Abstract: A device for detecting the clamping force of a brake caliper of a vehicle braking system comprises a force sensor, a force transmitting element suitable to transmit a clamping force exerted by the brake caliper to the sensor, and a limit stop element. The transmitting element is movable when subjected to a clamping force exerted by the brake caliper. The force sensor is configured to measure a clamping force up to a sensor force threshold value which is lower than the maximum clamping force exertable by the caliper. The mechanical limit stop element is configured to be engaged by the force transmitting element when the clamping force exceeds the sensor force threshold value.

Abstract: An actuating device (1) for a disc brake (2), comprises a piston (7), a first ramp-ball motion converter (100), having a first ramp portion (101) axially constrained and actuatable in rotation around the actuating axis (8), a second ramp portion (102) coupled to the piston (7) and a plurality of rolling elements (29) interposed in contact between ramp tracks (103) formed by the first (101) and second ramp portion (102), a second screw and nut motion converter (4), connected between the second ramp portion (102) and the piston (7), a torque limiter (10) that: - implements a torsional connection of the first ramp portion (101 ) with the second ramp portion (102), so that they rotate together about the actuating axis (8) until a predetermined limit torque in said torsional connection is reached, - decouples the rotation of the first ramp portion (101) with respect to the second ramp portion (102) about the actuating axis (8) when the predetermined limit torque is exceeded.
