Abstract
A tire-mounting apparatus for mounting a tire having two beads on a rim in a tire/rim assembly where the rim has two opposed flanges that are bent radially inwards to define a drop center, and where the beads of the tire extend over the rim and are located behind the rim flanges in the drop center. The apparatus includes a base on which a rim-mounting adaptor is rotatably mounted. A clamp is used to retain the beads of the tire on the rim. A mounting tool forces one of the tire beads over one of the rim flanges. The mounting tool is rotatably driven to move the tire and the rim so that the one tire bead is rolled over the one rim flange into the drop center of the rim.
Claims18
A tire-mounting apparatus for mounting a tire having two beads on a rim in a tire/rim assembly where the rim has two opposed flanges that are bent radially inwards to define a drop center, and where the beads of the tire extend over the rim and are located behind the rim flanges in the drop center, said apparatus comprising:
- a base;
- rim-mounting means for rotatably mounting the rim to said base;
- clamping means for retaining the beads of the tire on a radially inner side of the rim flanges;
- mounting means having a mounting tool for forcing one of the tire beads over one of the rim flanges, into the drop center and radially outwards onto said radially inner side of the rim flanges while the beads of the tire are retained by the clamping means;
- moving means for moving the tire and rim when the tire is in contact with the mounting tool and the beads are retained on said radially inner side of the rim flanges by said clamping means so that said one tire bead is rolled over said one rim flange, into the drop center of said rim and forced radially outwards onto said radially inner side of said one rim flange, said moving means including a drive unit for rotating said mounting tool against said tire to move said tire and rim;
- and
- braking means for counteracting the movement of said tire and rim by said moving means, said braking means including an assembly secured to said rim-mounting means.
A tire-mounting apparatus for mounting a tire having two beads on a rim in a tire/rim assembly where the rim has two opposed flanges that are bent radially inwards to define a drop center, and where the beads of the tire extend over the rim and are located behind the rim flanges in the drop center, said apparatus comprising:
- a base;
- rim-mounting means for rotatably mounting the rim to said base;
- clamping means for retaining the beads of the tire on a radially inner side of the rim flanges;
- mounting means having a mounting tool for forcing one of the tire beads over one of the rim flanges, into the drop center and radially outwards onto said radially inner side of the rim flanges while the beads of the tire are retained by the clamping means, said mounting means including means for moving said mounting tool along a displacement axis that is equally spaced from the axis of rotation of said rim-mounting means, and said mounting means including a movable support column whose longitudinal axis coincides with said displacement axis, a clamping plate surrounding a portion of said column, and a pressure-cylinder means for urging said clamping plate into locking engagement with said column;
- moving means for moving the tire and rim when the tire is in contact with the mounting tool and the beads are retained on said radially inner side of the rim flanges by said clamping means so that said one tire bead is rolled over said one rim flange, into the drop center of said rim and forced radially outwards onto said radially inner side of said one rim flange;
- and
- locking means for locking said mounting means at a desired position along said displacement axis.

- a base;
- rim-mounting means for rotatably mounting the rim to said base;
- clamping means for retaining the beads of the tire on a radially inner side of the rim flanges;
- mounting means having a mounting tool for forcing one of the tire beads over one of the rim flanges, into the drop center and radially outwards onto said radially inner side of the rim flanges while the beads of the tire are retained by the clamping means, said mounting means including means for moving said mounting tool along a displacement axis that is transverse to the axis of rotation of said rim-mounting means;
- moving means for moving the tire and rim when the tire is in contact with the mounting tool and the beads are retained on said radially inner side of the rim flanges by said clamping means so that said one tire bead is rolled over said one rim flange, into the drop center of said rim and forced radially outwards onto said radially inner side of said one rim flange;
- locking means for locking said mounting means at a desired position along said displacement axis;
- and
- said mounting means including a movable, elongated arm on one end of which said mounting tool is mounted, said movable arm having a longitudinal axis that coincides with said displacement axis, and wherein said locking means includes a clamping plate surrounding a portion of said arm, and a pressure-cylinder means for urging said clamping plate into locking engagement with said arm.
