Aus der DE 41 09 971 A1 ist ein gattungsgemäßes Fahrwerk mit Laufrädern auf beiden Seiten einer I-förmigen Fahrschiene bekannt, an der vordere und hintere seitliche, auf senkrechten Achsen gelagerte Führungsrollen einseitig anliegen. Dieses Fahrwerk läuft auch bei pendelnder Last stabil auf der Trägerschiene. Trotzdem ist die Fahrstabilität begrenzt; in kritischen Situationen neigt das Fahrwerk etwas zu Nickbewegungen und seitlichem Pendeln.From DE 41 09 971 A1 a generic chassis with wheels is on known on both sides of an I-shaped rail, on the front and rear lateral guide rollers, supported on vertical axes, rest on one side. This Chassis runs stably on the carrier rail even when the load is swinging. Still it is Driving stability limited; in critical situations the chassis tilts a little Nodding movements and sideways swinging.
Es ist Aufgabe der vorliegenden Erfindung, ein Fahrwerk, insbesondere für Kettenzüge und/oder Schleppkabel anzugeben, das auch bei pendelnder Last stabil auf der Trägerschiene läuft, also nicht zu Nickbewegungen und seitlichem Pendeln des Fahrwerks neigt. It is an object of the present invention to provide a trolley, in particular for chain hoists and / or to specify trailing cable that is stable on the Carrier rail runs, so no pitching movements and sideways oscillation of the Landing gear tends.
Die Lösung dieser Aufgabe ist erfindungsgemäß gekennzeichnet durch die im Patentanspruch 1 angegebenen Merkmale. Durch die kennzeichnenden Merkmale der Unteransprüche 2 bis 9 ist das Fahrwerk in vorteilhafter Weise weiter ausgestaltet.The solution to this problem is characterized by the im Claim 1 specified features. Due to the characteristic features of the The claims are further developed in an advantageous manner.
Die Lösung sieht vor, daß die Führungsräder in zumindest an einer Seite des Stegs des Fahrschienenquerschnitts angeordneten Führungen zumindest abschnittsweise geführt sind. Das Fahrwerk ermöglicht insbesondere bei pendelnder Last einen stabilen Lauf auf der Fahrschiene; Nickbewegungen und seitliches Pendeln des Fahrwerks werden durch die Führungen wirkungsvoll verhindert.The solution provides that the guide wheels in at least one side of the web of the guide rail cross section arranged guides at least in sections are led. The chassis enables one, especially with a swinging load stable running on the running rail; Nodding movements and lateral oscillation of the Chassis are effectively prevented by the guides.
Zur Vereinfachung der Herstellung sind die Führungen als Führungsnuten ausgebildet.To simplify production, the guides are designed as guide grooves.
Eine stabile und ruhige Führung wird dadurch erzielt, daß die Kontur der Führungsnuten zur Form der in den Führungsnuten laufenden Führungsräder komplementär ist.A stable and quiet guidance is achieved in that the contour of the Guide grooves for the shape of the guide wheels running in the guide grooves is complementary.
Es wird vorgeschlagen, daß der Querschnitt der Führungsnuten im wesentlichen trapezförmig ausgebildet ist, um zusätzlich einen möglichst geringen Verschleiß der Führungsräder zu erzielen.It is suggested that the cross-section of the guide grooves be substantial is trapezoidal in order to additionally minimize wear To achieve guide wheels.
Insbesondere wird vorgeschlagen, daß die Kanten der Führungsräder abgerundet ausgebildet sind, also nur teilweise auf den Flächen der Führungsnuten laufen.In particular, it is proposed that the edges of the guide wheels be rounded are formed, so run only partially on the surfaces of the guide grooves.
Eine Stabilisierung der Führung bei geringem Verschleiß ergibt sich speziell dann, wenn die Rundung der Kanten der Führungsräder und die Form der trapezförmigen Führungsnuten derart ausgebildet ist, daß die Führungsräder auf den Schrägen der trapezförmigen Führungsnuten laufen, unter Belassung eines Zwischenraums zwischen den Führungsrädern und dem mittleren Bereich der zugehörigen Führungsnut.The guide is stabilized with little wear, especially when if the rounding of the edges of the guide wheels and the shape of the trapezoidal Guide grooves are designed such that the guide wheels on the slopes of trapezoidal guide grooves run, leaving a gap between the guide wheels and the central area of the associated Guide groove.
