A method for recognizing a rail vehicle wheel as well as an arrangement for recognizing a rail vehicle wheel. A specific detection pattern of the rail vehicle wheel to be identified is ascertained using rollover signal of a rail vehicle wheel to be identified, which is ascertained with the aid of a load measuring device arranged on a rail, the rollover signal describing a time characteristic of a rail load induced by the rail vehicle wheel to be identified on the rail equipped with the load measuring device during the rollover, and the specific detection pattern comprising one or multiple identification parameter(s)/characteristic value(s) ascertained using the rollover signal. The ascertained specific detection pattern of the rail vehicle wheel to be identified is compared with one or multiple predefined reference-specific detection pattern(s) of rail vehicle wheels, and the rail vehicle wheel to be identified is identified by the comparison.

A system for monitoring the state of a wheel of a rail vehicle includes an acquisition unit that is designed, upon a braking event, to acquire at least one operating parameter for the wheel, an evaluation unit that is designed to determine a temperature value for the wheel based on the acquired operating parameter; and a control unit that is designed to generate and to output an output on the basis of the determined temperature value. It furthermore relates to a method for monitoring the state of a wheel of a rail vehicle, in which, upon a braking event, at least one operating parameter for the wheel is acquired, a temperature value for the wheel is determined based on the acquired operating parameter and an output is generated and output on the basis of the determined temperature value.

An apparatus and method for calibrating and/or adjusting a force transducer or accelerator sensor of a measuring apparatus. The apparatus including a force spring element fixedly connectable to the measuring apparatus, a mass body movable along a guide relative to the force application element and a reference force transducer or reference acceleration sensor arranged between the force application element and the mass body. A positive or negative acceleration is applied to the mass body and the reaction forces resulting from the acceleration of the mass body are applied to the force-application element and, additionally, to the force transducer or acceleration sensor in the measuring apparatus. Values determined by the reference force transducer or reference acceleration sensor and the values determined by the force transducer or acceleration sensor in the measuring apparatus are recorded, processed and compared.

The present disclosure generally relates to a bearing hub assembly of a rail guide wheel apparatus for a rail vehicle. The bearing hub assembly may couple rail wheels to the rail guide wheel apparatus. The rail guide wheel apparatus may be included on a Hi-Rail vehicle or any other vehicle configured to travel along railroad tracks. The bearing hub assembly includes a sensor that is integrally mounted within the bearing hub assembly. The sensor collects information associated with rotation of the rail wheels. Information collected by the sensor may be used to determine a speed, direction, location, and/or distance traveled of the rail vehicle.
