Abstract

A suspension mechanism is provided for a hinged part, such as the engine hood of an agricultural tractor. The top of the engine hood is pivoted on an axle via a forked bearing. A follower on the bottom of the engine hood is guided in a track on the vehicle tractor frame. A support strut is provided at the front end of the hood. So long as the support strut is attached, the hood can pivot about the axle and the follower will move in the guide track on the frame, but the hood cannot be removed because the follower cannot leave the track. To remove the engine hood, the support strut is detached from the hood. The follower then can pivot entirely free of the track and the hood can simply be lifted off of the axle support. The support strut preferably is an outwardly biased pre-loaded gas pressurized spring reaching its shortest length somewhere between the open and closed positions of the hood. The spring then will bias the hood towards its open and closed positions.

Description

Die Erfindung betrifft eine Aufhängung eines Schwenkteils an einem Rahmen oder dergleichen, insbesondere einer Motorhaube eines Kraftfahrzeuges, der einenends frei in einer Richtung geschwenkt werden kann.The invention relates to a suspension of a pivot part on a frame or the like, in particular a hood of a motor vehicle, which can be pivoted freely in one direction at one end.

Eine derartige Aufhängung (DE-OS 2 642 110) findet ihre Anwendung etwa bei einer Motorhaube eines Ackerschleppers und ist derart ausgebildet, daß diese Motorhaube an der Vorderseite des Ackerschleppers zu Wartungszwecken angehoben werden kann. An ihrem rückseitigen Ende ist die Motorhaube mittels eines einfachen Scharniers schwenkbar gehalten. In ihrem frontseitigen Endbereich wird die angehobene Motorhaube über eine gewöhnliche Stange als Stützglied abgestützt.Such a suspension (DE-OS 2 642 110) is used, for example, in the hood of an agricultural tractor and is designed in such a way that this hood can be raised on the front of the agricultural tractor for maintenance purposes. At its rear end, the hood is pivotally held by means of a simple hinge. In its front end area, the raised bonnet is supported as a support member via an ordinary rod.

Dieser Aufhängung haftet der Nachteil an, daß die Motorhaube für Wartungsarbeiten, die eine bessere Zugänglichkeit zu beispielsweise dem Motor erfordern, nur über eine Demontage des Scharniers entfernt werden kann. Dieser Vorgang ist jedoch zeitraubend und erfordert zudem geeignete Werkzeuge.This suspension has the disadvantage that the hood can only be removed for maintenance work that requires better accessibility to the engine, for example, by dismantling the hinge. However, this process is time-consuming and also requires suitable tools.

Die der Erfindung zugrunde liegende Aufgabe wird darin gesehen, die Aufhängung derart zu verbessern, daß der Schwenkteil, und zwar insbesondere die Motorhaube, einfacher und schneller entfernt werden kann.The object on which the invention is based is seen in improving the suspension in such a way that the pivoting part, in particular the bonnet, can be removed more easily and quickly.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst worden, daß der Schwenkteil anderenends in einer Richtung bis zur Anlage an einem Anschlag beweglich auf einem Lager getragen ist.This object has been achieved according to the invention in that the pivoting part is movably supported on a bearing at one end in one direction up to abutment against a stop.

Auf diese Weise ist der Schwenkteil gegen ein unbeabsichtigtes Lösen mittels des Anschlages gehalten, und er kann für Wartungszwecke von dem Lager genommen werden, wenn er außer Eingriff mit dem Anschlag gebracht wird.In this way, the pivoting part is held against inadvertent release by means of the stop and can be removed from the bearing for maintenance purposes when it is disengaged from the stop.

Ein beabsichtigtes Außer-Eingriff-Bringen des Schwenkteils mit dem Anschlag kann entfallen, wenn die hervorragende Lehre nach Anspruch 2 angewendet wird, da dann der Schwenkteil automatisch von dem Anschlag frei wird und von dem Lager genommen werden kann, wenn er ein bestimmtes Maß bewegt worden ist.An intended disengagement of the pivoting part with the stop can be omitted if the excellent teaching according to claim 2 is applied, since then the pivoting part is automatically released from the stop and can be removed from the bearing when it has been moved a certain amount is.

