Definitions
- the invention relates to a Einschienenunterflansch suspension for hoists with multiple wheels, which run on a rail, of which at least two seen in the direction of travel of the chassis are arranged behind one another via a common electric motor driven.
- the chassis consists essentially of a U-shaped frame and four wheels, which are movable on the lower flange of an I-shaped rail.
- the wheels each have a flange, with which the wheels are guided on the outside of the lower flange.
- the four wheels Seen in the longitudinal direction of the rail, the four wheels are divided in the manner of a four-wheel vehicle in a right pair and a left pair. Within the pairs, the two left and two right wheels are arranged at a distance and behind each other. In addition, one of the two pairs is driven by an electric motor.
- the driven pair of wheels each have a revolving sprocket, which is arranged in the region of the outer circumference of the wheel flanges of the wheels.
- the sprockets of the two driven wheels are drivingly connected to each other via an arranged between the driven wheels gear.
- This gear meshes with the two sprockets of the driven wheels and is mounted on an output shaft of a transmission that is seen in the longitudinal direction of the rail and thus seen in the direction of travel of the chassis laterally attached to the frame.
- the frame is thus between gear and gear.
- the electric motor is flanged to the transmission.
- the frame with the wheels surrounds the rail from below u-shaped and has a bolt-shaped cross-beam on which the chain hoist is suspended centrally.
- the width of the frame can be changed so that the chassis can be adjusted to the width of different I-shaped rails.
- the invention is based on the object to provide a chassis, especially Einschienenunterflansch suspension for hoists, which is wear and low noise even in dirty environment.
- the wheels Due to the direct drive of the wheels via shafts, the wheels can be formed without a revolving sprocket.
- the wheels with the sprockets of the ring gear in the Abroll Scheme of the wheels resulting in dirt due to contamination to higher wear and higher noise, especially at high speeds leads.
- the diameter of the wheels is reduced compared to wheels with sprockets, so that the wheelbase within the chassis can be chosen shorter and thus the cornering of the chassis is favored. Also, a double-wheel drive can be realized.
- a separation of the wheels from the gears is achieved in that the waves are mounted on a side plate of the chassis. This also facilitates lubrication of the gears without adversely affecting the transmission of the driving forces of the wheels to the rail by lubricant.
- one of the waves is extended beyond the gear out and is drivingly connected via a gear to the electric motor, wherein the intermediate gear takes over the power transmission to the second shaft.
- the intermediate gear is mounted on an intermediate shaft, which is drivingly connected to the electric motor.
- a translation is also provided in the form of a mounted on the intermediate shaft gear ratio, which meshes with a drivingly connected to the electric motor drive gear.
- the electric motor is mounted on the housing part. Another training provides that the electric motor over a Transmission acts on the waves.
- the landing gear consist essentially of a U-shaped frame with two driven wheels and two non-driven wheels, the frame has a right side shield and an opposite left side shield, which has a cross-beam to the U-shaped frame are mounted together on the respective inner sides of the side plates and roll on the lower flange of the rail.
- the wheels can be performed without flanges and the wheelbase be chosen smaller.
- FIG. 1 shows a sectional view of a chassis 1 for a chain hoist, not shown, or a head support of a crane.
- the chassis 1 consists essentially of a frame 2 and four wheels 3, of which a right wheel 3r and a left wheel 31 are visible.
- the frame 2 is designed substantially U-shaped and engages from below an I-shaped rail 4 in the region of the lower flange 4u and adjacent web 4s.
- the frame 2 consists of a left side plate 51 and a right Side plate 5r, on which the wheels 3r and 31 are mounted and which are connected to each other via a cross-beam 6.
- the side plates 5l and 5r central and below in each case a bore 7, through which the bolt-shaped cross-beam 6 is performed.
- the transverse traverse 7 thus connects the two side plates 5l and 5r to the frame 2.
- the cross-beam 6 is fixed in the longitudinal direction by rings 8, which rest against the respective sides of the side plates 51 and 5r.
- the side plates 51 and 5r can be adjusted to the width of the lower flange 4u of the rail 4 via the cross-beam 6 with the rings 8.
- the wheels 3 run on the top of the lower flange 4u of the I-shaped rail 4 from.
- the wheels 3 have no flanges, since the frame 2 are guided over guide rollers 9 on the lateral longitudinal sides of the lower flange 4u.
- the guide rollers 9 are for this purpose rotatably mounted about vertical axes on the side plates 5l and 5r. The vertical axes are then vertically aligned when the rail 4 is horizontal.
- FIG. 1 can be seen that only the left wheels 3l are driven by a flanged to the left side plate 5l via a gear 23 electric motor 10.
- FIG. 2 is a sectional view from above of the chassis 1 after FIG. 1 shown in a first embodiment.
