METHOD FOR MANUFACTURING A BRAKING ELEMENT WITH INTEGRATED SENSOR, IN PARTICULAR A BRAKE PAD, BRAKE PAD WITH INTEGRATED SENSOR, VEHICLE BRAKING SYSTEM AND ASSOCIATED METHOD |
摘要 |
A method in which at least one piezoceramic sensor, which converts every mechanical force to which it is subjected into an electrical signal and having a Curie temperature higher than 200° C., is solidarized directly onto the surface of a metal support element of a vehicle braking element, which during use faces a vehicle element to be braked. While in contact with such a surface, an electrical circuit is implemented that picks up and eventually processes the electrical signal, the electrical circuit being connected with a connector integrated with the metal support element. An electrically insulating layer sandwiches the at least one piezoceramic sensor and the electrical circuit, and a block of friction material with an underlying damping layer is formed upon the electrically insulating layer. After forming the block of friction material, the piezoceramic sensor is polarized by applying a predetermined potential difference thereto by means of the connector. |
