Abstract: The present invention concerns a tyre-changing machine provided with a basic structure that can rest on the ground, a retaining and rotation unit mounted on an upper part of the structure and adapted to retain and set the rim (C) of a wheel (R) in rotation around an axis of rotation of the wheel (Z-Z) and a holding column associated with the retaining and rotation unit and intended to support a tool for mounting/disassembling a tyre (P) onto/from the rim (C) of the wheel (R). Advantageously, the tool comprises a hooked end which can rotate passively around an axis of rotation (X-X) orthogonal to the axis of rotation of the wheel (Z-Z).

Abstract: A machine for fitting and removing the wheel tires of vehicles comprises a base frame with a turntable for gripping and rotating a rim of wheels for vehicles with at least a retention flange and a bead of a tire to be fitted on, or removed from, the rim; an operating head is operatively associated with the base frame, and is positionable near the retention flange. The operating head includes a guiding nut for the bead; a guiding wing for the bead; a grip tool for gripping the bead which is arranged between the guiding nut and the guiding wing, and includes a shaped active extremity with an oblique profile suitable for cooperating with the guiding nut for guiding the bead. Actuator assembly moves the grip tool between a first guiding configuration of the bead, in which the active extremity is arranged near the guiding nut and near the guiding wing, and a second grip configuration of the bead.

Abstract: A tire changing machine implement for fitting and removing tires of vehicle wheels, comprising at least one element that is engaged so that it can slide along a rectilinear guiding member and can be inserted between a tire and a vehicle wheel rim that is supported so that it can rotate about at least one rotation axis on a tire changing machine, the rectilinear guiding member being associable with the tire changing machine substantially at right angles to the axis of rotation and rotatable about an oscillation axis that is substantially parallel to the rotation axis.
