A lever device for actuating the parking brake of a motor-vehicle includes a lever structure with a base portion tiltably mounted on a supporting bracket. The mounting includes a first transverse axis, a second transverse axis, a third transverse axis and a fourth transverse axis. When the lever structure is in its completely lowered position, the third and fourth transverse axes are each lower than that of the first and second transverse axes, respectively. In the lowered position, two theoretical planes containing the first and third transverse axes and the second and fourth transverse axes, respectively, intersect along a theoretical axis of instantaneous rotation of the lever structure, which is located above said first and second transverse axes. When the lever structure moves from its completely lowered position to its completely raised position, the lever arm and its end handgrip displace according to a substantially elliptical, and substantially vertically oriented, path, respectively, while the axis of instantaneous rotation of the lever structure moves downwards, following a substantially elliptical path.

An electrical power-steering system for motor-vehicles includes a first pinion and a second pinion meshing with two portions of a rack member which controls the steering angle of the wheels. The two pinions are driven by respective electric motors which are in turn controlled by an electronic control unit. The two portions of the rack member are constituted by two separate elements connected to each other by a connection member interposed therebetween, such that the first and second portions of the rack member behave like a single rigid element when they are driven with identical displacements in a steering maneuver, whereas the connection member allows for a relative movement in the longitudinal direction of the first and second portions of the rack member, with a resulting lengthening or shortening of the rack member, when the first and second portions of the rack member are driven with differentiated displacements in an operative mode for adjustment of the convergence angle of the wheels.

The present invention relates to a gear shift system for a motor vehicle with a steering wheel. Said gear shift system comprises gear shift devices rotationally integral with the steering wheel, each of which is operable by a driver of the motor vehicle to carry out at least one respective gear shift function associated with said gear shift device. Furthermore, said gear shift system further comprises an electronic control unit configured to: receive a magnitude indicative of a current steering wheel angle; determine, on the basis of the received magnitude, whether the current steering wheel angle satisfies predefined conditions; and, if it determines that the current steering wheel angle satisfies the predefined conditions, reconfigure the gear shift functions associated with the gear shift devices.

A motor vehicle has two upper struts, which project forward from a passenger compartment and are arranged above two lower struts, which extend along respective substantially rectilinear axes inclined from the bottom upwards, going forward; the lower struts have respective intermediate portions with such a variation in cross section to define a preferential bending zone; the rear ends of the lower struts are fixed to a cross member connected to the upper struts by means of two connection members, which are substantially vertical and have respective breakable zones designed so as to break when a given load threshold is exceeded; the motor vehicle also has a powertrain connected to the cross member and to the upper struts by means of supports which are distinct from the connection members and are breakable in the event of a front crash.

A motor-vehicle multi-link suspension system includes, for each wheel, two lower transverse arms and a substantially longitudinal or inclined lower arm, each having one end pivotally connected to a respective wheel support and the opposite end pivotally connected to the motor-vehicle structure. A leaf spring is arranged transversally with respect to the longitudinal direction of the motor-vehicle. The leaf spring is supported by elastic supports arranged symmetrically at intermediate positions between the center of the leaf spring and the ends thereof. Ends of the leaf spring are pivotally connected to upper parts of the two wheel supports. Two jack-type shock absorbers have opposite ends swingably connected to the respective wheel support and the motor-vehicle structure. The end portions of the leaf spring also fulfill the function of triangular upper transverse arms of the multi-link suspension. Preferably the leaf spring is made of a composite material.
