Description

Die Erfindung betrifft eine Übertragungsanordnung für ein Rad, insbesondere ein Rollstuhlrad, zur Übertragung einer elektrischen Größe von einer radseitigen Einrichtung an eine fahrzeugkörperseitige Einrichtung oder umgekehrt mit den Merkmalen des Oberbegriffs von Anspruch 1.The invention relates to a transmission arrangement for a wheel, in particular a wheelchair wheel, for transmitting an electrical variable from a wheel-side device to a vehicle body-side device or vice versa with the features of the preamble of claim 1.

An Rollstuhlrädern sind häufig Greifringe befestigt, welche zum einen dazu dienen, den Rollstuhl manuell anzutreiben. Zum anderen können die Greifringe mit einem Signalgeber zusammenwirken, der erfasst, mit welcher Kraft und in welcher Richtung an dem Greifring angegriffen wird. Der Signalgeber kann mit einem Hilfsantrieb in Verbindung stehen, der den Benutzer bei der Fortbewegung des Rollstuhls in Abhängigkeit von der vom Signalgeber erfassten Kraft unterstützt.On wheelchair wheels gripping rings are often attached, which serve on the one hand to drive the wheelchair manually. On the other hand, the gripping rings can cooperate with a signal generator, which detects with which force and in which direction is attacked on the gripping ring. The signal generator may be in communication with an auxiliary drive which assists the user in locomotion of the wheelchair in response to the force detected by the signal generator.

Wenn nun jedoch der Signalgeber an dem Rollstuhlrad, insbesondere im Bereich des Greifrings, angeordnet ist und der Antrieb fahrzeugkörperseitig angeordnet ist, muss eine Signalübertragung von dem radseitigen Signalgeber an den fahrzeugkörperseitigen Antrieb oder eine Antriebssteuerung erfolgen. Weiterhin ist es denkbar, dass eine Energieversorgung, beispielsweise eine Batterie oder ein Akku, an dem Fahrzeugkörper angeordnet ist und ein Radnabenmotor radseitig angeordnet ist. In diesem Fall muss die Energieversorgung von der Fahrzeugkörperseite an die Radseite erfolgen. Erschwerend kommt hinzu, dass Rollstühle in der Regel so ausgeführt sind, dass die Rollstuhlräder abnehmbar sind, um den Rollstuhl besser transportieren zu können. Eine elektrische Verbindung zwischen Rollstuhlrad und Fahrzeugkörper muss dabei entweder gelöst werden, oder es muss ein sehr langes Kabel vorgesehen werden, welches wiederum bei zusammengebautem Rollstuhl verstaut werden muss.However, if now the signal transmitter is arranged on the wheelchair wheel, in particular in the region of the gripping ring, and the drive is arranged on the vehicle body side, a signal transmission from the wheel-side signal transmitter to the vehicle body side drive or a drive control must take place. Furthermore, it is conceivable that a power supply, for example a battery or a rechargeable battery, is arranged on the vehicle body and a wheel hub motor is arranged on the wheel side. In this case, the power supply must be from the vehicle body side to the wheel side. To make matters worse, that wheelchairs are usually designed so that the wheelchair wheels are removable in order to better transport the wheelchair can. An electrical connection between wheelchair wheel and vehicle body must either be solved, or it must be provided a very long cable, which in turn must be stowed when assembled wheelchair.

Die US 5,771,988 offenbart ein motorisch angetriebenes Fahrzeug mit einem Fahrzeugkörper. Ein Rad weist eine feststehende Achse auf, die mit dem Körper verbunden ist. Das Rad weist eine Fahranordnung auf. Eine Handhabungseinheit ist am Fahrzeugkörper angeordnet und liefert ein elektrisches Signal, welches an die Fahranordnung geliefert werden muss. Die feststehende Achse weist einen Hohlraum auf und eine Signalleitung, die die Handhabungseinheit und durch die Fahranordnung miteinander verbindet, ist in dem Hohlraum angeordnet.The US 5,771,988 discloses a motor vehicle with a vehicle body. A wheel has a fixed axis which is connected to the body. The wheel has a driving arrangement. A handling unit is disposed on the vehicle body and provides an electrical signal which must be supplied to the drive assembly. The fixed axle has a cavity, and a signal line connecting the handling unit and the traveling assembly is disposed in the cavity.

