Abstract: Hybrid or fully electric vehicle comprising: a conventional braking system based on friction bodies to brake the motor vehicle by interaction of the friction bodies in response to the operation of a brake pedal or any other equivalent control member, a reversible electric machine operatively coupled to the wheels of the vehicle and electronically controllable to operate selectively as an electric engine to generate a mechanical power to propel to the vehicle and as an electric generator to convert the kinetic energy of the motor vehicle into electrical energy, and an automotive electronic control system comprising a sensory system to measure automotive quantities, and an electronic control unit to control operation of the conventional braking system and of the electric machine in response to the operation of the brake pedal or any other operationally equivalent control member. The electronic control unit is further configured to control operation of: the electric machine to selectively perform one or more functions including regenerative braking, in which the electric machine is operated as an electric generator to recover the kinetic energy of the motor vehicle during braking and convert it into electrical energy, and the conventional braking system to clean the friction bodies of the conventional braking system based on the number of brakings performed by the conventional braking system and counted starting from the start-up of the motor vehicle.

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 brake disc for motor-vehicle disc brakes, includes a body with a hub and two opposite annular planar faces, wherein at least one of these faces is formed with one or more lines defining a surface irregularity, in the form of grooves or ribs, which extend between a radially inner edge and a radially outer edge of the respective face, so as to substantially cover the entire radial extension of the face. A height of the surface irregularity along said lines is less than 0.30 mm, so that during use, the lines defining the surface irregularity disappear, due to wear of the respective face, after an initial fraction of the life of the brake disc. During this initial stage, the lines defining the surface irregularity reduce the time necessary to obtain a bedding of the disc brake with respect to a case of a brake disc devoid of the lines.

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.
