Abstract
Official abstract text for this publication.
A tensioner that has a base adapted to be secured to an engine, and at least one arm hinged to a pin fixed to the base and bearing a pulley adapted to cooperate with a belt of a transmission of the engine, and elastic means for pushing the at least one arm in a direction so as to keep the pulley against the belt. The tensioner has sensor means for acquiring in real time a plurality of data relating to the tensioner to estimate the state of efficiency of the same.
First claim
Opening claim text (preview).
The invention claimed is: 1. A tensioner comprising: a base adapted to be secured to an engine, at least one arm hinged to a pin fixed to said base and bearing a pulley adapted to cooperate with a belt of a transmission of said engine, elastic means for pushing said at least one arm in a direction so as to keep said pulley against said belt, and sensor means for acquiring in real time a plurality of data relating to said tensioner to estimate the state of efficiency of the same, wherein said sensor means comprise a temperature sensor and a position sensor for measuring the angular position of said arm with respect to said base. 2. The tensioner according to claim 1 , wherein said temperature sensor measures a temperature of or near said pin. 3. The tensioner according to claim 1 , wherein the temperature sensor is formed by a thermocouple. 4. The tensioner according to claim 1 , wherein said position sensor is carried by said base and interacts with an element carried by said at least one arm. 5. The tensioner according to claim 1 , comprising an electronic circuit connected to said sensor means and provided with means for processing signals generated by said sensor means, and a connector to connect said electronic circuit to a control unit of said vehicle. 6. The tensioner according to claim 1 , comprising a proximity sensor configured to measure the parallelism of said arm of said tensioner. 7. A tensioner comprising: a base adapted to be secured to an engine, at least one arm hinged to a pin fixed to said base and bearing a pulley adapted to cooperate with a belt of a transmission of said engine, elastic means for pushing said at least one arm in a direction so as to keep said pulley against said belt, sensor means for acquiring in real time a plurality of data relating to said tensioner to estimate the state of efficiency of the same, and an electronic circuit connected to said sensor means and provided with means for processing signals generated by said sensor means, and a connector to connect said electronic circuit to a control unit of said vehicle. 8. The tensioner according to claim 1 , wherein said sensor means comprise a temperature sensor and a position sensor for measuring the angular position of said arm with respect to said base. 9. The tensioner according to claim 8 , wherein said temperature sensor measures a temperature of or near said pin. 10. The tensioner according to claim 8 , wherein the temperature sensor is formed by a thermocouple. 11. The tensioner according to claim 8 , wherein said position sensor is carried by said base and interacts with an element carried by said at least one arm. 12. The tensioner according to claim 7 , further comprising a proximity sensor configured to measure the parallelism of said arm of said tensioner.
