Method, apparatus and system for analysing a vehicle wheel
Abstract:
A method of analyzing a vehicle wheel comprising a tire of a predetermined configuration and a thixotropic balancing substance, comprising rotating the vehicle wheel with a predetermined number of revolutions for a period of time, wherein a tread surface of the tire is pressed in a first contact area against a rotatable drum with a predetermined force, and a first acceleration in the first contact area is measured with a measuring device; rotating another vehicle wheel comprising another tire of the predetermined configuration with the predetermined number of revolutions for another period of time, the other vehicle wheel being conventionally balanced and having another residual unbalance, wherein another tread surface of the other tire is pressed in a second contact area against the rotatable drum with the predetermined force, and a second acceleration in the second contact area is measured with the measuring device and if the first acceleration is less than or equal to the second acceleration, determining that the vehicle wheel is balanced. An apparatus, and a system, for analysing a vehicle wheel comprising a tire of a predetermined configuration and a thixotropic balancing substance according to the method.
