Abstract: Various machines, systems, and methods for generating calibration data for a sensorized brake pad are disclosed. In some embodiments, a system includes a fixture, a brake pad retainer, a pressure plate, an actuator and a controller. The actuator applies a pressure to the sensorized brake pad and signals from the pressure sensors are received. Calibration data is generated based on the signals received from the pressures sensors when the pressure is applied to the sensorized brake pad.

Abstract: Method for manufacturing an asbestos-free friction material having as component materials inorganic and/or organic and/or metallic fibers, at least one organic binder, at least one friction modifier or lubricant and at least a filler or abrasive. The raw components of the friction material are mixed together to obtain a raw mixture which is then molded to obtain a block or layer of friction material. The mixing step includes a first step of hot blending of at least part of the organic binder with at least part of the other components of the friction material by a rolling mill blender that is open to atmospheric pressure at a temperature lower than the polymerization temperature of the organic binder but greater than or equal to its softening temperature, in order to obtain a semifinished solid product. A second step of grinding the semifinished solid product reduces the product to a powder.

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: Braking system (1) and method aimed to produce a forced increase in a damping layer (7) temperature of a brake pad (3), arranged between a metal support (5) and a friction material block (6) thereof, wherein the damping layer (7) is heated such as to stay at a temperature above a glass transition temperature of rubber components thereof, so assuring a maximum damping behavior; the heating is caused by magnetic induction generated by one or more electrically conducting coils (15) fed in AC by a power source (10) carried by the vehicle and arranged either integrated in the brake pad (3), e.g. carried by the support (5), or in the vicinity thereof.

Abstract: Methods and equipment for determining conditions of adhesion between a first and a second mechanical element are disclosed. The mechanical elements are attached respectively to a first and second support, which are immersed in an electrolyte together with a counter-electrode and a reference electrode to form an electrochemical cell. The second mechanical element is a working electrode being connected to an insulated electric wire that is also connected to the counter-electrode. A first uncovered face of the second element is pressed against the first element. A potential is applied to the second element of at least one predetermined value and/or a predetermined electrical current. The method can include detecting the electrical current that is transmitted through the electrolyte as a function of the potential applied and/or the potential that is established as a function of the predetermined current.

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.
