Description

BESCHREIBUNG  DESCRIPTION
Gleiskettenspanner für ein Gleiskettenfahrzeug Caterpillar tensioner for a caterpillar
Die Erfindung beschäftigt sich mit einem Gleiskettenspanner von frontangetriebenen Gleiskettenfahrzeugen, insbesondere mit einem elektrischen Kettenspanner. The invention relates to a track tensioner of front-driven caterpillar vehicles, in particular with an electric chain tensioner.
Eine Einstellvorrichtung für die Spannrollen der Gleisketten von Fahrzeugen offenbart die DE 575 646 C. Eine weitere Gleiskettenspanneinrichtung beschreibt die DE 1 139 759 C. DE 575 646 C discloses an adjusting device for the tension rollers of the caterpillars of vehicles. A further track tensioning device is described in DE 1 139 759 C.
Die Vorrichtung zum Spannen von Gleisketten an Kettenfahrzeugen nach der DE 27 22 457 C2 zeichnet sich dadurch aus, dass ein Lagerbolzen mehrere seitliche Flächen oder an der Stirnseite ein oder mehrere Ausnehmungen für einen Spannschiüssel besitzt, d.h., derartige Ketten werden durch einen mechanischen, starr eingestellten Kettenspanner gespannt. Nachteilig ist, dass dieser Kettenspanner die aktuellen Zustände nicht berücksichtigt bzw. auch nicht auf diese reagieren kann. The device for tensioning crawler tracks on tracked vehicles according to DE 27 22 457 C2 is characterized in that a bearing pin has a plurality of lateral surfaces or on the front side one or more recesses for a cocking key, ie, such chains are set by a mechanical, rigid Chain tensioner cocked. The disadvantage is that this chain tensioner does not take into account the current conditions or can not respond to them.
Eine elastische Kettenspannvorrichtung benennt die DE 696 12 616 T2 (EP 0 832 027 B1 ), die auf die US 2 315 214 A aufbauend das Problem löst, dass das Gleiskettenfahrzeug schneller und mit verbessertem Komfort sowohl über raue Geländeoberflächen als auch auf Straßenoberflächen fährt. Dazu ist der Vorspannarm von einem Pendelarm getrennt und wesentlich kürzer als der Pendelarm selbst. An elastic chain tensioning device is described in DE 696 12 616 T2 (EP 0 832 027 B1) which, based on US Pat. No. 2 315 214 A, solves the problem that the caterpillar vehicle travels both over rough terrain surfaces and on road surfaces faster and with improved comfort. For this purpose, the biasing arm is separated from a pendulum arm and much shorter than the pendulum itself.
Eine hydraulische Vorrichtung zum Spannen von Ketten, Riemen, Endlosbändern etc. offenbart die DE 694 01 335 T2 (EP 0 657 343 B1). A hydraulic device for tensioning chains, belts, endless belts, etc. is disclosed in DE 694 01 335 T2 (EP 0 657 343 B1).
Aus der DE 20 2007 015 270 U1 bzw. EP 2 060 476 A1 ist eine Laufwerksmodifikation bekannt, die die Nachrüstung bzw. Umrüstung eines Gleiskettenfahrzeuges mit einer anderen Gleiskette vorschlägt. Dazu werden auch Hydropfedern nachgerüstet. Durch deren Einsatz wird aufgrund der größeren Federwege jedoch die Neigung zur Kettenbauchbiidung zwischen Triebrad und erstem Laufrad erhöht. Eine derartige Kettenbauchbiidung ist aber unerwünscht. Daher wird angeregt, die Kettenspannung zu optimieren durch eine vom Fahrerplatz aus bedienbare Versteileinrichtung. Bei kaltem Laufwerk wird die Kettenspannung erhöht und beim warmen Laufwerk reduziert. Angaben zu der Versteileinrichtung selbst werden nicht gemacht. From DE 20 2007 015 270 U1 or EP 2 060 476 A1 a drive modification is known which proposes the retrofitting or conversion of a caterpillar vehicle with another track. For this purpose also Hydropfedern be retrofitted. Through their use However, the tendency to Kettenbauchbiidung between the drive wheel and the first impeller is increased due to the larger spring travel. However, such a chain belly training is undesirable. Therefore, it is suggested to optimize the chain tension by an operating device that can be operated from the driver's seat. With a cold drive, the chain tension is increased and reduced with the warm drive. Details of the adjusting device itself are not made.
