Abstract

A motor vehicle (10) has a drive train in the region of a front axle. A body of the motor vehicle has connection points (1, 2, 3) for a laterally arranged internal combustion engine, a vehicle transmission (15) and a torque plate of a motor vehicle (10) that can be driven exclusively by the internal combustion engine. The connection points (1, 2, 3) also are connection points for a hybrid drive train (11). The vehicle uses a modular design principle and can be equipped with differently designed drive systems, including conventional drive exclusively by an internal combustion engine and hybrid drive, without having to make structural modifications. The hybrid drive train may be a serial hybrid or a parallel hybrid.

Claims

1. A motor vehicle having a drive train in a region of a vehicle axle, a body of the motor vehicle having connection points for the drive train, the connection points providing connection for a laterally arranged internal combustion engine, a vehicle transmission and a torque plate of the motor vehicle that can be driven exclusively by the internal combustion engine, characterized in that these connection points also are connection points for a hybrid drive train.

2. The motor vehicle of claim 1, wherein the hybrid drive train has a serial hybrid.

3. The motor vehicle of claim 2, wherein the serial hybrid has the internal combustion engine, a generator, an electric traction motor and a transmission, with mechanical coupling of these components and torque decoupling between the internal combustion engine and the generator, and between the electric motor and the generator.

4. The motor vehicle of claim 1, wherein the hybrid drive train has a parallel hybrid.

5. The motor vehicle of claim 4, wherein the parallel hybrid has an internal combustion engine, an electric traction motor and a transmission, with mechanical coupling and torque coupling of the internal combustion engine, the electric traction motor and the transmission.

6. The motor vehicle of claim 5, wherein the parallel hybrid has an electrical machine that can be operated as the electric traction motor and as a generator.

7. The motor vehicle of claim 1, characterized in that the transmission has a spur gear stage with two cardan shafts arranged in front of or behind the internal combustion engine relative to a direction of travel of the motor vehicle and are connected to the transmission, for driving the wheels of a vehicle axle of the vehicle.

8. A plurality of motor vehicles having substantially identical bodies and substantially identical connection points on the respective bodies, each of the motor vehicles further having a drive train supported on the connection points, the drive train of at least one of the vehicles being a conventional drive train with a laterally arranged internal combustion engine, a vehicle transmission and a torque plate of the motor vehicle that can be driven exclusively by the internal combustion engine, the drive train of at least a second of the motor vehicles being a hybrid drive train.

9. The plurality of motor vehicles of claim 8, wherein the hybrid drive train has a serial hybrid.

10. The plurality of motor vehicles of claim 9, wherein the serial hybrid has the internal combustion engine, a generator, an electric traction motor and a transmission, with mechanical coupling of these components and torque decoupling between the internal combustion engine and the generator, and between the electric motor and the generator.

11. The plurality of motor vehicles of claim 10, wherein a first of the connection points is between the drive train and a longitudinal member on a right side of the vehicle body relative to a forward direction of travel and in a region of the internal combustion engine, a second of the connection points is between the drive train and a longitudinal member on a left side of the vehicle body relative to the forward direction of travel and in a region of the electric motor and a third of the connection point is formed by a crossmember that connects the longitudinal members.

12. The plurality of motor vehicles of claim 11, wherein the third connection point is behind the transmission and is connected to the transmission.

13. The plurality of motor vehicles of claim 12, wherein the first and second connection points are disposed and configured to support the weight of the drive train and the third connection point is disposed and configured to receive the torque introduced into the vehicle body via the drive train and thereby functions as a torque plate

14. The plurality of motor vehicles of claim 8, wherein the hybrid drive train has a parallel hybrid.

15. The plurality of motor vehicles of claim 14, wherein the parallel hybrid has an internal combustion engine, an electric traction motor and a transmission, with mechanical coupling and torque coupling of the internal combustion engine, the electric traction motor and the transmission.

16. The plurality motor vehicles of claim 15, wherein the parallel hybrid has an electrical machine that can be operated as the electric traction motor and as a generator.
