Abstract
A temperature indicator is mounted within a wheel hub to generate a warning signal when a wheel end component overheats. The temperature indicator comprises a thermal battery that is activated only when the wheel end component exceed a predetermined temperature. Once activated the battery powers an RF transmitter to generate a wireless warning signal that is transmitted to a remote receiver to display a warning.
