Embodiment Construction

[0015] The illustrated embodiment comprises a wheel receiving device 2 to which a rim 3 of a vehicle wheel (rim / tyre assembly) 1 can be fastened. A receiving rod as shown in the figure, a wheel disc on which a rim can be mounted, or a clamp arm for supporting a rim, or other supporting components can be arranged on the wheel receiving device. The wheel rim 3 is non-rotatably connected to the wheel receiving device 2 via a fixing device, in particular a clamping device.

[0016] The illustrated embodiment also includes figure 2 The installation or removal tool 5 is shown schematically in the image 3 The flange cutting tool schematically shown in , when the automobile wheel 1 is placed horizontally, the installation or removal tool and the flange cutting tool are in contact with the sidewall of the tire 4 near the bead 12 from the upper and lower sides, when the automobile tire 4 When it is in the installed position, the bead is located behind the rim flanges 12 on both sides...

Abstract

The invention discloses a method and an apparatus of determining geometrical dimensions of a motor vehicle wheel; in particular, the invention discloses a method and an apparatus of determining geometrical dimensions of a motor vehicle wheel (rim / tyre assembly) (1) by contact-less sensing, wherein the wheel is fixed on wheel receiving means (2) of a tyre changer, that at least one light beam (21) is emitted on to the wheel or at least a part of the wheel, wherein the light beam reflected at the impingement area is detected, and wherein the directions of the emitted and reflected light beams are evaluated for determining the shape and / or position of the respective impingement area on the wheel.

Description

technical field [0001] The invention relates to a method and a device for determining the geometry of a wheel, in particular a method and a device for determining the geometry of a wheel rim. Background technique [0002] US3877505 discloses a device with a wheel receiving device to which the rim of a vehicle wheel can be fastened. The wheel receiving device can be rotated by a rotary drive, such as an electric motor, during a mounting or demounting operation. Tires can be installed or removed from the rim using installation or removal tools. On the dismantling tool there is provided a protruding detection device which can detect the radially outer surface (rim carrier) of the rim and consists of a material which does not damage the material of the rim, for example a plastic material. This ensures that the removal tool can maintain a certain distance from the rim surface during the removal operation. Damage to the rim surface by the hard material of the removal tool can t...
