Abstract
Description
Die Erfindung betrifft eine Fahrzeugbremsanlagenkolbenpumpe gemäß dem Oberbegriff vom Patentanspruch 1.The The invention relates to a vehicle brake system piston pump according to the Preamble of claim 1.
Aus
der
Der Kolbendeckel greift von radial innen in die Kolbenrückstellfeder ein.Of the Piston cover engages from radially inward into the piston return spring one.
Gattungsgemäße Kolbenpumpen sind in elektronisch regelbaren Bremssystemen weit verbreitet. Diese weite Verbreitung, und eine hohe Fahrzeugausstattungsrate, erfordern eine fortgeschrittene Rationalisierung von Bauteilen, und auch eine Rationalisierung von Fertigungsschritten, damit die gewünschten Produktionszahlen je Zeiteinheit bei gegebenen Kosten eingehalten werden können. Weiterhin sollen Maßnahmen ergriffen werden, die bei gegebener Rationalisierung im Montagebereich weiterhin eine Verbesserung der Funktionssicherheit im Bereich der Rückstellfeder unterstützen.generic Piston pumps are far in electronically controlled braking systems common. This wide distribution, and a high vehicle equipment rate, require advanced rationalization of components, and also a rationalization of manufacturing steps, so that the desired production figures per time unit given Costs can be met. Furthermore, measures should be taken with a given rationalization in the assembly area continue to improve the reliability in the field of Support return spring.
Diese Aufgabe wird für eine gattungsgemäße Pumpe zusammen mit den kennzeichnenden Merkmalen vom Patentanspruch 1 gelöst. Die Erfindung besteht im Prinzip darin, dass die Rückstellfeder unterschiedliche Windungsdurchmesser aufweist. Dadurch wird der Montageprozess der Rückstellfeder verbessert. Knicktendenzen wird entgegen gewirkt. Nebenbei wird der Vorteil erzielt, dass der Kolbenrückstellprozess durch die veränderte Federsteifigkeit positiv beeinflusst ist. Eine weitere, wichtige Nebenwirkung der unterschiedlichen Windungsdurchmesser besteht darin, dass die Blocklänge – und dadurch die axiale Baulänge der Kolbenpumpe – reduziert ist, indem die Rückstellfeder gewissermaßen teleskopisch deformierbar ist. Wenn der Windungsdurchmesser jeweils endseitig reduziert ist, wird eine besonders vorteilhafte, tonnenförmige Federform ermöglicht, bei der der knickgefährdete Mittelabschnitt einen besonders großen Windungsdurchmesser mit geringer Knicktendenz aufweist.These Task is for a generic Pump together with the characterizing features of the claim 1 solved. The invention is in principle that the return spring different winding diameter having. As a result, the assembly process of the return spring improved. Kinking tendencies is counteracted. By the way, will achieved the advantage that the piston return process through the changed spring stiffness is positively influenced. Another important side effect of the different coil diameters is that the block length - and thereby the axial length of the piston pump - reduced is by the return spring in a sense telescopic is deformable. If the coil diameter each end is reduced, becomes a particularly advantageous, barrel-shaped Federform allows, in which the kink-prone Middle section a particularly large coil diameter having a low tendency to buckling.
In weiterer Ausgestaltung der Erfindung verfügt der Federtopf über einen Führungsabschnitt für die Rückstellfeder, so dass eine Stützwirkung gegeben ist, bevor es zu einem Knick kommen kann.In further embodiment of the invention, the spring cup over a guide section for the return spring, so that a supportive action is given before it becomes one Kink can come.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus Unteransprüchen zusammen mit nachstehender Beschreibung anhand der Zeichnung. In der Zeichnung zeigt jeweils im Schnitt sowie in größerem Maßstab:Further advantageous embodiments of the invention will become apparent from the dependent claims together with the description below with reference to the drawing.

Bei einer anderen Lösung sowie einem entsprechenden Verfahren zur Befestigung einer Rückstellfeder an einem Federtopf ist vorgesehen, dass ein Ende der Rückstellfeder mit Spiel in eine Aufnahme vom Federtopf eingesetzt ist. Dabei greift zumindest ein domförmiger Abschnitt vom Federtopf in das Ende der Rückstellfeder ein. Im Anschluß daran wird der Innendurchmesser vom Federtopf, zumindest im Bereich vom domförmigen Abschnitt durch Prägen, Verstemmen oder ähnlichem derart plastisch nach radial außen aufgeweitet, dass eine Klemmwirkung zwischen Rückstellfeder und Federtopf wirksam ist.In another solution and a corresponding method for fixing a return spring to a spring cup is provided that one end of the return spring is inserted with play in a receptacle of the spring cup. At least one dome-shaped section of the spring cup engages in the end of the return spring. Following this, the inner diameter of the spring cup, at least in the area of the dome-shaped section by embossing, caulking or the like so widened radially outward plastically that a clamping action between the return spring and spring cup is effective.
