Drive train of a solely electrically driven motor vehicle having two electric motors

摘要

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.

主权项

1. A drive train of a solely electrically drivable motor vehicle, comprising:
an axle with first and second axle sections for driving first and second wheels respectively, a differential having an input gear and first and second outputs connected respectively to the first and second axle sections, first and second electric machines interacting respectively with first and second gearings, a first switchable clutch selectively connecting the first gearing to the input gear of the differential for driving first and second axle sections of the axle, second clutch selectively connecting the first gearing to the first axle section of the axle, and a third clutch selectively connecting the second gearing to the second axle section of the axle, wherein the first electric machine drives the first and second axle sections in and energy saving mode when the first switchable clutch is closed, the second and third clutches are open and the second electric machine is switched off, and wherein the first and second electric machines independently drive the respective first and second axle sections when the second and third clutches are closed and the first clutch is open.
