Description

Die Erfindung betrifft ein Fahrspielzeug, insbesondere für spurgeführte Autorennbahnen, mit einem Antriebsmotor, welcher eine Antriebswelle aufweist, und mit einer angetriebenen Achse mit Rädern, wobei zwischen der Antriebswelle und der angetriebenen Achse ein Getriebe angeordnet ist, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a driving toy, in particular for track-guided car racing tracks, with a drive motor, which has a drive shaft, and with a driven axle with wheels, being between the drive shaft and the driven axis, a gear is arranged, according to the preamble of Claim 1.

Beispielsweise bei spurgeführten Autorennbahnen ist es das Ziel, in einem Rennen ein Fahrspielzeug manuell unter Steuerung der Fahrgeschwindigkeit möglichst schnell über die Bahn zu führen, ohne daß dabei das Fahrspielzeug in unerwünschter Weise die Rennbahn verläßt. Herkömmlicherweise ist als Antrieb des Fahrspielzeugs ein Elektromotor vorgesehen, der in Fahrtrichtung längs eingebaut ist, wobei eine Antriebswelle an einem Ende des Motors herausragt und in einem Getriebe endet. Hierbei ist am getriebeseitigen Ende der Antriebswelle ein Ritzel angeordnet. Durch das Getriebe erstreckt sich ferner die gemeinsame Achse der angetriebenen Räder, welche ein Kronrad trägt. In dem Getriebe greifen das Ritzel und das Kronenrad ineinander, wobei eine unterschiedliche Zähnezahl von Ritzel und Kronenrad eine entsprechende Übersetzung bewirkt.For example, in track-guided car racing tracks, the goal is in a race a driving toy manually under control of the driving speed if possible to run quickly on the train without the undesirable toy Way leaves the racetrack. Conventionally, as the drive of the Driving toy provided an electric motor, which is installed lengthways in the direction of travel is, with a drive shaft protruding at one end of the motor and in one Transmission ends. Here is a pinion at the gear end of the drive shaft arranged. The common axis also extends through the transmission driven wheels, which carries a crown wheel. The pinion engages in the gearbox and the crown gear into each other, with a different number of teeth of pinion and crown gear causes a corresponding translation.

Aus der DE 27 22 734 A1 ist ferner ein lenkbares Fahrspielzeug bekannt, bei dem über die Drehrichtung des Elektromotors die Vorderradlenkung des Fahrzeugs unter Einschaltung einer Kupplungseinrichtung in die rechte oder linke Endlage gebracht wird, um das Fahrspielzeug von einer Fahrbahnseite zur anderen Fahrbahnseite zu lenken. Damit trotz wechselnder Drehrichtung des Elektromotors das Fahrspielzeug immer in dieselbe Richtung angetrieben wird, ist an einer Antriebswelle des Elektromotors ein Käfig schwenkbar angeordnet, welcher neben einem fest mit der Antriebswelle verbundenen ersten Ritzel ein zweites Ritzel, welches in Eingriff mit dem ersten Ritzel steht, umgreift. Je nach Drehrichtung des Elektromotors schwenkt der Käfig in eine jeweilige Endlage und bringt in einer ersten Endlage das zweite Ritzel mit einem ersten Kronrad und das zweite Ritzel mit einem zweiten Kronrad in Eingriff, wobei die beiden Kronräder auf einer Achse von angetriebenen Rädern angeordnet sind. Durch diese Anordnung wird die Achse der angetriebenen Räder unabhängig von der Drehrichtung des Elektromotors immer in dieselbe Richtung angetrieben.A steerable driving toy is also known from DE 27 22 734 A1, in which the front wheel steering of the vehicle via the direction of rotation of the electric motor with the engagement of a coupling device in the right or left end position is brought to the driving toy from one side of the road to the other side of the road to steer. So despite the changing direction of rotation of the electric motor Driving toys are always driven in the same direction is on a drive shaft of the electric motor a cage is pivotally arranged, which next to one firmly connected to the drive shaft first pinion a second pinion, which in Engagement with the first pinion is available, engages. Depending on the direction of rotation of the electric motor the cage swivels into a respective end position and brings in a first End position of the second sprocket with a first crown gear and the second sprocket with one second crown wheel engaged, the two crown wheels on an axis of driven wheels are arranged. With this arrangement, the axis of the driven wheels regardless of the direction of rotation of the electric motor always driven in the same direction.

Es ist Aufgabe der vorliegenden Erfindung, ein Fahrspielzeug der o.g. Art dahingehend zu verbessern, daß ein noch realistischeres Fahr- und Steuerverhalten bzgl. der Geschwindigkeitskontrolle erzielt wird.It is an object of the present invention to provide a driving toy of the above. Kind of that to improve that more realistic driving and control behavior speed control is achieved.

