In order to improve the aerodynamics of a vehicle and to reduce fuel consumption, a brake cooling device having at least one opening of the wheel housing shell is proposed according to the invention, which is aligned in such a way that the cooling air flow is at least partially guided to the brake system after the cooling air flow has flowed through the cooling package.
Description
Beschreibung Luftkühlsvstem Description air cooling system
Die vorliegende Erfindung betrifft ein Kühlsystem zur Luftkühlung einer Bremsanlage und eines Motors eines Fahrzeugs mit einem Kühlpaket, das von einem Kühlluftstrom durchströmbar ist. The present invention relates to a cooling system for air cooling a brake system and an engine of a vehicle with a cooling package, which is flowed through by a cooling air flow.
In Fahrzeugen, insbesondere in Personenkraftwagen (PKW), muss nicht nur der Motor im laufenden Betrieb mittete eines Kühlpaketes gekühlt werden, das hierzu von einem Kühlluftstrom durchströmt wird, um die Motorwärme abzuführen, sondern auch die Bremsaniage, die eine Bremsscheibe und einen Bremssattel umfasst, weil die gesamte Bewegungsenergie des Fahrzeugs beim Bremsvorgang in Form von Wärmeenergie abgegeben wird. Insbesondere die Vorderradbremsen werden beim üblichen Gebrauch von Fahrzeugen stark beansprucht, was eine effiziente Kühlung der Bremsanlage erfordert. In vehicles, especially in passenger cars (PKW), not only the engine must be cooled during operation mittete a cooling pack, which is flowed through by a cooling air flow to dissipate the engine heat, but also the Bremsaniage comprising a brake disc and a brake caliper, because the entire kinetic energy of the vehicle is released during the braking process in the form of heat energy. In particular, the front brakes are heavily stressed in the usual use of vehicles, which requires efficient cooling of the brake system.
In herkömmlichen Fahrzeugen sind zur Kühlung der Bremsanlage Bremskühlkanäle angeordnet, die Kühlluft aus der Umströmung des Fahrzeugs abzweigen und zu der Bremsanlage leiten. Das Kühlpaket des Motors wird unabhängig von den Bremskühlkanälen von einem Kühlluftstrom durchströmt, der an einer anderen Stelle des Fahrzeugs aus der Umströmung abgezweigt wird. In conventional vehicles, brake cooling channels are arranged for cooling the brake system, the cooling air branch off from the flow around the vehicle and lead to the brake system. The cooling package of the engine is flowed through by a cooling air flow independently of the brake cooling channels, which is branched off at another point of the vehicle from the flow around.
Beispielsweise offenbart DE 10 2012 209 980 A1 ein Kühlsystem mit einem solchen Bremskühlkanal mit einem Einlass, der so ausgelegt ist, dass er einen Teil der durch eine vordere Öffnung der Karosserie strömenden Luft unmittelbar zur Bremsanlage leitet, um die Bremsanlage zu kühlen. Der andere Teil der durch die vordere Öffnung der Karosserie strömenden Luft durchströmt das Köhlpaket des Motors und wird nicht gezielt zur Kühlung der Bremsanlage eingesetzt.
NachteiHger Weise wirkt sich ein Eingriff in die Umströmung des Fahrzeugs negativ auf die Aerodynamik des Fahrzeugs aus, womit der Kraftstoffverbrauch des Fahrzeugs steigt und ein Einfiuss auf die Achsentlastung (Auftnebsverteilung) vorgenommen wird. Bei Fahrzeugen mit einem verschließbaren Bremskühlkanal haben Vergleichsmessungen z. B. eine Differenz von ca. 4-10 cw-Punkten ergeben. For example, DE 10 2012 209 980 A1 discloses a cooling system having such a brake cooling passage with an inlet adapted to direct a portion of the air flowing through a front opening of the body directly to the brake system to cool the brake system. The other part of the air flowing through the front opening of the body air flows through the Köhlpaket the engine and is not used specifically for cooling the brake system. Adversely, an intervention in the flow around the vehicle has a negative effect on the aerodynamics of the vehicle, whereby the fuel consumption of the vehicle increases and an influence on the axle unloading (distribution of the load) is made. For vehicles with a lockable brake cooling channel comparative measurements z. B. result in a difference of about 4-10 cw points.