Eine vorteilhafte Ausführung des Anschlages und des Lagers bzw. Weiterentwicklungen davon werden durch die Verwirklichung der Merkmale der Patentansprüche 3 bis 6 erreicht.An advantageous embodiment of the stop and the bearing or further developments thereof are achieved by realizing the features of claims 3 to 6.

Durch die Verwendung einer Gasdruckfeder als Stützglied wird ein automatisches Öffnen des Schwenkteils erreicht, und sofern nach Patentanspruch 8 vorgegangen wird, findet auch ein automatisches Schließen, zumindest aber ein Geschlossen-Halten des Schwenkteils statt.By using a gas pressure spring as a support member, an automatic opening of the swivel part is achieved, and if the procedure is as claimed in claim 8, the swivel part is also automatically closed, or at least kept closed.

Zur Einsparung von Fertigungskosten kann nach einer weiteren Fortentwicklung der Erfindung vorgesehen werden, daß der Führungsteil und die Lasche auf einem Bügel vorgesehen sind, der vorgefertigt und anschließend an dem Schwenkteil befestigt werden kann. Dieser Bügel kann außerdem so ausgebildet sein, daß er an verschieden großen Abdeckungen angebracht werden kann. Selbstverständlich kann anstatt eines Bügels, der beispielweise in eine Motorhaube eingesetzt wird, auch ein flacher Rahmen verwendet werden, der an einer anderen Abdeckung durch Schweißen oder Schrauben befestigt wird.To save manufacturing costs, it can be provided according to a further development of the invention that the guide part and the tab are provided on a bracket that can be prefabricated and then attached to the swivel part. This bracket can also be designed so that it can be attached to covers of different sizes. Of course, instead of a bracket that is used, for example, in a bonnet, a flat frame can also be used, which is attached to another cover by welding or screwing.

Schließlich werden durch die Anbringung einer Strebe zwischen der Querstange und einem Befestigungspunkt des Stützgliedes durch die Wirkung der Gasdruckfeder entstehende Kräfte optimal aufgefangen.Finally, by attaching a strut between the crossbar and an attachment point of the support member, the forces generated by the action of the gas pressure spring are optimally absorbed.

In der Zeichnung ist ein nachfolgend näher beschriebenes Ausführungsbeispiel der Erfindung dargestellt, wobei die einzige Figur einen Schwenkteil in mehreren Stellungen in Seitenansicht zeigt.In the drawing, an embodiment of the invention described in more detail below is shown, the single figure showing a pivoting part in several positions in a side view.

Eine Aufhängung 10 eines Schwenkteils 12 weist ein Lager 14 und einen Anschlag 16 auf. Außerdem ist ein Stützglied 18 vorgesehen. In einer Seitenansicht zu der Zeichnung würde man erkennen, daß die Aufhängung 10 und der Schwenkteil 12 symmetrisch zu einer Längsmittenebene ausgebildet sind.A suspension 10 of a swivel part 12 has a bearing 14 and a stop 16. A support member 18 is also provided. In a side view of the drawing, one would recognize that the suspension 10 and the swivel part 12 are formed symmetrically to a longitudinal center plane.

