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.

A wheel clamping system, for reversibly clamping a motor vehicle wheel with a rim onto a wheel servicing machine, includes a handle for acting on a rim of the wheel mounted on a rotatable spindle. The handle has a coupling surface for engaging with clamping jaws of a pull rod when the clamping jaws are open. The handle includes a force detecting device for determining an amount of force exerted by the handle on the rim of the wheel, and a signal emitter operatively connected to the force detecting device. The signal emitter is configured to wirelessly transmit a control signal to a signal receiver of the wheel balancer operatively connected to an actuator causing axial movement of the pull rod when the determined amount of force reaches a predefined threshold, such that the actuator is actuated and the wheel clamping system performs a reversible clamping operation.

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.
