Abstract

In a method for advance indication of the possibility of damage occurring to wheel bearings of vehicles, particularly railroad vehicles, the temperatures of the wheel bearing sets of a plurality of wheels are monitored by temperature detectors fixedly mounted on the vehicle. A determined value is derived from the measured values of temperature, and this determined value is compared with the temperature of a further temperature detector, in order to produce a warning signal. The warning system is incorporated in the vehicle itself, and provides a warning to the vehicle personnel.
