Device for measuring vehicle steering system castor offset has first/second signaling devices that emit optical signals; first signaling device at fixed reference point of scaling arrangement projects optical signal to wheel rotation axis

摘要

The device has first and second signaling devices (2,4) that emit optical signals (8,10). The first signaling device is or can be arranged at a fixed reference point (12) of a scaling arrangement (6) and projects the optical signal to the rotation axis of a wheel (50) of the steering system. The second signaling arrangement can be fixed to the steering system so its projection direction coincides with the steering axis and is essentially directed towards the scaling arrangement.
