DISSYMMETRIC BRAKING SYSTEM FOR VEHICLE

The object of the present invention is a dissymmetric braking system (1) for vehicle (2), in which said vehicle comprises at least one first vehicle axle (3 or 15) supported by at least one right axle wheel (4 or 36) and at least one left axle wheel (5 or 37) of the vehicle; in which said braking system (1) comprises: - at least one right wheel braking device (6 or 34); - at least one left wheel braking device (7 or 35); - at least one device to apply a braking action by the driver (8); - at least one actuating device (9) to transform the braking action into a braking pressure command or first pressure or input pressure (PI); - at least one right wheel connection (10 or 38) between said at least one actuating device (9) and said first axle right wheel braking device (6 or 34); at least one left wheel connection (11 or 39) between said at least one actuating device (9) and said first axle left wheel braking device (7 or 35); at least one pressure reducing device (12) is provided in one of said connections (10, 11 or 38, 39); said pressure reducing device (12) comprises at least one transfer device (13) which receives said first pressure (PI); and in which said at least one transfer device (13) transforms said first pressure (PI) into a reduced braking pressure or second pressure or output pressure (P2), whereby avoiding, during the braking action, a fluidic connection between a fluid which has said first pressure (PI) and a fluid which has said second pressure (P2); so as to determine, during the braking action, a relationship between said first pressure (PI) and said second pressure (P2) with linear, or proportional, trend without variation of linearity or proportionality throughout the operating field of the pressure reducing device (12); and so that the braking action of one of said at least one right wheel braking device (6 or 34) and at least one left wheel braking device (7 or 35) is lower than the other.
