Description
Stand der TechnikState of the art
Die Erfindung betrifft ein Hydroaggregat für eine elektronisch schlupfregelbare Fahrzeugbremsanlage mit einem umformtechnisch an einem Hydraulikblock dieses Hydroaggregats verankerten Antriebsmotor entsprechend den gattungsbildenden Merkmalen des Anspruchs 1 sowie ein Verfahren zur umformtechnischen Verankerung eines Antriebsmotors an einem Hydraulikblock eines Hydroaggregats einer elektronisch schlupfregelbaren Fahrzeugbremsanlage entsprechend den gattungsbildenden Merkmalen des Anspruchs 9.The The invention relates to a hydraulic unit for an electronic slip-controllable vehicle brake system with a forming technology a hydraulic block of this hydraulic unit anchored drive motor accordingly the generic features of claim 1 and a method for forming technology anchoring a drive motor to a Hydraulic block of a hydraulic unit of an electronic slip-controllable Vehicle brake system according to the generic features of Claim 9.
Hydroaggregate sind mit wenigstens einem von einem Antriebsmotor angetriebenen Pumpenelement ausgestattet. Sie dienen bei schlupfgeregelten Fahrzeugbremsanlagen zur Modulation des Bremsdrucks an den Radbremsen in Abhängigkeit der vorherrschenden Schlupfverhältnisse an den zugeordneten Rädern. Eine Modulation des Bremsdrucks erfolgt während eines Bremsvorgangs um ein Blockieren eines gebremsten Rades zu verhindern oder um einen eventuell auftretenden Radschlupf während eines Beschleunigungsvorgangs oder während eines instabilen Fahrzustands des Fahrzeugs unabhängig vom Bremswunsch des Fahrers zu beseitigen.Power units are at least one driven by a drive motor Equipped pump element. They serve in slip-controlled vehicle brake systems for modulation of the brake pressure at the wheel brakes in dependence the prevailing slip conditions on the assigned Wheels. A modulation of the brake pressure takes place during braking to lock a braked wheel prevent or avoid any wheel slip during an acceleration process or during an unstable Driving condition of the vehicle regardless of the braking request of To eliminate the driver.

Die umformtechnische Befestigung des Antriebsmotors am Hydraulikblock ist druckmitteldicht ausgeführt, um einen Austritt von Druckmittel aus dem Hydraulikblock zur Umgebung hin zu vermeiden. In Dauerversuchen hat sich jedoch gezeigt, dass die aus der o. g. Druckschrift bekannte Befestigungsgeometrie die erforderlichen Dichtheitserfordernisse nicht unter allen Betriebs- und Umgebungsbedingungen über die Lebensdauer des Hydroaggregats erfüllt.The Forming technical attachment of the drive motor to the hydraulic block is pressure-tight to prevent leakage Pressure medium from the hydraulic block to the environment to avoid. In endurance tests, however, it has been shown that the o. G. Publication known attachment geometry the required tightness requirements not under all operating and environmental conditions fulfills the service life of the hydraulic unit.
Vorteile der ErfindungAdvantages of the invention
Demgegenüber hat die Erfindung mit den Merkmalen des Anspruchs 1 den Vorteil, dass durch eine modifizierte Befestigungsgeometrie die Dichtheit zwischen Antriebsmotor und Hydraulikblock verbessert werden konnte, ohne die Teilekosten zu verteuern.In contrast, the invention with the features of claim 1 has the advantage that by a modified attachment geometry, the tightness between drive motor and hydraulic block could be improved, without increasing the cost of parts.
Erfindungsgemäß wird vorgeschlagen, die ohnehin vorhandene und den Antriebsmotor aufnehmende Ansenkung mit einer zusätzlichen verformbaren Prägefase zu versehen und ferner eine Ausgleichsnut am Boden dieser Ansenkung vorgesehen, in die Material der Prägefase hineinverdrängbar ist. Die Unteransprüche begehren Schutz für spezielle Ausgestaltungen der Befestigungsgeometrie mit weiter verbesserten Dichtheitseigenschaften. Mit Anspruch 9 wird ein Verfahren beansprucht anhand dem eine erfindungsgemäße Verankerung eines Antriebsmotors an einem Hydraulikblock eines Hydroaggregats herstellbar ist.According to the invention proposed, the already existing and the drive motor receiving Countersink with an additional deformable embossing chamfer to provide and also a compensation groove at the bottom of this countersink provided, hineinverdrängbar in the material of the embossing chamfer is. The dependent claims seek protection for special designs the mounting geometry with further improved sealing properties. With claim 9, a method is claimed on the basis of an inventive Anchoring a drive motor to a hydraulic block of a hydraulic unit can be produced.
