Description

MotorfahrzeugMotor vehicle

Bei Personen- und Lastkraftwagen üblicher Bauart ist die Einzelaufhängung der Räder in vielfacher Weise üblich, wobei konstruktive Unterschiede vor allem in Abhängigkeit davon bestehen, ob die Räder angetrieben und/oder lenkbar sind oder nicht.In passenger cars and trucks of standard design, individual suspension of the wheels is common in many ways, with design differences depending primarily on whether the wheels are driven and/or steerable or not.

Der Gegenstand der Neuerung bezieht sich auf eine Sonderform von Transporter, welche in Österreich und der Schweiz unter der Bezeichnung "Motorkarren" bekannt ist. Charakteristisch für solche Motorkarren ist die Möglichkeit, den die Radfläche tragenden Teil des Fahrgestellrahmens um eine horizontale Längsachse gegenüber dem vorderen Rahmenteil, welcher Antrieb und Fahrerhaus trägt, zu verdrehen. Wenn das Fahrzeug steht, werden bei einer solchen Konstruktion Unebenheiten des Bodens durch gegenseitige Verdrehung des vorderen und hinteren Rahmenteils ausgeglichen.The subject of the innovation relates to a special type of transporter, which is known in Austria and Switzerland as a "motor cart". A characteristic of such motor carts is the ability to rotate the part of the chassis frame that carries the wheel surface around a horizontal longitudinal axis relative to the front frame part, which carries the drive and driver's cab. When the vehicle is stationary, unevenness in the ground is compensated for by mutual rotation of the front and rear frame parts.

Obwohl die Geschwindigkeit von Motorkarren typischerweise niedrig ist, hat sich in der Praxis der Wunsch und damit die Aufgabenstellung ergeben, den Fahrkomfort noch weiter zu erhöhen und eine bessere Anpassung an Geländeunebenheiten zu erzielen. Durch die neuerungsgemäße Kombination der gegeneinander um eine horizontale Achse verdrehbaren Rahmenteile mit einer gefederten Einzelradaufhängung führen Stöße auf eines der Räder somit im wesentlichen nur zu einer Verschwenkung dieses Rades, wogegen es bei langsamen Veränderungen oder Stillstand des Fahrzeuges zu einer Entlastung der Einzelradfederung kommt, da sich der vordere und hintere Rahmenteil des Motorkarrens gegeneinander verdrehen und damit die Unebenheiten des Bodens ausgleichen.Although the speed of motor carts is typically low, in practice the desire and thus the task has arisen to further increase driving comfort and to achieve better adaptation to uneven terrain. Due to the innovative combination of frame parts that can be rotated against each other around a horizontal axis with a sprung independent wheel suspension, impacts on one of the wheels essentially only lead to a swiveling of this wheel, whereas slow changes or when the vehicle is at a standstill relieve the load on the independent wheel suspension, as the front and rear frame parts of the motor cart rotate against each other and thus compensate for the unevenness of the ground.

Bekannte Einzelradaufhängungen, welche nicht nur kurzzeitige Stöße, sondern auch dauernde Unebenheiten des Bodens ausgleichen müssen, haben notwendigerweise einen großen Federweg. Sie sind daher üblicherweise als Parallelogrammlenker ausgeführt. Ist es ausnahmsweise wie beim Puch Haflinger vorgesehen, das Einzelrad starr mit einer einfachen Schwinge zu verbinden, kommt es zu nachteiligen Veränderungen des Radsturzes in Abhängigkeit von der Belastung.Known independent wheel suspensions, which have to compensate not only for short-term impacts but also for permanent unevenness in the ground, necessarily have a large spring travel. They are therefore usually designed as parallelogram links. If, as is the case with the Puch Haflinger, the individual wheel is rigidly connected to a simple swing arm, this leads to disadvantageous changes in the wheel camber depending on the load.

Die Neuerung geht von der Überlegung aus, daß die gefederte Einzelradaufhängung bei einem Motorkarren aufgrund einer eingeschränkten Aufgabenstellung ganz einfach ausgeführt werden kann. Damit wird es überhaupt erst sinnvoll, bei einem Motorkarren eine solche Einzelradaufhängung vorzusehen.The innovation is based on the idea that the sprung independent wheel suspension on a motor cart can be implemented very easily due to a limited task. This is why it makes sense to provide such an independent wheel suspension on a motor cart.

Gemäß einer bevorzugten Ausführungsform ist in an sich bekannter Weise jedes Rad an einer Schwinge gelagert, welche mit dem Rad in der Schwenkebene der Schwinge einen unveränderlichen Winkel einschließt. Die Schwinge kann, wie ebenfalls an sich bekannt. V-förmig und mit dem Rahmenteil durch zwei Drehlager verbunden sein.According to a preferred embodiment, each wheel is mounted on a swing arm in a manner known per se, which forms a fixed angle with the wheel in the swing arm's pivot plane. The swing arm can, as is also known per se, be V-shaped and connected to the frame part by two pivot bearings.

