Abstract
A tire changing machine having a support frame, rotatable supporting device for a wheel rim, locking device for securing the wheel rim to the supporting device, a fitting tool which can be secured to an adjustable tool supporting arm carried by the support frame, and driving device for the rotatatable supporting device. The machine also includes a first and a second pressure members which can be located in diametrically opposite positions with respect to a wheel rim carried by the supporting device and are designed to act on either side of a tire on the wheel rim, and drive device for actuating, upon control, each of the first and second pressure members.
Claims15
A tire changing machine having a support frame, rotatable supporting means for a wheel rim, locking means for securing said wheel rim to said supporting means, a fitting tool securable to an adjustable tool supporting arm carried by said support frame, and driving means for said rotatable supporting means, and wherein it has at least one first and second pressure members which can be located in diametrically opposite positions with respect to a wheel rim carried on said supporting means and are arranged to act on opposite sides of a tire on said wheel rim, and drive means for actuating, upon control, each said first and second pressure members.
A tire changing machine having a support frame, rotatable supporting means for a wheel rim, locking means for securing said wheel rim to said supporting means, a fitting tool securable to an adjustable tool supporting arm carried by said support frame, and driving means for said rotatable supporting means, and wherein it has at least one first and second pressure members which can be located in diametrically opposite positions with respect to a wheel rim carried on said supporting means and are arranged to act on either side of a tire on said wheel rim, and drive means for actuating, upon control, each said first and second pressure members, said supporting means comprising a rotatable mandrel assembly, and said rotatable mandrel assembly having a substantially horizontal axis.
A method for bead breaking and removing a tire secured to a rotating support from a wheel rim, comprising:
- applying to said tire at least one pair of head breaking pressure members arranged diametrically opposite to, but acting on opposite sides of, the tire;
- causing the tire to rotate while said bead breaking pressure members press onto mutually opposite and offset positions of said tire faces whereby breaking each tire bead simultaneously on both sidewalls or faces thereof;
- and
- turning off any pressing action of one of said bead breaking pressure members while the other one goes on pushing against the tire until removal from said wheel rim is completed.