Der Schwenkteil 12, der in diesem Ausführungsbeispiel von einer Motorhaube eines Ackerschleppers gebildet wird, weist einen U-förmigen Querschnitt in der Blickrichtung auf und ist einenends, und zwar an dem vorderen und in der Zeichnung rechts gelegenen Ende, geschlossen. In seinem vorderen Endbereich ist an seiner Innenseite eine Lasche 20 mit einer Bohrung 22 angebracht, in die ein nicht gezeigter Haltebolzen zur Befestigung eines Endes des Stützgliedes 18 eingesetzt werden kann. In seinem rückwärtigen Endbereich ist an seiner Unterseite ein Bügel 24 eingeschweißt, der zum einen zur Versteifung des Schwenkteils 12 dient und zum anderen Teile des Lagers 14 und des Anschlages 16 aufnimmt, wie dies später noch beschrieben wird. Schließlich können an der Vorderseite des Schwenkteils 12 noch nicht gezeigte Verschlußelemente vorgesehen sein, die den Schwenkteil 12 in seiner unteren Endstellung festhalten.The swivel part 12, which in this exemplary embodiment is formed by a hood of an agricultural tractor, has a U-shaped cross section in the viewing direction and is closed at one end, namely at the front end and on the right in the drawing. In its front end region, a tab 20 with a bore 22 is attached to its inside, into which a retaining bolt, not shown, can be inserted for fastening one end of the support member 18. In its rear end region, a bracket 24 is welded onto its underside, which serves on the one hand to stiffen the swivel part 12 and on the other hand accommodates parts of the bearing 14 and the stop 16, as will be described later. Finally, not yet shown closure elements can be provided on the front of the swivel part 12, which hold the swivel part 12 in its lower end position.

Das Lager 14 ist aus einer Querachse 26 und aus einer Lasche 28 zusammengesetzt, wobei die Lasche 28 an dem Bügel 24 und die Querachse 26 an einem nicht dargestellten Rahmen, der den Schwenkteil 12 insgesamt trägt, befestigt sind und wobei die Querachse 26 parallel zu der Schwenkachse des Schwenkteils 12 verläuft.The bearing 14 is composed of a transverse axis 26 and a tab 28, the tab 28 on the bracket 24 and the transverse axis 26 are attached to a frame, not shown, which carries the pivot part 12 as a whole, and the transverse axis 26 parallel to the Pivot axis of the pivot part 12 runs.

Die Lasche 28 ist gabelförmig mit zwei Schenkeln 30 ausgebildet, die zwischen sich einen ausreichenden Zwischenraum zur Aufnahme der Querachse 26 belassen. Der von den Schenkeln 30 geschaffene Zwischenraum ist etwas tiefer als der Durchmesser der Querachse 26, d. h. sie stehen über die Querachse 26 vor. Auf der Breite des Schwenkteils 12 können je nach Bedarf eine oder mehrere miteinander fluchten de Laschen 28 vorgesehen sein, die alle die Querachse 26 übergreifen. Die Laschen 28 sind so mit Bezug auf das rückseitige Ende des Schwenkteils 12 angeordnet, daß sie einen gewissen Abstand dazu, z. B. ca. 10 cm, aufweisen.The tab 28 is fork-shaped with two legs 30, which leave sufficient space between them for receiving the transverse axis 26. The space created by the legs 30 is somewhat deeper than the diameter of the transverse axis 26, ie they protrude beyond the transverse axis 26. On the width of the swivel part 12, one or more can be aligned with one another as required de tabs 28 may be provided, which all overlap the transverse axis 26. The tabs 28 are arranged with respect to the rear end of the pivot member 12 that they are a certain distance from it, for. B. about 10 cm.

Die Querachse 26 ist ein einfacher Rundstahl, der in diesem Ausführungsbeispiel horizontal und quer zur Fahrtrichtung des den Schwenkteil 12, also die Motorhaube, tragenden Fahrzeuges angeordnet ist.The transverse axis 26 is a simple round steel bar which, in this exemplary embodiment, is arranged horizontally and transversely to the direction of travel of the vehicle carrying the swivel part 12, that is to say the bonnet.

Der Anschlag 16 ist aus einer Führung 32 und einem in dieser geführten Führungsteil 34 gebildet. Hiervon ist der Führungsteil 34 wiederum an dem Bügel 24 und die Führung 32 an dem Rahmen angebracht.The stop 16 is formed from a guide 32 and a guide part 34 guided therein. Of these, the guide part 34 is in turn attached to the bracket 24 and the guide 32 to the frame.

