Description

Die Erfindung betrifft einen Wasser/Luft-Kühler für wassergekühlte Verbrennungskraftmaschinen, insbesondere von Nutzfahrzeugen, dessen Kühlerblock einschließlich der Wasserkästen über Seitenteile befestigt wird, die an ihren beiden Enden mit die Wasserkästen seitlich übergreifenden Befestigungslaschen versehen sind, die Öffnungen aufweisen, durch die Verbindungselemente gesteckt sind, die formschlüssig an den Wasserkästen gehalten sind.The invention relates to a water / air cooler for water-cooled internal combustion engines, in particular of commercial vehicles, the radiator block including the water boxes is fastened via side parts which are provided at both ends with fastening tabs which cross the water boxes laterally and which have openings through which connecting elements are inserted that are held in a form-fitting manner on the water tanks.

Es ist bereits ein Wasser/Luft-Kühler dieser Art vorgeschlagen worden (EP-A-115 795, welche unter Artikel 54 (3) EPÜ lällt), bei dem die Seitenteile ohne eine Lötverbindung fest an den Wasserkästen angebracht werden können und zusammen mit den Wasserkästen eine stabile Rahmenkonstruktion für den aus Rohren und Kühllamellen bestehenden Kühlerblock bilden. Bei der bekannten Bauart ist vorgesehen, daß die Wasserkästen mit durchgehenden Öffnungen versehen sind, die mit den als Bohrungen ausgebildeten Öffnungen in den Befestigungslaschen fluchten, so daß Steckbolzen durch die Befestigungslaschen und durch die Wasserkästen hindurchgesteckt werden können.A water / air cooler of this type has already been proposed (EP-A-115 795, which falls under Article 54 (3) EPC), in which the side parts can be firmly attached to the water tanks without a solder connection and together with the Water boxes form a stable frame construction for the radiator block consisting of pipes and cooling fins. In the known type it is provided that the water boxes are provided with through openings which are aligned with the openings formed as bores in the fastening tabs, so that bolts can be inserted through the fastening tabs and through the water boxes.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen solchen Wasser/Luft-Kühler weiterzubilden und insbesondere dann, wenn aus Kunststoff hergestellte Wasserkästen vorgesehen werden, so auszubilden, daß die Montage und die Verbindungselemente vereinfacht werden.The present invention is based on the object of developing such a water / air cooler and, in particular when water boxes made of plastic are provided, such that the assembly and the connecting elements are simplified.

Die Erfindung besteht darin, daß die Verbindungselemente als Zapfen ausgebildet sind, die fest an den Wasserkästen angebracht sind, so daß der Vorgang des Ausrichtens der Bohrungen in den Befestigungslaschen und in den Wasserkästen und das nachfolgende Durchstecken von Verbindungsbolzen überflüssig wird. Diese Ausgestaltung macht es allerdings erforderlich, insbesondere wenn die Befestigungslaschen aus zwei parallel zueinander verlaufenden Laschenteilen bestehen, die den zugeordneten Wasserkasten jeweils beidseitig übergreifen, daß die Befestigungslaschen eine gewisse Elastizität aufweisen, um sich beim Montagevorgang zumindestens soweit aufspreizen zu lassen, daß sie über die Enden der Zapfen schnappen. Zu diesem Zweck werden die Zapfen so ausgebildet, daß sie auf beiden Seiten jeweils nicht mehr von den Außenseiten der Wasserkästen abragen als die Elastizität der Befestigungslaschen dies zuläßt.The invention is that the connecting elements are designed as pins which are fixedly attached to the water boxes, so that the process of aligning the holes in the mounting tabs and in the water boxes and the subsequent insertion of connecting bolts is unnecessary. However, this configuration makes it necessary, especially if the fastening tabs consist of two mutually parallel tab parts, which overlap the associated water box on both sides, that the fastening tabs have a certain elasticity in order to be able to spread at least as far during the assembly process that they extend over the ends snap the cone. For this purpose, the pins are designed so that they do not protrude from the outside of the water boxes on both sides than the elasticity of the fastening tabs allows.

