Durch diese Konzeption kann der Elektromotor Längs- und Seitenkräfte aufnehmen.in the Frame forms a further embodiment of the invention in a double wishbone suspension of one each Rad associated electric motor part of the lower double wishbone; In this case, the wheel is preferably by means of Beveloidverzahnung driven. Furthermore, an additional handlebar be provided, which is a damping element, for example a spring, which influences the chassis characteristics can be. This concept allows the electric motor to and absorb lateral forces.
Gemäß einer weiteren Ausführungsform der Erfindung kann bei einer Doppelquerlenker-Radaufhängung der Elektromotor einen Teil des Hilfsrahmens bilden und das ihm zugeordnete Rad über ein Planetengetriebe antreiben. Hierbei kann der Elektromotor ein Dämpfelement aufnehmen.According to one Another embodiment of the invention may be in a double wishbone suspension the electric motor form part of the subframe and that to him drive assigned wheel via a planetary gear drive. in this connection the electric motor can absorb a damping element.
Ferner kann der Elektromotor horizontal zwischen den oberen und dem unteren Doppelquerlenker angeordnet und über eine längenänderbare Stange mit dem unteren Doppelquerlenker verbunden sein. Bei dieser Ausführungsform bewegt sich die Stange beim Ein- und Ausfedern des Rades auf einer definierten Bahn, wodurch der Elektromotor in der horizontalen Lage gehalten wird.Further The electric motor can be placed horizontally between the top and the bottom Double wishbones arranged and over a length-adjustable Rod to be connected to the lower double wishbone. At this Embodiment moves the rod during compression and rebound of the wheel on a defined path, causing the electric motor in the horizontal position is maintained.
Für den Fall einer Mehrlenker-Radaufhängung (bei einer derartigen Radaufhängung sind die Lenker aufgelöst), wird erfindungsgemäß vorgeschlagen, dass der Elektromotor eine angelenkte Verlängerung aufweist und als Lenker dient, wobei der Elektromotor zwischen zwei Tragfedern eingespannt ist und wobei die eine Tragfeder mit der Karosserie und die andere Tragfeder mit einem zweiten, unteren Lenker verbunden ist.For the case of a multi-link wheel suspension (in such a Suspension, the handlebars are dissolved), will According to the invention proposed that the electric motor has a hinged extension and serves as a handlebar, wherein the electric motor is clamped between two suspension springs and wherein the one suspension spring with the body and the other suspension spring connected to a second, lower handlebar.
Gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung für den Fall einer Mehrlenker-Radaufhängung wird vorgeschlagen, dass am radseitigen Motorende des Elektromotors ein Gestänge angebracht ist, welches über ein geeignetes Gelenk den Radträger bzw. das Rad führt, wobei der Antrieb des Rades über eine Innenverzahnung der Radnabe oder der Radfelge erfolgt.According to a further advantageous embodiment of the invention in the case of a multi-link wheel suspension is proposed that the Radseitigen motor end of the electric motor, a linkage is mounted, which leads via a suitable joint the wheel or the wheel, the drive of the wheel via an internal toothing of the wheel hub or the wheel rim.
Hierbei kann vorzugsweise vorgesehen sein, dass die Innenverzahnung und das Antriebsritzel der Gelenkkinematik entsprechend ballig ausgeführt sind, wodurch sich trotz eines entstehenden Winkelfehlers beim Einfedern eine gesicherte Momentübertragung zwischen Motor und Rad ergibt.in this connection may preferably be provided that the internal teeth and the drive pinion of the joint kinematics are performed correspondingly spherical, which, despite a resulting angular error during compression a secure torque transfer between engine and wheel results.