Die Führung 32 enthält eine in eine Platte 36 eingearbeitete Führungsbahn 38, die zunächst horizontal und anschließend leicht ansteigend verläuft. Der Verlauf der Führungsbahn 38 entspricht im wesentlichen einem Abschnitt eines Kreises um die Querachse 26 und somit um das Lager 14. In diesem Ausführungsbeispiel ist auf jeder Seite des Schwenkteils 12 eine Führung 32 vorgesehen.The guide 32 contains a guide track 38 which is worked into a plate 36 and which initially runs horizontally and then rises slightly. The course of the guide track 38 corresponds essentially to a section of a circle around the transverse axis 26 and thus around the bearing 14. In this exemplary embodiment, a guide 32 is provided on each side of the swivel part 12.

Der Führungsteil 34 hat die Form eines Bolzens mit einem Schaftteil 40 und einem Bund 42, wobei der Durchmesser des Schaftteils 40 etwas geringer ist als die Weite der Führungsbahn 38 und der Führungsteil 34 so in der Führungsbahn 38 gleiten kann. Der Bund 42 sorgt dafür, daß der Schwenkteil einen seitlichen Halt erfährt. Die Länge der Führungsbahn 38 ist so bemessen, daß der Schaftteil 40 die Führungsbahn 38 verläßt, wenn die Abdeckung um ca. 30° angehoben worden ist.The guide part 34 has the shape of a bolt with a shaft part 40 and a collar 42, the diameter of the shaft part 40 being slightly smaller than the width of the guide track 38 and the guide part 34 being able to slide in the guide track 38. The collar 42 ensures that the pivoting part experiences a lateral hold. The length of the guide track 38 is dimensioned such that the shaft part 40 leaves the guide track 38 when the cover has been raised by approximately 30 °.

Das Stützglied 18 erstreckt sich von einem Lagerpunkt 44 auf dem Rahmen einerseits zu der an der Unterseite des Schwenkteils 12 vorgesehenen Lasche 20 andererseits und nimmt bei einer Gasdruckfeder seine kürzeste Länge, in der sie zugleich die größte Vorspannung hat, entweder kurz vor Erreichen seiner unteren Endstellung oder in dieser ein. Erreicht die als Stützglied 18 ausgebildete Gasdruckfeder ihre kürzeste Länge bereits vor der unteren Endstellung des Schwenkteils 12 und verlängert es sich wieder bis zu dieser Endstellung, so passiert es eine Totpunktstellung, in der es an sich wirkungslos ist. Nach der Überwindung dieser Totpunktstellung ist das Stützglied 18 bestrebt, sich wieder zu verlängern, was zur Folge hat, daß es den Schwenkteil 12 nach unten zieht. Das Stützglied 18 kann anstatt als Gasdruckspeicher natürlich auch als eine einfache Stützstange ausgebildet sein, wobei dann aber die vorteilhaften Wirkungen durch den Gebrauch der Gasdruckfeder wegfallen.The support member 18 extends from a bearing point 44 on the frame on the one hand to the tab 20 provided on the underside of the swivel part 12 and takes its shortest length in the case of a gas pressure spring in the it also has the greatest preload, either shortly before reaching its lower end position or in this one. If the gas pressure spring designed as a support member 18 already reaches its shortest length before the lower end position of the swivel part 12 and if it extends again to this end position, a dead center position occurs in which it is ineffective. After overcoming this dead center position, the support member 18 strives to lengthen again, with the result that it pulls the pivoting part 12 downward. The support member 18 can of course also be designed as a simple support rod instead of a gas pressure accumulator, but then the advantageous effects are eliminated by the use of the gas pressure spring.

Obwohl es in der Zeic hnung nicht dargestellt ist, kann zwischen dem Lagerpunkt 44 und der Querachse 26 eine Strebe vorgesehen sein, die die durch den Gebrauch der Gasdruckfeder entstehenden Kräfte aufnimmt.Although it is not shown in the drawing, a strut can be provided between the bearing point 44 and the transverse axis 26 which absorbs the forces generated by the use of the gas pressure spring.

Aus der vorangegangenen Beschreibung wie auch aus der Zeichnung geht die Funktion der erfindungsgemäßen Aufhängung wie folgt hervor.From the preceding description as well as from the drawing, the function of the suspension according to the invention follows as follows.