Es ist daher die primäre Aufgabe der vorliegenden Erfindung, ein Kühlsystem zur Luftkühlung einer Bremsanlage und eines Motors zu schaffen, das eine effiziente Kühlung der Bremsanlage ermöglicht, die Aerodynamik des Fahrzeugs verbessert und den Kraftstoffverbrauch reduziert. It is therefore the primary object of the present invention to provide a cooling system for air cooling a brake system and an engine that enables efficient cooling of the brake system, improves the aerodynamics of the vehicle and reduces fuel consumption.
Diese Aufgabe wird durch das Kühlsystem nach Anspruch 1 gelöst, das erfindungsgemäß eine Bremskühleinrichtung mit mindestens einer Öffnung der Radhausschale besitzt, die derart ausgerichtet ist, dass der KüWluftstrom zumindest teilweise zu der Bremsanlage geführt wird, nachdem der Kühlluftstrom das Kühlpaket durchströmt hat. Im einfachsten Fall der Erfindung ist die Bremskühleinrichtung ausschließlich durch die Öffnung der Radhausschale gegeben, die das Radhaus zum Motorraum hin öffnet. Der Luftaustritt erfolgt in diesem Fall ohne eine zusätzliche Luftführung im Motorraum und ergibt sich aus den wirkenden Druckunterschieden. Die konkrete Positionierung der Öffnung der Radhausschale ist von dem Fahrzeug abhängig und entsprechend anpassbar. This object is achieved by the cooling system according to claim 1, which according to the invention has a brake cooling device with at least one opening of the wheel housing, which is aligned such that the KüWluftstrom is at least partially guided to the brake system after the cooling air flow has flowed through the cooling pack. In the simplest case of the invention, the brake cooling device is given exclusively through the opening of the wheel housing shell, which opens the wheel arch to the engine compartment. The air outlet takes place in this case without an additional air flow in the engine compartment and results from the acting pressure differences. The specific positioning of the opening of the wheel arch liner depends on the vehicle and can be adapted accordingly.
Die vorliegende Erfindung nutzt zur Kühlung der Bremsanlage keine zusätzliche Luft aus der Umströmung des Fahrzeugs, sondern die Kühlluft, die ohnehin das Kühlpaket des Motors durchströmt hat und die der Umströmung des Fahrzeugs bereits entzogen wurde, Die Temperatur der Ktihlluft aus dem Motorraum, die das Kühlpaket zuvor durchströmt hat, ist in Bezug auf die Temperatur der Bremsanlage noch so gering, dass eine ausreichende und effiziente Kühlung der Bremsanlage erfolgt. Die Aerodynamik des Fahrzeugs wird durch dieses Kühlsystem nicht negativ beeinflusst, so dass sich eine Reduktion des Kraftstoffverbrauchs im Vergleich zu solchen Fahrzeugen ergibt, bei denen ein zusätzlicher Bremskühlkanal vorgesehen ist, der einen Teil der Umströmung als Kühlluft abzweigt Ferner ist durch diese Maßnahme ein gezielter Auslass der Kühl-
luft aus dem Motorraum möglich, was sich ebenfalls positiv auf die Aerodynamik und mithin den Kraftstoffverbrauch des Fahrzeuges auswirkt. The present invention uses for cooling the brake system no additional air from the flow around the vehicle, but the cooling air, which has already flowed through the cooling package of the engine and the flow around the vehicle has already been withdrawn, the temperature of Ktihlluft from the engine compartment, the cooling package has passed through before, is still so low in terms of the temperature of the brake system that a sufficient and efficient cooling of the brake system takes place. The aerodynamics of the vehicle is not adversely affected by this cooling system, so that there is a reduction in fuel consumption compared to those vehicles in which an additional brake cooling channel is provided, which branches off part of the flow as cooling air Furthermore, by this measure, a targeted outlet the cooling Air from the engine compartment possible, which also has a positive effect on the aerodynamics and thus the fuel consumption of the vehicle.