Hier sieht die Erfindung vor, anstelle eines mechanischen, starr eingestellten Kettenspanners etc. einen elektrischen Kettenspanner vorzusehen. Dieser kann in einer bevorzugten Weiterbildung beispielsweise vom Fahrersitz aus betrieben werden. Der elektrische Kettenspanner kann dauerhaft am Bordnetz angeschlossen sein. Here, the invention provides, instead of a mechanical, rigidly adjusted chain tensioner, etc. to provide an electric chain tensioner. This can be operated in a preferred embodiment, for example, from the driver's seat. The electric chain tensioner can be permanently connected to the vehicle electrical system.
Anhand eines Ausführungsbeispiels mit Zeichnung soll die Erfindung näher erläutert werden. Es zeigt die einzige Figur eines frontgetriebenen Kettenfahrzeuges 1 mit einer Gleiskette 5, einem in diesem Ausführungsbeispiel sieben Laufrollen aufweisenden Rollenlaufwerk 6, einem Treib- oder Antriebsrad 7 sowie einem Führungsrad 8. Mit 3 sind Hydropfedern gekennzeichnet, über die die Laufräder 9 des Rollenlaufwerkes am Chassis des Gleiskettenfahrzeuges angebunden sind. Reference to an embodiment with drawing, the invention will be explained in more detail. It shows the only figure of a front-wheeled tracked vehicle 1 with a track 5, in this embodiment, seven rollers having roller drive 6, a drive or drive wheel 7 and a guide wheel 8. 3 are hydraulic springs characterized by the wheels 9 of the roller drive on the chassis of the caterpillar are tethered.
Leicht angedeutet ist eine Gleiskettenbauchbildung 2 zwischen dem Treibrad 7 sowie der ersten Laufrolle 9. Zur Vermeidung einer derartigen Kettenbauchbiidung 2 ist nunmehr vorgesehen, einen elektrischen Kettenspanner 4 einzubinden. Der elektrische Kettenspanner 4 ist bevorzugt vor dem Führungsrad 8 (in Fahrtrichtung gesehen) in der Nähe des Führungsrades 8 und damit zwischen dem Antriebsrad 7 und dem Führungsrad 8 eingebunden. Dieser Kettenspanner 4 ist bevorzugt vom Inneren des Fahrzeuges 1 fembedienbar, beispielsweise vom Fahrerplatz aus. Slightly indicated is a crawler belt formation 2 between the drive wheel 7 and the first pulley 9. To avoid such a chain belly training 2, it is now provided to incorporate an electric chain tensioner 4. The electric chain tensioner 4 is preferably in front of the guide wheel 8 (seen in the direction of travel) in the vicinity of the guide wheel 8 and thus involved between the drive wheel 7 and the guide wheel 8. This chain tensioner 4 is preferably fembedienbar from the interior of the vehicle 1, for example, from the driver's seat.
Der elektrische Kettenspanner 4 wird durch einen sogenannten Eiektro-Versteiler gebildet. Diese Art Versteller finden im Bergbau und auch bei der Bahn Anwendung und werden beispielsweise durch die Firma Rahmann hergesteilt und vertrieben. Derartige Eiektro-Versteiler umfassen neben einer Bremse zumindest einen Rückmeldeschalter und eine Stellungsrückmeldung. Die Verstellung erfolgt durch eine Schubstange des Elektro-Verstellers. Vorteilhaft ist zudem, wenn der Eiektro-Versteiler einen Lastschalter und einen Verdrehschutz aufweist. Dadurch wird die Arbeitsfähigkeit des Kettenspanners 4 gewährleistet- Ein weiterer Vorteil derartiger Elektro-Versteller liegt darin, dass sie abgestimmt auf besondere Aufgabenstellungen und Piatzverhäitnisse im Handel angeboten werden, sodass eine kostengünstige Umrüstung auf einen elektrischen Kettenspanner möglich ist. Als Antrieb derartiger Elektro- Verstelier sind Servomotore, Schrittmotore, Positionierantriebe als auch Linearantriebe einsetzbar. The electric chain tensioner 4 is formed by a so-called Eiektro-divider. These type adjusters are used in mining and also in the railway application and are for example manufactured and sold by the company Rahmann. Such Eiektro-divider include in addition to a brake at least one feedback switch and a position feedback. The adjustment is made by a push rod of the electric adjuster. It is also advantageous if the Eiektro-divider has a load switch and a twist. This ensures the working capacity of the chain tensioner 4 - Another advantage Such electric adjuster is that they are matched to specific tasks and Piatzverhit to be offered in the trade, so that a cost-effective conversion to an electric chain tensioner is possible. As a drive of such electric Verstelier servo motors, stepper motors, positioning drives and linear drives can be used.
