Embodiment Construction

[0015] attached figure 1 A wheel 1 is shown in cross section, consisting of a rim 2 and a tubeless tire 3 . The tire 3 has two tire beads 4 , 5 surrounding the counter surfaces 6 , 7 on the outer circumference of the rim 2 . In the axial direction, the tire bead 4, 5 bears on the annular wall 8, 9 of the rim 2, which extends radially outwards adjacent to the mating face 6, 7 and with it towards the mating face 6, 9 The sides of 7 form the contact surfaces for the tire beads 4 , 5 .

[0016] The wheel 1 is mounted on a rotatable spindle 10 . For this purpose, the spindle 10 has a support 11 with a flat radial contact surface and a clamping device 12 which engages in the central bore of the rim 2 , by means of which the rim 2 is precisely centered and torsion-proof. fastened to the spindle 10. The spindle 10 is arranged on a drive motor 13 and can be driven by it.

[0017] Spaced apart from the axis of rotation of the spindle 10 , the sensors 14 , 15 of an optical distance ...

Abstract

The invention relates to a method and a device for checking the seat of a tubeless tire (3) fitted to a rim (2) of a vehicle wheel (1), the vehicle wheel (1) is fastened with its rim (2) centrically on a rotary mount and is rotated about its axis of rotation through at least one revolution. During rotation of the wheel, the outer contours of the radially outer edge areas of the rim (2) and the adjoining areas of the tire (3) are scanned by means of a distance measuring device, and the axial distance differences between the rim (2) and the tire (3) are detected and evaluated.

Description

technical field [0001] The invention relates to a method and a device for checking the fitting condition of a tubeless tire of a wheel on a rim, wherein the rim has at its peripheral edge radially extending annular walls with respect to the axis of rotation, the annular walls facing each other with their The inner side of the tire forms the axial contact surface for the tire bead. Background technique [0002] In the mass production of wheels, the assembly of tires and rims is usually carried out on an assembly line with automation which fits the tires onto the rims, inflates the tires and mechanically balances the assembled wheels. At the end of the assembly line there will be an inspection device that checks the tire tread for radial runout and also checks the tire sidewall for end runout. In practice, however, the problem always arises that a wheel that has been perfectly mechanically balanced and checked and measured is still unbalanced after the wheel has only traveled...
