Mit der Hubarm-Achse 4 ist ein teilverzahntes Zahnrad 30 verbunden, das sich bei einer Drehung des Antriebszahnrads 29 mitdreht. Das Zahnrad 30 greift in ein Zahnrad 31 der elektronischen Winkelerfassung 21 ein, die einen weiteren Sensor in einem weiteren Sensorgehäuse 32 umfaßt. Der weitere Sensor gibt die erfaßte Winkelstellung an die Auswerteelektronik weiter (in der Zeichnung nicht dargestellt).With the Hubarm-axis 4, a partially toothed gear 30 is connected, which rotates with a rotation of the drive gear 29. The gear 30 engages a gear 31 of the electronic angle detection 21, which includes a further sensor in a further sensor housing 32. The further sensor outputs the detected angular position to the transmitter (not shown in the drawing).

Der Antrieb für die Kippmulde 2 umfaßt ferner eine erste Umlenkstange 33, die an dem Antriebszahnrad 29 und an einem ersten Umlenkhebel 34 gelenkig befestigt ist. Der erste Umlenkhebel 34 umfaßt eine Hebelstange 35, an der ein Hebelarm 36 vorgesehen ist. Die Hebelstange 35 ist in Aufnahmen 37 (Fig. 2) drehbar gelagert, die an den Verbindungsstellen der Schenkel 7 und 8 des Hubarms 1 vorgesehen sind. Die erste Umlenkstange 33 ist an dem Hebelarm 36 gelenkig befestigt.The drive for the dump body 2 further comprises a first deflecting rod 33 which is hinged to the drive gear 29 and to a first lever 34. The first lever 34 comprises a lever rod 35, on which a lever arm 36 is provided. The lever rod 35 is in receptacles 37 ( Fig. 2 ) are rotatably mounted, which are provided at the connection points of the legs 7 and 8 of the lifting arm 1. The first deflecting rod 33 is hinged to the lever arm 36.

Der Antrieb für die Kippmulde 2 umfaßt ferner eine zweite Umlenkstange 38, die an dem ersten Umlenkhebel 34 und an einem zweiten Umlenkhebel 39 gelenkig befestigt ist. Der zweite Umlenkhebel 39 umfaßt eine Hebelstange 40, an der ein Hebelarm 41 vorgesehen ist. Die Hebelstange 40 ist in Aufnahmen 42 (Fig. 2) drehbar gelagert, die an den Enden der zweiten Schenkel 8 des Hubarms 1 vorgesehen sind. Die Aufnahmen 42 liegen am Fuß der Verlängerungen 10. Die zweite Umlenkstange 38 ist an dem Hebelarm 36 des ersten Umlenkhebels 34 gelenkig befestigt.The drive for the dump body 2 further comprises a second deflection bar 38, which is hinged to the first lever 34 and a second lever 39. The second reversing lever 39 comprises a lever rod 40, on which a lever arm 41 is provided. The lever rod 40 is in receptacles 42 ( Fig. 2 ), which are provided at the ends of the second leg 8 of the lifting arm 1. The receptacles 42 are located at the foot of the extensions 10. The second deflecting rod 38 is pivotally attached to the lever arm 36 of the first reversing lever 34.

Der Antrieb für die Kippmulde 2 umfaßt schließlich einen Kipphebel 43, der an der Kippmulde 2 gelenkig befestigt ist. Das andere Ende des Kipphebels 43 ist an dem Hebelarm 41 des zweiten Umlenkhebels 39 gelenkig befestigt. Die Befestigungsstelle des Kipphebels 43 an dem Hebelarm 41 ist mit der Befestigungsstelle der zweiten Umlenkstange 38 an dem Hebelarm 41 koaxial.The drive for the dump body 2 finally includes a rocker arm 43 which is hinged to the dump body 2. The other end of the rocker arm 43 is hinged to the lever arm 41 of the second reversing lever 39. The attachment point of the rocker arm 43 on the lever arm 41 is coaxial with the attachment point of the second deflection bar 38 on the lever arm 41.

