Abstract

The drive system uses an electrical generator driven by the vehicle ic engine and coupled to respective continuously variable electric motors (22) for each of the vehicle driven wheels (10). The rotor (24) of each electric motor (22) is supported by a fixed bearing (30) and a loose bearing provided by a drive spline (34) on opposite sides. The drive spline (34) uses between 2 diametrically opposing driven cogs (36, 38), in turn cooperating with an input cog (40) for the end drive. Pref the dia. of the input cog (40) is greater than that of the electric motor drive spline (34). ADVANTAGE - Improved drive efficiency.

Description

Die Erfindung betrifft einen Radantrieb für landwirt schaftliche oder industrielle Fahrzeuge, bei denen die Antriebsleistung von einer Verbrennungskraftmaschine er zeugt, in einem fahrzeugeigenen Generator in elektrische Energie umgewandelt und auf mehrere die einzelnen Räder des Fahrzeuges antreibende, stufenlos einstellbare Elek tromotoren verteilt wird. The invention relates to a wheel drive for agri cultural and industrial vehicles in which the driving power of an internal combustion engine he witnesses, converted to an onboard generator into electric power and is distributed to a plurality of the individual wheels of the vehicle driving, continuously adjustable Elek tromotoren.

Trotz mannigfaltiger Vorschläge muß das Antriebskonzept allradgetriebener Ackerschlepper als nicht hinreichend ge löst angesehen werden. Despite varied proposals the drive concept of all-wheel drive tractor as not sufficiently ge triggers must be considered. Bei einem starren Antrieb von Vor der- und Hinterachse ergeben sich bei Null-Vorlauf der Vorderachse auf dem Acker zu geringe Vortriebskräfte und mit steigendem Vorlauf von zwei und mehr Prozent auf der Straße Reifenverschleiß an den Vorderrädern, so daß der Vorderradantrieb abgeschaltet werden muß. With a rigid drive of pre DER and rear axle resulting in zero flow of the front axle is in the field to low propulsive forces and with increasing flow of two percent or more on the road tire wear on the front wheels so that the front wheel drive to be switched off. Auf diese Weise kann das Vorderachsgewicht weder für den Antrieb noch für das Bremsen genutzt werden. In this way the Front axle can be used for either the drive or for the brakes. Um diesen Nachteil zu vermei den, kann beim Bremsen der Vorderradantrieb automatisch wieder zugeschaltet werden. To vermei this disadvantage to can be automatically reconnected when braking the front wheel drive. Dies führt zum Teil zu un kontrollierten Fahrzuständen. This results in part to un controlled driving conditions.

Bei Kurvenfahrt treten die Probleme noch drastischer in Erscheinung. When cornering, the problems are even more dramatic in appearance. Mit steigendem Einschlagwinkel nimmt der ne gative Schlupf des innenlaufenden Vorderrades zu, wodurch dieses zunehmend gebremst wird und am Vortrieb des Fahr zeuges nicht teilnimmt. With increasing turning angle of the ne gative slip of the inside front wheel speed increases, making this increasingly slowed down and die not participating in the propulsion of the drive. Bei Kurvenfahrt äußert sich das darin, daß der Wendekreis trotz Antrieb größer und nicht kleiner wird. When cornering, this manifests itself in the fact that the turning circle becomes larger and not smaller despite drive. Auf der Straße führt dies zu zusätzlichem Reifenverschleiß und im Feld zum Abscheeren der Grasnarbe. On the road leading to additional tire wear and in the field for Abscheeren the turf. Besonders die engen Kurven am Vorgewende bereiten Prob leme. Especially the tight turns on headlands prepare prob lems.

Lösungsansätze zur Behebung dieses Problems sind: zusätz liche Übersetzungsstufen im Antriebsstrang zur Vorder achse, Abschalten des äußeren Vorderrades wie z. Approaches to correct this problem are: zusätz Liche translation step axle in the drive train to the front, turning off the outside front wheel such. B. beim NO-Spin-Differential, der permanente Allradantrieb mit Längsdifferential etc. Die Nachteile sind offensichtlich: Getriebesprünge, Abschalten eines Antriebsrades, unkon trollierte Umschaltung von Ziehen auf Bremsen, nur Antrieb über drei der vier Räder des Schleppers etc. Zunehmend be reitet auch die Abstützung des Vorderachsmomentes auf dem Boden Probleme. B. when NO-spin differential, permanent four-wheel drive with a longitudinal differential, etc. The drawbacks are obvious: transmission jumps, switching off a drive wheel, unkon trolled switching from pulling on brakes, drive only three of the four wheels of the tractor etc. Increasingly be also rides the support of the Vorderachsmomentes on the ground problems.

