Description
Die Erfindung betrifft ein Transportfahrzeug mit einer Grundplatte, an deren Unterseite zwei baugleiche, steuerbare Achseinheiten angebracht sind, die jeweils ein zentrales Differentialgetriebe und zwei einander gegenüber liegende Einzelradaufhängungen mit Doppelquerlenkern und Scheibenbremsen aufweisen.The invention relates to a transport vehicle with a base plate, on the underside of which two identical, controllable axle units are attached, each having a central differential gear and two mutually opposite independent wheel suspensions with double wishbones and disc brakes.
Derartige Transportfahrzeuge können für vielfältige Anwendungen Verwendung finden, insbesondere als autonom fahrende Fahrzeuge. Es ist möglich, diese als Schwerlastfahrzeuge zum Transport von ISO-Containern zu verwenden. Eine weitere Anwendung ist der Transport von Personenkraftwagen mit Verbrennungsmotoren in Gegenden, in denen eine Fahrt von Fahrzeugen mit Verbrennungsmotoren generell oder mit solchen bestimmter Abgaskategorien behördlich untersagt ist. Solche Personenkraftwagen können mittels Rampen auf ein solches Transportfahrzeug gelangen, welches dann mit dem Personenkraftwagen und dessen Insassen innerhalb dieses ansonsten für das betreffende Fahrzeug gesperrte Gebietes fahren kann. Für ein solches Transportfahrzeug ist eine besonders niedrige Höhe der Grundplatte von Bedeutung, damit das Befahren der Grundplatte mittels einer hochklappbaren Rampe möglichst einfach ist. Noch eine Anwendung sind Lastentransporter für Logistikunternehmen oder der Transport von Personenkabinen.Such transport vehicles can be used for a variety of applications, in particular as autonomously driving vehicles. It is possible to use them as heavy-duty vehicles for the transport of ISO containers. Another application is the transport of passenger cars with internal combustion engines in areas where driving vehicles with internal combustion engines in general or with certain exhaust gas categories is prohibited by the authorities. Such passenger cars can reach such a transport vehicle by means of ramps, which can then drive with the passenger car and its occupants within this area, which is otherwise closed to the vehicle in question. A particularly low height of the base plate is important for such a transport vehicle, so that it is as easy as possible to drive onto the base plate by means of a fold-up ramp. Another application is cargo transporters for logistics companies or the transportation of passenger cabins.
Aus der
Die Aufgabe der Erfindung ist es, ein Transportfahrzeug mit einer möglichst niedrigen Bauhöhe bereitzustellen.The object of the invention is to provide a transport vehicle with the lowest possible height.
Die Erfindung ergibt sich aus den Merkmalen der unabhängigen Ansprüche. Vorteilhafte Weiterbildungen und Ausgestaltungen sind Gegenstand der abhängigen Ansprüche. Weitere Merkmale, Anwendungsmöglichkeiten und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung, sowie der Erläuterung von Ausführungsbeispielen der Erfindung, die in den Figuren dargestellt sind.The invention results from the features of the independent claims. Advantageous further developments and refinements are the subject of the dependent claims. Further features, possible applications and advantages of the invention result from the following description and the explanation of exemplary embodiments of the invention, which are shown in the figures.
Die Aufgabe wird insbesondere dadurch gelöst, dass ein unterer Querlenker jeder Einzelradaufhängung über einen einseitig angelenkten Federlenker mit einer Luftfeder gekoppelt ist und die beiden Scheibenbremsen beidseitig neben dem Differentialgetriebe angeordnet sind. Auf diese Weise ist die Luftfedereinrichtung außerhalb der Doppelquerlenkerachsen angeordnet, was eine besonders niedrige Bauhöhe ermöglicht. In gleicher Weise führt die Verlegung der Scheibenbremsen in den Mittelabschnitt des Fahrzeugs dazu, dass kleinere Räder verwendet werden können und damit ebenfalls die Bauhöhe des Transportfahrzeugs niedrig ausgebildet werden kann.The object is achieved in particular in that a lower wishbone of each independent wheel suspension is coupled to an air spring via a spring link articulated on one side and the two disc brakes are arranged on both sides next to the differential gear. In this way, the air suspension device is arranged outside the double wishbone axles, which enables a particularly low overall height. In the same way, the laying of the disc brakes in the central section of the vehicle means that smaller wheels can be used and thus the overall height of the transport vehicle can also be made low.
