The tyre-changing machine (10) for fitting and removing vehicle wheels comprises:
- a bed (12) for resting on the ground;
- a spindle (14) which extends from the bed (12) and on which is mountable a wheel (R) having a rim (C) and a tyre (PN) with two opposite flanks (F1, F2), the spindle (14) being configured to tighten the rim (C) on it and able to put in rotation the wheel (R) around an axis of rotation (A); and
- two bead breaking tools (32, 42) which are movable one towards the other in the proximity of the spindle (14) along a bead-breaking direction (D1) substantially parallel to the axis of rotation (A) of the spindle (14), the bead breaking tools (32, 42) having respective non-rolling contact surfaces (34, 44) able to contact and push in use the opposite flanks (F1, F2) with the wheel (R) mounted on the spindle (14). |
