Abstract

"DEVICE TO CONTROL THE TEMPERATURE OF THE BEARINGS OF THE WHEEL SETS OF RAILWAY VEHICLES, ESPECIALLY", characterized in that for the reading of the signals a differential value is taken or constitutes from the measurement data, obtained by two temperature sensors at least arranged separately from each other, of which one is located on the outer washer of the bearings of each set of wheels, while the other is placed on a part of the vehicle that is exposed to external temperature, whose surface/volume ratio must correspond, more or less approximately, to that of the wheelset bearing housing, and since these sensors are two of the resistance branches of a connection or bridge mounting, which it is in turn connected to at least two limit value switches, and those that due to the corresponding adjustment in the temperature control emit a signal warning when a first temperature limit is reached and then an alarm signal when a second limit is reached, being especially applicable to high-speed rail vehicles, for which purpose they have temperature sensors that constantly take the of the bearings, and when they exceed certain limit values they emit the indicated signals.