Die neue Ausgestaltung weist den Vorteil auf, daß bei der Montage die Seitenteile nur in einer bestimmten Richtung auf die Enden der Wasserkästen aufgeschoben werden müssen, bis die Zapfen in die zugeordneten Öffnungen einschnappen. Bei Wasser/Luft-Kühlern mit Befestigungslaschen, die als Eckverstärkung ausgebildet und mit je zwei Öffnungen für die Zapfen versehen sind, die in unterschiedlichem Abstand von den Außenseiten der Wasserkästen angebracht sind, ist es besonders vorteilhaft und einfach, wenn der jeweils äußere der beiden Zapfen eine von der Außenseite nach innen ansteigende Auflaufschräge für das zugeordnete Laschenteil besitzt, die dafür sorgt, daß die Laschen sich in dem gewünschten Sinn bis zum Überschnappen über die Bolzen aufspreizen. Diese Ausführung erlaubt es auch in einfacher Weise, die Zapfen einstückig an den Wasserkästen anzuformen. Bei einer Herstellung aus Kunststoff werden die Wasserkästen damit gleich mit den späteren Verbindungsstellen zu den Seitenteilen ausgerüstet.The new design has the advantage that during assembly the side parts only have to be pushed onto the ends of the water boxes in a certain direction until the pins snap into the associated openings. For water / air coolers with fastening tabs, which are designed as corner reinforcements and are each provided with two openings for the pegs, which are attached at different distances from the outside of the water boxes, it is particularly advantageous and simple if the outer of the two pegs has an ascending slope from the outside inwards for the associated tab part, which ensures that the tabs spread in the desired sense until they snap over the bolts. This design also allows the pegs to be integrally formed on the water tanks in a simple manner. In the case of a production from plastic, the water boxes are thus immediately equipped with the later connection points to the side parts.

Bei dieser Ausführung kann der mit der Auflaufschräge versehene Zapfen einen Querschnitt aufweisen, der nicht rotationssymmetrisch ist. Werden die Öffnungen in den Laschenteilen dem Querschnitt dieses Zapfens in der quer zu den mit den Seitenteilen versehenen Außenseiten verlaufenden Montagerichtung angepaßt, dann ergibt sich ein guter Formschluß zwischen Seitenteilen und Wasserkästen. Der nicht mit der Auflaufschräge versehene Zapfen kann rund ausgebildet sein und mit einer die Laschenteile an den Wasserkästen haltenden Sicherungseinrichtung in der Form einer Federklammer versehen sein. Es ist aber auch bei der neuen Ausführung möglich und vorteilhaft, wenn die Sicherungseinrichtung als eine am freien Ende des Zapfens angeordnete, elastisch nachgiebige Rastanordnung ausgebildet ist, die in einfacher Weise aus zwei gegenüberliegenden Rasthaken bestehen kann, die bei einer besonders vorteilhaften Ausführungsform Teil der Seitenwandungen eines mit rechteckigem Querschnitt versehenen Zapfens sind, dessen Zentrum Doppel-T-förmig ausgebildet ist. Auch der zweite Zapfen weist daher eine nicht rotationssymmetrische Form auf. Eine solche Form läßt sich in einfacher Weise aus Kunststoff herstellen. Auch die Art der Rasteinrichtung ist einfach realisierbar. Um schließlich die genaue Lage der Seitenteile an den Wasserkästen sicherzustellen, ist es zweckmäßig, wenn im Bereich außerhalb mindestens eines der Zapfen Rippen vorgesehen sind, deren freie Stirnseiten als Anlageflächen für die Laschenteile der Seitenteile dienen.In this embodiment, the pin provided with the run-up slope can have a cross section that is not rotationally symmetrical. If the openings in the tab parts are adapted to the cross-section of this pin in the assembly direction transverse to the outer sides provided with the side parts, then there is a good positive fit between the side parts and water boxes. The pin which is not provided with the run-up slope can be round and can be provided with a securing device in the form of a spring clip which holds the tab parts on the water tanks. However, it is also possible and advantageous in the new embodiment if the securing device is designed as an elastically flexible latching arrangement which is arranged at the free end of the pin and which can consist in a simple manner of two opposite latching hooks which, in a particularly advantageous embodiment, form part of the side walls a pin with a rectangular cross section, the center of which is double T-shaped. The second pin therefore also has a non-rotationally symmetrical shape. Such a shape can be produced in a simple manner from plastic. The type of locking device is also easy to implement. In order to finally ensure the exact position of the side parts on the water tanks, it is expedient if ribs are provided in the area outside at least one, the free end faces of which serve as contact surfaces for the tab parts of the side parts.

