    Abstract: An auxiliary cross-member structure for supporting elements of a motor-vehicle front suspension includes a metal sheet hollow frame in a form of a hollow shell, with two opposite end portions, for connection of two respective oscillating arms of the suspension. The metal sheet hollow frame is defined by a single metal sheet folded on itself and having portions which are overlapped and welded. In a preferred implementation, within the metal sheet hollow frame is provided an additional filling structure at least partially constituted of synthetic material or composite material incorporating reinforcing fibers. At each end of the auxiliary cross-member structure there are two pairs of holes aligned with each other along two vertical axes which are used both for mounting elastic bushings for connection of a respective oscillating arm, and for the engagement of connecting screws for connecting the auxiliary cross-member structure to the motor-vehicle body.

    Abstract: Described herein is a structure of a motor-vehicle door including a multi-thickness metal sheet pressed and shaped to define: a hinge area configured for fastening one or more hinges for connection to the body of a motor vehicle; a panel area configured for receiving an upholstery-trim element for the door; and a frame area configured for receiving a window of the door. The above multi-thickness metal sheet has a first thickness in said hinge area, a second thickness in said panel area, and a third thickness in said frame area.

    Abstract: Described herein is a method for rolling metal sheets of variable thickness. The method makes it possible to impress, during rolling, any distribution of areas of increased thickness within a figure corresponding to the plane development of a motor-vehicle component prior to the pressing operation. Impression of the desired distribution of areas of increased thickness envisages simultaneous impression, during rolling, of a further distribution of areas of increased thickness, or compensation areas.

    Abstract: Described herein is a gearbox for a motor vehicle including a plurality of forward gear ratios and a reverse gear ratio, the gearbox further including: a control device (configured for controlling the selection and the engagement of said forward gear ratios and of said reverse gear ratio; and a plurality of engagement devices that can be controlled by means of said control device for engaging the forward gear ratios or reverse gear ratio (RM) of the gearbox that are operatively associated to said devices. The gearbox includes a locking device, which is electrically controlled and configured for preventing actuation of the engagement device associated to a predetermined forward gear ratio, said locking device being configured for being actuated above a threshold speed of the motor vehicle on which said gearbox is installed.

    Abstract: A welded joint between at least one metal material element and at least one thermoplastic material element is obtained by pressing the elements against each other while applying heat. Contact surfaces of the metal material, which are in contact with the thermoplastic material, are provided with uneven surface portions having a distribution of asperities. With heat applied, the thermoplastic material fills spaces between these asperities and maintains this configuration after subsequent cooling, thereby improving strength of the joint. The uneven surface portions are obtained in a preliminary forming step of the metal material in a press mould, which is configured with a forming surface for generating the uneven surface portions by mechanical deformation and/or with a device for guiding a laser or electron beam. By this technique, hybrid components are obtained made of one or more elements of metal material between which a shaped component of thermoplastic material is interposed.