Für gewisse Betriebssituationen ist es günstig, wenn das Rad bzw. die Schwinge über eine hydraulische oder pneumatische Federung am Rahmenteil abgestützt ist, wobei diese Federung durch Druckerhöhung des Fluids blokkierbar ist.For certain operating situations, it is advantageous if the wheel or swing arm is supported on the frame part by a hydraulic or pneumatic suspension, whereby this suspension can be blocked by increasing the pressure of the fluid.

Konstruktive Einzelheiten der Neuerung werden nachstehend anhand der Zeichnungen näher erläutert.Construction details of the innovation are explained in more detail below using the drawings.

Fig. 1 ist eine schematische Draufsicht auf einen Motorkarren, Fig. 2 ein vertikaler Schnitt nach der LinieFig. 1 is a schematic plan view of a motor cart, Fig. 2 is a vertical section along the line

II-II in Fig. 1 und Fig. 3 eine schematische Draufsicht auf den in Fig. 2 ausführlich dargestellten Bereich.II-II in Fig. 1 and Fig. 3 a schematic plan view of the area shown in detail in Fig. 2.

Der Transporter nach Fig. 1 weist zwei Rahmenteile 1, 2 auf, welche gegeneinander um die Achse 3 verdrehbar sind. Neuerungsgemäß sollen zusätzlich die Hinterräder 4 und/oder die Vorderräder 4' einzeln gefedert gelagert sein. Wie schematisch aus Fig. 3 hervorgeht, erfolgt die Lagerung der Räder 4 durch eine über zwei Drehlager 15, 15' mit dem Rahmenteil 2 verbundene Schwinge 5. Am Ende dieser V-förmigen Schwinge befindet sich eine annähernd vertikale Schwenkachse 12, um welche der Radkopf 6 mittels des Lenkzylinders 17 verschwenkbar ist.The transporter according to Fig. 1 has two frame parts 1, 2, which can be rotated relative to one another about the axis 3. According to the innovation, the rear wheels 4 and/or the front wheels 4' are also to be individually spring-mounted. As can be seen schematically in Fig. 3, the wheels 4 are mounted by a swing arm 5 connected to the frame part 2 via two pivot bearings 15, 15'. At the end of this V-shaped swing arm there is an approximately vertical pivot axis 12, about which the wheel head 6 can be pivoted by means of the steering cylinder 17.

Weitere Details dieser Anordnung ergeben sich aus Fig. 2. Aus Fig. 2 ist insbesondere die Anordnung der Antriebswelle 8 ersichtlich, welche die Verbindung zwischen dem Differential 16 und dem Rad 4 vermittelt. Die oberhalb der Schwinge 5 angeordnete Antriebswelle 8 weist beidseits Gelenke 9, 10 auf, von welchen mindestens eines, im dargestellten Fall das Gelenk 10, eine Längsverschiebung der Antriebswelle 8 erlaubt, wenn sich der Winkel zwischen Antriebswelle 8 und Schwinge verdreht. Über das Gelenk 9 erfolgt der Antrieb des am Radkopf 6 angeordneten Planetengetriebes 7, welches die Drehgeschwindigkeit der Antriebswelle 8 auf das Rad 4 untersetzt. Der Radkopf 6 ist um die Schwinge 5 mit der Schwenkachse 12 schwenkbar, in der Zeichenebene jedoch starr mit dieser verbunden.Further details of this arrangement can be seen in Fig. 2. In particular, Fig. 2 shows the arrangement of the drive shaft 8, which provides the connection between the differential 16 and the wheel 4. The drive shaft 8, which is arranged above the swing arm 5, has joints 9, 10 on both sides, of which at least one, in the case shown the joint 10, allows a longitudinal displacement of the drive shaft 8 when the angle between the drive shaft 8 and the swing arm changes. The joint 9 drives the planetary gear 7 arranged on the wheel head 6, which reduces the rotational speed of the drive shaft 8 to the wheel 4. The wheel head 6 can be pivoted about the swing arm 5 with the pivot axis 12, but is rigidly connected to it in the plane of the drawing.

Die Schwinge 5 ist über eine hydraulische oder pneumatische Federung 11 am Rahmenteil 2 abgestützt. Die Schwenkbewegung der Schwinge 5 um die Drehlager 15, 15' wird durch diese hydraulische oder pneumatische Federung 11 gedämpft bzw. durch Blockieren der Federung 11 (durch Druckerhöhung des Fluids) unterbunden.The swing arm 5 is supported on the frame part 2 via a hydraulic or pneumatic suspension 11. The pivoting movement of the swing arm 5 around the pivot bearings 15, 15' is dampened by this hydraulic or pneumatic suspension 11 or prevented by blocking the suspension 11 (by increasing the pressure of the fluid).

Die Bremsung des Rades 4 erfolgt vorzugsweise im Bereich niedrigen Drehmoments, also hoher Drehgeschwindigkeit praktisch auf der Differentialseite. Hiezu ist am starren Abtrieb 16 des Differentials eine Bremsscheibe 13 angeordnet, welche über Bremsbacken 14 abgebremst werden kann.Braking of wheel 4 preferably takes place in the range of low torque, i.e. high rotational speed, practically on the differential side. For this purpose, a brake disk 13 is arranged on the rigid output 16 of the differential, which can be braked via brake shoes 14.