In den Fig. 1 und 2 ist ein Wasser/Luft-Kühler für ein Nutzfahrzeug dargestellt, der aus einem oberen, aus Kunststoff hergestellten Wasserkasten (1') und aus einem ebenfalls aus Kunststoff hergestellten unteren Wasserkasten (2') besteht, zwischen denen in bekannter Weise Rohre zur Führung des Kühlwassers angeordnet sind, von denen nur die Achsen (3) gezeigt sind, die senkrecht zu dem Befestigungsflansch (4') der Wasserkästen (1', 2') verlaufen. Die in Richtung der Achsen (3) angeordneten Rohre sind in bekannter Weise mit Rippen versehen und bilden mit nicht gezeigten Rohrböden einen Kühlerblock, der durch eine Lötverbindung hergestellt ist. Die Rohrböden sind mit dem zugeordneten Flansch (4') der Wasserkästen (1', 2') verbördelt, wie das ebenfalls bekannt ist.1 and 2, a water / air cooler for a commercial vehicle is shown, which consists of an upper, water box made of plastic (1 ') and a lower plastic box (2') also made of plastic, between which in As is known, pipes for guiding the cooling water are arranged, of which only the axes (3) are shown which run perpendicular to the mounting flange (4 ') of the water boxes (1', 2 '). The tubes arranged in the direction of the axes (3) are provided with ribs in a known manner and, together with tube sheets (not shown), form a cooler block which is produced by a soldered connection. The tube sheets are flanged with the associated flange (4 ') of the water tanks (1', 2 '), as is also known.

Zur Befestigung des Kühlers im Nutzfahrzeug dienen die Seitenteile (5', 6'). Diese sind entweder als Profilteile aus Metall hergestellt oder bestehen, ebenso wie die Wasserkästen, aus einem Kunststoff mit genügender Stabilität. Die Seitenteile (5', 6') sind im wesentlichen symmetrisch zu der Mittelebene (7) des Kühlers ausgebildet, weisen aber verschiedenartige Befestigungsvorsprünge auf. Das Seitenteil (5') besitzt eine seitlich abstehende Auflagefläche (8'), die über Befestigungswinkel (9') am Seitenteil (5') angebracht ist. Die Fläche (8') dient zum Abstützen auf einem Teil der Rahmenkonstruktion des nicht gezeigten Fahrzeuges.The side parts (5 ', 6') serve to fasten the radiator in the commercial vehicle. These are either made of metal as profile parts or, like the water boxes, are made of a plastic with sufficient stability. The side parts (5 ', 6') are essentially symmetrical to the central plane (7) of the cooler, but have different types of fastening projections. The side part (5 ') has a laterally projecting bearing surface (8') which is attached to the side part (5 ') by means of fastening brackets (9'). The surface (8 ') is used to support part of the frame structure of the vehicle, not shown.

