Abstract:
The present disclosure relates to a tool for supporting and locking a rim or tired wheel in position on a tire mounting-demounting machine for automobile wheels equipped with support table (2) with an axial hole or opening (2a), the tool comprising grip-release device (3) for a tired wheel (TW) or a rim (W) to be handled, and locking means for locking the grip-release device (3) to the support table (2) and/or for locking the rim (W) or tired wheel (TW) against components of the grip-release device (3).
Abstract:
The present invention relates to a device for dismounting a tired wheel having a wheel rim (W) and a tire (T) mounted on the wheel rim (W), comprising: a support member (2), a bill or lever-shaped dismounting tool (4) having one end (4a) thereof articulated to the support member (2), and the other work end (4b) thereof substantially hook-shaped, and holding means for holding the tool (4) in an engagement and extraction position, the holding means comprising an elastically loaded pin (7).
Abstract:
A device for automatic demounting of a tire from a rim having: a support arm (4); a demounting tool (10) articulated to the support arm (4); an attachment member (12) having one end articulated to the demounting tool (10) by a first articulation pin (13) and the other end thereof pivoted to the support arm (4) around a second articulation pin (14) extending substantially parallel to the first articulation pin (13); at least one extension appendage of the support arm (4) or a section (17) of the support arm (4), which extends beyond the second articulation pin (14); and at least one tie rod member (18) that is articulated on one side to the tool, and on the other side to the extension appendage or section (17) of the support arm (4).
Abstract:
The present invention relates to a work head with bead breaker roller for a tire mounting-demounting machine, suitable for bead breaking of a tire (P) from the edge (B1) of a rim (C) of a tired wheel, the work head comprising: a head-holder support (10) fixable to a bead breaker arm of a tire mounting-demounting machine; at least one bracket member (6) pivoted at one end thereof to the head-holder support (10) around a pivoting axis (x-x); a bead breaker tool (2) supported at the other end of the at least one bracket member (6) and designed to engage a bead of a tire to be bead broken (P); a lever element (7), which is pivoted to the head-holder support (10) and bears a feeler pin arm portion (9) designed to control, in use, the lever element (7), whereby it is angularly moved between a work position, in which it thrusts against the bead breaker tool, and at least one rest position, it which it is angularly arranged at a distance from the bead breaker tool (2); and return means (10) designed to yieldably keep the lever element (7) in the work position.
