Sistema e metodo per determinare una coppia di frenata mediante dispositivo di rilevazione di una forza ad un'interfaccia tra pinza freno e portamozzo

A detection device for detecting a braking force applied by a brake caliper on a hub holder is configured to be mounted at a fastening interface between the brake caliper and the hub holder and has a low-friction body, a caliper- hub-holder connection element, a sensor element, and an electrical interface. The low-friction body puts into contact the brake caliper and the hub holder at the fixing interface. The caliper- hub-holder connection element, configured to be mechanically connected to the brake caliper and the hub holder, is susceptible of deformation. The low-friction body decouples tightening forces from the braking forces to minimize the effect of the tightening forces on the detection device. The sensor element detects strains and generates electrical signals indicative of detected strains and representative of the braking force. The electrical interface is connected to the sensor element for conducting and making available the generated electrical signals. A method and a system for determining a braking torque are also provided.
