Abstract:
A measuring and transmitting bolt or threaded element for a railway bogie comprises a head defined in which is a seat, and a threaded stem defined in which is a hole, a miniaturized vibration sensor, a transmitter, a battery for supplying said MEMS vibration sensor and said transmitter, and a miniaturized converter for converting into electrical energy the mechanical energy from the vibrations in order to recharge the battery. In particular, the transmitter and the vibration sensor are housed in the seat, and the miniaturized converter and the battery are housed in the hole.