Vorteilhafte Ausgestaltungen ergeben sich aus den weiteren Ansprüchen.This task is performed by a driving toy from the above. Kind with those in claim 1 marked features solved. Advantageous configurations result from the other claims.

Dazu ist es erfindungsgemäß vorgesehen, daß das Getriebe als ein von der Drehrichtung des Antriebsmotors geschaltetes Schaltgetriebe ausgebildet ist, welches zwei Gänge mit unterschiedlichem Übersetzungsverhältnis aufweist, wobei ein erster Gang einer ersten Drehrichtung des Antriebsmotors und ein zweiter Gang einer der ersten Drehrichtung entgegengesetzten Drehrichtung des Aniriebsmotors zugeordnet ist.For this purpose, it is provided according to the invention that the gear as one of the direction of rotation of the drive motor switched gearbox is formed, which has two gears with different transmission ratio, one first gear of a first direction of rotation of the drive motor and a second gear a direction of rotation of the drive motor opposite to the first direction of rotation assigned.

Dies hat den Vorteil, daß auf einfache Weise und ohne zusätzliche Schaltmittel eine Gangschaltung mit unterschiedlichen Übersetzungen zwischen der Antriebswelle und der angetriebenen Achse ausgebildet ist. Hierdurch ist das Fahrspielzeug um die zusätzliche Funktion einer Gangschaltung erweitert, ohne daß für diese Gangschaltung im Fahrspielzeug zusätzliche Steuerorgane vorgesehen werden müssen. Die Umschaltung zwischen den Gängen erfolgt beispielsweise durch Umpolung, Frequenzänderung oder Phasenverschiebung der Fahrspannung, was eine Drehrichtungsumkehr des Antriebsmotors zur Folge hat.This has the advantage that in a simple manner and without additional switching means a gear shift with different ratios between the drive shaft and the driven axis is formed. This is the driving toy extended by the additional function of a gear shift without that for this gearshift provided additional control elements in the vehicle Need to become. Switching between the gears takes place, for example through polarity reversal, frequency change or phase shift of the driving voltage, which results in a reversal of the direction of rotation of the drive motor.

Bevorzugt weist das Schaltgetriebe zwei Gänge auf, wobei ein erster Gang einer ersten Drehrichtung des Motors und ein zweiter Gang einer der ersten Drehrichtung entgegengesetzten Drehrichtung des Motors zugeordnet ist.The manual transmission preferably has two gears, a first gear being one first direction of rotation of the motor and a second gear one of the first direction of rotation opposite direction of rotation of the motor is assigned.

Zweckmäßigerweise ist das Getriebe derart ausgebildet, daß unabhängig von der Drehrichtung des Antriebsmotors der Antrieb der angetriebenen Achse immer in derselben Richtung erfolgt.Advantageously, the transmission is designed such that regardless of the Direction of rotation of the drive motor the drive of the driven axis always in in the same direction.

In einer bevorzugten Weiterbildung der Erfindung weist das Getriebe eine mechanische Sperre mit zwei Stellungen auf, welche derart ausgebildet und angeordnet ist, daß in einer ersten Stellung der mechanischen Sperre ein Schaltvorgang des Getriebes bei Drehrichtungswechsel des Antriebsmotors unterbunden ist und in einer zweiten Stellung der mechanischen Sperre der Schaltvorgang frei möglich ist. Hierdurch ist mittels Drehrichtungsumkehr des Antriebsmotors wahlweise ein Betrieb mit Vorwärts- und Rückwärtsfahrt oder mit unterschiedlichen Gängen möglich.In a preferred development of the invention, the transmission has a mechanical one Lock with two positions, which are designed and arranged in this way is that in a first position of the mechanical lock a switching operation of the Gearbox is prevented when changing the direction of rotation of the drive motor and in a second position of the mechanical lock the switching process freely possible is. As a result, a reversal of the direction of rotation of the drive motor is optional Operation with forward and reverse travel or with different gears possible.

Eine ggf. vorhandene mechanische Sperre ist dabei derart ausgelegt, daß diese in verriegelter Stellung ein verschwenken des Käfigs verhindert. In a particularly preferred embodiment, the gearbox includes a first pinion, which is non-rotatably connected to the drive shaft, a cage, which is rotatably connected to the drive shaft, the cage a second Pinion holds in engagement with the first pinion and together with the second pinion pivotable about the drive shaft as a pivot axis between two end positions is a first non-rotatably connected to the driven axis Gear and a second non-rotatably connected to the driven axis Gear, the first and second gear having different numbers of teeth and are arranged such that in a first end position of the cage the second pinion with the first gear and in a second end position of the Cages the second pinion with the second gear meshes.