Die US 4,021,690 offenbart ein Rad, welches auf einer Achse angeordnet ist, die einen Hohlraum aufweist, in der elektrische Leitungen angeordnet sind.The US 4,021,690 discloses a wheel which is disposed on an axis having a cavity in which electrical lines are arranged.

Aus der DE 298 03 665 U1 ist ein Antrieb für einen Rollstuhl mit einem Außenläufermotor bekannt. Ein Rad weist eine Steckachse auf, in der eine elektrische Leitung angeordnet ist und über die das Rad an einem Fahrzeug befestigbar ist.From the DE 298 03 665 U1 is known a drive for a wheelchair with an external rotor motor. A wheel has a thru axle, in the an electrical line is arranged and via which the wheel can be fastened to a vehicle.

Aus der US 5,427,193 ist eine Übertragungsanordnung für ein Rad zur Übertragung einer elektrischen Größe bekannt, wobei an dem Rad eine Steckachse vorgesehen ist, die auf eine fahrzeugseitige Hülse aufgesteckt werden kann und dort verriegelt werden kann. Zur Übertragung von Signalen ist entlang des Mantels der Steckachse eine Übertragungsleitung vorgesehen.From the US 5,427,193 a transmission arrangement for a wheel for transmitting an electrical variable is known, wherein on the wheel a thru-axle is provided, which can be plugged onto a vehicle-side sleeve and can be locked there. For the transmission of signals, a transmission line is provided along the jacket of the thru-axle.

Aufgabe der vorliegenden Erfindung ist es, eine Übertragungsanordnung zur Übertragung einer elektrischen Größe anzugeben, mit der die oben genannten Nachteile überwunden werden.The object of the present invention is to specify a transmission arrangement for transmitting an electrical variable with which the abovementioned disadvantages are overcome.

Gelöst wird diese Aufgabe erfindungsgemäß durch eine Übertragungsanordnung für ein Rad, insbesondere ein Rollstuhlrad, mit den Merkmalen des Anspruchs 1.This object is achieved according to the invention by a transmission arrangement for a wheel, in particular a wheelchair wheel, with the features of claim 1.

Eine radseitige Einrichtung kann beispielsweise ein Signalgeber sein, dessen Ausgangssignal - gegebenenfalls nach einer Signalverarbeitung - über die Übertragungsanordnung an einen fahrzeugkörperseitigen Antrieb oder eine fahrzeugkörperseitige Antriebssteuerung übergeben wird. Als elektrische Größe wird somit ein Signal übergeben. Weiterhin kann die radseitige Einrichtung beispielsweise ein radseitiger Antrieb sein. In diesem Fall wird von einer fahrzeugkörperseitigen Energieversorgung als fahrzeugkörperseitiger Einrichtung Energie über die Übertragungsanordnung an den radseitigen Antrieb übertragen. Als elektrische Größe wird in diesem Fall Strom oder Spannung übertragen.A wheel-side device may be, for example, a signal generator, the output signal of which - optionally after a signal processing - is transferred via the transmission arrangement to a vehicle body-side drive or a vehicle body-side drive control. As electrical variable thus a signal is transferred. Furthermore, the wheel-side device may be, for example, a wheel-side drive. In this case, energy is transmitted via the transmission arrangement to the wheel-side drive by a vehicle body-side power supply as vehicle body-side device. As an electrical variable in this case, power or voltage is transmitted.

Zur mechanischen Befestigung eines Rads an einem Fahrzeugkörper, insbesondere Fahrzeuggestell, z. B. Rollstuhlrad an einem Rollstuhlgestell, ist es bereits gebräuchlich, Steckachsen zu verwenden. Mittels Steckachsen kann ein Rad besonders einfach an einem Fahrzeugkörper angebracht und auch wieder demontiert werden. Die erfindungsgemäße Lösung schlägt vor, diese für einen Benutzer bekannte Lösung zur mechanischen Befestigung beizubehalten und sie zusätzlich zur Übertragung einer elektrischen Größe zu adaptieren. Erfindungsgemäß ist die Steckachse vorzugsweise als Hohlzylinder ausgebildet, wobei innerhalb des Hohlzylinders die zumindest eine Übertragungsleitung geführt ist.For the mechanical attachment of a wheel to a vehicle body, in particular vehicle frame, z. B. Wheelchair wheel on a wheelchair frame, it is already common to use thru axles. By means of thru axles, a wheel can be attached to a vehicle body in a particularly simple manner and also dismantled again. The solution according to the invention proposes to maintain this mechanical fastening solution known to a user and to adapt it in addition to transmitting an electrical quantity. According to the invention, the thru axle preferably formed as a hollow cylinder, wherein the at least one transmission line is guided within the hollow cylinder.

