Abstract:
1. Apparatus for servicing vehicle wheels including a wheel balancing device and a tire changing device, wherein a spindle shaft is rotatably supported on a machine frame; the spindle shaft is adapted for mounting and dismounting a tire/rim assembly or a wheel rim of a vehicle wheel on it or from it; unbalance measuring means are operatively connected to the spindle shaft; the unbalance measuring means have at least one unbalance measuring direction in which forces created by an unbalance of the tire/rim assembly or by the wheel rim are detected; tire changer tools are supported on the machine frame and adapted to assemble a tire onto a rim and to disassemble the tire from the rim, wherein the rim is mounted on the spindle shaft; spindle supporting means support the spindle shaft on the machine frame with a rigid structure in a force acting range within which forces are created between the respective tire changer tools and the tire during the assembling or the disassembling of the tire onto the wheel rim or from the wheel rim; tool supporting means support the tire changer tools on the machine frame within said force acting range which is arranged outside of a spatial unbalance measuring area within which the measuring directions of the unbalance measuring means extend; drive means are designed to drive the spindle shaft within a range of rotational speed and torque adapted for assembling and disassembling the tire or for measuring forces created by an unbalance of the tire/rim assembly or of the wheel rim.
