A tyre changing machine (1), configured to remove a tyre from a respective rim of a vehicle wheel (2), comprises an operating arm (4) which includes: a supporting structure (401); a head (5) movable along a longitudinal axis (402) relative to the supporting structure (401); a removal tool (403) pivoted to the head (5) to rotate relative thereto about an axis of oscillation (405) transverse to the longitudinal axis (402); a driving member (6) movable along an operating axis (402) parallel to the longitudinal axis (402) relative to the supporting structure (401) and to the head (5), and articulated to the removal tool (403) at an operating point (P) which is spaced from the axis of oscillation (405); an actuator (407) comprising a stationary member (407a), connected to the supporting structure (401), and a movable member (407b), adapted to drive the removal tool (403) in rotation and in translation; a coupling member (7) coupled to the supporting structure (401), to the head (5) and to the driving member (6). The movable member (407b) of the actuator (407) is connected to the driving member (6) to directly drive it along the operating axis (402).

A tyre changing apparatus (1) for demounting and mounting a tyre relative to a respective rim of a vehicle wheel (2) includes: a frame (10); a chuck (11) rotating about an axis of rotation (A); a working tool (12), connected to the frame (10) and movable towards and away from the chuck; an electric motor (13), imparting to the chuck (11) a rotation speed and a working torque; a controller (14), including a power unit (141) supplying voltage and current as a function of a drive signal (101); a processing unit (142) generating the drive signal (101) and programmed to derive a control parameter (102) representing the working torque delivered to the electric motor (13) and to apply a torque-limiting function responsive to the control parameter (102). The processing unit (142) derives an activation parameter and, as a function of the activation parameter, enables and disables the torque-limiting function.

A mounting/demounting tool for mounting/demounting a tire with respect to the rim of a vehicle wheel, comprising a tool body defining a first end of the tool, an extension from the tool body defining a second end of the tool, and a hook arranged at the extension in the vicinity of the second end. The hook has an inner surface section for gripping and guiding a tire bead during tire demounting, and a first outer surface section for guiding a tire bead during tire mounting. A protrusion extends from between the first outer surface section and a second outer surface section of the hook to the second end.

A method of mounting a tire to a wheel includes rotating a tire about an axis of the tire at a first rotation speed and moving a first tire engaging member into contact with the sidewall of the tire, thereby moving a proximate section of a bead of the tire into a well of the wheel. The method further includes moving a second tire engaging member into contact with the sidewall of the tire and rotating the second tire engaging member about the axis of the tire at a second rotation speed different from the first rotation speed. The method also includes moving the second tire engaging member out of contact with the sidewall of the tire and moving the first tire engaging member out of contact with the sidewall of the tire.

The present invention relates to a device for dismounting a tired wheel having a wheel rim and a tire mounted on the wheel rim, including: a support member, a bill or lever-shaped dismounting tool having one end thereof articulated to the support member, and the other work end thereof substantially hook-shaped, and holding means for holding the tool in an engagement and extraction position, the holding means including an elastically loaded pin.

A device for fitting and removing a tire on a rim, comprises: a working assembly movable along at least one first direction to vary its level with respect to the rim and provided with at least one tool adapted to interact with the tire; where the working assembly comprises at least one supporting element movable along the first direction, at least one fitting tool and one removal tool of the tire which are separate from each other and locked together with the supporting element along the first direction, wherein the fitting tool and the removal tool are movable with respect to each other along at least one direction of work which is transverse with respect to the first direction.

A machine for fitting and removing a tyre from a corresponding rim of a wheel of a vehicle, comprising: a wheel-holder unit rotating about a first axis (A) and slidably coupled to a groove provided in a base; a column; an upper operating head, provided with at least one upper fitting tool, at least one further tool, angularly spaced from the upper fitting tool, by a predetermined angle, and a wall pressing tool that can be placed in a working position which is operatively in contact with the wheel simultaneously with the upper fitting tool.

Described is a machine (1) for fitting and removing a tire (2) from a corresponding rim (3) of a wheel (4) of a vehicle, comprising: a wheel-holder unit (6) rotating about a first axis (A); a column (8); an upper operating head (16), provided with at least one upper fitting tool (18), at least one further tool, angularly spaced from the upper fitting tool (18), by a predetermined angle, and a wall pressing tool (21) that can be placed in a working position which is operatively in contact with the wheel simultaneously with the upper fitting tool (18).

A tyre changing machine (1), configured to remove a tyre from a respective rim of a vehicle wheel (2), comprises an operating arm (4) which includes: a supporting structure (401); a head (5) movable along a longitudinal axis (402) relative to the supporting structure (401); a removal tool (403) pivoted to the head (5) to rotate relative thereto about an axis of oscillation (405) transverse to the longitudinal axis (402); a driving member (6) movable along an operating axis (402) parallel to the longitudinal axis (402) relative to the supporting structure (401) and to the head (5), and articulated to the removal tool (403) at an operating point (P) which is spaced from the axis of oscillation (405); an actuator (407) comprising a stationary member (407a), connected to the supporting structure (401), and a movable member (407b), adapted to drive the removal tool (403) in rotation and in translation; a coupling member (7) coupled to the supporting structure (401), to the head (5) and to the driving member (6). The movable member (407b) of the actuator (407) is connected to the driving member (6) to directly drive it along the operating axis (402).

A machine (1) configured to remove and mount a tyre from and on a respective rim of a vehicle wheel (2), comprises: an operating arm (4) directed along a longitudinal orientation; a head (5) supported by the operating arm (4); a first tool and a second tool. The first tool is connected to the head (5) and projects in a first direction; the second tool is connected to the head (5) and, in a first operating configuration of the head (5), is disposed in a first position where it projects in a second direction, opposite to the first direction. The second tool is pivoted to the head (5) to rotate about an axis of tilt (406) transverse to the longitudinal orientation (402) to move from the first position to a second position, corresponding to a second operating configuration of the head (5) and tilted upside down relative to the first position, to project in the first direction.
