Mounting device, and method for mounting and dismounting a vehicle tire on and from a rim

A mounting device for mounting or dismounting a vehicle tire on a wheel rim, the wheel rim being supported on a mounting table, and a pressing-down device being provided for sliding the vehicle tire on the wheel rim, the pressing-down device has movement essentially parallel to the tire axis for sliding the vehicle tire on the wheel rim or pulling off the vehicle tire from the wheel rim.

A mounting system comprising a mounting device for mounting or dismounting a vehicle tire on a wheel rim, the wheel rim being supported on a mounting table, and a pressing-down device being provided for sliding the vehicle tire on the wheel rim, whereas movement of the pressing-down device which is essentially parallel to the tire axis for sliding the vehicle tire on the wheel rim or pulling off the vehicle tire from the wheel rim and a mounting table as well as a pushing device shifting the vehicle tire to be mounted on a wheel rim with respect to the wheel rim in such a way that a part of the tire bead positioned on the wheel rim gets in the drop base of the wheel rim.

A pressing-down device, being a part of a mounting system comprising a mounting device for mounting or dismounting a vehicle tire on a wheel rim, the wheel rim being supported on a mounting table, and a pressing-down device being provided for sliding the vehicle tire on the wheel rim, whereas movement of the pressing-down device is essentially parallel to the tire axis for sliding the vehicle tire on the wheel rim or pulling off the vehicle tire from the wheel rim and a mounting table as well as a pushing device shifting the vehicle tire to be mounted on a wheel rim with respect to the wheel rim in such a way that a part of the tire bead positioned on the wheel rim gets in a drop base of the wheel rim for fixing the bead during mounting, where at least the area interacting with the vehicle tire consists of a synthetic or rubber material.

A method for mounting a vehicle tire on a wheel rim, a vehicle tire being at least partly on a wheel rim, where a bead is at least partly above the wheel flange, including the steps of shifting the vehicle tire by a pushing device relatively in such a way radial to the wheel rim to press a part of the bead in the drop base of the wheel rim, and, then pressing, the bead area still in front of the wheel flange by an essentially rectangular movement with respect to the wheel rim over the wheel flange into the wheel rim.

A method for dismounting a vehicle tire from a wheel rim including in sequence the following steps:

• radial shifting of the vehicle tire relative to the wheel rim, for example by arranging and tensioning a belt along the tread of the vehicle tire, at least along a part of the tread of the tire, so that a part of the bead of the tire is pressed into a drop base of the wheel rim;
• pressing another area of the bead out of the wheel rim beyond the wheel flange by an essentially rectangular movement with respect to the wheel rim.
