Description
Triebwerk für allradangetriebenen Schlepper Die Erfindung betrifft ein Triebwerk für ein allradangetriebenes Fahrzeug, z.B. einen Schlepper, dessen einer Achsantrieb, z.B. der Vorderachsantrieb abschaltbar ist.Engine for all-wheel drive tractor The invention relates to an engine for a four-wheel drive vehicle, e.g. a tractor, whose an axle drive, e.g. the front axle drive, can be switched off.
Aus Preisgründen wurden allradangetriebene Schlepper ohne Längsdifferential ausgeführt. Im Betrieb treten hierdurch besonders bei Kurvenfahrt Verspannungen in den Triebwerksteilen zwischen den beiden Achsen auf. Zur Abh@@fe wurde eine Überlastkupplung verwendet.For price reasons, all-wheel-drive tractors were used without a longitudinal differential executed. This creates tension during operation, especially when cornering in the engine parts between the two axles. An overload clutch was used to prevent this used.
Zum Schalten des Vorderachsantriebes dient eine Klauenkupplung. Nachteil dieser Kupplung ist, daß der Varderacheantrieb nur nach vorheriger Betätigung der Fahrkupplung eingeschaltet werden kann.A dog clutch is used to switch the front axle drive. disadvantage This clutch is that the Varderacheantantrieb only after prior actuation of the Driving clutch can be switched on.
Wegen der vorerwähnten Verspannungen wurde eine Vorrichtung zum indirekten Abschalten des Vorderradantriebes entwickelt, Die Abschaltung erfolgt dabei durch eine beim Einschalten vorgespannte Feder, deren Spannung beim Abschalten zunächst nur freigegeben wird und erst abschaltet, wenn die Kupplungsteile sich durch den Betrieb gelockert haben. Nachteil der formschlüssigen Schaltung ist, daß der Vorderradantrieb während des Fahrbetriebes nicht eingeschaltet werden kann, ohne die Fahrkupplung auszuschalten.Because of the aforementioned tension, a device for indirect Shutdown of the front-wheel drive developed, the shutdown is done by a spring pretensioned when switching on, its tension when switching off first is only released and only switches off when the coupling parts are through the Have loosened operations. The disadvantage of the positive circuit is that the front wheel drive cannot be switched on while driving without the drive clutch turn off.
Die Nachteile der bekannten Schaltvorrichtungen werden durch die Erfindung beseitigt. Die Erfindung besteht darin, daß in einem allradangetriebenen Schlepper zum Abschalten des einen Antriebes eine Lamellenkupplung vorgesehen isst. Mit dieser Kupplung kann beispielsweise der Vorderradantrieb unabhängig von dem jeweiligen Fahrzustand zu- oder abgeschaltet werden.The disadvantages of the known switching devices are alleviated by the invention eliminated. The invention consists in that in an all-wheel drive tractor A multi-disc clutch is provided to switch off one drive. With this Coupling, for example, the front-wheel drive can be independent of the respective Driving state can be switched on or off.
Nach der Erfindung ist ferner die Lamellenkupplung für ein bestimmtes übertragbares Dreh@oment ausgelegt, so daß sie gleichzeitig die @unktion der Überlastkupplung übernimmt. Der Bauaufwand ist also geringer als der der bekannten Ausführungen mit formschlüssiger Schaltung und getrennter Überlastkupplung.According to the invention, the multi-plate clutch is also for a certain transmittable torque designed so that it also functions as the overload clutch takes over. The construction effort is therefore less than that of the known versions positive circuit and separate overload clutch.
Um einen bestimmten Drehzahlunterschied beider Achsen aufzunehmen, besitzt die Lamellenkupplung in Ö@ laufende Lamellen mit Sinterbelag, so daß der entstehende Schlupf keine unzulässige Erwärmung hervorruft. .In order to record a certain speed difference between the two axes, the multi-disc clutch has in Ö @ running discs with sintered lining, so that the the resulting slip does not cause any inadmissible heating. .
Die Zeichnung zeigt schematisch ein Ausführungsbeispiel eines Allradantriebes nach der Erfindung. Das Eingang@ritzel l des Allradtriebwerke kämmt mit einem Zahnrad 2, welches das Kegelrit@el 3 des Differentials 4 der Hinterräder 5 und 6 über Untersetzungsgetriebe , 7 und 8 antreibt.The drawing shows schematically an embodiment of an all-wheel drive according to the invention. The input @ pinion l of the all-wheel drive meshes with a gear 2, which the Kegelrit @ el 3 of the differential 4 of the rear wheels 5 and 6 via reduction gears, 7 and 8 drives.
Das Zahnrad 2 kämmt mit dem Zahnrad 9, welches mit dem Zahnrad 10 fest verbunden ist. Das Zahnrad 10 kämmt mit einem größeren Zahnrad 11. Dieses ist mit den Kupplungslamellen 12 verbunden. Die daneben angeordneten Lamellen 13 sind mit einem Ritsel 14 verbunden, welches mit dem Zahnrad 15 im Eingriff ist. Dieses treibt eine Gelenkwelle 16 an, welche mit einem Kegelritzel 17 verbunden ist. Dieses treibt das Differential 18 zwischen den Vorderrädern 19 und 20 an.The gear 2 meshes with the gear 9, which meshes with the gear 10 is firmly connected. The gear 10 meshes with a larger gear 11. This is connected to the clutch plates 12. The lamellas 13 arranged next to it are connected to a pinion 14 which is in engagement with the gear 15. This drives a cardan shaft 16 which is connected to a bevel pinion 17. This drives the differential 18 between the front wheels 19 and 20.
Die Lamellen 12 und 13 werden durch eine Kupplungsmuffe 21 aneinander gepresst. Dadurch wird der Vorderradantrieb eingeschaltet. Die Kupplung 12/13 hat geringe Schaltarbeit zu leisten, da die Zahnräder 11 und 14 beim Einschal-ten der Kupplung bis auf einen gewiesen Vor- oder Nachlauf stets synchron laufen. Die infolge des Schlupfes erzeugte Wärme wird durch die Lamellen an das umgebende Ö1 abgeführt.The lamellae 12 and 13 are pressed against one another by a coupling sleeve 21. This engages the front-wheel drive. The clutch 12/13 has to perform little switching work, since the gears 11 and 14 always run synchronously when the clutch is switched on, apart from a certain lead or lag. The heat generated as a result of the slip is dissipated through the fins to the surrounding oil .
Die Lamellen können mit einem Sinterbelag versehen sein; The lamellae can be provided with a sintered coating;