Die in den Fig. 1 bis 4 lediglich ausschnittsweise dargestellte bevorzugte Ausführungsform eines erfindungsgemäßen Fahrspielzeugs umfaßt einen Antriebsmotor 10, eine Antriebswelle 12, eine angetriebene Achse 14 für nicht dargestellte Räder und ein zwischen Antriebswelle 12 und angetriebener Achse 14 angeordnetes Getriebe 16. The preferred embodiment shown only in sections in FIGS. 1 to 4 of a driving toy according to the invention comprises a drive motor 10, a drive shaft 12, a driven axle 14 for wheels, not shown and one arranged between the drive shaft 12 and the driven axle 14 Gear 16.

Das Getriebe umfaßt ein erstes Ritzel 18, welches drehfest mit der Antriebswelle 12 verbunden ist, einen Käfig 20, welcher drehbar mit der Antriebswelle 12 verbunden ist, ein drehfest mit der angetriebenen Achse 14 verbundenes erstes Kronrad 22 und ein drehfest mit der angetriebenen Achse 14 verbundenes zweites Kronrad 24. Der Käfig 20 umgreift das erste Ritzel 18 und trägt zusätzlich ein zweites Ritzel 26 derart, daß es in Eingriff mit dem ersten Ritzel 18 steht.The transmission comprises a first pinion 18, which is rotatably connected to the drive shaft 12 is connected, a cage 20 which is rotatably connected to the drive shaft 12 is a first rotationally fixedly connected to the driven axle 14 Crown gear 22 and a second non-rotatably connected to the driven axle 14 Crown gear 24. The cage 20 encompasses the first pinion 18 and additionally enters second pinion 26 such that it engages with the first pinion 18.

Der Käfig 20 ist derart angeordnet und ausgebildet, daß dieser zusammen mit dem zweiten Ritzel 26 um die Antriebswelle als Schwenkachse zwischen zwei Endstellungen verschwenkbar ist, ohne daß dabei der Eingriff zwischen erstem Ritzel 18 und zweitem Ritzel 26 verloren geht. In den Endstellungen schlägt der Käfig 20 an entsprechenden Anschlägen 28 (Fig. 2 und 4) an. Die beiden Kronräder 22, 24 sind derart angeordnet, daß in einer ersten Endstellung des Käfigs 20, wie in Fig. 1 und 2 dargestellt, das zweite Ritzel 26 mit dem ersten Kronrad 22 kämmt und in einer zweiten Endstellung des Käfigs 20, wie in Fig. 3 und 4 dargestellt, das zweite Ritzel 26 mit dem zweiten Kronrad 24 kämmt.The cage 20 is arranged and designed such that it together with the second pinion 26 around the drive shaft as a pivot axis between two End positions is pivotable without the intervention between the first Pinion 18 and second pinion 26 is lost. In the end positions the strikes Cage 20 on corresponding stops 28 (Fig. 2 and 4). The two crown wheels 22, 24 are arranged such that in a first end position of the cage 20, 1 and 2, the second pinion 26 with the first crown gear 22nd combs and in a second end position of the cage 20, as shown in FIGS. 3 and 4, the second pinion 26 meshes with the second crown wheel 24.

Das erstes Kronrad 22 weist eine geringere Zähnezahl auf als das zweite Kronrad 24, so daß sich in den beiden Endstellungen des Käfigs 20 unterschiedliche Übersetzungsverhältnisse von der Antriebswelle 12 auf die angetriebene Achse 14 ergeben.The first crown gear 22 has a smaller number of teeth than the second crown gear 24, so that there are 20 different transmission ratios in the two end positions of the cage result from the drive shaft 12 on the driven shaft 14.

Die drehbare Verbindung zwischen der Antriebswelle 12 und dem Käfig 20 ist derart ausgebildet, daß sich bei einem Wechsel der Drehrichtung der Antriebswelle 12 zunächst der Käfig 20 mit der Antriebswelle 12 mitdreht, bis der Käfig 20 an einem der Anschläge 28 anschlägt. Der Käfig 20 bleibt in der jeweiligen Endstellung, wobei sich die Antriebswelle 12 weiter dreht und den Käfig 20 gegen den jeweiligen Anschlag 28 drückt, so daß ein kraftübertragender Eingriff zwischen dem zweiten Ritzel 26 und dem jeweiligen Kronrad 22 bzw. 24 sichergestellt ist.The rotatable connection between the drive shaft 12 and the cage 20 is such trained that when changing the direction of rotation of the drive shaft 12 first rotates the cage 20 with the drive shaft 12 until the cage 20 on strikes one of the stops 28. The cage 20 remains in the respective end position, the drive shaft 12 continues to rotate and the cage 20 against the presses respective stop 28 so that a force-transmitting engagement between the second pinion 26 and the respective crown wheel 22 or 24 is ensured.

