  • Patent number: 10259279
    Abstract: Machine for unseating a tire bead from a wheel, comprising a stand designed to rest on the ground, a bearing plate for the wheel, and a bead unseating tool which is connected to a tool bearing structure mobilely mounted to the stand. The machine comprises a pneumatic actuator for setting the tool bearing structure in motion in order to operate the tool, and a shock absorber connecting the tool bearing structure to the stand in order to damp the movement of the tool bearing structure, particularly at the moment at which the tire bead unseats from the rim of the wheel.
    Type: Grant

  • Patent number: 8590590
    Abstract: A machine for fitting and removing a tire (1) from a rim (2) of a wheel (3). The machine comprises a frame (10), a rotating table (11) for attaching the wheel to and for rotating the rim about its axis (Y), and a tool for fitting and/or removing the tire from the rim. The machine also comprises a lever (12) to which a pressure element (13) is attached in order to push the bead (6) of the tire toward a circumferential recess of the rim. The lever (12) is connected to the frame (10) and comprises a first articulation in order to bring a pressure element (13) closer to or further from the axis (Y), and a second articulation in order to bring the pressure element (13) closer to or further from a central plane (PC) perpendicular to the axis (Y) and passing through the center (D) of the rim (2).

  • Patent number: 8522851
    Abstract: Machine for fitting and removing a tire (1) from a rim (2) of a wheel (3). The machine comprises a frame (10), a rotating table (11) in order to attach the wheel thereto by its rim and to rotate the rim about its axis (Y), and a tool (12) for fitting and/or removing the tire from the rim. The tool (12) is connected to the frame (10) by means of a movable structure (20) capable of moving the tool (12) horizontally and vertically to its working position situated close to the proximal edge (4) of the rim (2) when the wheel (3) is mounted on the rotating table (11). The movable structure (20) comprises four arms (A, B, C, D) connected together in twos by means of four pivots (p, q, r, s) the axes (X1, X2, X3, X4) of which are parallel with one another. One of the arms (A) is secured to the frame (10) and the tool (12) is connected to one of the other arms (B, C, D).
