The main arm (400) is movable by translation parallel to the horizontal axis of translation (X) towards and away from a column (101) to keep the hinge point (F) vertically aligned with the vertical axis of rotation (Y) of the wheel-holder unit (200), responsive to a movement in translation of the wheel-holder unit (200).

A machine (M) for mounting and demounting a tyre (P) relative to a corresponding rim (C) of a vehicle wheel (R) comprises a column (100) including a slideway (101) to which there is slidably coupled a tool holder carriage (300) that includes a first arm (401) with a demounting tool and a mounting tool (402, 403) connected to it. The first arm (401) runs along a first, horizontal sliding axis (X1). The tool holder carriage (300) also comprises a second arm, provided with a bead seater tool (502) and slidable along a second, horizontal sliding axis (X2) that is spaced from the first sliding axis (X1), and a third arm (601) with a bead breaker disc (602) connected to it.

A tire changer apparatus for the assembly or disassembly of tires from a rim of a wheel of a vehicle, said tire changer apparatus comprising: a base; a drive unit movable along a predetermined direction and configured to rotate, around a rotation axis, a wheel of a vehicle; a frame emerging from the base. The rotation axis of the wheel and the predetermined direction define an ideal plane of movement of the drive unit. The apparatus also comprises a first and a second device, each of which comprises: an arm hinged to the frame and configured to rotate around a respective axis parallel to the rotation axis of the wheel, a tool configured to operate on a rim and/or a tire of a wheel; the first and second devices are configured to arrange the respective tools on opposite sides with respect to said ideal plane.

A tire changing machine of the present disclosure may comprises a chassis base, a rotatable wheel holder, a tower, and an arm. A linear actuator is attached to the tower via a pivoting arm assembly. The linear actuator includes an implement on a lower end of the linear actuator. The arm includes an elongate portion, a coupler, first and second ends, first and second halves, and first and second claws. The coupler is located at a central portion of the elongate portion and is operable to couple the arm to the implement of the linear actuator. The first and second claw are operable to engage a tread portion of a tire.

The present invention relates to an apparatus for attaching or detaching a commercial vehicle tire hub drum. According to the present invention, the apparatus for attaching or detaching a commercial vehicle tire hub drum may comprise: a main body frame 100 having traveling wheels 110 mounted on a lower part thereof; a holding means 200 formed so as to face forward from the main body frame 100 for holding upright a circular load mounted on a commercial vehicle; an attachment/detachment means 300 for executing an attachment/detachment operation of the load from above the holding means 200; and a position adjustment device 400 coupled to the main body frame 100 to adjust the position of the holding means 200 and the attachment/detachment means 300. Accordingly, the present invention provides an apparatus for attaching or detaching a commercial vehicle tire hub drum, which, by using a hydraulic device providing a hydraulic driving force, can conveniently attach or detach a load of various sizes to a vehicle from a fixed position while simultaneously adjusting the vertical position of a load-holding means.

A tire changer apparatus includes: a base, a wheel-holder configured to rotate a wheel around a rotation axis, a first and second column emerging from the base, a first device having an extensible arm carrying a tool, a second device having a respective extensible arm carrying a tool opposite the tool of the first device with respect to an ideal middle plane of the apparatus. The tire changer apparatus further includes: a first and a second bar respectively connecting the arms of the first and second devices, a transmission which connects the first and the second bar to synchronize the movement of the arms of the first and second devices.

A tire changer apparatus for the assembly or disassembly of tires from a rim of a wheel of a vehicle, said tire changer apparatus comprising: a base; a drive unit movable along a predetermined direction and configured to rotate, around a rotation axis, a wheel of a vehicle; a frame emerging from the base. The rotation axis of the wheel and the predetermined direction define an ideal plane of movement of the drive unit. The apparatus also comprises a first and a second device, each of which comprises: an arm hinged to the frame and configured to rotate around a respective axis parallel to the rotation axis of the wheel, a tool configured to operate on a rim and/or a tire of a wheel; the first and second devices are configured to arrange the respective tools on opposite sides with respect to said ideal plane.

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 tyre changing apparatus (1) comprises: a frame (10); a supporting element (11) for supporting a wheel (2) rotatably about an axis of rotation (A); an arm (12) movably connected to the frame (10) to be moved by an actuator (5B, 5B) along a direction of movement (B) parallel to the axis of rotation (A); a bead breaker tool (13) connected to the arm (12) to move between an activated position, where it is in contact with the tyre (3), and a deactivated position, where it is spaced from the tyre (3); a control unit (14). The bead breaker tool (13) includes a mounting element (13A) and a bead breaker disc (13B) which rotates freely relative to the mounting element (13A) and comprises a sensor (131), configured to generate a contact signal (132) representing a rotation of the bead breaker disc (138) relative to the mounting element (13A); the control unit (14) is connected to the sensor (131) to receive the contact signal (132).