- the left wheels 3l and the right wheels 3r are rotatably mounted one behind the other and at a distance from each other on the respective side plate 5l and 5r.
- the left side shield 51 and the right side shield 5r each have two hubs 11 which extend starting from the rail 4 facing inside 5i to the rail 4 and to the opposite right side shield 5r.
- On the outer circumference of the hubs 11 each have a bearing 12, preferably ball bearings, pushed, each carrying one of the wheels 3.
- the hubs 11 on the right side shield 5r are formed as full hubs, whereas the hubs 11 on the left side shield 5l are hollow hubs.
- central bores 13 are provided in the left wheels 3 l, into which shafts 14 a and 14 b are inserted.
- the shafts 14a and 14b may be held in a form-fitting manner via multi-tooth connections or press-fit connections in the bores 13.
- the bores 13 may also be provided in the right wheels 3r, but have no function there.
- the shafts 14a and 14b are mounted via a further bearing 15 in a housing part 20.
- the housing part 20 is flat against the left side shield 51 and is screwed thereto.
- a gear 16a and 16b are respectively arranged on the shafts 14a and 14b via conventional shaft and hub connection types.
- the outer diameter of the gears 16a and 16b is the same.
- an intermediate gear 17 is arranged, which meshes with the gears 16a and 16b.

- the gear formed by the gears 16a and 16b and the intermediate gear 17 is thus completed and can thus be provided with an oil or grease filling.
- the housing part 20 is formed here closed in itself and can thus be grown as a modular component to the left side plate 5l.
- the housing part 20 could also be lid-like and the left side plate 51 cup-shaped. This could be the other way around.
- first shaft 14a is extended from the left wheel 3l beyond the gear 16a and protrudes out of the housing part 20.
- the housing part 20 has a corresponding bore 24.
- the protruding end of the shaft 14 a is connected to the gear 23 with the electric motor 10, which is fixed to the outside of the housing part.

Aus dem deutschen Gebrauchsmuster
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zu Grunde, ein Fahrwerk, insbesondere Einschienenunterflansch-Fahrwerk für Hebezeuge, zu schaffen, das auch in schmutziger Umgebung verschleiß- und geräuscharm ist.Based on this prior art, the invention is based on the object to provide a chassis, especially Einschienenunterflansch suspension for hoists, which is wear and low noise even in dirty environment.
Diese Aufgabe wird durch ein Fahrwerk, insbesondere Einschienenunterflansch-Fahrwerk für Hebezeuge, mit den Merkmalen des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen des Fahrwerks sind in den Ansprüchen 2 bis 11 angegeben.This object is achieved by a chassis, in particular Einschienenunterflansch suspension for hoists, with the features of
Bei einem Einschienenunterflansch-Fahrwerk für Hebezeuge mit mehreren an einem rechten und einem linken Seitenschild gelagerten Rädern, die auf einer Schiene ablaufen, von denen mindestens zwei in Fahrtrichtung des Fahrwerkes gesehen hintereinander angeordnet über einen gemeinsamen Elektromotor antreibbar sind, wird eine Optimierung des Fahrwerkes dadurch erreicht, dass die angetriebenen Räder antriebsmäßig mit Wellen verbunden sind und die Wellen von dem Elektromotor angetrieben sind, die Wellen koaxial zur Drehachse der angetriebenen Räder ausgerichtet sind, das rechte Seitenschild und das linke Seitenschild jeweils an einer Innenseite hervorstehende Naben aufweisen, auf denen die Räder gelagert sind, die Naben für die angetriebenen Räder hohl sind, die Wellen durch die Naben und das zugehörige Seitenschild durchgeführt sind und auf den Wellen und an der den angetriebenen Rädern gegenüberliegenden Außenseite des Seitenschildes jeweils ein Zahnrad gelagert ist, die über ein Zwischenzahnrad miteinander kämmen. Hierdurch wird auch eine besonders einfache Lagerung der Räder an den Seitenschildern erreicht. Durch den Direktantrieb der Räder über Wellen können die Räder ohne einen umlaufenden Zahnkranz ausgebildet werden. Außerdem liegt bei den Rädern mit den Zahnkränzen der Zahnkranz im Abrollbereich der Räder, was in Folge von Verschmutzungen zu einem höheren Verschleiß und höheren Laufgeräuschen, insbesondere bei hohen Geschwindigkeiten, führt. Außerdem verringert sich der Durchmesser der Räder gegenüber Rädern mit Zahnkränzen, so dass der Radstand innerhalb des Fahrwerks kürzer gewählt werden kann und somit die Kurvengängigkeit des Fahrwerks begünstigt wird. Auch kann ein Doppelradantrieb realisiert werden.In a Einschienenunterflansch suspension for hoists with several mounted on a right and a left side plate wheels that run on a rail, at least two of which seen in the direction of travel of the chassis are arranged behind each other driven by a common electric motor, an optimization of the chassis is achieved in that the driven wheels are drivingly connected to shafts and the shafts are driven by the electric motor, the shafts are aligned coaxially with the axis of rotation of the driven wheels, the right side shield and the left side shield each have inner protruding hubs on which the wheels are mounted are, the hubs for the driven wheels are hollow, the waves are performed by the hubs and the associated side plate and on the shafts and on the driven wheels opposite the outside of the side plate each have a gear is mounted, the practice r an intermediate gear mesh with each other. This also makes a particularly simple storage of the wheels to the Side signs reached. Due to the direct drive of the wheels via shafts, the wheels can be formed without a revolving sprocket. In addition, in the wheels with the sprockets of the ring gear in the Abrollbereich of the wheels, resulting in dirt due to contamination to higher wear and higher noise, especially at high speeds leads. In addition, the diameter of the wheels is reduced compared to wheels with sprockets, so that the wheelbase within the chassis can be chosen shorter and thus the cornering of the chassis is favored. Also, a double-wheel drive can be realized.