Mit den Vorschlägen der EP 01 11 037 B1 und der EP 01 17 945 B1 wurde der Versuch unternommen, die heute noch unterschiedlichen Antriebskonzepte für Vorderachse (außen liegender Planetentrieb) und Hinterachse (innenliegender Planetentrieb) zu standardisieren und zu einer Familie von außenliegenden Antrieben für gelenkte und ungelenkte Achsen zusammenzufassen. With the proposals of EP 01 11 037 B1 and EP 01 17 945 B1, the experiment was made that still different drive concepts for the front axle (outboard planetary final drive) and rear axle (internal planetary drive) to standardize and to a family of external drives for steered summarize and unsteered axles. Bei den ungleichen Raddurch messern an Vorder- und Hinterachsen bei Standardschleppern ergibt sich ein Konzept, daß die Hinterräder der nächst kleineren Schlepperfamilie als Vorderräder der größeren Schlepperreihe eingesetzt werden können. In the case of unequal Raddurch diameters on the front and rear axles standard tractors, a concept that the rear wheels of the next smaller tractor family can be used as the front wheels of the tractor larger number results. Bei den genannten Vorschlägen ergaben sich hierbei im Prinzip zentrale Ein zelradantriebe, daß heißt, der Antrieb geht durch die Achsbrücke. In the mentioned proposals, central A were here zelradantriebe in principle, that is, the drive goes through the axle housing. Dieses schränkt die Bodenfreiheit und die Möglichkeiten in der Ausgestaltung der Achse ein. This limits the ground clearance and the possibilities in the design of the axle. Darüber hinaus wurden die Mehrzahl der oben beschriebenen Probleme keiner Lösung zugeführt. In addition, the majority of the problems described above were remains unresolved.

Während die EP 01 13 490 B1 und die EP 01 12 421 B1 Längs differentiale beschreiben, welche das Motormoment in einem vorgegebenen Verhältnis auf die Vorderachse und Hinter achse aufteilen und als permanente Antriebe fast alle An triebsprobleme der Vorderachse lösen, beschreiben die DE 35 43 871 C1 und die EP 02 28 617 B1 erste Versuche, die Differentialwirkung in die Radantriebe zu verlegen, das heißt ohne Längs- und Querdifferentiale auszukommen. While the EP 01 13 490 B1 and EP differential describe 01 12 421 B1 longitudinal, which divide the engine torque in a predetermined ratio to the front axle and rear axle and as a permanent drive nearly all to operational problems to solve the front axle, the DE describe 35 43 871 C1 and EP 02 28 617 B1 the first attempts to route the differential action in the wheel drives, that is, without getting along longitudinal and transverse differentials. Diese Überlegungen zeigten noch nicht den gewünschten Er folg. These considerations showed not the desired He successfully.

Während der permanente mechanische Frontantrieb mit Längs differential heute als der bestmögliche Allradantrieb an gesehen werden kann, ist es das Ziel der vorliegenden Er findung, eine Lösung anzugeben, die in technischer Hin sicht keine Fragen mehr offen läßt und die dargestellten Probleme überwindet. During the permanent mechanical front wheel drive with longitudinal differential can be seen as the best all-wheel drive today, it is the object of the present invention to provide a solution that view in technical Hin leaves no question unanswered and overcomes the problems outlined.

Hierzu wird der Antrieb des Ackerschleppers in Einzelrad antriebe aufgelöst, welche die in der EP 01 11 037 B1 und der EP 01 17 945 B1 beschriebenen Konzepte befolgen. For this purpose, the drive of the tractor is dissolved in individual wheel drives which follow the concepts described in EP 01 11 037 B1 and EP 01 17 945 B1. Jeder Radantrieb enthält, wie es im Zusammenhang mit Lastzügen schon aus der DE-OS 22 41 878 hervorgeht, einen Elektro motor. Each contains Wheel Drive, as can be seen in the context of road trains already known from DE-OS 22 41 878, an electric motor. Die Energie für den Elektromotor wird von einer fahrzeugeigenen Verbrennungskraftmaschine und einem nach geschalteten Generator bereitgestellt. The energy for the electric motor of a vehicle's internal combustion engine and provided by a connected generator.