Ein weiterer wesentlicher Vorteil der Erfindung ergibt sich für den Fall, dass der Motor einen Motorlüfter aufweist, der üblicherweise im Kühlpaket integriert ist und mit dem der Kühlluftmassenstrom erhöht werden kann. Durch Einschalten des Lüfters wird bei geringer Geschwindigkeit und beim Stillstand des Fahrzeugs der Kühlluftstrom zur Bremsanlage aufrechterhalten und sichergestellt Hierdurch ergeben sich bei geringen Geschwindigkeiten und beim Stillstand des Fahrzeugs gegenüber Kühlsystemen nach dem Stand der Technik durch eine erhöhte Kühlleistung Vorteile. Another essential advantage of the invention results in the event that the engine has a motor fan, which is usually integrated in the cooling package and with which the cooling air mass flow can be increased. By switching on the fan, the cooling air flow to the brake system is maintained at low speed and at standstill of the vehicle and ensured This results in low speeds and at standstill of the vehicle over cooling systems according to the prior art by increased cooling benefits.
Vorteilhafte Ausgestaltungen der vorliegenden Erfindung werden im Folgenden und in den Unteransprüchen angegeben. Advantageous embodiments of the present invention are given below and in the subclaims.
Nach einer ersten bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass die Bremskühleinrichtung einen ersten Bremskühlkanal mit einem Einlass und einem Aus- lass aufweist, der in die Öffnung der Radhausschale übergeht. Die Anordnung eines Bremskühikanals bewirkt eine gezielte Umleitung der Kühlluft, womit sich der Wirkungsgrad der Kühlung erhöht. Der Einlass des ersten Bremskühikanals ist auf die Fahrtrichtung des Fahrzeugs bezogen hinter dem Kühlpaket des Motors angeordnet According to a first preferred embodiment of the invention, it is provided that the brake cooling device has a first brake cooling channel with an inlet and an outlet, which merges into the opening of the wheel housing shell. The arrangement of a Bremskühikanals causes a targeted diversion of the cooling air, which increases the efficiency of the cooling. The inlet of the first Bremskühikanals is arranged in the direction of travel of the vehicle behind the cooling pack of the engine
Nach einer weiteren bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass das Kühtsystem innerhalb eines Motorraums eines Fahrzeugs angeordnet ist, dereine Kühliufteinlassöffnung aufweist. Üblicherweise sind solche Kühllufteinfassöffnungen an der Stirnwand am vorderen Ende eines Fahrzeugs angeordnet Hinter der Kühliufteinlassöffnung ist vorzugsweise das Kühlpaket in Form eines Wärmetauschers angeordnet, so dass der Kühlluftstrom passiv durch den Fahrtwind gebildet ist und mithin geschwindigkeitsabhängig ist. Alternativ und/oder additiv ist ein Lüfter vorgesehen, der den Kühlluftstrom aktiv erzeugt und der in Fahrtrichtung gesehen vor oder hinter dem Kühlpaket angeordnet ist. Insbesondere bei langsamen Bergabfahrten, wo der Fahrtwind geschwindigkeitsbedingt gering ist und die Bremsleistung und mithin die abzuführende Wärme vergleichsweise hoch ist, oder auch im Stand der Fahrzeugs, hat sich die Verwendung des Lüfters als besonders vorteilhaft und effizient erwiesen.