Gemäß einer besonders bevorzugten Ausgestaltung kann vorgesehen sein, dass die zumindest eine Übertragungsleitung in einem Stecker endet, der bei montiertem Rad in einen fahrzeugkörperseitigen Stecker eingesteckt ist. Dies hat den Vorteil, dass gleichzeitig mit der Montage des Rads an dem Fahrzeug die elektrische Verbindung hergestellt wird, da beim Einstecken der Steckachse auch die beiden Stecker ineinander gesteckt werden. Für die elektrische Verbindung ist somit keine zusätzliche Positionierung und Ausrichtung des Rollstuhlrads bei der Montage erforderlich. Es erfolgt somit eine radial positionsfreie elektrische Verbindung. Auch ist kein weiterer zusätzlicher Handgriff erforderlich, um die elektrische Verbindung herzustellen.According to a particularly preferred embodiment, it may be provided that the at least one transmission line terminates in a plug which is plugged into a vehicle body side connector when the wheel is mounted. This has the advantage that the electrical connection is made simultaneously with the mounting of the wheel on the vehicle, since when inserting the thru axle and the two connectors are plugged into each other. Thus, no additional positioning and alignment of the wheelchair wheel during assembly is required for the electrical connection. There is thus a radially position-free electrical connection. Also, no additional additional handle is required to make the electrical connection.

Besonders bevorzugt ist es, wenn im Bereich der Radnabe zumindest ein Schleifkontakt zur Übergabe der elektrischen Größe an die zumindest eine Übertragungsleitung bzw. umgekehrt vorgesehen ist. Durch diese Maßnahme ist eine Übertragung der elektrischen Größe bei rotierendem Rad möglich.It is particularly preferred if, in the region of the wheel hub, at least one sliding contact is provided for transferring the electrical variable to the at least one transmission line or vice versa. By this measure, a transmission of the electrical variable is possible with a rotating wheel.

Eine besonders klein bauende Ausgestaltung ergibt sich, wenn auf der Steckachse ein elektrisch leitfähiger Ring angeordnet ist, der mit einer Übertragungsleitung verbunden ist und an dem ein Kontaktelement gleitet. Vorzugsweise ist der elektrisch leitfähige Ring drehfest auf der Steckachse angeordnet. Durch den elektrisch leitfähigen Ring wird somit beispielsweise ein Signal eines Signalgebers aufgenommen und über die Übertragungsleitung an die Fahrzeugkörperseite übertragen. Das Kontaktelement kann beispielsweise als Kohlebürste ausgebildet sein. Der elektrisch leitfähige Ring kann beispielsweise aus Kupfer, Messing oder Bronze ausgebildet sein.A particularly small structural design results when an electrically conductive ring is arranged on the plug-in axis, which is connected to a transmission line and to which a contact element slides. Preferably, the electrically conductive ring is rotatably mounted on the plug-in axis. Thus, for example, a signal of a signal transmitter is received by the electrically conductive ring and transmitted via the transmission line to the vehicle body side. The contact element may be formed, for example, as a carbon brush. The electric conductive ring may be formed, for example, copper, brass or bronze.

Besonders bevorzugt ist es, wenn auf der Steckachse mehrere elektrisch leitfähige Ringe, die zueinander elektrisch isoliert sind, angeordnet sind, die mit jeweils einer Übertragungsleitung verbunden sind und an denen jeweils ein Kontaktelement gleitet. Dadurch ist es möglich, beispielsweise mehrere Sensorsignale über die Steckverbindung zwischen Rad und Fahrzeugkörper zu übertragen. Insbesondere können somit Vorwärts- und Rückwärtsbewegung des Rades anzeigende Signale übertragen werden. Wenn die Steckachse selbst aus einem elektrisch leitfähigen Material ausgebildet ist, kann eine Hülse aus elektrisch isolierendem Material auf der Steckachse angeordnet sein und auf dieser Hülse können wiederum die Ringe angeordnet sein. Zwischen den leitfähigen Ringen kann die Hülse einen radialen, umlaufenden Steg aufweisen, der die benachbarten leitfähigen Ringe in axialer Richtung zueinander elektrisch isoliert.It is particularly preferred if a plurality of electrically conductive rings, which are electrically insulated from one another, are arranged on the plug-in axis, which are each connected to a transmission line and on each of which a contact element slides. This makes it possible, for example, to transmit a plurality of sensor signals via the plug connection between the wheel and the vehicle body. In particular, thus forward and backward movement of the wheel indicating signals can be transmitted. If the plug-in axis itself is formed from an electrically conductive material, a sleeve made of electrically insulating material can be arranged on the plug-in axis and in turn the rings can be arranged on this sleeve. Between the conductive rings, the sleeve may have a radial, circumferential ridge, which electrically isolates the adjacent conductive rings in the axial direction.

