Abstract:
Device for brake pressure control in hydraulic brake systems of vehicles, comprising:a housing accommodating an axially displaceable abutment for a simulator spring of an actuating device that is mechanically coupled to a brake pedal, the said abutment in its initial position bearing against a stop provided in the housing, a master brake cylinder that has at least one brake piston, a pressure supply device with a motor-driven pump, pressure reservoir and control valve, an unpressurized supply reservoir for the hydraulic pressure fluid including all necessary connecting lines, and an electric or electronic control device, wherein the simulator spring is arranged between the abutment and the actuating device, at least one measuring data emitter for the relative movement between the actuating device and the abutment or for the pedal force introduced into the simulator spring, one measuring data emitter for the position of a brake piston, and one measuring data emitter for the pressure in the brake circuit or between the control valve and the housing, wherein the hydraulic pressure fluid which flows from the pressure supply device via the control valve is exclusively fed into a chamber of the housing where it urges the abutment against the stop, and applies pressure to at least one brake piston.
