Abstract: A steering suspension of a vehicle includes a suspension upright and a mechanical component consisting of a radially outer ring of a wheel hub unit or of a rolling bearing forming part of a wheel hub unit. The outer ring is provided integral in one piece with a flange and a steering arm, extending radially cantilevered from the outer ring and the flange, with which it is also integral in one piece. On the side opposite to the steering arm the flange is integral in one piece with a pair of axially drilled radial lugs, configured to support, in use, a brake caliper.

Abstract: A suspension device of a motor-vehicle wheel includes a support member of the motor-vehicle wheel connectable to the motor-vehicle structure by means of one or more suspension members, a brake disc connected in rotation with the motor-vehicle wheel, a brake caliper associated with the brake disc and a brake disc cover. The brake caliper is formed in a single piece with the support member of the motor-vehicle wheel by means of additive manufacturing technology.

Abstract: Steering suspension module including a shock absorber strut, a suspension upright, an outer ring of a wheel hub unit attached integrally to a front face of the suspension upright, and a ball joint for articulation with a control arm; wherein the suspension strut consists of a cup-shaped body made entirely of continuous, sheared and bent metal sheet, and the outer ring is provided integral in one piece with, and radially cantilevered from, a steering arm extending transversely cantilevered from the cup-shaped body, on the side of the cup-shaped body; the shock absorber strut is constrained within a first seat of the cup-shaped body and the ball joint is made as an independent unit constrained integrally with a second seat of the cup-shaped body in a position facing the first seat, the ball joint projecting inferiorly cantilevered from the cup-shaped body.

Abstract: A motor-vehicle wheel support unit includes a first base body provided with attachments for connection to arms of a motor-vehicle suspension, and a second body for rotatably supporting a wheel hub, which is separate with respect to the first base body and is secured to the first base body in one of two different selectable mounting positions, which correspond to two different vertical positions, with reference to a condition of use, of an axis of the wheel hub with respect to the first base body. In this manner, a height of the vehicle from the ground can be modified by simply mounting said second body on the first body in one or the other of the two mounting positions. In each of the two mounting positions, the second body is rotated by 180° around an axis parallel to the wheel hub axis with respect to the other mounting position.

Abstract: A suspension device of a motor-vehicle wheel includes a support member of the wheel connected to a structure of the motor-vehicle by one or more suspension members and a brake disc connected in rotation with the motor-vehicle wheel. The device also includes a brake disc cover rigidly connected to the support member and at least partially surrounding the brake disc. The brake disc cover is formed in a single piece with said support member of the motor-vehicle wheel.

Abstract: It is herein described an oscillating arm for a motor-vehicle suspension having a first rod element and a second rod element. The second rod element is a half-shell rod that provides a cavity. The oscillating arm also comprises at least one insert, made of plastic or fiber-reinforced composite material, which fills the cavity of the half-shell rod.

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.
