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.

Suspension device of a motor-vehicle wheel

An on-board centralized system for regulating pressure of tyres of a vehicle includes a pressurized air source, a circuit communicating the source with a plenum of each wheel, and an arrangement for connecting the plenum of each wheel to the inner chamber of the respective tyre that includes first and second connection lines for deflation and inflation, respectively, of the tyre, and first and second one-way valves interposed, respectively, in the first and second connection lines to allow only a flow of air respectively from and to the inner chamber. The first valve includes a spring having a pre-set load so as to isolate the inner chamber from a part of the circuit upstream of the first valve when said upstream part is at atmospheric pressure, and to guarantee a pre-set minimum value of pressure in the inner chamber when the upstream part is at a pressure lower than atmospheric pressure.

On-board centralized system for regulating the pressure of the tyres of a motor-vehicle

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.

An on-board centralized system for regulating pressure of tyres of a vehicle includes a pressurized air source, two pneumatic rotary joints each associated to a driving wheel of the vehicle, and a circuit that sets in communication the pressurized air source with each rotary joint. An output member of a constant-velocity joint and a wheel spindle have an internal duct for air passage, connected to the respective rotary joint and to a plenum of the respective driving wheel. Each non-driving wheel has its wheel spindle traversed by an axial bore for air passage, connected to the circuit via a pneumatic rotary joint and a plenum of the non-driving wheel, which is connected to the inner chamber of the tyre. Each driving or non-driving wheel has its plenum connected to the inner chamber via two parallel lines, for deflating and inflating, respectively, the tyre interposed in which are respective one-way valves.
