Abstract: The tyre-changing machine (10) for fitting and removing vehicle wheels includes: 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 (Di) 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 with the wheel (R) mounted on the spindle.

Abstract: The tyre-changing machine includes: a bed for resting on the ground; a spindle extending from the bed and for mounting thereon a wheel having a rim and a tyre with a first flank and a second flank, the spindle configured to tighten the rim thereon so as to fix an imaginary axis of rotation of the wheel, with the first flank arranged in a distal position with respect to the bed and the second flank in a proximal position with respect to the bed; and a demounting tool having a non-rolling contact surface for contacting and pushing the second flank in a direction away from the bed until extracting the first flank from the rim, the spindle and the demounting tool being reciprocally movable along a direction substantially parallel to the axis with a stroke extending between two ends, to push the tyre out of the rim during the stroke.

Abstract: The bead breaking unit includes: a bead breaking arm having a substantially horizontal longitudinal direction, a first extremity hinged to the base frame of a tyre changing machine around a substantially vertical rotation axis and an opposite second extremity having a bead breaking tool; an operating actuator for moving the bead breaking arm interposed between the base frame and the bead breaking arm; and a control lever, associated with the bead breaking arm in proximity of the second extremity for controlling the operating actuator, wherein the control lever is hinged around an oscillation axis substantially horizontal and parallel to the longitudinal direction and is associated with return elements for maintaining the control lever in a substantially vertical balance position, the actuator being controlled in a first direction for bead breaking the tyre when the control lever is rotated towards the wheel starting from the balance position.