Gemäß einer Ausgestaltung der Erfindung kann radseitig eine Platine vorgesehen sein, die mit der radseitigen Einrichtung und zumindest einem Kontaktelement verbunden ist. Auf der Platine kann eine Signalbearbeitung oder -verarbeitung durchgeführt werden. Insbesondere kann die Signalanzahl reduziert werden, sodass über die Steckachse nur noch wenige Signale übertragen werden müssen.According to one embodiment of the invention, a board can be provided on the wheel side, which is connected to the wheel-side device and at least one contact element. Signal processing can be performed on the board. In particular, the number of signals can be reduced so that only a few signals have to be transmitted via the plug-in axis.

Die Platine kann in einem radseitigen Gehäuse angeordnet sein. Dadurch ist die Platine vor äußeren Einflüssen geschützt. Das Gehäuse kann einen abnehmbaren Deckel aufweisen, wodurch die Wartung erleichtert wird. Insbesondere kann das Gehäuse an der Radnabe angeordnet sein.The board can be arranged in a wheel-side housing. As a result, the board is protected from external influences. The housing may have a removable lid, which facilitates maintenance. In particular, the housing may be arranged on the wheel hub.

Die Radnabe kann zumindest eine Öffnung aufweisen, die ein Kontaktelement radial durchsetzt, wobei der zugeordnete leitfähige Ring innerhalb der Nabe angeordnet ist. Durch die Öffnung in der Radnabe kann das Kontaktelement geführt und positioniert werden. Wenn der leitfähige Ring innerhalb der Radnabe angeordnet ist, ist er gegen Schmutz und Wasser geschützt. Vorzugsweise ist das Gehäuse im Bereich der Öffnung angeordnet, sodass das Kontaktelement sowohl durch das Gehäuse als auch durch die Radnabe vor Schmutz und Wasser geschützt ist. Dadurch wird eine zuverlässige Übertragung der elektrischen Größe sichergestellt.The wheel hub may have at least one opening that passes radially through a contact element, wherein the associated conductive ring is disposed within the hub. Through the opening in the wheel hub, the contact element can be guided and positioned. If the conductive ring is located inside the wheel hub, it is protected against dirt and water. Preferably, the housing is arranged in the region of the opening, so that the contact element is protected both by the housing and by the wheel hub from dirt and water. This ensures a reliable transmission of the electrical variable.

Weitere Vorteile ergeben sich, wenn die Nabe axial auf der Steckachse fixiert ist. Dadurch wird sichergestellt, dass die leitfähigen Ringe stets dem ihnen zugeordneten Kontaktelement gegenüberliegend angeordnet sind.Further advantages arise when the hub is fixed axially on the thru axle. This ensures that the conductive rings are always arranged opposite the contact element assigned to them.

Besonders vorteilhaft ist es, wenn die Steckachse bei montiertem Rad drehfest angeordnet ist. Dadurch kann sichergestellt werden, dass auch die Übertragungsleitung, die innerhalb der Steckachse verläuft, nicht verdreht wird, sodass eine Beschädigung der Übertragungsleitung verhindert wird. Die Radnabe ist vorzugsweise über ein oder mehrere Lager, insbesondere Kugellager, drehbar auf der Steckachse gelagert.It is particularly advantageous if the plug-in axle is arranged rotationally fixed when the wheel is mounted. This can ensure that even the transmission line that runs within the plug-in axis, is not twisted, so that damage to the transmission line is prevented. The wheel hub is preferably mounted on the axle via one or more bearings, in particular ball bearings.

