Description
Die Erfindung betrifft eine miniaturisierte Fahrzeugbremsanlagenkolbenpumpe zur Förderung von Druckmittel in einem geregelten Bremssystem.The The invention relates to a miniaturized vehicle brake system piston pump for the promotion of pressure medium in a regulated braking system.
Für die Ventilierung in Fahrzeugbremsanlagenkolbenpumpen werden bevorzugt stark miniaturisierte, und gekapselte Ventilpatronen verwendet, die als selbständig handhabbare Baueinheiten prinzipiell von spezialisierten Zulieferern bezogen werden können. Die Ventilpatronen sind so ausgebildet, dass diese äußerst multifunktional, also auch für die unterschiedlichsten Anwendungen jenseits vom Automobilsektor, geeignet sind, und ferner für unterschiedlichste Medien verwendbar sind. Jede dieser Ventilpatronen verfügt über ein weitgehend zylindrisches Gehäuse zur Einpress-Anordnung in einer zylindrischen Kanalbohrung eines Aufnahmekörpers für die Pumpe. Ein Ventilsitz ist an einem gesondert eingefügten Bauelement angeordnet. Der Ventilsitz wird von einem meist kugelförmigen Ventilkörper beaufschlagt, welcher permanent durch eine Schließfeder elastisch in Schließstellung gehalten wird. Für eine definierte Abstützung der Schließfeder ist am Gehäuse ein geeignetes Abstützelement vorgesehen, welches die Schließfeder zumindest teilweise zylindrisch umgibt, damit diese gegen Ausknicken geschützt ist. Je nach Ausführung als Druck- oder als Saugventil, wird die Ventilpatrone gerichtet in einem Saug- oder Druckpfad der Fahrzeugbremsanlagenkolbenpumpe eingesetzt. Die angebotenen Rückschlagventil-Patronen erfüllen Ihre Aufgabe grundsätzlich zufriedenstellend, und sie werden insbesondere aus Kostengründen in der Fahrzeughydraulik vielfach angewendet.For the ventilation in vehicle brake piston pumps are preferred heavily miniaturized, and used encapsulated valve cartridges, in principle, the units that can be handled independently can be obtained from specialized suppliers. The Valve cartridges are designed to be extremely durable multifunctional, including for the most diverse Applications beyond the automotive sector, are suitable, and further can be used for a wide variety of media. Each of these Valve cartridges has a largely cylindrical housing for press-fitting arrangement in a cylindrical channel bore of a Receiving body for the pump. A valve seat is arranged on a separately inserted component. The valve seat is characterized by a mostly spherical valve body acted upon, which is permanently elastic by a closing spring is held in the closed position. For a defined Support of the closing spring is on the housing a suitable support element is provided, which the closing spring at least partially surrounds cylindrical, so that it against buckling is protected. Depending on the design as printing or as a suction valve, the valve cartridge is directed in a suction or pressure path of the vehicle brake system piston pump used. The meet the non-return valve cartridges Your task basically satisfactory, and they will especially for cost reasons in the vehicle hydraulics used many times.
Obwohl die beschriebenen Ventilpatronen in Alleinstellung hochminiaturisiert ausgebildet sind, besteht dennoch das besondere Bedürfnis, den gesamten Bauraumbedarf eines Fahrzeugkolbenpumpensystems, einschließlich des Auslassventils, zu verringern. Weiterhin ist eine radial wirksame Einpress-Anordnung nicht völlig ohne Risiko, weil prinzipiell jegliche radiale Deformation vom Gehäuse zu einer unerwünschten Verformung am Ventilsitz, an Führungsflächen oder an ähnlichen Funktionsträgern führen kann. Demzufolge sind montagebedingte Undichtigkeiten oder unerwünschtes Klemmen im Bereich vom Ventilkörper denkbar. Es ist eine Aufgabe der vorliegenden Erfindung, die genannten Nachteile zu vermeiden.Even though the described valve cartridges highly miniaturized in isolation are trained, there is nevertheless the special need the entire space requirement of a vehicle piston pump system, including of the exhaust valve. Furthermore, a radially effective Press-fitting arrangement is not completely without risk, because in principle any radial deformation from the housing to an undesirable Deformation on the valve seat, on guide surfaces or can lead to similar function carriers. As a result, installation-related leaks or unwanted Clamps in the area of the valve body conceivable. It is one Object of the present invention to avoid the disadvantages mentioned.

