Abstract: The invention relates to a device for measuring the geometry of a wheel axle of a motor vehicle, said device comprising a hub gripping element (20) for gripping and rotating a hub (50) of the wheel axle, and at least one measuring sensor (58). The invention also relates to a method using said device. The aim of the invention is to create one such device and one such method which enable measuring values to be much more precisely recorded. To this end, the hub gripping element (20) comprises at least one stud (42, 44, 46) that can be screwed into a threaded borehole on the hub (50) or the brake disk (62) in order to fix the wheel axle to the hub gripping element (20).

Abstract: The invention relates to a device for measuring the geometry of a wheel axle of a motor vehicle, said device comprising a clamping chuck (56) which is provided with clamping jaws (32, 34, 36) and is used to receive a hub of a wheel axle, and a drive for rotating the clamping chuck (56). In order to increase the measuring precision, the drive is embodied as an electric drive, especially as a servomotor, and both rotatably drives the clamping chuck (56) and actuates the clamping jaws (32, 34, 36) of the clamping chuck (56) in the radial direction. Furthermore, according to the invention, the clamping jaws are radially displaced by means of a link motion with an eccentric plate or a spiral motion with a spiral of Archimedes in such a way as to obtain an automatic lock.
