Description
Die Erfindung betrifft eine elektronisch geregelte Bremsanlage mit einer Betätigungseinheit, mit Radbremsen und mit einer Regeleinheit zwischen der Betätigungseinheit und den Radbremsen, wobei die Regeleinheit zumindest eine Pumpe mit einer Saugseite und mit einer Druckseite und ein, zur Schlupfregelung dienendes, elektrisches Umschaltventil zwischen der Saugseite der Pumpe und der Betätigungseinheit aufweist, wobei zwischen dem Umschaltventil und der Saugseite der Pumpe ein Pulsationsdämpfer angeordnet ist.The The invention relates to an electronically controlled brake system with a Operating unit, with wheel brakes and with a control unit between the operating unit and the wheel brakes, wherein the control unit at least one pump with a suction side and with a pressure side and a, for slip control Serving, electrical switching valve between the suction side of the Pump and the actuator having, between the switching valve and the suction side of the Pump a pulsation damper is arranged.

Der
Die bekannten Bremsanlagen erfüllen ihren Zweck, sind aber konstruktiv vergleichsweise aufwendig, da der Pulsationsdämpfer im Hydro- bzw. Niederdruckspeicher integriert oder als Baugruppe außerhalb des Hydraulikblocks oder aber direkt in der Saugleitung der Pumpe angeordnet ist. Dies erfordert an den genannten Stellen einen relativ großen Platzbedarf beziehungsweise erhöhten Montageaufwand.The meet known braking systems their purpose, but are structurally relatively expensive, since the pulsation damper integrated in the hydraulic or low-pressure accumulator or as an assembly outside of the hydraulic block or directly in the suction line of the pump is arranged. This requires a relative at the places mentioned large space requirement or increased Installation effort.
Der Erfindung liegt daher die Aufgabe zugrunde, die erforderliche Dämpfung der Pulsationen mit möglichst geringem konstruktiven Aufwand und fertigungstechnisch einfachen Mitteln zu realisieren sowie den insgesamt für die Regeleinheit einer elektronischen Bremsanlage benötigten Bauraum zu minimieren.Of the Invention is therefore based on the object, the required attenuation of Pulsations with as possible low design effort and production technology simple To realize funds and the total for the control unit of an electronic Brake system needed To minimize installation space.
Zur Lösung dieser Aufgabe wird eine elektronisch geregelte Bremsanlage der eingangs genannten Art vorgeschlagen, bei der der Pulsationsdämpfer in einer Stufenbohrung eines Gehäuses angeordnet ist, in der ebenfalls das elektrische Umschaltventil vorgesehen ist. Auf diese Weise wird der dort vorhandene Bauraum optimal genutzt. Der insgesamt für die Regeleinheit benötigte Baumraum wird erfindungsgemäß minimiert.to solution This object is an electronically controlled brake system mentioned in the introduction, in which the pulsation damper in a stepped bore of a housing is arranged, in which also provided the electrical switching valve is. In this way, the space available there is used optimally. The total for needed the control unit Tree space is minimized according to the invention.
Der Pulsationsdämpfer umfaßt insbesondere eine elastische Membran und einen Sicherungsring zur Festlegung der Membran in einem Gehäuse oder dergleichen. Vorzugsweise ist der Dämpfer in einer Stufenbohrung des Gehäuses der Regeleinheit angeordnet, in der sich auch das elektrische Umschaltventil befindet. Mit Vorteil kann die Stufenbohrung dann endseitig eine Verlängerung aufweisen, die von der darin befestigten Membran in einen Raum für die Bremsflüssigkeit und einen Gasspeicherraum unterteilt ist.Of the pulsation dampers comprises in particular an elastic membrane and a retaining ring for Fixing the membrane in a housing or the like. Preferably is the damper in a stepped bore of the housing arranged the control unit, in which also the electrical switching valve located. Advantageously, the stepped bore then an end renewal from the membrane mounted therein into a space for the brake fluid and a gas storage room is divided.
Durch die Integration des Pulsationsdämpfers in das Umschaltventil bzw. durch dessen Unterbringung in die für das Umschaltventil im Gehäuse ohnehin vorgesehene Stufenbohrung erreicht man, daß der Pulsationsdämpfer aus lediglich zwei Bauteilen aufgebaut werden kann, weil die Stufenbohrung die Funktion eines Gehäuses für den Pulsationsdämpfer übernimmt.By the integration of the pulsation damper in the switching valve or by its placement in the for the switching valve in the case anyway provided stepped bore to reach that the pulsation damper off only two components can be built, because the stepped bore the Function of a housing for the Pulsation damper takes over.
Neben der konstruktiven Einfachheit und der günstigen Fertigung des Umschaltventils mit integriertem Pulsationsdämpfer wird der funktionelle Effekt kurzer Leitungswege als besonders vorteilhaft angesehen.Next the constructive simplicity and the favorable production of the switching valve with integrated pulsation damper the functional effect of short conduction paths is considered particularly advantageous.
