摘要： A braking system for a vehicle having two pairs of wheels, has two master cylinders operating as pumps, wherein each master cylinder is operated by its own brake pedal and controls the braking on one rear wheel, as well as on the front wheels through a valve for the disconnection of the front vehicle braking. Each master cylinder is of the tandem type including two sections, the first section controlling the braking of the front wheels through the valve, whereas the second section controls the braking of that rear wheel, being a part of the pair of rear wheels, which is associated with the master cylinder. The first sections of both master cylinders are supplied by a first oil reservoir and the second sections of both master cylinders are supplied by a second oil reservoir at least partially independent from the first oil reservoir.

摘要： The invention concerns a master cylinder assembly (10, 110) for balancing the braking of a couple of wheels (LBW, RBW) of a vehicle. Each master cylinder (12) has a hollow body (14), a piston (15) and a chamber (16) suitable for containing a fluid having a primary control pressure depending on a driving force applied on the piston (15) and intended to be transmitted to a utilising device (LBB, RBB). The assembly further includes a balancing duct (58) into which the chambers (16) come out, and a plurality of normally closed balancing valves (60). Each balancing valve (60) is located between the balancing duct (58) and a respective chamber (16) and has a shutter (62) which is mechanically unconstrained to the primary piston (15) defining the primary chamber (16) to which said primary balancing valve (60) is associated, and which is operable for opening in a manner fluid-controlled by the primary control pressure taken by the fluid contained in the primary chamber (16) to which said balancing valve (60) is associated.

摘要： A valve intended to disconnect, in specific circumstances, the braking of the front wheels, and/or of a trailer whose braking system is connected through a trailer braking valve, for the braking system of a farm tractor or similar vehicle which includes two master cylinders, operated by two separate braking pedals, directly controlling the braking of the rear wheels, and controlling the braking of the front wheels and/or the braking device of the trailer through the disconnection valve. The disconnection valve includes a body, first and second inlet connections connected to the two master cylinders, and a delivery connection connected to a braking circuit of the front wheels and/or to the trailer brake valve. The valve body has a bore wherein is installed one movable piston subjected to the action of pressure applied to the first inlet connection.
