Abstract
A drive train (6) is provided for a motor vehicle which can be driven in a purely electric manner. A gear mechanism (7, 15) has a standardized housing (8) for accommodating an electrical machine (16) or two electrical machines (10, 11) and for accommodating two gear mechanism output shafts (9) which are associated with a vehicle axle (2, 4). A large number of drive topologies for various vehicle sectors with purely electric drives can be formed by configuring the drive train in this way.
Claims14
A drive train of a motor vehicle that can be driven in a purely electric manner, the motor vehicle having a front axle and a rear axle and opposite first and second lateral sides, the drive train comprising:
- a front gear mechanism having a front housing, a front electrical machine located between the front and rear axles and being flange mounted to the front housing at a position between the front housing and the first lateral side of the motor vehicle, no electrical machine being mounted to the front housing at a position between the front housing and the second lateral side of the motor vehicle, and two front gear mechanism output shafts extending from the front housing and associated with the front axle;
- and
- a rear gear mechanism having a rear housing, a rear electrical machine located between the front and rear axles and being flange mounted to the rear housing at a position between the rear housing and the second lateral side of the motor vehicle, no electrical machine being mounted to the rear housing at a position between the rear housing and the first lateral side of the motor vehicle, and two rear gear mechanism output shafts extending from the rear housing and associated with the rear axle,
- wherein the front housing and the rear housing are identical but are reversed relative to one another in a front-rear direction,
- wherein a size of the front electrical machine is different from a size of the rear electrical machine, and
- wherein a first of the electrical machines is an asynchronous machine and a second of the electrical machines is a permanent-magnet synchronous machine.