Die Antriebsmotoren 12 und 23 sind unabhängig voneinander betätigbar. Sie sind ferner derart betätigbar, daß die Antriebszahnräder 18, 29 synchron zueinander betätigt werden. Die Antriebsmotoren 12, 23 können synchron gesteuert werden, um auf diese Weise die Antriebszahnräder 18, 29 synchron miteinander zu betätigen. Stattdessen oder zusätzlich kann die Synchronität der Bewegungen der Antriebszahnräder 18, 29 durch die elektronische Winkelerfassung 21 unterstützt oder hergestellt werden.The drive motors 12 and 23 are independently operable. They are also actuated such that the drive gears 18, 29 are operated synchronously with each other. The drive motors 12, 23 can be synchronously controlled to thereby drive the drive gears 18, 29 in synchronism with each other. Instead or in addition, the synchronicity of the movements of the drive gears 18, 29 can be assisted or established by the electronic angle detection 21.

Wenn die Antriebszahnräder 18, 29 synchron bewegt werden, wird der Hubarm 1 durch die Bewegung des Antriebszahnrads 18 bewegt und wird durch die synchrone Bewegung des Antriebszahnrads 29 bewirkt, daß die Kippmulde 2 ihre Winkelstellung gegenüber dem Hubarm 1 nicht oder nur unwesentlich verändert. Dies ist in Fig. 4 gezeigt. Zunächst befindet sich der Hubarm 1 in seiner unteren Endstellung gemäß Fig. 4a. Durch eine Bewegung des Antriebszahnrads 18 kann er in eine Mittelstellung gemäß Fig. 4b angehoben werden. Während dieser Bewegung wird das Antriebszahnrad 29 synchron zum Antriebszahnrad 18 bewegt. Dies bewirkt, daß die Kippmulde 2 ihre relative Stellung gegenüber dem Hubarm 1 im wesentlichen beibehält.When the drive gears 18, 29 are moved synchronously, the lift arm 1 is moved by the movement of the drive gear 18 and is caused by the synchronous movement of the drive gear 29 that the dump body 2 does not change its angular position relative to the lift arm 1 or only insignificantly. This is in Fig. 4 shown. First, the lift arm 1 is in its lower end position according to Fig. 4a , By a movement of the drive gear 18, it can in accordance with a middle position Fig. 4b be raised. During this movement, the drive gear 29 is moved synchronously with the drive gear 18. This causes the dump body 2 to maintain its relative position relative to the lift arm 1 substantially.

Durch eine weitere Bewegung des Antriebszahnrads 18 wird der Hubarm in die in Fig. 4c gezeigte, obere Endstellung bewegt. Währenddessen bewegt sich das Antriebszahnrad 29 synchron mit, so daß die Winkelstellung der Kippmulde 2 gegenüber dem Hubarm 1 im wesentlichen bestehen bleibt.By a further movement of the drive gear 18 of the lifting arm in the in Fig. 4c shown, upper end position moves. Meanwhile, the drive gear 29 moves synchronously, so that the angular position of the dump body 2 relative to the lift arm 1 is substantially maintained.

Es ist allerdings auch möglich, die Kippmulde 2 gegenüber dem Hubarm 1 zu verschwenken, wie in Fig. 5 gezeigt. Hier wird das Antriebszahnrad 18 nicht bewegt, so daß der Hubarm 1 seine Stellung, nämlich die obere Endstellung, beibehält. Durch eine Bewegung des Antriebszahnrads 29 wird die Kippmulde 2 aus der in Fig. 5a gezeigten, nach oben weisenden Stellung über eine Mittelstellung gemäß Fig. 5b in eine untere Stellung verschwenkt, die in Fig. 5c dargestellt ist. Die Verschwenkung der Kippmulde 2 erfolgt dadurch, daß das Antriebszahnrad 29 die erste Umlenkstange 33 bewegt, die ihrerseits den ersten Umlenkhebel 34 verschwenkt, wodurch die zweite Umlenkstange 38 bewegt wird. Die Bewegung der zweiten Umlenkstange 38 bewirkt eine Verschwenkung der Hebelstange 40 und damit eine Bewegung des Kipphebels 43, der die Kippmulde 2 um die Achse 6 verschwenkt.However, it is also possible to pivot the dump body 2 with respect to the lifting arm 1, as in Fig. 5 shown. Here, the drive gear 18 is not moved, so that the lifting arm 1 maintains its position, namely the upper end position. By a movement of the drive gear 29, the dump body 2 from the in Fig. 5a shown, pointing upward position about a center position according to Fig. 5b pivoted to a lower position in Fig. 5c is shown. The pivoting of the dump body 2 is effected in that the drive gear 29, the first deflecting rod 33 moves, which in turn pivots the first lever 34, whereby the second deflecting rod 38 is moved. The movement of the second deflecting rod 38 causes a pivoting of the lever rod 40 and thus a movement of the rocker arm 43, which pivots the dump body 2 about the axis 6.