Fig. 1 und 2 veranschaulichen die Situation, in der sich die Antriebswelle 12 und mit dieser das erste Ritzel 18 in die mit Pfeil 30 angedeutete erste Richtung dreht. Der Käfig 20 liegt am in Fig. 2 oberen Anschlag 28 an und das zweite Ritzel 26 kämmt mit dem ersten Kronrad 22 und treibt dadurch die angetriebene Achse 14 in Pfeilrichtung 34 an. Mit anderen Worten ist ein erster Gang eingelegt, mit einer entsprechenden Übersetzung von Antriebsmotor 10 zu angetriebener Achse 14.1 and 2 illustrate the situation in which the drive shaft 12 and with this the first pinion 18 rotates in the first direction indicated by arrow 30. The cage 20 lies against the upper stop 28 in FIG. 2 and the second pinion 26 meshes with the first crown wheel 22 and thereby drives the driven axle 14 in the direction of arrow 34. In other words, a first gear is engaged, with one corresponding translation from drive motor 10 to driven axis 14.

Nach einer Umkehrung der Drehrichtung der Antriebswelle 12 gemäß Pfeil 32 in Fig. 4 schwenkt der Käfig 20 von der in Fig. 1 dargestellten oberen Position in die in Fig. 3 dargestellte untere Position, so daß nunmehr der Käfig 20 an dem in Fig. 4 unteren Anschlag 28 anliegt und das zweite Ritzel 26 mit dem zweiten Kronrad 24 kämmt. Dadurch treibt das zweite Ritzel 26 die angetriebene Achse 14 in Pfeilrichtung 34 an (Fig. 4). Mit anderen Worten ist nun ein zweiter Gang eingelegt mit einer bzgl. dem ersten Gang niedrigeren Übersetzung. Wie sich aus dem direkten Vergleich der Fig. 2 und 4 ergibt, erfolgt trotz der Drehrichtungsumkehr des Antriebsmotors 10 der Antrieb der Achse 14 bei beiden Gängen in dieselbe Richtung 34.After a reversal of the direction of rotation of the drive shaft 12 according to arrow 32 in Fig. 4 pivots the cage 20 from the upper position shown in Fig. 1 in the 3 shown lower position, so that now the cage 20 on the in Fig. 4 abuts the lower stop 28 and the second pinion 26 with the second crown wheel 24 combs. As a result, the second pinion 26 drives the driven axle 14 in Direction of arrow 34 (Fig. 4). In other words, a second gear is now engaged with a gear ratio lower than the first gear. As can be seen from the direct Comparison of FIGS. 2 and 4 results, despite the reversal of the direction of rotation Drive motor 10 the drive of the axis 14 in both gears in the same direction 34th

Bemerkenswert ist, daß dieses Schaltgetriebe 16 ohne zusätzliche fern zu bedienende Schaltmittel realisiert ist. Statt eines zusätzlichen Schaltmittels erfolgt eine Schaltung zwischen den Gängen mittels einer Drehrichtungsumkehr des Antriebsmotors 10.It is noteworthy that this manual transmission 16 without additional remote control Switching means is realized. Instead of an additional switching means there is a Shift between the gears by reversing the direction of rotation of the drive motor 10th

Wie sich aus einem direkten Vergleich der Fig. 1 und 3 ergibt, weist das zweite Ritzel 26 eine derartige axiale Länge auf, daß trotz des unterschiedlichen Durchmessers von erstem und zweitem Kronrad 22, 24 in den beiden Endstellungen des Käfigs 20 ein sicherer Eingriff des zweiten Ritzels 26 in das jeweilige Kronrad 22 bzw. 24 möglich ist.As can be seen from a direct comparison of FIGS. 1 and 3, the second one Pinion 26 has an axial length such that despite the different diameters of the first and second crown gear 22, 24 in the two end positions of the Cage 20 a secure engagement of the second pinion 26 in the respective crown gear 22nd or 24 is possible.

