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.

In a device (1) for clamping a rim (2) of a vehicle wheel, at least four clamping elements (3) are provided which can be moved with respect to the rim (2) and comprise clamping arms (5) and support elements (7) having support surfaces (6). A rim flange of the rim (2) can be placed on the support surfaces. The clamping arms (5) are rotatably mounted, about their longitudinal axis, in the clamping elements (3), and have clamping fingers (8) at the end that protrude beyond the support surfaces (6), which fingers have clamping surfaces which can be brought into clamping contact with the placeable rim flange.
摘要:
Methods and machines for changing tires on a wheel rim are disclosed. The machine includes a drive shaft having a drive axis that can positioned at different angles for convenience of the machine operator to mount a variety of differently-sized wheel rims to the drive shaft without undue lifting and handling of the wheel rims.
摘要:
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).

摘要:
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.