Um für alle Fahrsituationen eine optimale Kühlung der Bremsanlage zu ermöglichen, ist nach einer weiterhin bevorzugten Ausgestaltung der Erfindung ein zweiter Bremskühlkanal mit einem Einlass vorgesehen, der derart angeordnet ist, dass der Kühlluftstrom zu der Bremsanlage geleitet wird, ohne dass der Kühlluftstrom das Kühfpaket durchströmt hat. Der zweite Bremskühlkanal weist vorzugsweise eine Einlassöffnung auf, die zum Unterboden des Fahrzeugs hin geöffnet ist. Vorzugsweise sind Verschlusselemente angeordnet, die ein wahlweises Verschließen des ersten und/oder des zweiten Bremskühlkanals erlauben. Mischzustände, bei denen beide Kanäle teilweise oder vollständig geöffnet sind, sind möglich. Durch diese Ausgestaltung kann die Kühlleistung an die gegebene Fahrsituation optimal angepasst werden. According to a further preferred embodiment of the invention it is provided that the cooling system is arranged within an engine compartment of a vehicle having a cooling air inlet opening. Usually, such cooling air intake openings are arranged on the end wall at the front end of a vehicle. The cooling package in the form of a heat exchanger is preferably arranged behind the cooling air inlet opening, so that the cooling air flow is passively formed by the travel wind and is therefore speed-dependent. Alternatively and / or additively, a fan is provided which actively generates the cooling air flow and which, viewed in the direction of travel, is arranged in front of or behind the cooling package. In particular, in slow downhills, where the airflow is low due to speed and the braking power and therefore the dissipated heat is relatively high, or in the state of the vehicle, the use of the fan has proven to be particularly advantageous and efficient. In order to enable optimal cooling of the brake system for all driving situations, according to a further preferred embodiment of the invention, a second brake cooling channel is provided with an inlet which is arranged such that the cooling air flow is passed to the brake system, without the cooling air flow has flowed through the Kühfpaket , The second brake cooling channel preferably has an inlet opening, which is open to the underbody of the vehicle. Preferably, closure elements are arranged, which allow an optional closing of the first and / or the second brake cooling channel. Mixed states where both channels are partially or fully opened are possible. With this configuration, the cooling power can be optimally adapted to the given driving situation.

Fig. 1 zeigt ein Kühlsystem für einen (nicht dargestellten) Motor und eine Bremsanlage 9, wie es in herkömmlichen Fahrzeugen nach dem Stand der Technik angeordnet ist. Hiernach besitzt das Fahrzeug 1 , von dem nur die Vorderseite dargestellt ist, ein Kühlpaket 2, das hinter einer Kühllufteinlassöffnung 3 angeordnet ist und das von Kühlluft bzw. einem Kühlluftstrom 4 durchströmt wird. Der Kühlluftstrom 4 kann durch einen Lüfter 5 unterstützt werden. Separat und unabhängig hiervon ist am Unterboden des Fahrzeugs 1 ein Einlass 6 eines Bremskühlkanals 7 vorgesehen, der Kühlluft von der Umströmung des Fahrzeugs 1 abzweigt und diese Kühlluft zur Bremsanlage 9 leitet (Pfeil 8), was sich in oben beschriebener Weise negativ auf die Aerodynamik des Fahrzeugs 1 auswirkt.
Die Fig. 2a-d zeigen Ausführungsbeispiele der Erfindung. Fig. 2a zeigt den einfachsten Fall einer konkreten Ausführüngsform der Erfindung, wonach sich die Bremskühleinrichtung des Kühlsystems auf eine Öffnung 10 der Radhausschale 11 beschränkt, die das Radhaus 12 zum Motorraum 13 öffnet. Hierdurch wird der Kühlluftstrom 4 zur Kühlung der Bremsanlage 9 weitergeleitet, nachdem er das Kühlpaket 2 durchströmt hat. Fig. 1 shows a cooling system for a (not shown) engine and a brake system 9, as it is arranged in conventional vehicles according to the prior art. After that, the vehicle 1, of which only the front side is shown, has a cooling pack 2 which is arranged behind a cooling air inlet opening 3 and through which cooling air or a cooling air flow 4 flows. The cooling air flow 4 can be supported by a fan 5. Separately and independently thereof, an inlet 6 of a brake cooling channel 7 is provided on the underbody of the vehicle 1, the cooling air branches off from the flow around the vehicle 1 and this cooling air to the brake system 9 passes (arrow 8), which in the manner described above negative to the aerodynamics of Vehicle 1 affects. Figs. 2a-d show embodiments of the invention. Fig. 2a shows the simplest case of a concrete Ausführüngsform the invention, according to which the brake cooling device of the cooling system is limited to an opening 10 of the wheel arch 11, which opens the wheel arch 12 to the engine compartment 13. As a result, the cooling air flow 4 is forwarded for cooling the brake system 9 after it has flowed through the cooling pack 2.