Die Fig. 5 bis 8 zeigen ein bevorzugte Weiterbildung der Erfindung, wobei funktionsgleiche Teile mit gleichen Bezugsziffern bezeichnet sind, so daß zu deren Erläuterung auf die obige Beschreibung der Fig. 1 bis 4 verwiesen wird. In dieser Ausführungsform gemäß Fig. 5 bis 8 ist zusätzlich eine mechanische Sperre 36 vorgesehen, welche wahlweise das Verschwenken des Käfigs 20 bei Drehrichtungswechsel des Antriebsmotors verhindert. Hierdurch ist ein Betrieb des Fahrspielzeugs mit Vorwärts- und Rückwärtsfahrt möglich. Die mechanische Sperre 36 wird beispielsweise manuell betätigt. 5 to 8 show a preferred development of the invention, with the same function Parts are designated by the same reference numerals, so that their explanation reference is made to the above description of FIGS. 1 to 4. In this 5 to 8 is a mechanical lock 36 provided which optionally the pivoting of the cage 20 when changing direction of rotation of the drive motor prevented. As a result, the vehicle is operated possible with forward and backward travel. The mechanical lock 36 is operated manually, for example.

Fig. 5 veranschaulicht eine Situation, in der der Käfig 20 in Stellung "erster Gang" steht (analog Fig. 1 und 2), wobei jedoch die mechanische Sperre 36 verriegelt ist, so daß ein Verschwenken des Käfigs 20 blockiert ist. Wenn sich nun die Drehrichtung der Antriebsachse 12 ändert, wie mit Doppelpfeil 38 angedeutet, so ändert sich auch die Drehrichtung der angetriebenen Achse 14, wie mit Doppelpfeil 34 angedeutet. Somit fährt das Fahrspielzeug je nach Drehrichtung des Antriebsmotors vorwärts oder rückwärts, wobei eine Umschaltung vom ersten Gang in den zweiten Gang durch die mechanische Sperre 36 verhindert ist. In Fig. 6 ist die mechanische Sperre 36 entriegelt, so daß der Käfig 20 bei Drehrichtungswechsel der Antriebsachse 12 wieder entsprechend verschwenken kann. Es ergibt sich ein Betrieb mit erstem und zweitem Gang analog der obigen Beschreibung zu Fig. 1 und 2.5 illustrates a situation in which the cage 20 is in the "first gear" position. stands (analogous to FIGS. 1 and 2), but the mechanical lock 36 is locked, so that pivoting of the cage 20 is blocked. If now the direction of rotation the drive axis 12 changes, as indicated by double arrow 38, so changes the direction of rotation of the driven axis 14, as with a double arrow 34 indicated. The driving toy thus moves depending on the direction of rotation of the drive motor forward or backward, with a shift from first gear to second gear is prevented by the mechanical lock 36. 6 is the mechanical Lock 36 unlocked so that the cage 20 when changing the direction of rotation Drive axis 12 can pivot accordingly again. It results in a Operation with first and second gear analogous to the description above for FIG. 1 and 2.

Fig. 7 veranschaulicht eine Situation, in der der Käfig 20 in Stellung "zweiter Gang" steht (analog Fig. 3 und 4), wobei jedoch die mechanische Sperre 36 verriegelt ist, so daß ein Verschwenken des Käfigs 20 blockiert ist. Wenn sich nun die Drehrichtung der Antriebsachse 12 ändert, wie mit Doppelpfeil 38 angedeutet, so ändert sich auch die Drehrichtung der angetriebenen Achse 14, wie mit Doppelpfeil 34 angedeutet. Somit fährt das Fahrspielzeug je nach Drehrichtung des Antriebsmotors vorwärts oder rückwärts, wobei eine Umschaltung vom zweiten Gang in den ersten Gang durch die mechanische Sperre 36 verhindert ist. In Fig. 8 ist die mechanische Sperre 36 entriegelt, so daß der Käfig 20 bei Drehrichtungswechsel der Antriebsachse 12 wieder entsprechend verschwenken kann. Es ergibt sich ein Betrieb mit erstem und zweitem Gang analog der obigen Beschreibung zu Fig. 3 und 4.7 illustrates a situation in which the cage 20 is in the "second" position Gear "is (analog. Fig. 3 and 4), but the mechanical lock 36 locked is, so that pivoting of the cage 20 is blocked. If now Direction of rotation of the drive axis 12 changes, as indicated by double arrow 38, so the direction of rotation of the driven axis 14 also changes, as with a double arrow 34 indicated. The driving toy thus moves depending on the direction of rotation of the drive motor forward or backward, shifting from second gear is prevented in the first gear by the mechanical lock 36. 8 is the mechanical lock 36 unlocks, so that the cage 20 when changing direction the drive shaft 12 can pivot accordingly again. It results operation with first and second gear analogous to the description above 3 and 4.
