Drive train of a purely electrically all-wheel drivable motor vehicle
First Claim
1. A drive train of a purely electrically all-wheel drivable motor vehicle, comprising a first axle and a second axle spaced apart along a direction of travel of the motor vehicle, and two electric machines arranged laterally of one another and each having a driven shaft aligned in the direction of travel of the motor vehicle, the two electric machines further being disposed so that the first axle is between the second axle and the electric machines, the first axle being drivable by the electric machines via a gearing, the gearing having a first shaft that is drivable by the two electric machines, a first spur gear and at least one bevel gear toothing being connected to the first shaft, the gearing and the first axle being connected to each other by the at least one bevel gear toothing, and the gearing and a second shaft for driving the second axle being connected to each other by the first spur gear on the first shaft meshing with a second spur gear on the second shaft.

Abstract
A drive train (1) of a purely electrically all-wheel drivable motor vehicle, has a first axle (2), a second axle and two electric machines (10) arranged in the direction of travel (3) of the motor vehicle. The first axle (2) can be driven by the electric machines (10) via a transmission (11). The transmission (11) and the first axle (2) are connected to each other by at least one bevel gear toothing (20, 7; 20, 27), and the transmission (11) and a shaft for driving the second axle are connected to each other by at least a further toothing (22, 23; 22, 28). In this way, an all-wheel drive can be achieved with a simple construction by the use of such a drive train in a motor vehicle that is to be operated in a purely electrical manner.
