Abstract
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.
Claims13
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.
1 more element
A method for the estimation of the state of efficiency of a tensioner, the method comprising:
- acquiring data relating to operating parameters from the sensor means arranged on the tensioner;
- calculating a plurality of quantities representing the state of efficiency of the tensioner on the basis of the acquired data;
- comparing said calculated quantities with stored threshold values;
- and
- activating a signal if said comparison determines a condition of inefficiency of the tensioner.