Es wird davon ausgegangen, daß sich der Schwenkteil 12 in seiner unteren Endstellung befindet, wie sie in der Zeichnung in ausgezogenen Linien dargestellt ist, und daß als Stützglied 18 eine Gasdruckfeder verwendet wird.It is assumed that the pivot part 12 is in its lower end position, as shown in solid lines in the drawing, and that a gas pressure spring is used as the support member 18.

Der Schwenkteil 12 wird an seinem frontseitigen Endbereich ergriffen und angehoben, gegebenenfalls nachdem die Verschlußelemente geöffnet worden sind. Wenn der Schwenkteil 12 so weit angehoben worden ist, daß das Stützglied 18 seine Totpunktstellung überwunden hat, dann verlängert sich die Gasdruckfeder und schwenkt den Schwenkteil 12 nach oben. Während der Schwenkteil 12 nach oben schwenkt, bewegt sich der Schaftteil 40 des Führungsteils 34 in der Führungsbahn 38, bis er an deren offenem Ende angelangt ist. Die Lasche 28 des Lagers 14 hebt sich leicht von der Querachse 26 ab, verhindert aber, daß der Schwenkteil 12 durch die Gasdruckfeder nach vorne, d. h. in der Zeichnung nach rechts, gezogen werden kann. Hat der Schwenkteil 12 nun seine obere Endstellung erreicht, die für normale Wartungsarbeiten völlig ausreichend ist, dann hält er in dieser inne, weil die Gasdruckfeder ihr maximale Länge erreicht hat.The swivel part 12 is gripped and raised at its front end region, if necessary after the closure elements have been opened. If the swivel part 12 has been raised so far that the support member 18 has overcome its dead center position, then the gas pressure spring extends and swivels the swivel part 12 upwards. While the swivel part 12 swivels upwards, the shaft part 40 of the guide part 34 moves in the Guideway 38 until it has reached its open end. The tab 28 of the bearing 14 stands out slightly from the transverse axis 26, but prevents the pivoting part 12 from being pulled forward by the gas pressure spring, ie to the right in the drawing. If the swivel part 12 has now reached its upper end position, which is completely sufficient for normal maintenance work, then it stops because the gas pressure spring has reached its maximum length.

Soll der Schwenkteil 12 vollkommen demontiert werden, dann ist der das Stützglied 18 (Gasdruckspeicher) mit dem Schwenkteil 12 verbindende Haltebolzen aus der Lasche 20 zu entnehmen. Anschließend kann der Schwenkteil 12 weiter nach oben geschwenkt werden, wobei der Schaftteil 40 aus der Führungsbahn 38 austritt, so daß der Schwenkteil 12 anschließend nach oben weggenommen werden kann. Der Schwenkteil 12 ist dann vollkommen von dem Rahmen losgelöst, wenn die Lasche 28 die Querachse 26 nicht mehr übergreift. Um den Schwenkteil 12 wieder auf den Rahmen aufzusetzen, ist lediglich in umgekehrter Reihenfolge vorzugehen. Dadurch, daß die Lasche 28 einen Abstand zu dem rückwärtigen Ende des Schwenkteils 12 einnimmt, führt die rückwärtige Kante des Schwenkteils 12 während des Schwenkvorgangs eine Bewegung auf einem Kreisbogen durch, aufgrund welcher sich der Schwenkteil 12 von einem evtl. an ihn angrenzenden Aufbau, wie etwa eine Kabine, wegbewegt. If the swivel part 12 is to be completely disassembled, then the holding bolt connecting the support member 18 (gas pressure accumulator) to the swivel part 12 can be removed from the tab 20. The swivel part 12 can then be swiveled further upwards, the shaft part 40 emerging from the guide track 38, so that the swivel part 12 can then be removed upwards. The pivot part 12 is then completely detached from the frame when the tab 28 no longer overlaps the transverse axis 26. In order to put the swivel part 12 back on the frame, it is only necessary to proceed in the reverse order. Due to the fact that the tab 28 is at a distance from the rear end of the pivot part 12, the rear edge of the pivot part 12 performs a movement on a circular arc during the pivoting process, due to which the pivot part 12 may have a structure adjacent to it, such as about a cabin, moved away.
