thereof. A control unit is operationally connected to the actuator group in order to control the actuation. A lifting sensor member is provided to detect the height of the wheel support. At least one actuation instruction brings about the actuation of the actuator group in order to lift the wheel support from a lowered rest position to a predetermined lifting position, which is detected by the lifting sensor member.

Abstract: A method and associated apparatus for uniquely identifying tyres for wheels of vehicles as part of wheel maintenance processes. The method envisages that a vehicle wheel is mounted on a support of a wheel maintenance apparatus, said wheel comprising a rim and a tyre. Moreover, a digital code is created to uniquely identify the tyre. Finally, via a marking system, preferably of the optical type, at least one marking is created on the surface of one side wall of the tyre of said wheel, corresponding to the previously created digital code.

Abstract: A lifting device (10, 40) for at least one wheel (8) of a vehicle or for a tire (6), said device (10, 40) comprising at least one platform (12, 41, 42) on which the wheel (8) or tire (6) moves, said platform (12) being liftable relative to a fixed surface (P). The movable platform (12) is associated with a laser scanner (20) for detecting the state of wear of the tire (6).