Fig. 6 zeigt die Kombination beider Bewegungen. In Fig. 6a, b, c befindet sich der Hubarm 1 jeweils in seiner oberen Endstellung, und die Kippmulde 2 wird von einer nach unten gerichteten Stellung über eine Mittelstellung in eine nach oben gerichtete Stellung verschwenkt. In Fig. 6d, e, f befindet sich der Hubarm 1 in einer Mittelstellung, und die Kippmulde 2 wird von einer nach unten gerichteten Stellung über eine Mittelstellung in eine nach oben gerichtete Stellung verschwenkt. In Fig. 6g, h, i befindet sich der Hubarm 1 in seiner unteren Endstellung, und die Kippmulde 2 wird von einer nach unten gerichteten Stellung über eine Mittelstellung in eine nach oben gerichtete Stellung verschwenkt. Fig. 6 shows the combination of both movements. In Fig. 6a, b, c the lifting arm 1 is in each case in its upper end position, and the dump body 2 is pivoted from a downwardly directed position via a central position into an upwardly directed position. In Fig. 6d, e, f is the lifting arm 1 in a central position, and the dump body 2 is pivoted from a downward position via a central position in an upward position. In Fig. 6g, h, i is the lifting arm 1 in its lower end position, and the dump body 2 is pivoted from a downward position via a central position in an upward position.

Es ist allerdings auch möglich, das Schema der Fig. 6 nicht jeweils von links nach rechts, sondern von oben nach unten zu durchlaufen. Die Kippmulde 2 kann beispielsweise in die nach unten gerichtete Stellung gebracht werden, die in Fig. 6a, d, g gezeigt ist, und der Hubarm 1 kann in dieser Reihenfolge von oben nach unten verschwenkt werden, wobei die nach unten gerichtete Stellung der Kippmulde 2 erhalten bleibt. In gleicher Weise kann die Bewegung in der Reihenfolge der Fig. 6b, e, h oder der Fig. 6c, f, i durchlaufen werden oder die jeweils umgekehrte Bewegung.However, it is also possible the scheme of Fig. 6 not from left to right, but from top to bottom to go through. The dump body 2 can be brought into the downward position, for example, in the Fig. 6a, d, g is shown, and the lifting arm 1 can be pivoted in this order from top to bottom, wherein the downward position of the dump body 2 is maintained. In the same way, the movement in the order of Fig. 6b, e, h or the Fig. 6c, f, i be traversed or the reverse movement respectively.

Ferner ist es möglich, beide Bewegungen beliebig miteinander zu kombinieren.Furthermore, it is possible to combine both movements as desired.

