Abstract: The present invention relates to a locking device design to act between a tire and its respective wheel rim for dynamically balancing a tired wheel. The locking device is arranged to be installed on a tired-wheel maintenance machine having a support frame and a rotatable support for a wheel rim of a deflated tired wheel and locking-unlocking means for locking-unlocking the wheel rim to and from the rotatable support. The locking device comprises holding belt anchorable to the support frame and an engaging group designed removably to engage the tire of the deflated tired wheel, while its respective wheel rim is controllably angularly shifted.

Abstract: The present invention relates to a bead breaker group for bead breaking a tire of a tired wheel equipped with rim with bead-engagement flanges, the bead breaker group comprising a support (2, 5) and at least one bead breaker tool (3) mounted for rotation around a pin (4) borne by the support (2, 5), the bead breaker tool being substantially flat and comprising: at least one portion configured as an abutment front (3b, 3d, 3f) against a flange of a rim of a tired wheel to be bead broken; and at least one portion having curved peripheral edge substantially coaxial with the pin (4) and intended to act as an engagement-penetration zone (3a, 3c, 3e) between the flange of a rim and the bead of a tire to be bead broken, the distance between the abutment front (3b, 3d, 3f) and the pin (4) being less than the distance between the pin (4) and the at least one engagement-penetration zone (3a, 3c, 3e).
