| description | PCT No. PCT/EP93/00005 Sec. 371 Date Oct. 5, 1994 Sec. 102(e) Date Oct. 5, 1994 PCT Filed Jan. 4, 1993 PCT Pub. No. WO93/12960 PCT Pub. Date Jul. 8, 1993A slip control system determines friction/slip characteristics of tires of a road vehicle equipped both with an antilock system to permit an individual brake pressure control on individual vehicle wheels. The front wheel brakes are connected to a primary output pressure space of the tandem master cylinder, and the rear wheel brakes are connected to a secondary output pressure space of the tandem master cylinder. A first bore stage of a housing of the tandem master cylinder forms a housing-defined boundary of the secondary output pressure space. An inner piston flange movably seals off a pressureless downstream chamber in relation to an inner portion of the first bore stage. An intermediate wall of the housing delimits the bore stage relative to a central bore stage which extends from a third bore stage receiving a primary piston. An actuating piston is displaceably guided in the central bore stage in a pressure tight manner and forms an axially movable, inner boundary of the primary output pressure space relative to a pressureless downstream chamber in the central bore stage which is bounded by the intermediate wall. An annular space is bounded in an axially movable manner by an inner piston flange of a secondary piston and by the intermediate wall and is connected to the pressure output of the controllable pressure source. |
