Abstract
Description
Die Erfindung betrifft einen Hauptzylinder, insbesondere für ein geregeltes Bremssystem, mit wenigstens einem, in einem Gehäuse verschiebbaren Kolben, der mittels eines, in einer Ringnut des Gehäuses angeordneten Dichtelementes gegenüber einem Druckraum abgedichtet ist, welcher durch im Kolben ausgebildete Querbohrungen mit einem drucklosen Nachlaufraum verbindbar ist.The The invention relates to a master cylinder, in particular for a controlled Brake system, with at least one displaceable in a housing piston, the means of a, arranged in an annular groove of the housing sealing element opposite one Pressure chamber is sealed, which is formed by in the piston Transverse bores with a non-pressurized follow-up space is connectable.

der
Der Erfindung liegt daher die Aufgabe zugrunde, einen dahingehend verbesserten Hauptzylinder bereitzustellen.Of the The invention is therefore based on the object to improve to an extent To provide master cylinder.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass auf einer Innenseite des Kolbens Ausnehmungen vorgesehen sind, in welche die Querbohrungen münden. Hierdurch entfällt einerseits eine aufwendige Bearbeitung der Außenseite des Kolbens, andererseits wird eine Lochlänge der Querbohrungen, d.h. die axiale Ausdehnung der Querbohrungen, reduziert, wodurch eine Verringerung des Drosselwiderstandes erreicht wird. Zusätzlich kann der Leerweg des Hauptzylinders klein gehalten werden.According to the invention Task solved by that recesses are provided on an inner side of the piston, in which the transverse bores open. This is eliminated on the one hand a complex processing of the outside of the piston, on the other becomes a hole length the transverse bores, i. the axial extent of the transverse bores, reduces, thereby achieving a reduction of the throttle resistance becomes. additionally the free travel of the master cylinder can be kept small.
Um die Herstellbarkeit des Kolbens zu vereinfachen, weist der Kolben an einer Seite eine im wesentlichen topfförmige Wandung mit einem ersten Innendurchmesser und einem zweiten Innendurchmesser, wobei der zweite Innendurchmesser größer ist als der erste Innendurchmesser, und wobei die Querbohrungen in einem Bereich zwischen dem ersten und dem zweiten Innendurchmesser angeordnet sind.Around To simplify the manufacturability of the piston, the piston has on one side a substantially cup-shaped wall with a first inner diameter and a second inner diameter, wherein the second inner diameter is larger as the first inner diameter, and wherein the transverse bores in one Region between the first and the second inner diameter are arranged.
In vorteilhafter Weiterbildung der Erfindung sind die Ausnehmungen als eine umlaufende, radiale Innennut ausgebildet, welche mit geringem Aufwand herstellbar ist. Eine Nachbearbeitung der Innennut ist nicht erforderlich. Gleichzeitig kann der Kolben axiale Kräfte, die beim Anschlagen des Kolbens an das Gehäuse bzw. an den zweiten Kolben auf den Kolben wirken, ohne eine Deformierung aufnehmen, da die Wandstärke des Kolbens am Ende nicht geschwächt wird.In Advantageous development of the invention are the recesses formed as a circumferential, radial inner groove, which with low Effort can be produced. A post-processing of the inner groove is not required. At the same time, the piston axial forces, the when striking the piston to the housing or to the second piston act on the piston, without a deformation record, since the wall thickness of Piston is not weakened at the end.
Eine andere vorteilhafte Ausführungsform der Erfindung wird dadurch erreicht, dass die Ausnehmungen als Zahnzwischenräume eines Zahnprofils auf der Innenseite des Kolbens ausgebildet sind, wobei sich die Ausnehmungen vorteilhafterweise in axialer Richtung bis zum Ende des Kolbens erstrecken. Der Kolben mit den Ausnehmungen kann somit im Tiefziehverfahren hergestellt werden, ohne dass für die Herstellung der Ausnehmungen ein zusätzlicher Bearbeitungsaufwand notwendig ist. Gleichzeitig wird die Wandstärke des Kolbens am Ende nur partiell reduziert, wodurch der Kolben die auftretenden axialen Kräfte ohne eine Deformierung aufnehmen kann.A Another advantageous embodiment of the Invention is achieved in that the recesses as interdental spaces of a Tooth profiles are formed on the inside of the piston, wherein the recesses advantageously in the axial direction until extend to the end of the piston. The piston with the recesses can thus be prepared by deep-drawing, without for the production the recesses an additional Processing effort is necessary. At the same time the wall thickness of the Piston at the end only partially reduced, causing the piston to occur axial forces can absorb without deformation.
Als ein günstiges Verhältnis Lochlänge zu Lochdurchmesser der Querbohrungen hat sich bei Versuchen ein Verhältnis mit dem Wert von ca. 1 herausgestellt.When a cheap one relationship hole length to hole diameter of the cross holes has become a trial relationship with the value of approx.
