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
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.

We claim: 1. A device for measuring the geometry of a wheel axle of a motor vehicle, with a clamping chuck (56) comprising clamping jaws (32, 34, 36) for receiving a hub of the wheel axle, with a drive for rotating the clamping chuck (56), characterized in that the drive is configured to be an elec
We claim: 1. A device for measuring the geometry of a wheel axle of a motor vehicle, with a clamping chuck (56) comprising clamping jaws (32, 34, 36) for receiving a hub of the wheel axle, with a drive for rotating the clamping chuck (56), characterized in that the drive is configured to be an electric drive, more specifically 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. 2. The device as set forth in claim 1, characterized in that the electric drive is disposed axially centrally behind the clamping chuck (56). 3. A device for measuring the geometry of a wheel axle of a motor vehicle, with a clamping chuck (56) comprising clamping jaws (32, 34, 36, 76, 78, 80) for receiving a hub of the wheel axle, with a drive for rotating the clamping chuck (56), characterized in that the clamping jaws (32, 34, 36, 76, 78, 80) are radially movable through a link motion control unit (38) or through a spiral motion control unit (70), with the link motion control unit (38) and the spiral motion control unit (70) being actuatable through an electric drive. 4. The device as set forth in claim 3, characterized in that the link motion control unit (38) or the spiral motion control unit (70) is self-locking. 5. The device as set forth in claim 3, characterized in that the spiral motion control unit (70) comprises a spiral of Archimedes. 6. The device as set forth in claim 3, characterized by at least one, preferably three, measuring sensors (58, 60, 62), at least one measuring sensor (58, 60, 62) being brought into abutment with a brake disk and/or with the hub during measurement. 7. The device as set forth in claim 6, characterized in that the at least one measuring sensor (58, 60, 62) is substantially disposed beside the hub gripper (20). 8. The device as set forth in claim 6, characterized in that the at least one measuring sensor (58, 60, 62) is retained so as to be movable in the longitudinal direction.