Die Steckachse weist einen lösbaren Verriegelungsmechanismus auf, wobei der Verriegelungsmechanismus ein gegen eine Rückstellkraft in der Steckachse axial bewegliches Steuerelement aufweist. Über den Verriegelungsmechanismus kann die Steckachse insbesondere in einer Hülse des Fahrzeugkörpers verriegelt werden, sodass das Rad zuverlässig an dem Fahrzeugkörper befestigt ist. Dadurch, dass der Verriegelungsmechanismus ein gegen eine Rückstellkraft bewegliches Steuerelement aufweist, wird sichergestellt, dass ein Verriegelungselement, welches mit dem Steuerelement zusammenwirkt, aufgrund der Rückstellkraft automatisch in eine Verriegelungsstellung bewegt wird.The stub axle has a releasable locking mechanism, wherein the locking mechanism has a against a restoring force in the thru-axle axially movable control. About the locking mechanism, the axle can be locked in particular in a sleeve of the vehicle body, so that the wheel is reliably attached to the vehicle body. Characterized in that the locking mechanism has a movable against a restoring force control, it is ensured that a locking element, which cooperates with the control, is automatically moved due to the restoring force in a locking position.

Vorteilhafterweise weist das Steuerelement zumindest eine Ausnehmung für eine Übertragungsleitung auf. Dadurch kann die Übertragungsleitung an dem Steuerelement bis zum Stecker vorbeigeführt werden. Das Steuerelement ist vorzugsweise drehfest in der Steckachse angeordnet. Somit wird vermieden, dass das Steuerelement die Übertragungsleitung innerhalb der Steckachse verdreht. Überdies wird dadurch sichergestellt, dass die Übertragungsleitung stets in der dafür vorgesehenen Ausnehmung verläuft.Advantageously, the control element has at least one recess for a transmission line. As a result, the transmission line can be guided past the control to the plug. The control is preferably arranged rotationally fixed in the thru-axle. This avoids that the control rotates the transmission line within the plug-in axis. Moreover, this ensures that the transmission line always runs in the recess provided for this purpose.

Das Steuerelement kann zumindest eine Steuerkontur für ein die Verriegelung mit dem Fahrzeug herstellendes Verriegelungselement, insbesondere eine Kugel, aufweisen. Die Steuerkontur ist vorzugsweise so ausgebildet, dass das Verriegelungselement stets geführt wird, unabhängig davon, ob sich das Steuerelement in einer Verriegelungs- oder in einer Freigabeposition befindet. Zu diesem Zweck kann die Steuerkontur zweistufig oder rampenförmig ausgeführt sein. In einer ersten Stufe wird das Verriegelungselement nach außen gedrückt, sodass eine Verriegelungsposition eingenommen wird, in einer zweiten Stufe ist das Verriegelungselement zurückgezogen, sodass das Rad vom Fahrzeugkörper abgenommen werden kann. Vorzugsweise sind zwei gegenüberliegende Kugeln und entsprechend zwei sich am Steuerelement gegenüberliegende Steuerkurven vorgesehen. Dadurch wird die Verriegelung verbessert. Das Steuerelement kann eine zylindrische Grundform aufweisen.The control element can have at least one control contour for a locking element, in particular a ball, which produces the locking with the vehicle. The control contour is preferably designed such that the locking element is always guided, regardless of whether the control element is in a locking or in a release position. For this purpose, the control contour can be two-tiered or run ramped. In a first stage, the locking element is pushed outwards, so that a locking position is assumed, in a second stage, the locking element is retracted, so that the wheel can be removed from the vehicle body. Preferably, two opposing balls and correspondingly two control cams are provided on the control. This improves the lock. The control may have a cylindrical basic shape.

In den Rahmen der Erfindung fällt außerdem ein Rad, insbesondere ein Rollstuhlrad, mit einer erfindungsgemäßen Übertragungsanordnung.In the context of the invention also falls a wheel, in particular a wheelchair wheel, with a transmission arrangement according to the invention.

Außerdem fällt in den Rahmen der Erfindung ein Fahrzeug, insbesondere ein Rollstuhl, mit einer erfindungsgemäßen Übertragungsanordnung.In addition, falls within the scope of the invention, a vehicle, in particular a wheelchair, with a transmission arrangement according to the invention.

