Mounting device for motor vehicle tires

A mounting apparatus for motor vehicle tires having beads and side walls and mounted to a wheel rim having a horn portion, said apparatus comprising:

• a base;
• a bearing support mounted to said base and having an upwardly extending axis and a rotationally driven holder for clamping the tire rim thereto;
• a stand upwardly projecting from said base;
• a pressure device mounted on said stand, said pressure device being adapted for applying pressure sufficient for pressing the tire bead away from the horn of the wheel rim;
• two motor-driven telescopic arms, each said telescopic arm having a base portion coupled at the proximal end to said pressure device and having an extensible portion fitted telescopically to said base portion, said each telescopic arm being adjustable in length;
• a pressure element coupled to the distal end of each said telescopic arm adapted to act on a tire wall next to the horn of the wheel rim;
• a column mounted to said stand and having a generally upwardly projecting axis;
• sliding bushings on said column, the proximal ends of each said telescopic arm being pivotably connected to a respective said sliding bushing, said sliding bushings guiding said telescopic arms in motion toward and away from each other;
• a motor drive for applying force sufficient for pivoting said telescopic arms on said sliding bushings;
• a linear drive coupled to said motor drive and pivotably coupled at the proximal end to each said respective sliding bushing, each said linear drive having a linearly moving element coupled to said base portion of said respective telescopic arm for adjusting the linear and angular displacement of said respective telescopic arm with respect to said column;
• and
• a coupling element mounted to each said moving element for engaging said extensible portion of said respective telescopic arm when said respective linear drive is activated.
