Das Stirnradgetriebe und eine Radlagerung zur Lagerung der Radnabe sind innerhalb des Getriebegehäuses angeordnet. Der Elektromotor weist eine Drehachse auf, um welche sich seine Antriebswelle dreht, und die Radnabe weist eine Drehachse auf, um welche diese drehbar gelagert ist. Das Gehäuse weist Mittel zum Verbinden des Gehäuses mit dem Fahrzeugchassis auf, wobei diese Mittel symmetrisch um eine Ebene angeordnet sind, um welche sich einerseits die Drehachse des Elektromotors und andererseits die Drehachse der Radnabe schneidet. Diese Mittel zum Verbinden sind außerhalb des Elektromotors angeordnet, wodurch es möglich ist, den Elektromotor schon direkt mit dem Gehäuse zu verbinden und anschließend den gesamten Antrieb mit Elektromotor im Fahrzeug einzubauen. Durch die Symmetrie der Mittel zum Verbinden des Gehäuses mit dem Fahrzeugchassis ist es möglich, einen Antrieb einer ersten Fahrzeugseite auch auf der gegenüberliegenden Fahrzeugseite ohne Veränderung des Fahrzeugchassis zu verwenden. Das Gehäuse besteht vorzugsweise aus einem Gehäusedeckel, an welchem der Elektromotor befestigt ist, und aus einem weiteren Gehäuseteil, in welchem die Radlagerung angeordnet ist, wobei beide Gehäuseteile Mittel zum Verbinden mit dem Fahrzeugchassis aufweisen. Vorzugsweise sind diese Mittel so ausgestaltet, dass sie als zylinderförmige Anformungen am Gehäuse, insbesondere am Gehäusedeckel, und dem weiteren Gehäuseteil angeformt sind und einen zentrischen Durchbruch aufweisen, welcher es ermöglicht, mittels Schrauben den Gehäusedeckel mit dem weiteren Gehäuseteil und gleichzeitig das Gehäuse mit dem Fahrzeugchassis zu verbinden.According to the invention the electric wheel drive on an electric motor, which over a spur gear a wheel hub for driving the vehicle wheel, especially an industrial truck, drives. The spur gear and a wheel bearing for supporting the hub are inside the gearbox arranged. The electric motor has an axis of rotation about which its drive shaft rotates, and the wheel hub has an axis of rotation on which it is rotatably mounted. The housing has means for connecting the housing to the vehicle chassis on, wherein these means are arranged symmetrically about a plane, which on the one hand, the axis of rotation of the electric motor and on the other the axis of rotation of the wheel hub cuts. These means of connection are arranged outside the electric motor, making it possible is to connect the electric motor directly to the housing and then the entire drive with electric motor to be installed in the vehicle. Due to the symmetry of the means of connection of the housing with the vehicle chassis it is possible a drive of a first side of the vehicle on the opposite side Vehicle side without changing the vehicle chassis to use. The housing preferably consists of a housing cover, to which the electric motor is attached, and from another Housing part, in which the wheel bearing is arranged, wherein both housing parts means for connecting to the vehicle chassis exhibit. Preferably, these means are designed such that they as cylindrical formations on the housing, in particular on the housing cover, and the further housing part are formed and have a central breakthrough, which it allows, by means of screws the housing cover with the other housing part and at the same time the housing to connect with the vehicle chassis.

In einer weiteren Ausgestaltungsform der Erfindung ist das weitere Gehäuseteil so ausgeformt, dass es einerseits die Form des Gehäusedeckels aufweist, und somit zur Aufnahme des Stirnradgetriebes ausgebildet ist, und andererseits eine zylinderförmige Erstreckung aufweist, in welcher die Radlagerung angeordnet ist.In Another embodiment of the invention is the further Housing part formed so that it on the one hand the shape having the housing cover, and thus for receiving the Spur gear is formed, and on the other hand, a cylindrical Has extension in which the wheel bearing is arranged.

Die Mittel zum Verbinden 9 sind symmetrisch zu einer Ebene, welche durch die Drehachse 6 und die Drehachse 7 geht, angeordnet, wodurch es möglich ist, den elektrischen Antrieb sowohl auf der rechten als auch auf der linken Fahrzeugseite zu verwenden. Vorzugsweise sind auch die Befestigungen des Elektromotors 11 symmetrisch aufgebaut, was es ermöglicht, die Anschlüsse des Elektromotors auf der gleichen Seite zu haben. Eine Entlüftung 12 ist mittig am Gehäuse 1 angeordnet, so dass das Gehäuse in beidseitiger Lage sicher entlüftet werden kann. Die Befüllung des elektrischen Antriebs mit Schmiermittel erfolgt durch die Befüllung 13.The single FIGURE each shows an electric drive for a right and a left vehicle wheel of a truck, wherein the drive is a housing 1 in which a not-shown spur gear and a bearing not shown for a hub 2 are arranged, and an electric motor 3 having, which with the housing cover 4 connected is. The electric motor has a drive shaft 5 on which is a rotation axis 6 rotates. The wheel hub 2 turns around a rotation axis 7 , The housing 1 consists of the housing cover 4 and another housing part 8th , The housing 1 has means for connection 9 on, which are formed as cylindrical projections on the housing and a central opening 10 exhibit. The means of connection 9 are on the one hand in the housing cover 4 and on the other hand in the other housing part 8th formed, whereby it is possible by means of a screw sowoh the housing cover 4 with the other housing part 8th as well as to connect the entire housing with a vehicle chassis, not shown. The means of connection 9 are symmetrical to a plane passing through the axis of rotation 6 and the rotation axis 7 is arranged, whereby it is possible to use the electric drive on both the right and on the left side of the vehicle. Preferably, the fasteners of the electric motor are 11 symmetrically constructed, which makes it possible to have the connections of the electric motor on the same side. A vent 12 is centered on the housing 1 arranged so that the housing can be safely vented in two-sided position. The filling of the electric drive with lubricant is carried out by the filling 13 ,
