Electrohydraulic pressure control device with improved electromagnetic compatibility

摘要

The invention relates to an electrohydraulic pressure control device (1) for vehicle brake systems comprising at least one electronic control unit (4), at least one hydraulic unit (3) and at least one electric motor (2) at least partially enclosed by a housing for driving a hydraulic pump, wherein the electronic control unit (4) the electric motor (2) by means of at least one motor contact plug (6) controls, which is guided by at least one through hole of the hydraulic unit and by means of at least one electrical conductor at least one motor contact (7) and / or motor supply (11) with a by the electronic Control unit (4) comprising the printed circuit board (5) electrically conductively connects and at least one capacitive coupling of the electrical conductor of the motor contact plug (6) and / or at least one motor contact (7) and / or the motor supply line (11) by means of at least one interference suppression capacitor (9) the Electric motor (2) and / or at least one housing of the electric motor (2) and / or the hydraulic unit (3) is provided in such a way that the electric motor (2) and / or the housing of the electric motor (2) and the hydraulic unit (3 ) are used for the realization of an electromagnetic shielding of the electro-hydraulic pressure control device (1).