Fig. 1 zeigt ein Rollstuhlrad 10 mit einer Felge 11, die Bestandteil eines Laufrads ist, und einem Greifreifen 12. Die Felge 11 und der Greifreifen 12 sind konzentrisch zu einer Nabe 13 angeordnet. Der Greifreifen 12 ist über Verbindungsanordnungen 15 bis 20 mit dem Laufrad, insbesondere der Felge 11, verbunden. Über den Greifreifen 12 kann das Rollstuhlrad 10 manuell durch einen Benutzer angetrieben werden. Die von einem Benutzer an dem Greifreifen 12 eingebrachte Kraft kann durch eine Sensorik, die in eine der Verbindungsanordnungen 15 bis 20 integriert ist, erfasst werden. Entsprechend der eingebrachten Kraft kann ein hier nicht dargestellter (Hilfs-)Antrieb angesteuert werden, um einen Benutzer bei der Fortbewegung des Rollstuhls zu unterstützen. Fig. 1 shows a wheelchair wheel 10 with a rim 11, which is part of an impeller, and a gripping tire 12. The rim 11 and the gripping tire 12 are arranged concentrically to a hub 13. The gripping tire 12 is connected via connecting arrangements 15 to 20 with the impeller, in particular the rim 11. About the grip tire 12, the wheelchair 10 can be manually driven by a user. The force introduced by a user on the grip tire 12 can be detected by a sensor integrated in one of the connection arrangements 15 to 20. According to the introduced force, a (not shown here) (auxiliary) drive can be controlled to assist a user in the movement of the wheelchair.

Die Fig. 2 zeigt eine Übertragungsanordnung 30. Diese umfasst die Radnabe 13 sowie eine Steckachse 31. Die Steckachse 31 durchgreift die Radnabe 13. Die Radnabe 13 ist drehbar auf der Steckachse 31 angeordnet. Die Steckachse 31 kann in eine später noch zu beschreibende Hülse eines Fahrzeugkörpers eingesteckt werden. Dort kann die Steckachse 31 verriegelt werden, indem ein Verriegelungselement durch die Öffnung 32 hindurch in eine entsprechende Aufnahme der fahrzeugkörperseitigen Hülse greift bzw. die Hülse hintergreift. Das Verriegelungselement kann durch die Öffnung 32 zurückgezogen werden, sodass die Steckachse 31 aus der Hülse abgezogen werden kann und somit ein Rollstuhlrad 10 von einem Rollstuhl abgenommen werden kann. Auf der Radnabe 13 sitzt ein Gehäuse 33, welchem ein Kabel über eine Kabelzuführung 34 zugeführt werden kann.The Fig. 2 shows the transmission hub 30. This comprises the wheel hub 13 and a thru-axle 31. The thru-axle 31 passes through the wheel hub 13. The wheel hub 13 is rotatably mounted on the thru-axle 31. The thru-axle 31 can be inserted into a sleeve of a vehicle body to be described later. There, the thru-axle 31 can be locked by a locking element engages through the opening 32 into a corresponding receptacle of the vehicle body side sleeve or engages behind the sleeve. The locking element can be withdrawn through the opening 32, so that the thru axle 31 can be pulled out of the sleeve and thus a wheelchair wheel 10 can be removed from a wheelchair. On the wheel hub 13 sits a housing 33 to which a cable can be fed via a cable feed 34.

Die Fig. 3 zeigt eine Längsschnittdarstellung der Übertragungsanordnung 30 der Fig. 2. Über die Kabelzuführung 34 kann ein hier nicht dargestelltes Kabel dem Gehäuse 33 zugeführt werden und an eine Platine 35 geleitet werden. Auf der Platine 35 kann eine Signalverarbeitung durchgeführt werden. Das über die Kabelzuführung 34 zugeführte Kabel kann sich zu einer radseitigen Einrichtung, beispielsweise einem Signalgeber, erstrecken.The Fig. 3 shows a longitudinal sectional view of the transfer assembly 30 of Fig. 2 , About the cable feed 34, a cable, not shown here, the housing 33 are supplied and passed to a circuit board 35. On the board 35, a signal processing can be performed. The cable supplied via the cable feed 34 may extend to a wheel-side device, for example a signal generator.

