A TWO MASTER CYLINDER BRAKING SYSTEM FOR A VEHICLE HAVING A SAFETY FUNCTION

摘要

A braking system for a vehicle having two pairs of wheels (RAS, RAD ; RPS ,RPD) , comprising two master cylinders (CTS/CTD) operating as pumps, wherein each master cylinder is (CTS, CTD) operated by its own brake pedal (PS, PD) and controls the braking on one rear wheel (RPS, RPD) , as well as on the front wheels (RAS, RAD) through a valve (VD) for the disconnection of the front vehicle braking, and wherein each master cylinder is of the tandem type comprising two sections (CTS1, CTS2 ; CTD1, CTD2) , the first section (CTS1, CTD1) controlling the braking of the front wheels (RAS, RAD) through the valve (VD) for disconnection of the front vehicle braking, whereas the second section (CTS2,CTD2) of the master cylinder controls the braking of that rear wheel (RPS or RPD) , being a part of the pair of rear wheels, which is associated with said master cylinder, the first sections (CTS1, CTD1) of both master cylinders being supplied by a first oil reservoir (S1) and the second sections (CTS2,CTD2) of both master cylinders being supplied by a second oil reservoir (S2) at least partially independent from the first oil reservoir (S1) .