Fig. 2b zeigt eine Weiterbildung der Erfindung, wonach die Bremskühleinrichtung zusätzlich einen ersten Bremskühlkanal 22 aufweist. Die Einlassöffnung 21 des ersten Bremskühlkanals 22 ist in Fahrtrichtung (Pfeil 23) gesehen hinter dem Kühlpaket 2 angeordnet, so dass der KühHuftstrom 4 zunächst das Kühlpaket 2 durchströmt und anschließend über den Bremskühlkanal 22 zu der Bremsanlage 9 geleitet wird. Alternativ kann die Einlassöffnung 21 auch seitlich hinter dem Lüfter 5 positioniert sein, weil der Motorblock (in Fig. 2b nicht gezeigt) den Kühlluftstrom 4 nach dem Austreten aus dem Kühlpaket 2 größtenteils zum seitlichen Umströmen zwingt. Auch sind weitere Positionen der Einlassöffnung möglich, solange gewährleistet wird, dass ein ausreichender KühHuftstrom 4 zur Bremsanlage 9 umgeleitet wird, nachdem der Kühlluftstrom das Kühlpaket 2 durchströmt hat. Auf einen separaten Einiass, der Kühlluft aus der Umströmung des Fahrzeugs 1 abzweigt, kann mithin verzichtet werden, womit sich die angesprochenen Vorteile bezüglich der Aerodynamik und des Kraftstoffverbrauchs des Fahrzeugs 1 ergeben. FIG. 2b shows a development of the invention, according to which the brake cooling device additionally has a first brake cooling channel 22. As seen in the direction of travel (arrow 23), the inlet opening 21 of the first brake cooling channel 22 is arranged behind the cooling pack 2, so that the cooling air stream 4 first flows through the cooling pack 2 and is then guided via the brake cooling passage 22 to the brake system 9. Alternatively, the inlet opening 21 may also be positioned laterally behind the fan 5, because the engine block (not shown in FIG. 2 b) largely forces the cooling air flow 4 after it leaves the cooling package 2 for lateral flow around. Further positions of the inlet opening are possible as long as it is ensured that a sufficient cooling air flow 4 is diverted to the brake system 9 after the cooling air flow has flowed through the cooling packet 2. In a separate Einiass, the cooling air branches off from the flow around the vehicle 1, can therefore be dispensed with, resulting in the mentioned advantages in terms of aerodynamics and fuel consumption of the vehicle 1.
Ergänzend zu dem ersten Bremskühlkanal 22 ist optional ein zweiter Bremskühlkanal 24 vorgesehen, dessen Einiass 25 am Unterboden des Fahrzeugs 1 angeordnet ist. Bei dieser Ausführungsvariante ist ein Verschlusselement 26 in Form einer Klappe vorgesehen, das einen der Bremskühlkanäle 22 oder 24 schließt und den jeweils anderen Bremskühlkanal öffnet, so dass die Kühlung der Bremsanlage 9 an die Fahrsituation anpassbar ist. Fig. 2b zeigt eine Einstellung, bei der der Bremskühlkanal 22 geöffnet ist, während der Bremskühlkanal 24 durch das Verschlusselement 26 geschlossen ist, so dass der Kühlluftstrom 4 zunächst das Kühlpaket 2 durchströmt, bevor es auf die Bremsanlage geleitet wird. Fig. 2c zeigt die umgekehrte Einstellung, bei der das Verschlusselement 26 den Bremskühlkanal 22 schließt und den Bremskühlkanal 24 öffnet.
Fig. 2d zeigt die Ausführungsformen gemäß Fig. 2b und 2c in einer Draufsicht, wobei die zweiten Bremskühlkanäle 24 sowie das Verschlusselement nicht dargestellt sind.
In addition to the first brake cooling channel 22, a second brake cooling channel 24 is optionally provided, the Einiass 25 is disposed on the underbody of the vehicle 1. In this embodiment, a closure element 26 is provided in the form of a flap which closes one of the brake cooling channels 22 or 24 and opens the respective other brake cooling channel, so that the cooling of the brake system 9 can be adapted to the driving situation. 2b shows a setting in which the brake cooling channel 22 is open, while the brake cooling channel 24 is closed by the closure element 26, so that the cooling air flow 4 first flows through the cooling pack 2 before it is passed to the brake system. Fig. 2c shows the reverse setting, in which the closure element 26 closes the brake cooling passage 22 and the brake cooling passage 24 opens. 2d shows the embodiments according to FIGS. 2b and 2c in a plan view, the second brake cooling channels 24 and the closure element not being shown.
