Embodiment Construction

[0034] With particular reference to these figures, indicated generally at 1 is a bead breaking unit which can be mounted on a tire changing machine A of known type and which can be used to replace the tires of tire B prior to the mounting / demounting operations of tire B itself. The rim is detached from the corresponding rim C of wheel D first.

[0035] The bead breaking unit 1 comprises an arm 2 rotatably connected to a support structure 3 , a bead breaking tool 4 supported by the arm 2 , and a movement device 5 connected to the arm 2 .

[0036] The bead breaking tool 4 preferably consists of a so-called blade.

[0037] As shown in the illustration, the support structure 3 may consist of supports cantilevered from the fuselage E of the tire changing machine A. As shown in FIG.

[0038] However, other alternatives cannot be ruled out, wherein for example the support structure 3 consists directly of the fuselage E of the tire changing machine A, or in any case directly consists...

Abstract

The bead breaking unit (1) for tyre changing machines (A) comprises one arm (2) associated rotatable with a supporting structure (3), a bead breaking tool (4) associated with the arm (2) and movement means (5) associated with the arm (2) and suitable for moving the arm (2) from a disengagement position, wherein the bead breaking tool (4) is substantially moved away from the tyre (B) of a wheel (D) to undergo bead breaking, to an operating position, wherein the bead breaking tool (4) is engaged on the tyre (B). The arm (2) comprises adjustment means (9) for adjusting the position of the bead breaking tool (4) along a near / away direction to / from the wheel (D), suitable for adjusting the position of the bead breaking tool (4) when the arm (2) is in the disengagement position, depending on the sizes and / or type of the wheel (D).

Description

technical field [0001] The invention relates to a bead breaking unit for a tire changing machine. Background technique [0002] Tire changing machines are commonly used for mounting / dismounting vehicle tires to / from respective rims. [0003] As is known, before the tire can be completely detached from its casing on the respective rim, the beads of the tire need to be detached from the bead-retaining edge of the rim itself. [0004] This operation is carried out by means of a suitable bead breaking unit which is usually provided on the tire changing machine. [0005] Bead breaking units of known type generally comprise an arm having a first end and a second end, the first end being articulated to the body of the tire changing machine according to a substantially vertical axis, This second end has a bead breaking tool, also called a blade. [0006] Fixed to the body is a support element that can be used to properly mount the rim during the bead breaking operation. [0007]...
