Abstract
(DE)
Antriebsachse eines Elektrofahrzeuges mit einem ersten und einem zweiten Antriebsrad (R1, R2) mit Radachsen (a1, a2), einer ersten elektrischen Maschine (EM1) und einer zweiten elektrischen Maschine (EM2) mit einer gemeinsamen Rotationsachse (m), einem Schaltgetriebe (G3) mit einer Getriebeeingangswelle (EW) und einer Getriebeausgangswelle (AW) sowie einem Achsdifferenzial (Dl) mit einem Differenzialeingang (DIK) und zwei Differentialausgangswellen (3a, 3b), wobei die erste elektrische Maschine (EM1) mit der Getriebeeingangswelle (EW) und die Getriebeausgangswelle (AW) mit dem Differenzialeingang (DIK) verbunden sind und wobei die zweite elektrische Maschine (EM2) bedarfsweise als zusätzlicher Antrieb zuschaltbar ist.
(EN)
The invention relates to a drive axle of an electric vehicle with a first and a second drive wheel (R1, R2) with wheel axles (a1, a2), a first electric machine (EM1) and a second electric machine (EM2) with a common rotational axis (m), a manual transmission (G3) with a transmission input shaft (EW) and a transmission output shaft (AW) as well as an axle differential (DI) with a differential input (DIK) and two differential output shafts (3a, 3b), wherein the first electric machine (EM1) is connected to the transmission input shaft (EW), the transmission output shaft (AW) is connected to the differential input (DIK), and the second electric machine (EM2) can be switched on as an additional drive if necessary.
