Abstract: Method and plant for manufacturing braking elements such as vehicle brake pads. The plant can comprise a first station that applies an adhesive to a first face of a metallic element; a second station that applies to the first face of the metallic element a block of friction material; a checking station that verifies the presence of the adhesive by detecting the gray level of a plurality of points of at least one zone of the first face; and a processing unit that compares the gray level detected for each point with a first threshold value, counts the number of points that have a gray level that satisfies a relationship (which is a function of the threshold value,) and compares such a value with a second threshold value to discard those metallic elements for which the percentage calculated does not correspond to the second threshold value.

Abstract: 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.

Abstract: Various braking devices, systems, and methods are disclosed. In some embodiments, the braking device includes a support element, a block of friction material supported by the support element, at least one piezoceramic sensor supported by the support element and interposed between the block of friction material (and the support element, and a protective element located at the piezoceramic sensor and embedding the latter. The protective element can have one or more layers of resin-based material applied to protect the piezoceramic sensor and direct a predetermined part of the external compression force onto an area of the support element surrounding the piezoceramic sensor. In some embodiments, a signal transduction device is provided and includes at least one piezoceramic sensor supported on a support element and has an integral protective coating having properties of mechanical and temperature resistance.

Abstract: A brake element is sensorized by at least one piezoceramic sensor arranged between a metallic support element and a block of friction material of a brake element, the sensor being completely embedded within the block. An electrical voltage signal generated by at least one piezoceramic sensor, without the need for a power supply, is picked up by an electrical circuit integrated into the metallic support element. The electrical voltage signal is processed in the form of equal length of samples per unit of time of the detected signal by successively processing in real time each sample of equal length of time sample of the signal by applying an algorithm. The algorithm is selected from at least one of a sequence of integrations of voltage values in the sample carried out in an interval of time in the order of milliseconds; FFT voltage data sample; and integral of the voltage data sample.

Abstract: A method and plant for the thermal treatment of friction elements including a convective heating step which is performed within a convective tunnel oven. The friction elements are arranged laid, in an orderly manner, upon a plurality of trays each tray having a perforated resting plate upon which the friction elements are laid in a position next to one another only, but not overlapped. The trays are piled on top of each other whilst being kept distanced from one another in a stacking direction by an amount that is greater than the thickness of the friction elements. Groups of piled up trays containing the friction elements are arranged side by side on belt conveyor means that pass through the tunnel oven in order to transport the friction elements therethrough.