Ein gleichmäßiger Lauf wird auch dadurch erreicht, daß die Horizontalführungsrollenpaare in den Führungen am Steg des Fahrschienenquerschnitts kraftbeaufschlagt anliegen, beispielsweise durch eine Federkraft hervorgerufen.A smooth run is also achieved in that the Horizontal guide roller pairs in the guides on the web of the Contact rail cross section apply force, for example by a Spring force.
Der Lauf wird insbesondere dadurch verbessert, daß paarweise auf- oder zuschwenkbare Radträgerarme um eine sich in Richtung der Fahrschiene erstreckende und unter dem Fahrschienenquerschnitt verlaufende Achse schwenkbar gelagert sind, wobei auf Höhe oder unterhalb des gebildeten Gelenks der jeweils miteinander verbundenen Radträgerarme die Last an zumindest einem der Radträgerarme angreift und die Radträgerarme durch ein von der Last herrührendes Schließmoment von den in den Führungen am Steg beidseitig anliegenden Führungsrollen begrenzt am Fahrschienenquerschnitt eingeschwenkt gehalten sind.The run is particularly improved in that up or in pairs Swiveling wheel carrier arms around in the direction of the running rail extending and pivoting under the cross section of the running rail are stored, the height at or below the joint formed interconnected wheel carrier arms the load on at least one of the Engages the wheel carrier arms and the wheel carrier arms by one coming from the load Closing moment of those in the guides on the web on both sides Guide rollers are kept pivoted in on the cross section of the guide rail.

In Fig. 1 ist in Vorderansicht ein Fahrwerk dargestellt, das eine Fahrschiene 1 umfaßt,
die aus Flanschteilen 2 und einem Steg 3 besteht. Das Fahrwerk selbst weist zwei
Radträgerarme 4a, 4b auf, die als Rahmen 5a, 5b ausgebildet sind. Die Rahmen 5a,
5b sind um eine sich in Richtung der Fahrschiene 1 erstreckende und unter dem
Fahrschienenquerschnitt verlaufende Achse 6 schwenkbar gelagert, was ein Auf- oder
Zuschwenken der Rahmen 5a, 5b ermöglicht. Selbstverständlich ist das nur eine
vorteilhafte Ausführungsform; die Radträgerarme 4a, 4b können auch starr
miteinander verbunden sein. Darüberhinaus ist auch eine Kombination dieser beiden
Varianten denkbar, die darin besteht, daß die schwenkbaren Radträgerarme 4a, 4b
nach dem einschwenken an der Fahrschiene 1 so fixiert werden, daß eine starre
Verbindung zwischen den Radträgerarmen 4a, 4b hergestellt ist. In Fig. 1, a chassis is shown in front view, which comprises a rail 1,
which consists of
Fig. 1 läßt erkennen, daß im oberen Bereich der Rahmen 5a, 5b ein Paar sich
gegenüberliegender Laufräder 7 angeordnet sind, deren Drehachsen horizontal
verlaufen und in den Rahmen 5a, 5b abgestützt sind. Von den beiden Laufrädern 7
wird ein Laufrad unmittelbar durch einen Motor 7a angetrieben. Die Laufräder 7 rollen
auf den unteren Flanschteillaufflächen 8 ab. Die Rahmen 5a, 5b nehmen neben den im
Rahmen 5a, 5b jeweils mittig angeordneten Laufrädern 7 vor und hinter den
Laufrädern 7 angeordnete Horizontalführungsrollenpaare 9, 9 auf, die aus einzelnen
Führungsrollen 9 bestehen, welche vertikal drehgelagert in dem Rahmen 5a, 5b
abgestützt sind. Während die Laufräder 7 sich auf den unteren Flanschteilen 2
abstützen, liegen die Führungsrollen 9 paarweise am Steg 3 der Fahrschiene 1 an.