Gemäß einer weiteren vorteilhaften Ausbildung der Erfindung erstreckt sich der Federlenker horizontal quer zum unteren Querlenker, wobei dessen Drehgelenk auf einer Seite des Querlenkers angeordnet ist und ein mit der Luftfeder in Wirkverbindung stehendes zweites Ende auf der anderen Seite des Querlenkers liegt. Diese Ausbildung führt dazu, dass die Luftfeder außerhalb des Bauraumes des Querlenkers angeordnet werden kann, wodurch die Bauhöhe der Antriebseinheit und damit des gesamten Transportfahrzeugs niedrig gehalten werden kann.According to a further advantageous embodiment of the invention, the spring link extends horizontally transversely to the lower wishbone, the pivot joint of which is arranged on one side of the wishbone and a second end which is operatively connected to the air spring lies on the other side of the wishbone. This design means that the air spring can be arranged outside the installation space of the wishbone, as a result of which the overall height of the drive unit and thus of the entire transport vehicle can be kept low.
Gemäß einer weiteren vorteilhaften Weiterbildung weist der Federlenker einen U-förmig gekröpften Abschnitt auf, in dem dieser mit dem Querlenker über eine Koppelstange wirkverbunden ist. Auch diese Ausbildung führt zu einer sehr kompakten Verbindung zwischen dem unteren Querlenker und der Luftfeder. Dabei kann der Federlenker so geformt sein, dass sich dieser unterhalb des einen Querlenkerarmes und oberhalb des zweiten Querlenkerarmes erstreckt.According to a further advantageous development, the spring link has a U-shaped cranked section in which it is operatively connected to the transverse link via a coupling rod. This design also leads to a very compact connection between the lower wishbone and the air spring. The spring link can be shaped so that it extends below the one wishbone arm and above the second wishbone arm.
Gemäß einer vorteilhaften Ausbildung der Erfindung ist an der Grundplatte pro Achseinheit ein Tragrahmen für das Differentialgetriebe, die Scheibenbremsen, die Anlenkung der Querlenker und der Federlenker angeordnet. Hierdurch lassen sich die Achseinheiten als einzelne Module leicht anbringen und entfernen, beispielsweise bei Wartungs- oder Reparaturarbeiten.According to an advantageous embodiment of the invention, a support frame for the differential gear, the disc brakes, the linkage of the wishbones and the spring links is arranged on the base plate per axle unit. As a result, the axle units can easily be attached and removed as individual modules, for example for maintenance or repair work.
Gemäß einer weiteren vorteilhaften Ausbildung der Erfindung sind beide Achseinheiten lenkbar. Dadurch lässt sich das Transportfahrzeug mit geringen Kurvenradien fahren, was die Bewegbarkeit erhöht und das Einparken in engen Parklücken erleichtert.According to a further advantageous embodiment of the invention, both axle units can be steered. As a result, the transport vehicle can be driven with small curve radii, which increases mobility and makes parking in tight parking spaces easier.
Gemäß einer vorteilhaften Ausbildung der Erfindung ist zwischen den zwei Achseinheiten vorzugsweise eine elektrische Antriebsmaschine angeordnet, die mittels zwei Antriebsachsen mit den zwei Differentialgetrieben der beiden Achseinheiten gekoppelt ist. Hierdurch lässt sich die Antriebsmaschine leicht warten.According to an advantageous embodiment of the invention, an electric drive machine is preferably arranged between the two axle units and is coupled to the two differential gears of the two axle units by means of two drive axles. This makes the drive machine easy to maintain.
Gemäß einer vorteilhaften Ausbildung der Erfindung umfasst das Transportfahrzeug eine autonome Steuereinheit, und ist beispielsweise mittels üblicher Funktechnologien wie WLAN oder Bluetooth o.ä. ansteuerbar. So kann beispielsweise mittels einer geeigneten Software, vorzugsweise in einem Mobiltelefon, mit der Steuereinheit in Kontakt getreten werden und ein Ziel eingegeben werden, was vom Transportfahrzeug autonom angefahren wird. Dazu umfasst die autonome Steuereinheit eine Navigationssoftware.According to an advantageous embodiment of the invention, the transport vehicle comprises an autonomous control unit and can be used, for example, using conventional radio technologies such as WLAN or Bluetooth or the like. controllable. For example, by means of suitable software, preferably in a mobile phone, the control unit can be contacted and a destination can be entered, which is automatically approached by the transport vehicle. To the autonomous control unit includes navigation software.
