Chain pin assembly

Abstract

A track pin assembly includes a pin having a first axial end and a second axial end configured to engage a respective outer link of a joint, a first cavity which defines a tank for containing lubricating oil or grease, and a second cavity arranged at the second axial end of the pin and open at the second axial end of the pin. A sensor, arranged in the second cavity, includes a sensor element configured to measure a temperature and to generate a signal indicative of the measured temperature, and a transmitter configured to irradiate a measuring signal that is representative of the signal generated by the sensor element. A power source, arranged in the second cavity, is configured to constantly supply the sensor.
