Abstract
A drive train (1) of a solely electrically driven motor has an axle (2) with first and second axle sections (4, 5) connected to different outputs of a differential (35). The drive train also has a first and second electric motors (13, 14) that co-operate with first and second transmissions (15) respectively to drive the axle (2). A first clutch can connect the first transmission (15) to an entry wheel (34) of the differential (35) for driving the two axle sections (4, 5) of the axle (2). A second clutch (37) can connect the first transmission (15) to the first axle section (4) while the first clutch (36) is open and a third clutch (38) can connect the second transmission (16) to a second axle section (5) while the first clutch (36) is open.