Die Platine 35 ist elektrisch leitend mit Kontaktelementen 36, 37 verbunden. Die Kontaktelemente 36, 37 durchragen zum einen das Gehäuse 33 und zum anderen die Radnabe 13. Sie stehen mit in der Radnabe 13 angeordneten elektrisch leitfähigen Ringen 38, 39 in Gleitkontakt. Um einen ständigen Gleitkontakt sicherzustellen, stützen sich die Kontaktelemente 36, 37 über Federelemente 40, 41 an der Platine 35 ab.The circuit board 35 is electrically connected to contact elements 36, 37. The contact elements 36, 37 pass through the housing 33 on the one hand and the wheel hub 13 on the other hand. They are in sliding contact with electrically conductive rings 38, 39 arranged in the wheel hub 13. In order to ensure a permanent sliding contact, the contact elements 36, 37 are supported on the circuit board 35 via spring elements 40, 41.

Die elektrisch leitfähigen Ringe 38, 39 sind auf einer elektrisch isolierenden Hülse 42 angeordnet, die wiederum auf der Steckachse 31 angeordnet ist. Die Hülse 42 weist einen radialen Steg 43 auf, der die elektrisch leitfähigen Ringe 38, 39 in axialer Richtung elektrisch gegeneinander isoliert.The electrically conductive rings 38, 39 are arranged on an electrically insulating sleeve 42, which in turn is arranged on the plug-in axis 31. The sleeve 42 has a radial web 43, which electrically isolates the electrically conductive rings 38, 39 from each other in the axial direction.

Die elektrisch leitfähigen Ringe 38, 39 sind jeweils mit einer Übertragungsleitung 44, 45 elektrisch leitend verbunden. Die Übertragungsleitungen 44, 45 erstrecken sich in der hohlzylindrisch ausgebildeten Steckachse 31 bis zu einem Stecker 46, der ebenfalls in der Steckachse 31 angeordnet ist. Über den Stecker 46 kann ein elektrischer Kontakt zu einem entsprechenden fahrzeugkörperseitigen Stecker hergestellt werden.The electrically conductive rings 38, 39 are each electrically conductively connected to a transmission line 44, 45. The transmission lines 44, 45 extend in the hollow cylindrical plug-in axis 31 to a plug 46, which is also arranged in the plug-in axis 31. Via the plug 46, an electrical contact to a corresponding vehicle body side connector can be made.

Die Hülse 42 und die elektrisch leitfähigen Ringe 38, 39 sind drehfest auf der Steckachse 31 angeordnet. Dadurch kann sichergestellt werden, dass sich die Lage der Übertragungsleitungen 44, 45, die mit den Ringen 38, 39 verbunden sind, im Betrieb nicht ändert.The sleeve 42 and the electrically conductive rings 38, 39 are rotatably mounted on the plug-in axis 31. This can ensure that the position of the transmission lines 44, 45, which are connected to the rings 38, 39, does not change during operation.

Innerhalb der Steckachse 31 erstreckt sich ein Steuerelement 47, welches an einem Ende einen Druckknopf bzw. Aktuator 48 aufweist. Durch Drücken des Aktuators 48 kann ein Verriegelungselement durch die Öffnung 32 zurückgezogen werden.Within the plug-in axis 31, a control 47 extends, which has a push button or actuator 48 at one end. By pressing the actuator 48, a locking element can be withdrawn through the opening 32.

Der Vollständigkeit halber sei erwähnt, dass die Radnabe 13 über Kugellager 49, 50 auf der Steckachse 31 gelagert und relativ zu dieser drehbar angeordnet ist. An der Steckachse 31 sind ringförmige Ausnehmungen 51, 52 vorgesehen, die Sicherungsringe aufnehmen können, um die Radnabe 13 axial auf der Steckachse 31 zu fixieren.For the sake of completeness it should be mentioned that the wheel hub 13 is mounted on ball bearings 49, 50 on the through axle 31 and is arranged rotatable relative thereto. On the thru-axle 31 annular recesses 51, 52 are provided, which can accommodate retaining rings to fix the wheel hub 13 axially on the thru-axle 31.