Die Aufgabe wird erfindungsgemäß gelöst, indem das Gehäuse für das Auslassventil ferner als Bohrungsverschluss für den Aufnahmekörper ausgebildet ist, und dass eine weitgehend koaxial zu einem Pumpenkolben ausgebildete, abgestufte, Durchgangsbohrung vorgesehen ist, deren Bohrungswandung zur Führung für die Bauteile von dem Auslassventil, sowie zur Führung für die Rückstellfeder von dem Pumpenkolben, vorgesehen ist. Erfindungsgemäß wird von einer isolierten Ventilkapsel Abstand genommen, indem mehrere Bauteile mit den entsprechenden Funktionalitäten in einer Baueinheit zusammen gefasst sind.The The object is achieved according to the invention by the housing for the outlet valve further as a bore closure is designed for the receiving body, and that a largely coaxial with a pump piston formed, graduated, Through hole is provided, the bore wall for guiding for the components of the exhaust valve, as well as for guidance for the return spring of the pump piston, provided is. According to the invention is isolated from Valve capsule distance by placing several components with the corresponding Functionalities are combined in one unit.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass der Bohrungsverschluss einen sphärisch-konvex gewölbten Boden aufweist, der als Widerlager für die Schließfeder dient. Durch diese Maßnahme wird eine präzise Zentrierung von der Schließfeder bewirkt. In besonders kostengünstiger Ausgestaltung der Erfindung ist der Boden mit einer Kugel versehen, die in die Durchgangsbohrung eingepresst ist, und als Widerlager für die Schließfeder dient. Die Kugel kann in äußerst präziser Ausfertigung als kostengünstiges Massenteil (Wälzkugel) beschafft werden, und ermöglicht sowohl den Verschluss der Durchgangsbohrung, als auch die Zentrierung der Schließfeder auf besonders kostengünstigem Wege.In Another embodiment of the invention is provided that the bore closure has a spherical-convex curved bottom, which serves as an abutment for the closing spring. By this measure, a precise centering caused by the closing spring. In a particularly cost-effective design the invention, the bottom is provided with a ball which in the Through hole is pressed, and as an abutment for the closing spring is used. The ball can be extremely precise copy as a cost-effective mass part (Rolling ball), and allows both the closure of the through hole, as well as the centering of the Closing spring in a particularly cost-effective way.
In weiterhin vorteilhafter Ausbildung der Erfindung verfügt die Stufenbohrung vom Gehäuse über eine Stufe, welche einen angeformten Ventilsitz für den Schließkörper aufweist.In further advantageous embodiment of the invention has the stepped bore from the housing over a step, which a molded valve seat for the closing body having.
Ausgehend von der Stufe mit dem Ventilsitz ist die Stufenbohrung in axialer Richtung hin zum Pumpenkolben, als auch in die diametral entgegen gesetzte Richtung jeweils so ausgebildet, dass sich deren Durchmesser mit wachsendem Axialabstand von der Stufe sukzessiv erweitert. Durch diese Maßnahme werden die bestehenden Montageproblematiken zum Einfügen der Bauteile vom Auslassventil, wie auch die abschließende Verkugelung gelöst.Starting from the stage with the valve seat, the stepped bore in the axial direction to the pump piston, as well as in the diametrically opposite direction are each designed so that the diameter of which gradually increases with increasing axial distance from the stage. By this measure, the existing mounting problems ken to insert the components of the exhaust valve, as well as the final Verkugelung solved.
Zur Vermeidung von hydraulischer Undichtigkeiten infolge unterschiedlicher Wäremedehnungskoeffizienten wird vorteilhafter Weise vorgeschlagen, dass sowohl der Aufnahmekörper, als auch das daran angrenzende Gehäuse jeweils aus Aluminiumwerkstoff ausgebildet sind. Unter diesen Voraussetzungen wird weiterhin vorteilhaftweise vorgesehen, dass zumindest eine Außenwandung vom Gehäuse spanlos durch Kaltumformung hergestellt ist, während die gestufte Druchgangsbohrung spanend ausgeführt ist.to Avoidance of hydraulic leaks due to different Thermal expansion coefficient is advantageously proposed that both the receiving body, as well as the adjacent thereto Housing are each formed of aluminum material. Under these conditions, it is furthermore advantageously provided that that at least one outer wall of the housing without cutting made by cold forming while the stepped Druchgangsbohrung is carried out machining.