Die mit der Erfindung zu lösende Aufgabe wird darin ge sehen, einen Radantrieb der eingangs genannten Art anzu geben, der auch für landwirtschaftliche und industrielle Fahrzeuge nutzbar ist, bei dem der Rotor des Elektromotors frei von Radialkräften ist, die von dem Antriebsritzel ausgehen, und bei dem die Motorbaulänge möglichst klein gehalten wird. The object to be met with the invention is therein seen ge give to a wheel drive of the type mentioned, which can also be used for agricultural and industrial vehicles, in which the rotor of the electric motor is free of radial forces emanating from the drive pinion, and which the motor frame is kept as small as possible.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Rotor des Elektromotors in einem Festlager und in einem Loslager gelagert ist, wobei das Loslager durch ein An triebsritzel gebildet wird, welches zwischen zwei sich diametral gegenüberliegenden Abtriebsrädern angeordnet ist und diese antreibt, und wobei die Abtriebsräder ihrerseits mit einem gemeinsamen Eingangsrad für den Endantrieb in Eingriff stehen. The object is inventively achieved in that the rotor of the electric motor is mounted in a fixed bearing and in a movable bearing, wherein the floating bearing is formed drive pinion by An, which is arranged between two diametrically opposed driven gears and drives this, and wherein the driven gears in turn are connected to a common input gear for the driveline is engaged. Der Rotor wird durch das Festlager in axialer Richtung fixiert und auf der anderen Seite zwi schen den Abtriebsrädern geführt. The rotor is fixed by the fixed bearing in the axial direction and Zvi on the other hand rule out the output gears.

Der erfindungsgemäße Radantrieb hat eine vergleichsweise geringe Baulänge, da gegenüber konventionellen Elektro motoren ein Pestlager eingespart wird. The wheel drive according to the invention has a comparatively small overall length, as compared to conventional electric motors, a Pestlager is saved. Ferner ergibt sich ein von Radialkräften freier Antrieb, was bei den ge wünschten hohen Drehzahlen zu einer Wirkungsgradverbes serung führt. Furthermore, there is a free radial forces drive, resulting in the desired ge high speeds to a Wirkungsgradverbes provement.

Der Antrieb läßt sich vollständig von der Radaufhängung (z. B. Lenkachse) trennen. The drive can be completely from the wheel suspension (z. B. steering axis) separate. Hierdurch eröffnen sich Frei heiten, die Achse als Hoch-, Standard- oder Niedrigachse auszuführen, wobei immer ein gleichartiger Radantrieb ein setzbar ist (Modulbauweise). In this way, free open units to perform the axis as high, standard or low-axis, always a similar Wheel a settable is (modular). Bis auf die unterschiedlichen Achsanschlüsse werden grundsätzlich keine zusätzlichen Teile notwendig und zwar unabhängig davon, ob es sich um eine Lenkachse oder eine ungelenkte Achse handelt. Except for the different Achsanschlüsse basically no additional parts are necessary regardless of whether there is a steering axle or unguided axle.

Vorzugsweise ist der Radantrieb so ausgelegt, daß der Elektromotor und/oder die Radaufhängung außerhalb der Rad achse an das Endantriebsgehäuse anflanschbar sind. Preferably, the wheel is designed so that the electric motor and / or the suspension outside the wheel axis to the final drive are flange-mounted.

Bei dem erfindungsgemäßen Radantrieb findet zweckmäßiger weise ein Elektromotor Anwendung, welcher von der Drehzahl Null bis zur Maximaldrehzahl stufenlos verstellt werden kann. In the inventive wheel drive is advantageously an electric motor as application, which can be continuously adjusted to the maximum speed of the speed zero. In Abhängigkeit von der gewünschten Geschwindigkeit und dem gewünschten Lenkradius berechnet ein Computer die erforderliche Drehzahl für jede Antriebseinheit, stellt diese ein und kontrolliert sie. Depending on the desired speed and the desired steering radius, a computer calculates the required speed for each drive unit, provides these and controls them. Besonders geeignet ist die Verwendung eines Asynchronmotors. Particularly suitable is the use of an asynchronous motor.

Da die Elektromotoren in Vorwärts- und Rückwärtsrichtung in gleicher Weise antreiben und bremsen können, ergeben sich bei dem Einzelradantriebskonzept weder bevorzugte Fahrtrichtungen noch (bei geeigneter Ansteuerung der Elektromotoren) Verspannungen zwischen den Rädern hin sichtlich Drehen auf der Stelle, Rundgang, Einzelradlen kung oder normalem Lenkeinschlag. may since the electric motors in forward and reverse directions to drive in the same manner and brakes, resulting in the Einzelradantriebskonzept neither preferred directions still (with suitable control of the electric motors) tension between the wheels toward clearly turning on the spot, guided, Einzelradlen kung or normal steering angle , Bis auf Stromkabel und Steuerleitungen beeinträchtigt nichts die modulare und funktionsgerechte Anordnung aller Komponenten, ob gefe derte oder ungefederte Achse, Schmal-, Normal- oder Weit spur-Schlepper, Hochrad-, Standard- oder Niedrig-Schlepper etc. Keine Antriebswellen oder Kardanantriebe behindern die Gestaltungsfreiheit. Except for power cables and control lines not affected the modular and functional arrangement of all components, whether Gefe-made or unsprung axle, narrow, normal or wide-track tractors, Hochrad-, standard or low-tractor hinder etc. No drive shafts or the gimbals design freedom.

