The present invention regards a group for bead releasing a tyred wheel and/or for thrusting a portion of a tyre (T) of a tyred wheel (TW), and such group comprises a base, a supporting column rising from the base, a tool-supporting arm extending from the supporting column and a bead releasing and/or thrust tool supported by the tool-supporting arm.

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.

A machine (1) for fitting and removing a tire (2) from a corresponding rim (3) of a wheel (4) of a vehicle, comprises: a rotating wheel-holder unit (6); a column (8); an upper arm (15) and a lower arm (23) slidably coupled to the column (8); an upper operating head (16); a lower operating head (24), rotating about a third axis of rotation (C) and equipped with a lower fitting tool (33), elongate in a direction for being operatively inserted between a lower bead of the tire (2) and an upper edge of the rim (3) and angularly spaced from the lower bead breaker tool (32) by a predetermined angle, so that the tools are selectively and alternatively positionable in an operating configuration.