Die Fig. 4 zeigt eine Schnittdarstellung gemäß der Linie IV-IV der Fig. 3. Die Schnittlinie ist durch den vorderen Teil des Steuerelements 47 gelegt. Hier ist zu erkennen, dass das Steuerelement 47 gegenüberliegende Ausnehmungen 60, 61 für die Übertragungsleitungen 44, 45 aufweist. Weiterhin sind Steuerkonturen 62, 63 vorgesehen, durch welche Verriegelungselemente gesteuert werden.The Fig. 4 shows a sectional view along the line IV-IV of Fig. 3 , The cutting line is laid through the front part of the control 47. Here it can be seen that the control element 47 has opposite recesses 60, 61 for the transmission lines 44, 45. Furthermore, control contours 62, 63 are provided, by which locking elements are controlled.

In der Fig. 5 ist die Übertragungsanordnung 30 mit einer fahrzeugkörperseitigen Hülse 70 gezeigt. Die Hülse 70 ist ortsfest am Fahrzeugkörper, insbesondere Rollstuhlgestell bzw. -rahmen, befestigt. Die Steckachse 31 ist in die Hülse 70 bei montiertem Rad eingesteckt. Aus der Hülse 70 ragt der Anschluss 71 eines fahrzeugkörperseitigen Steckers.In the Fig. 5 For example, the transfer assembly 30 is shown with a vehicle body side sleeve 70. The sleeve 70 is fixed to the vehicle body, in particular wheelchair frame or frame attached. The thru-axle 31 is inserted into the sleeve 70 with the wheel mounted. From the sleeve 70 protrudes the terminal 71 of a vehicle body side connector.

Die Darstellung der Fig. 6 entspricht im Wesentlichen der der Fig. 3 mit dem Unterschied, dass nun auch die Hülse 70 dargestellt ist. Die Hülse 70 weist einen Stecker 72 auf, in den der Stecker 46 eingesteckt ist. Eine elektrische Verbindung zwischen den radseitigen Übertragungsanordnungsteilen und den fahrzeugkörperseitigen Übertragungsanordnungsteilen kann somit einfach durch eine axiale Bewegung der Steckachse 31 erfolgen. Insbesondere wird bei Herstellen der mechanischen Verbindung des Rollstuhlrads mit dem restlichen Rollstuhl automatisch auch eine elektrische Verbindung hergestellt.The presentation of the Fig. 6 is essentially the same as the Fig. 3 with the difference that now also the sleeve 70 is shown. The sleeve 70 has a plug 72, in which the plug 46 is inserted. An electrical connection between the wheel-side transmission arrangement parts and the vehicle body-side transmission arrangement parts can thus be effected simply by an axial movement of the thru-axle 31. In particular, when the mechanical connection of the wheelchair wheel with the rest of the wheelchair is established, an electrical connection is also automatically established.

In der Fig. 7 ist eine Schnittdarstellung gemäß der Fig. VII-VII der Fig. 6 dargestellt. Dabei ist zu erkennen, dass die Hülse 70 sich im Bereich des vorderen Teils des Steuerelements 47 erstreckt, sodass dort eine Verriegelung erfolgen kann.In the Fig. 7 is a sectional view according to the Fig. VII-VII of Fig. 6 shown. It can be seen that the sleeve 70 extends in the region of the front part of the control element 47, so that there can be a lock.

Die Fig. 8 zeigt eine perspektivische Darstellung eines Steuerelements 47'. In der Grundform ist es zylinderförmig. Es weist Ausnehmungen 60, 61 für die Übertragungsleitungen 44, 45 auf. Die Steuerkonturen 62, 63 weisen zwei Stufen 80, 81 auf, die über eine Schräge 82 miteinander verbunden sind. Eine Kugel als Verriegelungselement sitzt in einer verriegelnden Stellung auf der Stufe 80 und in der zurückgezogenen, entriegelten Stellung auf der Stufe 81.The Fig. 8 shows a perspective view of a control element 47 '. In the basic form it is cylindrical. It has recesses 60, 61 for the transmission lines 44, 45. The control contours 62, 63 have two stages 80, 81, which are connected to each other via a slope 82. A ball as a locking element sits in a locking position on the step 80 and in the retracted, unlocked position on the step 81.

Eine Gewindestange kann in das Innengewinde 83 eingeschraubt werden und die Verbindung zu einem Betätigungsmechanismus für den Verriegelungsmechanismus herstellen. Das Steuerelement 47' entspricht dem vorderen Ende des Steuerelements 47.A threaded rod can be screwed into the internal thread 83 and establish the connection to an actuating mechanism for the locking mechanism. The control element 47 'corresponds to the front end of the control element 47.