Der erfindungsgemäße Spielzeug-Frontlader kann bei Spielfahrzeugen in einem beliebigen Maßstab realisiert werden, insbesondere bei Spielfahrzeugen im Maßstab 1:32. Die Zahnräder der Getriebestufen können aus Kunststoff hergestellt sein. Die erfindungsgemäße Lösung ist montagefreundlich und reparaturfreundlich. Sie kann in einer realitätsnahen Optik hergestellt werden. Die Erfindung kann mit einem mechanischen Hubarm und einem Kipphebelgestänge sowie darauf abgestimmten Getrieben mit zwei mechatronischen Antrieben, welche die Hebe- und Kippfunktion verwirklichen, realisiert werden. Die Kippfunktion der Kippmulde oder des sonstigen Anbaugeräts wird über ein exakt proportioniertes Hebelgestänge umgesetzt, welches aus Draht oder verstärktem Kunststoff besteht. Der Hubarm und die Kippmulde können aus leichtgewichtigen Materialien hergestellt werden, und sie können, äquivalent zum Original, multifunktional gewechselt werden. Der Hubarm kann aus Gründen der Festigkeit und Spielsicherheit aus festen und stabilen Materialien gefertigt werden. Er kann fahrzeugspezifisch angepaßt werden.The toy front loader according to the invention can be realized in toy vehicles on any scale, especially in toy vehicles in the scale 1:32. The gears of the gear stages can be made of plastic. The solution according to the invention is easy to install and easy to repair. It can be produced in a realistic look. The invention can be realized with a mechanical lifting arm and a rocker arm linkage and matched transmissions with two mechatronic drives, which realize the lifting and tilting function. The tilting function of the dump body or other attachment is implemented via a precisely proportioned lever linkage, which consists of wire or reinforced plastic. The lift arm and dump body can be made from lightweight materials and can be changed to a multi-functional equivalent to the original. The lifting arm can be made of solid and stable materials for reasons of strength and safety. It can be adapted to the vehicle.

Das Getriebegehäuse und das Motorgehäuse beherbergen zwei unabhängig voneinander ansteuerbare Antriebseinheiten, die aus Gründen der Spielsicherheit mit Rutschkupplungen ausgestattet sind, so daß bei unsachgemäßem Gebrauch Beschädigungen und Verletzungen, insbesondere das Quetschen von Fingern, verhindert werden.The gear housing and the motor housing accommodate two independently controllable drive units, which are equipped for reasons of game safety with slip clutches, so that when improper use damage and injury, especially the squeezing of fingers, are prevented.

Während der Kippfunktion wirkt nur einer der beiden Antriebe. Bei der Hebefunktion arbeiten beide Antriebe synchron zueinander, um die Kippmulde oder das sonstige Anbaugerät beim Heben des Hubarms in seiner beispielsweise waagrechten Position zu halten. Dabei kann der Antrieb für die Kippmulde permanent und in Winkelabhängigkeit zu der Bewegung des Hubarms nachgeregelt werden. Die dafür erforderliche Elektronik einschließlich der Winkelerfassung kann sich direkt an den Antrieben befinden.During the tilt function, only one of the two drives is effective. In the lifting function both drives work synchronously to each other to hold the dump body or other attachment when lifting the lift arm in its example horizontal position. In this case, the drive for the dump body can be readjusted permanently and in angular dependence to the movement of the lifting arm. The required electronics including the angle detection can be located directly on the drives.

Die Erfindung kann in Modulbauweise realisiert werden. Dadurch ist der Spielzeug-Frontlader besonders montagefreundlich und reparaturfreundlich und kann zudem günstig hergestellt werden. Ferner wird dadurch die Möglichkeit geschaffen, den Spielzeug-Frontlader entsprechend dem Original mit wenigen Handgriffen an das Fahrzeug anzubauen oder von dem Fahrzeug zu entfernen.The invention can be realized in modular construction. As a result, the toy front loader is particularly easy to install and easy to repair and can also be manufactured cheaply. Furthermore, this creates the opportunity to grow the toy front loader according to the original with a few simple steps to the vehicle or remove it from the vehicle.

Die hauptsächlich aus Kunststoff hergesellten Bauteile lassen den Geräuschpegel und den Herstellungspreis sinken. In Folge seiner Konstruktion und Materialwahl kann der Spielzeug-Frontlader nahezu verschleißfrei hergestellt werden. Er kann in verschiedene Fahrzeugtypen integriert werden. Beide Antriebe können platzsparend und kostengünstig in einem einzigen Motor- und Getriebegehäuse untergebracht werden.The mainly plastic-made components reduce the noise level and the production price. Due to its design and choice of materials, the toy front loader can be manufactured almost wear-free. It can be integrated into different vehicle types. Both drives can be accommodated in a space-saving and cost-effective in a single engine and transmission housing.
