Description
Die Erfindung betrifft eine mit einer Riemenscheibe versehene, regelbare Kühlmittelpumpe für Verbrennungsmotore.The invention relates to a controllable provided with a pulley Coolant pump for internal combustion engines.
Die direkte Kopplung einer Kühlmittelpumpe mit der Kurbelwelle des Motors hat zur Folge, dass der jeweils geförderte Kühlmittelvolumenstrom von der Drehzahl des Motors bestimmt wird. Daher sind, um selbst bei niedriger Drehzahl und hoher Motorbelastung - beispielsweise bei Bergfahrten mit Hänger - eine ausreichende Kühlleistung zu erzielen, bei den nicht regelbaren Kühlmittelpumpen sowohl deren Kühlleistung wie auch deren Antriebsleistung für den normalen Betrieb zwangsläufig stets zu hoch ausgelegt.Has the direct coupling of a coolant pump to the crankshaft of the engine with the result that the coolant volume flow delivered in each case by the Engine speed is determined. Therefore, in order to lower yourself Speed and high engine load - for example when driving uphill Hanger - to achieve a sufficient cooling capacity with the non-controllable Coolant pumps both their cooling capacity and their drive power always designed too high for normal operation.
Um die Nachteile dieser direkt von der Kurbelwelle angetriebenen Kühlmittelpumpe zu beseitigen werden im Stand der Technik regelbare, über eine Riemenscheibe von der Kurbelwelle angetriebene Kühlmittelpumpen für Verbrennungsmotore vorbeschrieben. Generell ist für diese Bauformen kennzeichnend, daß die maximale Drehzahl des Flügelrades der maximalen Drehzahlen der von der Kurbelwelle angetriebenen Pumpenwelle entspricht.To the disadvantages of this directly driven by the crankshaft Eliminating coolant pumps are adjustable in the prior art a pulley driven by the crankshaft coolant pumps Internal combustion engines described above. Generally for these designs characteristic that the maximum speed of the impeller of the maximum Speeds of the pump shaft driven by the crankshaft corresponds.
Diese von der Kurbelwelle angebotene maximale Drehzahl des Flügelrades kann bei den einzelnen im Stand der Technik vorgeschriebenen, regelbaren, von der Kurbelwelle angetriebenen Kühlmittelpumpen, mit den unterschiedlichsten technischen Mitteln reduziert werden.This maximum speed of the impeller offered by the crankshaft can be regulated, regulated, coolant pumps driven by the crankshaft, with the various technical means can be reduced.
Bei Motorstillstand, d. h. bei Stillstand der Kurbelwelle ist eine Regelung der Drehzahl des Flügelrades nicht möglich.When the engine is stopped, i. H. when the crankshaft is at a standstill, the Impeller speed not possible.
So beschreiben beispielsweise die JP 62-210287 A wie auch die DE 197 01 993 A1 unterschiedliche Bauformen von regelbaren, über eine Riemenscheibe angetriebenen Kühlmittelpumpen, welche mittels unterschiedlicher Bauformen von schaltbaren Magnetkupplungen in Abhängigkeit von der Betriebstemperatur des Kühlmittels, eine Verbindung zwischen dem Flügelrad und der Riemenscheibe herstellen.For example, JP 62-210287 A and DE 197 01 describe it 993 A1 different designs of adjustable, via a pulley driven coolant pumps, which use different designs of switchable magnetic clutches depending on the Operating temperature of the coolant, a connection between the impeller and manufacture the pulley.
In einer anderen, in der DE 197 52 372 A 1 vorgestellten Bauform einer regelbaren, von der Kurbelwelle angetriebenen Kühlmittelpumpe, ist das Flügelrad in der Warmlaufphase frei drehbar auf der von der Kurbelwelle angetriebenen Pumpenwelle angeordnet. Erst beim Erreichen der Betriebstemperatur wird dann das Flügelrad durch die Anpresskraft eines Thermoelementes von der Pumpenwelle mitgenommen.In another design, presented in DE 197 52 372 A 1 adjustable coolant pump driven by the crankshaft, that is In the warm-up phase, the impeller rotates freely on the crankshaft driven pump shaft arranged. Only when reaching the Operating temperature is then the impeller by the pressure of a Thermocouple taken from the pump shaft.
All diese von der Kurbelwelle direkt angetriebenen, regelbaren Kühlmittelpumpen erfordern, daß bei Kurbelwellenstillstand und dennoch benötigten Kühlmittelumlauf zusätzliche Pumpen wie beispielsweise Standheizungspumpen oder bei aufgeladenen Motoren auch Nachhitzepumpen eingesetzt werden müssen.All of these controllable, directly driven by the crankshaft Coolant pumps require that at crankshaft standstill and still required coolant circulation additional pumps such as Auxiliary heating pumps or, in the case of supercharged engines, also post-heat pumps must be used.
Darüber hinaus können die bei großvolumige Motoren auftretenden Heißleerlaufprobleme mit diesen im Stand der Technik bekannten, regelbaren, mit einer Riemenscheibe versehenen Kühlmittelpumpen nicht gelöst werden.In addition, those that occur with large-volume engines Hot idling problems with these adjustable, known in the prior art, coolant pumps fitted with a belt pulley cannot be loosened.
In der DE 198 01 160 A1 wird eine keilriemenseitig sehr groß, aber auch verschmutzungsbedingt störanfällig bauende, regelbare Kühlmittelpumpe mit einem über eine Riemenscheibe und eine Rücklaufsperre angetriebenen Flügelrad mit zuschaltbaren Elektromotor vorgestellt.In DE 198 01 160 A1, a V-belt side is very large, but also adjustable, adjustable coolant pump due to contamination one driven by a pulley and a backstop Impeller with switchable electric motor presented.

Der Rotor des Elektromotors ist am äußeren Ende der Pumpenwelle fest mit der Pumpenwelle verbunden und als Außenläufer ausgebildet.The pulley and the stator of the electric motor are in this design connected to each other and via the backstop to the pump shaft coupled. The rotor of the electric motor is at the outer end of the pump shaft firmly connected to the pump shaft and designed as an external rotor.
Der Erfindung liegt die Aufgabe zugrunde, eine mit einer Riemenscheibe versehene, regelbare Kühlmittelpumpe für Verbrennungsmotore zu entwickeln, die die vorgenannten Nachteile des Standes der Technik nicht aufweist, störunanfällig ist, und bei optimiertem Bauraum die Funktion von Standheizungspumpen und/oder Nachhitzepumpen übernehmen kann, gleichzeitig eine Erhöhung der Förderleistung im Hot Idle-Zustand, wie auch eine Erhöhung des Heizungsförderstromes bei kleinen Drehzahlen ermöglicht, zudem eine bessere Motortemperierung bei gleichzeitiger Energieeinsparung bewirkt, die Warmlaufphase des Motors reduziert und die Schadstoffemission senkt.The invention has for its object one with a pulley to develop a provided, controllable coolant pump for internal combustion engines, which does not have the aforementioned disadvantages of the prior art, is not susceptible to faults, and the function of Auxiliary heating pumps and / or post-heat pumps can take over, at the same time an increase in the conveying capacity in the hot idle state, as well enables an increase in the heating flow at low speeds, also better engine temperature control while saving energy causes the engine warm-up phase and reduces pollutant emissions lowers.
