Abstract: A motor vehicle includes a body, a wheel hub unit, an upright, which is fixed to the wheel hub unit, a fender, which is arranged to cover the wheel hub unit, and a suspension, which couples the upright to the body in a movable manner along at least one axis, which is transversal to a driving direction of the motor vehicle; wherein the suspension comprises at least one movable element, which is movable along said axis, and wherein the fender is carried by said element in a movable manner relative to the body.

Abstract: A car having: a frame; two rear drive wheels; two rear suspensions, which support the two rear wheels; a drivetrain having two axle shafts, which transmit the motion to the rear drive wheels; a rear subframe, which is fixed to the frame in four fixing points through the interposition of elastic isolating elements, directly supports at least part of the drivetrain, and provides a coupling for the rear suspensions. The four fixing points are substantially arranged at the same vertical height. The frame has two “C”-shaped elements, each having its two ends in the area of two fixing points. Two stiffening beams are provided, each arranged longitudinally and screwed to the frame in the area of the ends of a corresponding “C”-shaped element.

Abstract: A method and a plant for the production of a rim for a wheel of a vehicle. At first and by means of an additive manufacturing process, a temporary rim is manufactured, which is provided with a central hub, with a raw ring arranged around the central hub and with a series of spokes, which are radially arranged and connect the raw ring to the central hub; subsequently, the temporary rim is subjected to a flow-forming process, which deforms the raw ring determining an axial lengthening thereof, which transforms the raw ring into a channel having the desired final shape.

Abstract: Power interface control device of a vehicle propulsion battery potential ports to carry out differential potential measurements, a current sensor to measure a current supplied by the propulsion battery and a closed container made of insulating material to which said ports and said sensor are associated, wherein said container comprises connection means to allow a mechanical coupling between the container and said electrical conductor.

Abstract: A process to adjust the ignition timing of an air-fuel mixture in a combustion chamber of an internal combustion engine, the process comprises determining a first quantity indicative of a pressure of the mixture for a cycle of the engine, determining a second quantity indicative of a speed of the engine, determining a third quantity indicative of a first temperature of a conditioning fluid, providing a heat exchange mathematical model for the combustion chamber, which maps the three quantities from the first to the third one onto a fourth quantity indicative of a second temperature of a wall portion around the combustion chamber, estimating the fourth quantity by means of the three determined quantities and by means of the mathematical model, and adjusting the ignition timing as a function of the fourth estimated quantity.

Abstract: Electric machine having: a shaft; a rotor with permanent magnets that is fitted to the shaft; a stator having a magnetic core which consists of a series of laminations made of ferromagnetic material and longitudinally crossed by a plurality of stator slots; and a stator winding having a plurality of rigid bars that are inserted in corresponding stator slots and that are covered, on the outside, with an insulating coating. The rotor has a plurality of magnetic elements, which are arranged beside one another around the rotation axis so as to form a closed ring. Each magnetic element is formed by a plurality of permanent magnets which are axially arranged one after the other according to a Halbach array.

Abstract: A device for the height adjustment of a road vehicle interposed between a frame and a suspension of the road vehicle so as to allow the vehicle to shift from a road configuration to a race configuration and vice versa. The device comprises a base body provided with a first end, which can mechanically be connected to the frame of the road vehicle; a first mass, which can be connected to the base body so as to be movable along a sliding axis; a second mass, which is connected to the first mass so as to be movable along the sliding axis as well and is configured to be able to be connected to a suspension of the road vehicle and to change the stroke of the suspension depending on the position of the second movable mass.

Abstract: A method to control, while driving along a curve, a road vehicle with a variable stiffness and with rear steering wheels. The method comprises the steps of: determining an actual attitude angle of the road vehicle; establishing a desired attitude angle; determining an actual yaw rate of the road vehicle; establishing a desired yaw rate; and changing, in a simultaneous and coordinated manner, the steering angle of the rear wheels and the distribution of the stiffness of the connection of the four wheels to the frame depending on a difference between the actual attitude angle and the desired attitude angle and depending on a difference between the actual yaw rate and the desired yaw rate.
