Patent ID: 7746456

Claim:
An alignment measurement apparatus for contactless measuring alignment of a vehicle wheel, the apparatus comprising: a support at which a carrier is rotatable mounted about a rotation point; at least one measuring unit mounted to the carrier such that the measuring unit has a defined geometrical position and configured to measure distance data of a measurement point on the wheel from the respective measurement unit in a contactless manner, wherein the measuring unit being pivotable about an axis, parallel to a reference plane corresponding to a rotation plane of the carrier device about the mounting point and orthogonal to an radius from the rotation point to the measuring unit; control means configured to control rotation of the carrier device and pivoting of the at least one measuring unit such that a measurement point is on the wheel in the area of the bead of the rim; and processing means configured to calculate wheel alignment data from the provided measured distance data of at least three measurement points together with the respective geometrical position and a respective pivoting angle of the respective at least one measurement unit, and a respective rotation angle of the carrier.
