  • Publication number: 20220379859
    Abstract: A vehicle braking system includes a master cylinder. In a delivery line of the master cylinder there is a pressure transfer device, which generates a pressure in a hydraulic actuating line of a respective brake device following a fluid pressure communicated to a first inlet of the pressure transfer device from the delivery line and/or following a fluid pressure supplied to a second inlet of the pressure transfer device from an electrically-operated fluid pressure source. An electronic controller controls an enabling/disabling solenoid valve, and the electrically-operated fluid pressure source to create different operating modes of the system. The system does not include any vacuum-operated servo-assisting devices. The master cylinder is associated with a hydraulic device for adjusting the feeling on the brake pedal, in which a fluid pressure is generated that opposes the brake pedal actuation. The electronic controller controls the pressure in the device for adjustment of the feeling on the pedal.

  • Patent number: 11390257
    Abstract: A vehicle braking system includes an assistance device having a vacuum pump driven by an engine for communicating vacuum to a chamber of the assistance device. A control valve is interposed along a fluid line between the pump and the chamber. The control valve is in its first operative condition, where the inlet side of the vacuum pump communicates with the chamber, when pressure within the chamber is above a predetermined value; and is in its second operative condition, where the inlet side of the vacuum pump communicates with the atmosphere, when pressure within the chamber is below a predetermined value. In this second condition the pump intakes air from and feeds air into the atmosphere, thereby reducing the energy consumption by the engine required for driving the pump during stages where, within the chamber, there is a vacuum sufficient for the regular operation of the braking system.

  • Patent number: 10926589
    Abstract: 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.

  • Patent number: 10828941
    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.

  • Publication number: 20200290597
    Abstract: A system and method for controlling a balance of a moving motor vehicle whose pitching motion when overcoming an unevenness of the road is corrected by means of an acceleration and/or a deceleration of the vehicle by a value correlated to a level of unevenness of the road. The level of unevenness is detected by monitoring the road ahead of the moving vehicle and the pitching motion is predictively corrected based on such monitoring.

  • Patent number: 8342280
    Abstract: An agricultural vehicle having a hydraulic system, a cab for the vehicle operator includes a self-levelling cab suspension system having a plurality of suspension units each having a spring, a damper and an accumulator. The accumulator comprises a hydraulic working chamber which is separated by a movable wall from a gas filled chamber serving as a spring. The working chamber is also connected to a working chamber of the damper in a closed hydraulic circuit. In the invention, there is no need for a dedicated oil pump since a hydraulic actuator powered by the vehicle hydraulic system is provided for causing hydraulic fluid to flow in the closed hydraulic circuit between the working chamber of the accumulator and the damper, to vary the height of the cab without fluid from the vehicle hydraulic system entering or leaving the closed hydraulic circuit of the damper and accumulator.