Eine Trennung der Räder von den Zahnrädern wird dadurch erreicht, dass die Wellen an einem Seitenschild des Fahrwerks gelagert sind. Dies erleichtert auch eine Schmierung der Zahnräder ohne die Übertragung der Antriebskräfte der Räder auf die Schiene durch Schmiermittel negativ zu beeinflussen.A separation of the wheels from the gears is achieved in that the waves are mounted on a side plate of the chassis. This also facilitates lubrication of the gears without adversely affecting the transmission of the driving forces of the wheels to the rail by lubricant.
Konstruktiv besonders einfach ist vorgesehen, dass eine der Wellen über das Zahnrad hinaus verlängert ist und antriebsmäßig über ein Getriebe mit dem Elektromotor verbunden ist, wobei das Zwischenzahnrad die Kraftübertragung auf die zweite Welle übernimmt.Particularly simple design is provided that one of the waves is extended beyond the gear out and is drivingly connected via a gear to the electric motor, wherein the intermediate gear takes over the power transmission to the second shaft.
Alternativ ist konstruktiv besonders einfach vorgesehen, dass das Zwischenzahnrad auf einer Zwischenwelle gelagert ist, die antriebsmäßig mit dem Elektromotor verbunden ist. Bei dieser Lösung ist auch zusätzlich eine Übersetzung vorgesehen in Form eines auf der Zwischenwelle gelagerten Übersetzungszahnrades, das mit einem antriebsmäßig mit dem Elektromotor verbundenen Antriebszahnrad kämmt.Alternatively, it is particularly simple to constructively provide that the intermediate gear is mounted on an intermediate shaft, which is drivingly connected to the electric motor. In this solution, a translation is also provided in the form of a mounted on the intermediate shaft gear ratio, which meshes with a drivingly connected to the electric motor drive gear.
Durch die zuvor beschriebene Trennung der Räder von den Zahnrädern kann einfach vorgesehen werden, dass mindestens die Zahnräder und das Zwischenzahnrad von einem Gehäuseteil umschlossen sind, das an dem Seitenschild des Rahmens befestigt ist. Durch das Gehäuseteil können die Laufgeräusche der Zahnräder minimiert und einfach eine Öl- oder Fettschmierung der Zahnräder vorgesehen werden.By the above-described separation of the wheels from the gears can be easily provided that at least the gears and the intermediate gear are enclosed by a housing part which is fixed to the side plate of the frame. Through the housing part of the running noise of the gears can be minimized and easy oil or grease lubrication of the gears are provided.
In einer Ausgestaltung ist vorgesehen, dass an dem Gehäuseteil der Elektromotor gelagert ist. Eine weitere Ausbildung sieht vor, dass der Elektromotor über ein Getriebe auf die Wellen wirkt.In one embodiment, it is provided that the electric motor is mounted on the housing part. Another training provides that the electric motor over a Transmission acts on the waves.
Konstruktiv einfach ist, dass die Wellen und die angetriebenen Räder einteilig ausgebildet sind.Constructively simple is that the shafts and the driven wheels are integrally formed.
In einer Ausgestaltung wird vorgeschlagen, dass das Fahrwerk im Wesentlichen aus einem u-förmigen Rahmen mit zwei angetriebenen Rädern und zwei nicht angetriebenen Rädern besteht, der Rahmen ein rechtes Seitenschild und ein gegenüberliegendes linkes Seitenschild aufweist, die über eine Quertraverse zu dem u-förmigen Rahmen miteinander verbunden an den jeweiligen Innenseiten der Seitenschilder gelagert sind und auf dem Unterflansch der Schiene abrollen.In one embodiment, it is proposed that the landing gear consist essentially of a U-shaped frame with two driven wheels and two non-driven wheels, the frame has a right side shield and an opposite left side shield, which has a cross-beam to the U-shaped frame are mounted together on the respective inner sides of the side plates and roll on the lower flange of the rail.
