Problems solved by technology

[0022] In fact, the fastening of the rim of the wheel to the hub, or at any rate close to the hub, for example by conventional pins with conical bodies, cannot be performed on all types of tires
[0023] For example, in the case of motorcycle tires, it is in most cases impossible to use hub clamps due to the small size of such tires or the lack of a central through hole and / or other fastening holes in the rim

Embodiment Construction

[0034] With reference to these drawings in detail, the whole indicated by 1 is an accessory of a tire changer, especially for locking the wheel rim of a vehicle.

[0035] Specifically, the accessory 1 can be installed on all conventional tire changing machines that have a rim hub clamping device.

[0036] For example, accessory 1 can be installed in a similar figure 1 On a tire changing machine F of the kind shown briefly in, the tire changing machine F has a known type of spindle A with a taper lock for clamping and placing the rim C of the wheel D during rotation.

[0037] However, it cannot be ruled out that accessory 1 is installed on different types of rim hub clamping devices.

[0038] It should be pointed out that the expression "spindle with cone lock" refers to a conventional type of spindle A, the spindle A includes a plate B for resting the rim C of the wheel D, and the spindle A is passed through a suitable motor device It is rotatably mounted on the base structure E of th...

Abstract

The accessory (1) for tyre-changing machines, particularly for the locking of wheel rims for vehicles, comprises supporting means (2) associable in a removable way with a revolving portion (B) of gripping means of the hub of the rim on a tyre-changing machine, at least two gripping jaws (3) of the rim of a wheel associated with the supporting means (2) and moving along a reciprocal approach and away direction between a position of maximum opening, wherein the gripping jaws (3) are arranged at a preset maximum distance, and a position of minimum opening, wherein the gripping jaws (3) are arranged at a preset minimum distance, and movement means (4) associated with the supporting means (2) and with the gripping jaws (3), suitable for moving the gripping jaws (3) between the position of maximum opening and the position of minimum opening.

Description

Technical field [0001] The invention relates to an accessory for a tire changing machine, particularly an accessory for locking the rim of a vehicle tire. Background technique [0002] The use of the so-called "tyre changing machine" is known, which allows the tire to be mounted on or removed from the corresponding wheel rim, for example for maintenance or replacement of the rim and / or the tire itself . [0003] Such a tire changing machine usually includes: a base structure support device for clamping and placing the wheel rim during rotation, the base structure support device having a locking device for the rim; and at least one tool support arm, the tool support arm having One or more tools suitable for removing the tire from the rim and / or installing it on the rim. [0004] There are currently different types of devices for clamping and placing wheel rims during rotation, which are composed of different types of rim locking shafts. [0005] The first type of device for clamping ...
