Abstract
A method of and an apparatus for fitting or removing a tire 4 of a vehicle wheel 1, in which at least one fitting or removal tool 5 is guided parallel to the axis 11 of the vehicle wheel 1 and the vehicle wheel 1 is moved controllably perpendicularly to its wheel axis 11 in dependence on a rim contour along which the fitting or removal tool 5 is to be guided at a small spacing.
Claims22
A method of fitting a tyre on to a rim of a vehicle wheel or removing a tyre from a rim of a vehicle wheel, in which at least one fitting or removal tool is moved controlledly past a rim flange of the rim without touching the rim flange, wherein:
- the at least one fitting or removal tool performs movement only in a parallel relationship with the axis of the vehicle wheel, and
- while the at least one fitting or removal tool performs movement only in the parallel relationship with the axis of the vehicle wheel during the fitting or removal operation, the vehicle wheel is controlledly moved perpendicularly to the axis of the vehicle wheel in dependence on a rim contour of a rim portion, along which the fitting or removal tool is guided.
An apparatus for fitting a tyre on to a rim of a vehicle wheel or for removing a tyre from a rim of a vehicle wheel, comprising at least one fitting or removal tool, at least one sensing device, a control device, and a drive device to move the at least one fitting or removal tool, wherein:
- the sensing device is adapted to sense a rim contour at least in the region along which the fitting or removal tool is guided,
- the drive device is configured such that the at least one fitting or removal tool moves only in a parallel relationship to the axis of the vehicle wheel, and
- the control device is configured to control the movement of the vehicle wheel such that while the at least one fitting or removal tool performs movement only in the parallel relationship with the axis of the vehicle wheel during the fitting or removal operation, the vehicle wheel is moved perpendicularly to the axis of the vehicle wheel in dependence on the rim contour, along which the fitting or removal tool is guided.