Die fliegende Lagerung einer Antriebswelle, deren Ein gangsrad zwischen zwei Zwischenrädern gelagert ist, ist zwar durch die DE 36 40 947 A1 bekannt geworden, hierbei handelt es sich jedoch um eine Antriebswelle, die über ein Universalgelenk mit einem Differentialgetriebe in Ver bindung steht. The cantilever support of a drive shaft which A is mounted gangsrad between two intermediate wheels is indeed become known from DE 36 40 947 A1, but in this case there is a drive shaft which is connected via a universal joint with a differential gear, in conjunction. Probleme, die bei modularem Einzelradan trieb und in Verbindung mit einem Elektromotor auftreten, werden nicht angesprochen. Problems that drove in modular Einzelradan and occur in connection with an electric motor, are not addressed.

Vorzugsweise bilden Elektromotor und Antriebsritzel eine Einheit und werden von außen an ein Getriebegehäuse, das den Endantrieb aufnimmt, angeflanscht. Preferably, the electric motor and drive gear form one unit and are flanged to the outside of a gearbox housing accommodating the driveline. Das Endantriebs getriebe kann zweckmäßigerweiser wahlweise aus einer einstufigen Stirnradstufe oder einer Stirnradstufe mit einer nachgeschalteten Planetenradstufe bestehen. The final drive gear may conveniently wise optionally consist of a one-stage spur gear or a spur gear stage with a downstream planetary gear stage. Dies ermöglicht eine hinreichende Untersetzung der relativ hohen Motordrehzahl. This allows a sufficient reduction of the relatively high engine speed.

Um eine zuverlässige Abdichtung des Elektromotors gegen über dem Naßraum des Endantriebes, in dessen Gehäuse sich flüssiges Schmiermittel befindet, zu gewährleisten, ist es von Vorteil, die Antriebswelle des Elektromotors gegenüber dem Endantriebsgehäuse durch eine Dichtung abzudichten. To provide a reliable sealing of the electric motor compared to the wet space of the final drive, is liquid lubricant is in the housing to ensure it is advantageous to seal the drive shaft of the electric motor with respect to the final drive housing by a seal.

Weitere vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung gehen aus den Unteransprüchen hervor. Further advantageous embodiments and developments of the invention will become apparent from the dependent claims.

As apparent from Fig. 2, is the drive pinion 34 having a spur gear of the final drive in engagement. Es greift in die Verzahnung zweier sich diametral gegenüber stehender Abtriebsräder 36 , 38 ein, die ihrerseits mit einem Eingangsrad 40 des Endantriebes in Eingriff stehen. It engages in the teeth of two diametrically opposed driven gears 36, 38, which are in turn connected to an input gear 40 of the final drive in engagement. Durch diesen Zahneingriff ist das Antriebsritzel 34 in radialer Richtung festgelegt. By this meshing, the pinion is fixed in the radial direction 34th Es kann weder seitlich noch in vertikaler Richtung ausbrechen. It can not even break out in the vertical direction to the side.

Das Eingangsrad 40 steht gemäß Fig. 1 über eine konzen trisch zur Radachse 12 angeordnete Hülse 42 mit einem Sonnenrad 44 eines Planetengetriebes in Verbindung. The input gear 40 is shown in FIG. 1 via a concentrated symmetrical to the wheel axle 12 arranged sleeve 42 having a sun gear 44 of a planetary transmission in conjunction. Das Sonnenrad 44 treibt mehrere auf einem Planetenradträger 46 angeordnete Planetenräder 48 an, die auf einem gehäuse festen Hohlrad 50 abrollen. The sun gear 44 drives planet carrier 46 on a plurality of arranged planetary gears 48, which roll on a housing-fixed ring gear 50th Der Planetenradträger 46 ist drehfest auf der Radachse 12 montiert und überträgt das Drehmoment auf das Rad 10 . The planet carrier 46 is rotatably mounted on the axle 12 and transmits the torque to the wheel 10th
