摘要
The quality of rail wheels still attached to a rail vehicle or removed from the rail vehicle, is automatically monitored and measured for correction purposes as a rail vehicle or even an entire train passes through a measuring range. The measuring range includes auxiliary rails providing a running or reference plane, at least one diameter sensing device and at least one wheel tread profile quality sensing device. Both sensing devices can perform their function while a wheel or wheels are travelling through the measuring range. Signals provided by the sensing devices are supplied to signal processing and evaluating circuits which may provide a signal record and/or control signals for a wheel truing operation.
