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.
Claims15
A track pin assembly comprising:
- a pin comprising 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, wherein the first cavity is open at the first axial end and extends axially towards the second axial end, wherein the first cavity is blind, and a second cavity fluidly separated from said tank, arranged at the second axial end of the pin and open at the second axial end of the pin, wherein the second cavity is blind;
- a sensor arranged in the second cavity and comprising 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;
- and
- a power source configured to supply the sensor and arranged in the second cavity.
A track pin assembly comprising:
- a pin comprising 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 and comprising 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 configured to supply the sensor and arranged in the second cavity;
- and
- a centering ring arranged in the second cavity in an outer axial position with respect to the sensor and to the power source, said centering ring reducing the radial dimension of the second cavity at the second axial end of the pin.
A track pin assembly comprising:
- a pin comprising 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 and comprising 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;
- and
- a power source configured to constantly supply the sensor and arranged in the second cavity;
- wherein the sensor comprises a sensor electronic module operatively connected to the sensor element and to the transmitter to process the signals indicative of the temperature measured by the sensor element and to generate the measuring signals, said sensor electronic module being arranged inside the second cavity and being supplied by said power source;
- wherein the transmitter comprises an antenna and wherein the sensor electronic module comprises a printed circuit board delimited by a peripheral edge, said antenna being assembled on the printed circuit board at the peripheral edge.
