    Abstract: A vehicle braking system includes a controller that receives signals from sensors associated with vehicle disc brakes, which allow detection of a parameter indicative of a degree of noise generated from each disc brake. When noise generation is detected, the controller activates a noise attenuation function of a first type if the vehicle is braking, and of a second type if the vehicle is not braking. The first type involves reducing actuating pressure of a fluid actuator associated with the disc brake for which noise generation is detected. The second type involves temporarily activating, while the vehicle is running and not braking, the fluid actuator associated with the disc brake which is generating noise. The controller also receives signals indicative of vehicle operating parameters which allow conditions to be defined in which priority is given to vehicle safety, and in which the noise attenuation function is excluded.

    Abstract: An anti-loosening device for a fastening unit of a motor-vehicle wheel is configured to be coupled with a wheel hub. The anti-loosening device is configured to be arranged within the wheel hub along an axial direction, so that a main axis of the anti-loosening device coincides with the wheel axis. The anti-loosening device includes a gear arranged to cooperate with inner teeth of the wheel hub, an elastic element extending axially with respect to the gear, and a coupling element obtained on a sector of said gear, arranged to receive a corresponding fastening. During assembly of the wheel—hub assembly, the anti-loosening device is arranged to create a compressed configuration, wherein the gear is decoupled with respect to the inner teeth, and is arranged within a cavity portion obtained on the inner surface of the wheel hub, so as to allow rotation of the anti-loosening device around the main axis.

    Abstract: A tool for mounting a motor-vehicle wheel on a wheel hub includes a tubular body having a coupling portion arranged for coupling to the wheel hub, and a carrier portion for supporting the motor-vehicle wheel during a centering phase of the wheel on the hub. The tool has an inner tubular member and an outer tubular member rigidly connected to each other so as to be coaxial. At the coupling portion, the inner and outer tubular members are spaced apart so as to define a space arranged to receive an end portion of the wheel hub, in such a way that, in an operating condition, the end portion of the hub is interposed between the inner tubular member and the outer tubular member.