Das Seitenteil (6') ist mit aus einer profilierten Vertiefung herausragenden Befestigungshaken (10') versehen. Beide Seitenteile weisen außerdem noch Ausprägungen (11') auf, die mit Bohrungen zum Einsetzen von Befestigungsschrauben versehen sind. Diese so ausgebildeten Seitenteile sind sehr stabil. Sie sind am oberen und am unteren Ende mit Befestigungslaschen (12' bzw. 13') versehen, welche den oberen Wasserkasten (1') und den unteren Wasserkasten (2') seitlich übergreifen. Diese Befestigungslaschen (12') bestehen aus jeweils zwei, die Wasserkästen (1', 2') auf ihrer Vorder- und Rückseite übergreifenden Laschenteilen (12a', 12b' bzw. 13a', 13b'). Sie sind durch die Anordnung von schräg verlaufenden Verbindungsstegen (14') als Eckwinkel ausgebildet, welche zur Verstärkung der Seitenteile in diesen Bereichen dienen.The side part (6 ') is provided with fastening hooks (10') protruding from a profiled recess. Both side parts also have features (11 ') which are provided with holes for inserting fastening screws. These side parts designed in this way are very stable. They are provided at the upper and at the lower end with fastening tabs (12 'and 13') which overlap the upper water tank (1 ') and the lower water tank (2'). These fastening tabs (12 ') each consist of two tab parts (12a', 12b 'and 13a', 13b ') spanning the water boxes (1', 2 ') on their front and rear sides. They are formed by the arrangement of inclined connecting webs (14 ') as corner brackets, which serve to reinforce the side parts in these areas.

Aus den Fig. 3 und 4 geht hervor, daß der Wasserkasten (1') - und analog der Wasserkasten (2') - aus einem mit Längs- und Querrippen (30, 31) versehenen und dadurch in diesem Bereich stabil ausgestalteten Kunststoffteil besteht, an dem von beiden Außenseiten (32) nach außen abstehende Zapfen (33) in Form von Hohlstutzen vorgesehen sind, die einstückig aus dem Material des Wasserkastens (1') ausgeformt und, beim Ausführungsbeispiel, mit aus dem Kunststoffmaterial gegossen oder gespritzt sind. Diese Zapfen (33) weisen außerdem im Bereich ihres freien Endes umlaufende Nuten (34) auf, in die die aus der Fig. 4 ersichtlichen Federklammern (35) einrastend eingeschoben sind.3 and 4 that the water tank (1 ') - and analogously to the water tank (2') - consists of a plastic part provided with longitudinal and transverse ribs (30, 31) and thus stably designed in this area, on the pin (33) projecting outward from both outer sides (32) are provided in the form of hollow connecting pieces which are formed in one piece from the material of the water box (1 ') and, in the exemplary embodiment, are cast or injection-molded from the plastic material. These pins (33) also have circumferential grooves (34) in the region of their free end, into which the spring clips (35) shown in FIG. 4 are inserted in a snap-in manner.