Dadurch dass das Fahrwerk über seitlich an der Schiene ablaufende Führungsrollen geführt ist, können die Räder ohne Spurkränze ausgeführt werden und der Radstand kleiner gewählt werden.The fact that the chassis is guided over running laterally on the rail guide rollers, the wheels can be performed without flanges and the wheelbase be chosen smaller.

Der Rahmen 2 ist im Wesentlichen u-förmig ausgestaltet und umgreift von unten eine I-förmige Schiene 4 im Bereich deren Unterflansch 4u und angrenzenden Steg 4s. Außerdem besteht der Rahmen 2 aus einem linken Seitenschild 51 und einem rechten Seitenschild 5r, an dem die Räder 3r und 31 gelagert sind und die über eine Quertraverse 6 miteinander verbunden sind. Hierfür weisen die Seitenschilder 5l und 5r zentral und
unten jeweils eine Bohrung 7 auf, durch die die bolzenförmige Quertraverse 6 durchgeführt ist. Die Quertravese 7 verbindet somit die beiden Seitenschilder 5l und 5r zu dem Rahmen 2. Im Bereich der Bohrung 7 ist die Quertraverse 6 in deren Längsrichtung durch Ringe 8 festgelegt, die sich an den jeweiligen Seiten der Seitenschilder 51 und 5r anlegen. Über die Quertraverse 6 mit den Ringen 8 können somit die Seitenschilder 51 und 5r auf die Breite des Unterflansches 4u der Schiene 4 eingestellt werden.The

Die Führungsrollen 9 sind hierfür um vertikale Achsen drehbar an den Seitenschildern 5l und 5r gelagert.

Um die linken Räder 31 des linken Seitenschildes 51 antreiben zu können, sind in den linken Räder 3l zentralen Bohrungen 13 vorgesehen, in die Wellen 14a und 14b eingesteckt sind. Die Wellen 14a und 14b können formschlüssig über Vielzahnverbindungen oder Pressverbindungen in den Bohrungen 13 gehalten sein. Um baugleiche linke und rechte Räder 31 und 3r zu verwenden, können die Bohrungen 13 auch in den rechte Rädern 3r vorgesehen sein, haben dort aber keine Funktion.In order to be able to drive the left wheels 31 of the left side shield 51,
Die Wellen 14a und 14b sind über ein weiteres Lager 15 in einem Gehäuseteil 20 gelagert. Das Gehäuseteil 20 liegt flächig an dem linken Seitenschild 51 an und ist mit diesem verschraubt. Im Anschluss an das Lager 15 ist auf die Wellen 14a und 14b über übliche Wellen- und Nabenverbindungsarten jeweils ein Zahnrad 16a und 16b angeordnet. Der Außendurchmesser der Zahnräder 16a und 16b ist gleich. Um die Zahnräder 16a und 16b, insbesondere Stirnräder, antriebsmäßig miteinander zu verbinden, ist zwischen den Zahnrädern 16a und 16b ein Zwischenzahnrad 17 angeordnet, das mit den Zahnrädern 16a und 16b kämmt. Das Zwischenzahnrad 17 ist auf einer Zwischenwelle 18 gelagert, die parallel und in einer Linie mit den Wellen 14a und 14b angeordnet ist. Außerdem ist die Zwischenwelle 18 an beiden Enden jeweils in einem Lager 19, vorzugsweise einem Kugellager, gelagert. Die Lager 19 sind in den Wänden des Gehäuseteils 20 gelagert. Dieses Gehäuseteil 20 nimmt die Zahnräder 16a und 16b, die Wellen 14a und 14b, das Zwischenzahnrad 17 und die Zwischenwelle 18 auf. Das von den Zahnrädern 16a und 16b sowie dem Zwischenzahnrad 17 gebildete Getriebe ist somit abgeschlossen und kann somit mit einer Öl- oder Fettfüllung versehen werden.The
Das Gehäuseteil 20 ist hier in sich geschlossen ausgebildet und kann somit als modulares Bauteil an das linke Seitenschild 5l angebaut werden. Das Gehäuseteil 20 könnte auch deckelartig und das linke Seitenschild 51 topfförmig ausgebildet sein. Dies könnte auch umgekehrt sein.The
Außerdem ist die erste Welle 14a von dem linken Rad 3l über das Zahnrad 16a hinaus verlängert und ragt aus dem Gehäuseteil 20 heraus. Das Gehäuseteil 20 weist eine entsprechende Bohrung 24 auf. Das herausragende Ende der Welle 14a ist mit dem Getriebe 23 mit dem Elektromotor 10 verbunden, das an der Außenseite des Gehäuseteils befestigt ist.
