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.

Tyre changing machine

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.