Fest an dem Wasserkasten (1') angeformt ist außerdem ein weiterer Zapfen (36) in der Form eines Einpaßzapfens, der, wie insbesondere auch Fig. 1 entnommen werden kann, einen kürzeren Abstand zu den mit den Seitenteilen (5' bzw. 6') versehenen Stirnseiten der Wasserkästen (1' bzw. 2') aufweist. Dieser Zapfen (36) ist mit einer von den Stirnseiten, d. h. also vom zugeordneten Seitenteil (5' bzw. 6') ausgehenden, zur Längsmittelebene (7) des Kühlers ansteigenden Auflaufschräge (37) versehen und aus Herstellungsgründen ebenfalls als ein kurzer Hohlzapfen ausgebildet, der jedoch, im Gegensatz zum Zapfen (33), nicht rund im Querschnitt, sondern rechteckig ausgebildet ist. Dieser Zapfen (36) ragt auch nicht so weit von den Seiten (32) aus nach außen ab, wie der Zapfen (33). Er greift aber formschlüssig in eine entsprechende Öffnung (38) in den Laschenteilen (12a' bzw. 12b') des Seitenteiles (5') ein. Die Anordnung der Befestigungslasche (13') und an dem anderen Seitenteil (6') ist analog. Im Bereich der beiden Zapfen (33, 36) sind am Wasserkasten (1'), natürlich analog auch am Wasserkasten (2') nach außen abstehende Rippen (39) vorgesehen, deren freie Stirnseiten (40) als Anlageflächen für die Laschenteile (12a', 12b') dienen. Die Seitenteile (5' bzw. 6') können daher seitlich auf die Wasserkästen aufgeschoben werden. Dies geschieht beispielsweise mit dem Seitenteil (5') in Richtung des Pfeiles II in der Fig. 1. Die Laschenteile (12a', 12b') laufen bei diesem Montagevorgang mit ihren freien Enden auf die Auflaufschräge (37) des äußeren Zapfens (36) auf und werden auseinandergespreizt. Dies ist möglich, weil die Befestigungslaschen (12' bzw. 13') entsprechend elastisch ausgebildet sind. Fig. 1 zeigt, daß die Befestigungslaschen (12' bzw. 13') im Bereich der Zapfen (33, 36) nicht durch die äußere Stirnwand (41) zusammengehalten sind, sondern parallel zueinander frei abragen. Sie spreizen sich daher beim Aufschieben auf den Zapfen (36) auseinander bis sie mit ihren Öffnungen (38) beim weiteren Aufschiebevorgang über diese Zapfen (36) schnappen, wobei gleichzeitig gemäß den Fig. 1 bis 4 die runden Öffnungen (42) über die freien Seiten der Zapfen (33) in die in Fig. 3 gezeigte Lage schnappen. Es genügt dann, Federklammern (35) aufzuschieben, so daß die Seitenteile (5' bzw. 6') an den Wasserkästen (1', 2') gesichert. sind.Firmly molded onto the water tank (1 ') is also a further pin (36) in the form of a fitting pin, which, as can in particular also be seen in FIG. 1, has a shorter distance from the side parts (5' or 6 ' ) provided end faces of the water tanks (1 'or 2'). This pin (36) is with one of the end faces, i.e. H. So provided from the assigned side part (5 'or 6'), rising to the longitudinal center plane (7) of the radiator slope (37) and also made for manufacturing reasons as a short hollow spigot, which, however, unlike the spigot (33), not round in cross section, but is rectangular. This pin (36) also does not protrude as far from the sides (32) as the pin (33). However, it engages positively in a corresponding opening (38) in the tab parts (12a 'or 12b') of the side part (5 '). The arrangement of the fastening tab (13 ') and on the other side part (6') is analogous. In the area of the two pins (33, 36) on the water tank (1 '), of course analogously also on the water tank (2'), outwardly projecting ribs (39) are provided, the free end faces (40) of which serve as contact surfaces for the tab parts (12a ' , 12b ') serve. The side parts (5 'or 6') can therefore be pushed laterally onto the water tanks. This is done, for example, with the side part (5 ') in the direction of arrow II in FIG. 1. In this assembly process, the tab parts (12a', 12b ') run with their free ends onto the run-up slope (37) of the outer pin (36). on and are spread apart. This is possible because the fastening tabs (12 'or 13') are designed to be correspondingly elastic. Fig. 1 shows that the fastening tabs (12 'and 13') in the region of the pins (33, 36) are not held together by the outer end wall (41), but project freely parallel to one another. They therefore spread apart when pushed onto the pin (36) until they snap with their openings (38) during the further sliding process over these pins (36), with the round openings (42) at the same time according to FIGS. 1 to 4 via the free ones Snap the sides of the pins (33) into the position shown in FIG. 3. It is then sufficient to slide on spring clips (35) so that the side parts (5 'or 6') are secured to the water boxes (1 ', 2'). are.

Im Bereich der Befestigungslaschen (13'), d. h. an der Unterseite der Seitenteile (5'. 6'), ist jeweils ein Festlager vorgesehen. Hier korrespondieren die Abmessungen der Öffnungen (38, 42) in den Befestigungslaschen (12' bzw. 13') mit den Außenabmessungen der Zapfen (33, 36). Im oberen Bereich der Befestigungslaschen (12') ist dies quer zur Längsmittelebene (7) ebenfalls der Fall. In Richtung der Längsmittelebene (7) ist jedoch zwischen den Seitenteilen (5', 6') und dem oberen Wasserkasten (1') ein sogenanntes Loslager gebildet.In the area of the fastening tabs (13 '), d. H. a fixed bearing is provided on the underside of the side parts (5 '. 6'). Here, the dimensions of the openings (38, 42) in the fastening tabs (12 'and 13') correspond to the outer dimensions of the pins (33, 36). In the upper area of the fastening tabs (12 '), this is also the case transversely to the longitudinal center plane (7). In the direction of the longitudinal center plane (7), however, a so-called floating bearing is formed between the side parts (5 ', 6') and the upper water tank (1 ').

