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.

The present invention concerns a wheel-holder including: a support base, a shaft slidingly movable with respect to the support base and having a plurality of stops, a support plate carried by the shaft and configured to receive the rim of a wheel, a block carried by the support base and configured to engage a stop for locking the shaft in an operating position, preventing the relative sliding between support base and shaft. The block includes an insert movable with respect to the shaft, a maneuvering element active on the insert and configurable between a thrust position and a release position. The block includes a pusher which, in the release position of the maneuvering element, thrusts on the insert to maintain it in engagement with the stop.

Described is a wheel service machine (1) comprising: a shaft (3) rotating about a relative longitudinal axis (A), and a contact element (4), connected to the shaft (3) for rotating integrally with it and designed to make contact with the rim (2a) supported by the shaft (3); a locking device (5), which can be removably coupled to the shaft (3) and designed to slide relative to the shaft (3) along the longitudinal axis (A) and lock the rim (2a) interposed between the contact element (4) and the locking device (5); a fastening element (6) movably connected to the shaft (3) for moving parallel to the longitudinal axis (A) and designed for coupling with the locking device (5), for pulling it in movement; actuator (7) positioned on the machine and connected to the fastening element (6), wherein the locking device (5) comprises an emitter (8) designed for generating a wireless control signal, received by a wireless signal receiver (9) connected to the actuator (7), activates them for moving the locking device (5).

The present invention regards a group for supporting and tightening a rim of or for a tired wheel, and such group includes a base, a wheel-holder table, an upright or column projecting upward from the base and supporting at the top the wheel-holder table, a shaft or pin mounted in or alongside the upright or column, a sleeve element or ring nut element constrainable or mountable on the shaft or pin and means for the relative movement of the shaft or pin and of the table.

A tire changing tool head, or a mount/demount head for a tire changing machine, includes a head body and a tongue member. The tongue member is pivotally attached to the head body at a pivoting joint. The tongue member includes a tongue shoulder and a tongue blade for engaging a tire bead during tire installation. The tongue member includes a non-metal material, such as a polymer, for preventing wheel rim damage in some embodiments. The head body includes a bead lifter tool protruding therefrom. In some embodiments, the head body and bead lifter tool include a metal material.

Provided is an automatic tire changer, relating to the technical field of tire repair and maintenance. The automatic tire changer includes a base configured to carry a carrier of a device; a column vertically disposed on the base; a tire mounting seat mechanism movably disposed on the base and configured to secure a rim when a tire is demounted or mounted; a first demounting and mounting apparatus movably disposed on the column and configured to demount or mount an upper portion of the tire; a second demounting and mounting apparatus movably disposed on the column and configured to demount or mount a lower portion of the tire; and a control system configured to run a program and control multiple components to run through an execution mechanism.

An apparatus for mounting and demounting a tyre relative to a corresponding wheel rim, wherein the apparatus includes: a wheel-holder unit, configured to receive and lock the wheel at an operating position and to set it in rotation about an axis of rotation; a plurality of tools, configured to interact with the tyre to mount and/or demount the tyre; a hydraulic circuit comprising a pump; a plurality of hydraulic actuators, connected to the hydraulic circuit; the hydraulic circuit is configured to drive the actuators of the plurality of actuators synchronously.
