Abstract:
A modular braking device for a hydraulic motor vehicle brake system, which is optimized for remote actuation, including a hydraulic booster stage with a booster housing, a main brake cylinder mounted thereon, a booster piston which is displaceable therein and delimits a pressure chamber which is supplied directly with pressure medium by a motor pump unit.

Claim (Index 1):
A brake device ( 1 ) for a hydraulic motor vehicle brake system, comprising:\n a hydraulic booster stage, having a booster housing, having a booster piston which is mounted displaceably in the booster housing and which, here, separates a pressure chamber from a return chamber, wherein the pressure chamber and the return chamber are filled with a hydraulic pressure medium, a master brake cylinder with a linearly displaceable pressure piston which generates brake pressure in a pressure chamber which is delimited by said pressure piston and which is filled with the pressure medium, wherein the booster piston acts on the pressure piston with a boosting force which results from the pressure in the pressure chamber, an electrically driven motor-pump unit which feeds the pressure medium into the pressure chamber, a pressure medium reservoir for the supply of the pressure medium to the motor-pump unit ( 10 ), a return connection which connects the return chamber to the pressure medium reservoir, a piston rod which is actuatable by a brake pedal and which is guided in displaceable fashion by the booster piston and which has a hydraulic passage which, in a manner dependent on an axial relative position between the piston rod and booster piston, permits a hydraulic connection between the return chamber and the pressure chamber, a sensor device for a direct or indirect detection of position and/or movement of the piston rod, a first control edge which, in the open state, permits the connection between the hydraulic passage and, in the closed state, shuts off said connection, an elastic reaction disk, which is arranged between the piston rod and the pressure piston and which, when the piston rod is actuated by the brake pedal, is compressible with generation of a reaction force.
