US 12,637,121 B2 · System and method for monitoring the state of a wheel of a rail vehicle

Abstract

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.

Dependent claims

A system for monitoring the state of a wheel of a rail vehicle, the system comprising:

a recording unit configured to record at least one operating parameter for the wheel in response to a braking event;
an evaluation unit configured to determine a temperature value for the wheel based on the recorded operating parameter;
and
a control unit configured to generate and output an output based on the determined temperature value,
wherein the temperature value determined for the wheel comprises an average temperature of a tread of the wheel and a temperature distribution along the tread of the wheel and a temperature on a contact surface of the wheel.
