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.

Abstract: A vehicle braking system includes an assistance device, having a vacuum pump driven by an engine for communicating vacuum to a chamber of the assistance device. A control valve is interposed along a fluid line between the pump and the chamber. The control valve is in its first operative condition, where the inlet side of the vacuum pump communicates with the chamber, when the pressure within the chamber is above a predetermined value; and is in its second operative condition, where the inlet side of the vacuum pump communicates with the atmosphere, when pressure within the chamber is below a predetermined value. In this second condition the pump intakes air from and feeds air into the atmosphere, thereby reducing the energy consumption by the engine required for driving the pump during stages where, within the chamber there is a vacuum sufficient for the regular operation of the braking system.
