Embodiment Construction

[0030] refer to figure 1 An embodiment of the present invention is explained in detail. The present invention is described herein as an example of a range extender 1 with a rotary piston engine with a rotary piston or a rotor that is triangular in shape. The discs 2, 3 of the rotary piston engine here form a first and a second internal combustion engine respectively and in the figure 1 is shown in such a way that the disks 2 , 3 each rotate in the drawing, so that not only the triangular shape of the rotors 6 , 7 but also the shape of the wobble path of the disks 2 , 3 can be seen.

[0031] The range extender 1 has a first disk 2 of the rotary piston engine and a second disk 3 of the rotary piston engine, which have the same shaft, that is, their rotors 6 , 7 are connected with the same shaft 5 . Here the rotors 6, 7 move planetary around the shaft housing. A shaft 5 connects the two discs 2,3. Between the two disks 2 , 3 of the rotary piston motor, the rotor 10 of the tra...

Abstract

The invention relates to a range extender with two internal combustion engines comprising a first internal combustion engine, a second internal combustion engine, an electro-mechanical energy transducer connected between the first internal combustion engine and the second internal combustion engine, wherein the first internal combustion engine, the second internal combustion engine and the electro-mechanical energy transducer are coupled for power transmission.

Description

technical field [0001] The invention relates to a range extender for a motor vehicle, in particular an electric motor vehicle, which has an internal combustion engine and a transducer for an electric machine. Background technique [0002] The additional equipment usually composed of internal combustion engines in electric vehicles is called a range extender, which drives a generator to supply electrical energy to an energy storage device or an electric motor. [0003] An electric vehicle is a vehicle powered by an electric motor. For its energy supply, storage batteries or battery packs are usually used as energy storage devices, which can be charged either stationary via the public grid or mobile via range extenders or solar modules. [0004] In electric vehicles with a range extender, the internal combustion engine of the range extender is usually started and stopped during driving without direct action from the driver, in particular depending on the state of charge of th...
