1. A device for measuring the geometry of a wheel axle of a motor vehicle comprising: a wheel hub support comprising a wheel hub dome formed correspondingly to an outer side of a wheel hub and encompassing the wheel hub in a precise fit; and means for creating a pressing force acting axially onto the wheel hub dome to press the wheel hub dome against the wheel axle; wherein the wheel hub dome comprises an introduction phase on an inner side of the wheel hub dome; wherein the wheel hub dome forms a bearing surface adjacent to the introduction phase; wherein the introduction phase is inclined by an angle between 30 and 60 degrees relative to a longitudinal axis of the wheel axle and to the bearing surface; wherein the wheel hub dome is configured to grasp the wheel axle via the introduction phase; wherein the wheel hub dome is configured so that the wheel axle is introduced into the wheel hub dome along the introduction phase until a brake disk abuts the bearing surface. 2. The device according to claim 1, wherein the wheel hub support comprises a wheel hub mandrel configured to grasp the wheel hub. 3. The device according to claim 2, the wheel hub mandrel having a side facing the wheel hub, said side comprising a lead-in chamfer configured to grasp the wheel hub. 4. The device according to claim 3, wherein said lead-in chamfer is formed relative to a longitudinal axis of the wheel axle in an inclined manner by an angle between 30 and 60 degrees. 5. The device according to claim 1, wherein the wheel hub support comprises a wheel hub mandrel configured to introduce the wheel hub into the wheel hub dome. 6. The device according to claim 5, the wheel hub mandrel having a side facing the wheel hub, said side comprising a lead-in chamfer configured to introduce the wheel hub into the wheel hub dome. 7. The device according to claim 6, wherein the lead-in chamfer is formed relative to a longitudinal axis of the wheel axle in an inclined manner by an angle between 30 and 60 degrees. 8. The device according to claim 1, further comprising a plurality of segment teeth in the wheel hub dome. 9. The device according to claim 8, wherein the segment teeth are configured to transmit by a positive connection a rotational movement of the device onto the wheel axle. 10. The device according to claim 8, wherein the segment teeth are attached to the wheel hub dome in one piece. 11. The device according to claim 1, further comprising an axially displaceable drive pin that is set apart from the wheel hub support in parallel to a longitudinal axis of the wheel axle. 12. The device according to claim 11, wherein the drive pin comprises a spring that is configured to hold the drive pin in engagement with the wheel axle.