Die Ausführungsform der Fig. 5 bis 7 entspricht jener der Fig. 1 bis 4, jedoch mit dem Unterschied, daß hier die Sicherung der Laschenteile (12a', 12b') der Seitenteile (5' bzw. 6') nicht durch eine Federklammer (35) erfolgt, sondern durch eine federnd ausgebildete Rasteinrichtung an dem dem Zapfen (33) entsprechenden Inneren, d. h. zur Längsmittelebene (7) hin gewandten Zapfen. Die übrige Ausbildung entspricht jener der Ausführungsform der Fig. 1 bis 4. Für die entsprechenden Teile sind daher auch die gleichen Bezugszeichen gewählt. Der, zur Längsmittelebene (7) hin gerichtete Zapfen (45) der Ausführungsform der Fig. 5 bis 7 besitzt im Gegensatz zum Zapfen (33) einen in etwa rechteckigen Außenquerschnitt, der aus den beiden Außenwänden (46) eines Doppel-T-Mittelteiles (47) gebildet wird. Die beiden übrigen, den Gesamtquerschnitt zu einem Rechteckquerschnitt ergänzenden Wandteile werden von federnden Rasthaken (48) gebildet, die an ihren äußeren Enden mit hakenförmigen Nasen (49) versehen. sind, die durch die Öffnungen (42) in den Laschenteilen (12a', 12b') durchgreifen und diese nach dem Einrasten fest an den Anlageflächen (40) der Rippen (39) halten. Diese Ausführungsform läßt sich daher ohne einen zusätzlichen Arbeitsvorgang dadurch montieren, daß die Seitenteile (5', 6') seitlich auf die Wasserkästen aufgeschoben werden, wobei die Laschenteile (12a', 12b') sich an der Auflaufschräge (37) des Zapfens (36) aufspreizen und dann über die freien Enden der fest mit den Wasserkästen (1', 2' bzw. 1", 2") verbundenen und frei abstehenden Zapfen (36, 45) mit ihren Öffnungen (38, 42) überschnappen. Dabei werden die beiden Rasthaken (48), die einander gegenüberliegen, eines jeden Zapfens (45) nach innen gedrückt, bis sie über die Außenfläche der Laschenteile (12a', 12b') greifen und so die Befestigungslaschen fest an den Anlageflächen (40) der Rippen (39) halten.The embodiment of FIGS. 5 to 7 corresponds to that of FIGS. 1 to 4, but with the difference that that here the securing of the tab parts (12a ', 12b') of the side parts (5 'or 6') is not carried out by a spring clip (35), but by a resilient locking device on the interior corresponding to the pin (33), ie for Longitudinal center plane (7) facing pin. The remaining design corresponds to that of the embodiment of FIGS. 1 to 4. The same reference numerals are therefore chosen for the corresponding parts. The pin (45) directed towards the longitudinal center plane (7) of the embodiment of FIGS. 5 to 7, in contrast to the pin (33), has an approximately rectangular outer cross section, which consists of the two outer walls (46) of a double-T middle part ( 47) is formed. The two remaining wall parts, which complement the overall cross section to form a rectangular cross section, are formed by resilient latching hooks (48) which have hook-shaped lugs (49) at their outer ends. are, which pass through the openings (42) in the tab parts (12a ', 12b') and hold them firmly after the engagement on the contact surfaces (40) of the ribs (39). This embodiment can therefore be assembled without an additional work process in that the side parts (5 ', 6') are pushed laterally onto the water tanks, the tab parts (12a ', 12b') resting on the run-up slope (37) of the pin (36 ) spread out and then snap over their free ends (36, 45) with their openings (38, 42) over the free ends of the pins (36, 45) which are firmly connected to the water boxes (1 ', 2' or 1 ", 2"). The two locking hooks (48), which are opposite each other, of each pin (45) are pressed inwards until they grip over the outer surface of the tab parts (12a ', 12b') and thus the fastening tabs firmly on the contact surfaces (40) Hold the ribs (39).
