Die Erfindung betrifft eine Kühlmittelpumpe für den Einsatz im KFZ-Bereich zur Förderung eines Kühlmittel-Volumenstroms mit einem Gehäuse, in dem eine Pumpenwelle mit einem drehfest darauf angeordneten Laufrad drehbar gelagert ist, wobei eine Regeleinrichtung zur Regelung des Volumenstroms vorgesehen ist, die ein in einen Ausströmbereich des Laufrades verschiebbares Schieberelement aufweist, das über eine Hydrauliksteuereinrichtung antreibbar ist, wobei die Hydrauliksteuereinrichtung eine Radialkolbenpumpe, eine Stelleinrichtung, eine Steuerkanalanordnung und mindestens eine Kolbenvorrichtung aufweist, die fluidisch derart miteinander verbindbar sind, dass das Schieberelement durch die Kolbenvorrichtung betätigbar ist, wobei die Stelleinrichtung eine mit der Steuerkanalanordnung in Wirkverbindung stehende Ventilanordnung aufweist, bestehend aus einem Elektromagnetventil und mindestens einem Rückschlagventil.The invention relates to a coolant pump for use in the motor vehicle area for promoting a coolant volume flow with a housing in which a pump shaft is rotatably mounted with a rotatably mounted impeller thereon, wherein a control device is provided for controlling the volume flow, the one in a Outflow of the impeller sliding slide element has, which is drivable via a hydraulic control device, wherein the hydraulic control device comprises a radial piston pump, an actuating device, a control channel arrangement and at least one piston device, which are fluidically interconnected such that the slide element is actuated by the piston device, wherein the actuating device a standing with the control channel arrangement in operative connection valve assembly comprising a solenoid valve and at least one check valve.
Regelbare Kühlmittelpumpen sind aus dem Stand der Technik hinlänglich bekannt. Die Regelung dient insbesondere dazu, die Kühlleistung der Kühlmittelpumpe an die Leistung und die jeweilige Betriebsphase des Motors des Kraftfahrzeuges optimal anzupassen, um einen effizienten und emissionsarmen Betrieb bei minimiertem Kraftstoffverbrauch zu gewährleisten. So beschreibt insbesondere die
Aufgabe der Erfindung ist es daher, eine Kühlmittelpumpe bereitzustellen, die auf einfache, kostengünstige und bauraumoptimierte Weise eine Regelung ermöglicht, die die obengenannten Nachteile vermeidet.The object of the invention is therefore to provide a coolant pump that allows a simple, cost-effective and space-optimized manner a scheme that avoids the disadvantages mentioned above.
Diese Aufgabe wird dadurch gelöst, eine Arretiervorrichtung für die Radialkolbenpumpe vorgesehen ist, mit der die Radialkolbenpumpe von einem Stand-by-Modus in einen Betriebsmodus und vice versa schaltbar ist. Hierdurch ist es möglich, eine wesentlich kompaktere und damit bauraumgünstigere Kühlmittelpumpe bereitzustellen, wobei die Radialkolbenpumpe lediglich bei Bedarf zugeschaltet wird, wodurch Verschleiß und Reibungsverluste wesentlich verringert werden können. Eine besonders vorteilhafte Ausführungsform ist dadurch gegeben, dass die Kolbenvorrichtung als Ringkolben ausgebildet ist. Auch ist es vorteilhaft, wenn auf der Pumpenwelle eine Exzenterscheibe drehfest angeordnet ist, die in Wirkverbindung mit der Radialkolbenpumpe steht.This object is achieved, a locking device for the radial piston pump is provided, with which the radial piston pump from a standby mode in an operating mode and vice versa is switchable. This makes it possible to provide a much more compact and thus space-saving coolant pump, wherein the radial piston pump is switched on only when needed, whereby wear and friction losses can be significantly reduced. A particularly advantageous embodiment is given by the fact that the piston device is designed as an annular piston. It is also advantageous if an eccentric disc is rotatably mounted on the pump shaft, which is in operative connection with the radial piston pump.
Eine besonders vorteilhafte Ausführungsform ergibt sich dadurch, dass die Steuerkanalanordnung einen ersten Steuerkanal zur Verbindung eines ersten Druckraumes der Radialkolbenpumpe mit einem zweiten Steuerkanal aufweist, wobei der zweite Steuerkanal einen zweiten Druckraum der Kolbenvorrichtung mit einem dritten Steuerkanal verbindet, wobei der dritte Steuerkanal den zweiten Steuerkanal mit einem vierten Steuerkanal und dem Ausströmbereich des Laufrades verbindet, wobei der vierte Steuerkanal den dritten Steuerkanal mit dem ersten Druckraum verbindet, wobei ein fünfter Steuerkanal vorgesehen ist, der den Ausströmbereich des Laufrades mit dem ersten Steuerkanal verbindet, wobei im ersten, vierten und fünften Steuerkanal Rückschlagventile angeordnet sind und im zweiten Steuerkanal ein Ventilsitz für das Elektromagnetventil angeordnet ist.A particularly advantageous embodiment results from the fact that the control channel arrangement has a first control channel for connecting a first pressure chamber of the radial piston pump with a second control channel, wherein the second control channel connects a second pressure chamber of the piston device with a third control channel, wherein the third control channel with the second control channel a fourth control channel and the outflow region of the impeller connects, wherein the fourth control channel connects the third control channel with the first pressure chamber, wherein a fifth control channel is provided which connects the Ausströmbereich the impeller with the first control channel, wherein in the first, fourth and fifth control channel check valves are arranged and arranged in the second control channel, a valve seat for the solenoid valve.
In vorteilhafter Weise kann die Arretiervorrichtung eine mit einem Radialkolben der Radialkolbenpumpe in Wirkverbindung stehende Lochscheibe aufweisen, die durch ein weiteres Elektromagnetventil betätigbar ist.Advantageously, the locking device may have a standing with a radial piston of the radial piston pump in operative connection perforated disc which is actuated by a further solenoid valve.
