Abstract
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.
