Description
Fahrgestell mit unabhängig voneinander auf- und abbeweglichen und durch je einen Elektromotor angetriebenen Rädern, insbesondere für Trolleybusse. Die Erfindung bezieht sich auf ein Fahr gestell mit unabhängig voneinander auf- und abbeweglichen und durch je einen Elektromotor angetriebenen Rädern, ins besondere für Trolleybusse. Bei derartigen Fahrgestellen sind die Räder auf quer zur Fahrtrichtung verlaufenden Pendelhalb- aehsen angeordnet, auf welchen der An triebsmotor gelagert ist.
Gemäss der Erfindung ist der Elektro motor an demselben Ende der Halbachse, wie das von ihm angetriebene Laufrad ange ordnet und von dem glockenartigen, nach aussen offenen Radkörper umgeben.
Das erfindungsgemässe Fahrgestell hat den Vorteil, dass. der Elektromotor nach aussen abmontiert werden kann, ohne das Rad wegnehmen zu müssen. Ausserdem kann die Halbachse innerhalb des Rades zwecks Tieflegung der Anlenkungsstelle ab gekröpft sein. Infolge des Umstandes, dass der Elektromotor, wie das Rad, ausserhalb der Karosserie in einem für das Rad ohne hin vorgesehenen Raum zu liegen kommt, kann der Boden der Karosserie tiefer ver legt und die Karosserie geräumiger gestaltet werden als bei Fahrzeugen mit unter der Karosserie liegenden Antriebsmotoren.
In der Zeichnung ist der Erfindungs gegenstand in einem Ausführungsbeispiel dargestellt. Die Figur ist ein quer zur Längsrichtung des Fahrgestelles verlaufen der, schematischer Schnitt durch eine Pendel halbachse nebst Motor und zugehörigem Rad.
Die entweder gerade verlaufende, oder wie strichpunktiert angedeutet gekröpfte Halbachse 1, ist bei 2 an den mittleren Rahmenteil 3 des Fahrgestelles angelenkt. Die Halbachse ist hohl ausgebildet, so dass sie zur Unterbringung der zum Elektromotor führenden Stromleiter dient. Am äussern Ende der Halbachse ist der Stator 4 fest und der den Stator umgebende Rotor 5 des Elektromotors drehbar gelagert. Ein mit dem Rotor 5 auf der der Fahrzeugmitte zu gewendeten Seite fest verbundenes Ritzel 6 überträgt unter Vermittlung von Zahnrädern 7 mit feststehender Achse seine Bewegung auf einen Zahnkranz B.
Der Zahnkranz 8 ist an dem auf der Achse 1 drehbar gelager ten ;glockenartigen Radkörper 9 vorhanden. Der nach aussen offene Radkörper 9 weist an der Innenseite eine Bremstrommel 10 auf, an der in üblicher Weise Bremsbacken 11, die von einer mit der Halbachse 1 fest ver bundenen Scheibe 12 getragen werden, zur Anlage kommen können. Der Radkörper 9 ist- durch einen Deckel 13 abgeschlossen, der zum Zwecke des Nachsehens, der Reparatur oder der völligen Herausnahme des Elektro motors abnehmbar ist. An Stelle der Felge 14 für einfache Bereifung kann auf dem Radkörper auch eine Felge für doppelte Bereifung angeordnet sein.
Chassis with wheels that can be moved up and down independently of one another and each driven by an electric motor, especially for trolley buses. The invention relates to a chassis with independently moved up and down and each driven by an electric motor wheels, in particular for trolley buses. In chassis of this type, the wheels are arranged on pendulum half-axles which run transversely to the direction of travel and on which the drive motor is mounted.
According to the invention, the electric motor is arranged at the same end of the semiaxis as the impeller driven by it and is surrounded by the bell-like, outwardly open wheel body.
The chassis according to the invention has the advantage that the electric motor can be removed from the outside without having to remove the wheel. In addition, the semi-axis can be cranked within the wheel for the purpose of lowering the articulation point. As a result of the fact that the electric motor, like the wheel, comes to lie outside the body in a space that is not provided for the wheel, the floor of the body can be laid deeper and the body can be made more spacious than in vehicles with under the body Drive motors.
In the drawing, the subject invention is shown in one embodiment. The figure is a transverse to the longitudinal direction of the chassis, a schematic section through a pendulum semi-axis together with the motor and associated wheel.
The semi-axis 1, which either runs straight or is cranked as indicated by dash-dotted lines, is articulated at 2 to the central frame part 3 of the chassis. The semi-axis is hollow so that it is used to accommodate the current conductors leading to the electric motor. At the outer end of the semi-axis, the stator 4 is fixed and the rotor 5 of the electric motor surrounding the stator is rotatably mounted. A pinion 6 that is firmly connected to the rotor 5 on the side facing the center of the vehicle transmits its movement to a toothed ring B through the intermediary of gears 7 with a fixed axis.
The ring gear 8 is provided on the bell-shaped wheel body 9 rotatably mounted on the axle 1. The outwardly open wheel body 9 has on the inside a brake drum 10, on which in the usual manner brake shoes 11, which are carried by a disc 12 firmly connected to the semi-axis 1, can come to rest. The wheel body 9 is closed by a cover 13, which can be removed for the purpose of looking, repairing or completely removing the electric motor. Instead of the rim 14 for single tires, a rim for double tires can also be arranged on the wheel body.
