In a motor vehicle, a modular unit including an internal combustion engine with an engine housing and a crankshaft for power take-off, and an electric generator/motor, the generator housing of which is permanently connected to the engine housing, and the rotor of which is coaxially and non-rotationally connected to the crankshaft. According to at least one preferred embodiment of the present invention, the modular unit is characterized by the fact that there is an elastically deformable torque transmission plate which is permanently connected by means of a flange to the driven end of the crankshaft, and is permanently connected on the circumferential side to the rotor, and that the rotor is rotationally mounted in the generator housing.

DETAILED DESCRIPTION The invention teaches that this object can be accomplished for a modular unit in which there is preferably an elastically deformable torque transmission plate which is permanently connected by means of a flange to the driven end of the crankshaft, and is permanently connected on the circumferential side to the rotor, wherein the rotor is preferably rotationally mounted in the generator housing.
Advantageous refinements of the invention are disclosed herebelow.
The above discussed embodiments of the present invention will be described further hereinbelow with reference to the accompanying figures.
When the word "invention" is used in this specification, the word "invention" includes "inventions", that is, the plural of "invention".
By stating "invention", the Applicants do not in any way admit that the present application does not include more than one patentably and non-obviously distinct invention, and maintains that this application may include more than one patentably and non-obviously distinct invention.
The Applicants hereby assert that the disclosure of this application may include more than one invention, and, in the event that there is more than one invention, that these inventions may be patentable and non-obvious one with respect to the other.
In summary, one aspect of the invention resides broadly in a hybrid drive in a motor vehicle, the motor vehicle comprising: a chassis; a plurality of wheels being rotationally mounted on the chassis; motor means for driving the wheels to propel the motor vehicle; the hybrid drive being for powering the motor means of the motor vehicle, and the hybrid drive comprising: generator means for generating power to drive the motor means of the motor vehicle; the generator means comprising a housing and rotor means being rotationally disposed within the housing; internal combustion engine means for powering the generator means; the internal combustion engine means comprising an output shaft for transmitting power from the internal combustion engine means to the generator means; means connecting the output shaft with the generator means to transmit power from the output shaft to the rotor means; the connecting means comprising a disc being connected between the output shaft and the rotor means; and the disc being configured for minimizing, in response to non-rotational displacement of the shaft, non-rotational displacement of the rotor means