Aus der Fig. 1 geht hervor, daß die Rahmen 5a, 5b so weit über den jeweiligen
Flanschteil 2 des Fahrschienenquerschnitts der Fahrschiene 1 eingeschwenkt sind,
daß die Laufräder 7 sich unmittelbar in Stegnähe des Stegs 3 bewegen. Auf Höhe des
gebildeten Gelenks 10 der beiden miteinander verbundenen Rahmen 5a, 5b greift die
Last an der Achse 6 an; das unterhalb der Fahrschiene 1 gebildete Gelenk 10 ist also
zugleich Aufhängemittel für die aufzuhängende Last.Fig. 1 shows that in the upper region of the
Die Last erzeugt in den Rahmen 5a, 5b ein Schließmoment, das ein Zuschwenken der
Rahmen 5a, 5b bewirkt, durch das die Führungsrollen 9 am Steg 3 des
Fahrschienenquerschnitts eingeschwenkt gehalten werden. Die Winkelstellung
zwischen den Rahmen 5a, 5b wird in Fig. 1 durch die am Steg 3 beidseitig
anliegenden Führungsrollen 9 begrenzt; die Anlage der Führungsrollen 9 erfolgt
kraftbeaufschlagt durch die Last selbst.The load generates a closing moment in the
In Fig. 2 ist eine Draufsicht auf das Fahrwerk mit Fahrschiene gemäß Fig. 1 dargestellt.FIG. 2 is a top view of the undercarriage with the travel rail according to FIG. 1 shown.
Wie Fig. 1 zu entnehmen ist, sind am Steg 3 der dargestellten Fahrschiene 1 sich in
Längsrichtung der Schiene 1 erstreckende seitliche Führungen 11 für die
Führungsräder 9 in Form von Führungsnuten 11a ausgebildet, in denen die
Führungsräder 9 zur Erzeugung eines stabilen Fahrwerklaufs kraftbeaufschlagt geführt
sind. As can be seen in FIG. 1, the web 1 of the rail 1 shown is in
Longitudinal direction of the rail 1 extending
Fig. 3 zeigt einen vergrößerten Ausschnitt der Führungsnuten 11a zusammen mit
einem in die Führungsnuten 11a eingreifenden Führungsrad 9 mit abgerundeten
Kanten 12 im Querschnitt. Wie Fig. 3 zu entnehmen ist, ist der Querschnitt der
Führungsnuten 11a im wesentlichen trapezförmig mit zwei Schrägen 13 und einem
Trapezdach 14 ausgebildet, wobei die Rundungen der Kanten 12 der Führungsräder 9
auf den Schrägen 13 der trapezförmigen Führungsnuten 11a laufen, und zwar unter
Belassung eines Zwischenraums 15 zwischen dem mittleren Bereich des
Führungsrads 9 und dem Trapezdach 14, d.h. die Berührungsflächen zwischen
Führungsrad 9 und Führungsnut 11a sind relativ klein, was für einen verringerten
Rollwiderstand des Fahrwerks sorgt. Selbstverständlich ist es auch möglich, die Kontur
der Führungsnut 11a zur Form der in den Führungsnut 11a laufenden Führungsräder 9
zueinander nahezu komplementär auszubilden, um mit vergrößertem Aufwand die
Führungsgenauigkeit weiter zu verbessern. Dem dient auch eine Ausführungsform, bei
der die Laufrad 7 auf der einen Seite der Schiene 1 gegenüber dem Laufrad 7 auf der
anderen Seite der Schiene 1 in Fahrtrichtung zueinander versetzt angeordnet sind.Fig. 3 shows an enlarged section of the guide grooves 11a together with
a guide wheel 9 engaging in the guide grooves 11a with
Das Verhältnis aus dem vertikalen Abstand M der Achsen der Laufräder 7 und dem horizontalen Abstand L der Laufräder 7 von der Achse 6 (Schwenkachse) ist größer als 3 und kleiner als 10.The ratio of the vertical distance M of the axes of the impellers 7 and that horizontal distance L of the wheels 7 from the axis 6 (swivel axis) is greater than 3 and less than 10.
