Definitions

• the invention relates to a drive device for motor vehicles with a control device feedable ble electric drive motor for at least one driving tool wheel and a flywheel serving as an energy storage device, in which during a braking process by means of the generator acting as a wheel drive motor and a flywheel motor, energy for later use can be stored as drive energy.
• the motor driving the flywheel when braking is used as a generator when energy is removed from the flywheel and the energy subsequently extracted from the flywheel can either be supplied to the wheel drive motor or in electric trains the contact wire line can be fed back.
• the invention in contrast, is concerned with the task of creating a drive device of the type specified in the introduction which is suitable for motor vehicles with an internal combustion engine (Otto or Disel engine) and which enables the internal combustion engine to be dimensioned so weakly as to save fuel that it essentially only the energy required to overcome the driving resistance (rolling and air resistance) and to cover the losses in the drive device when driving at a uniform speed in the plane, but can be long can run continuously at optimal speed, and to make the arrangement so that in the event of acceleration and when driving uphill, the required increased energy is to a large extent covered by the energy stored in the flywheel during braking, without switching the drive device from energy consumption of the internal combustion engine would be required on the flywheel energy consumption.
• This object is achieved in that the flywheel motor with the flywheel and this with a flywheel generator are mechanically in constant drive connection, that for the electrical energy supply of the flywheel motor a feed generator driven by an internal combustion engine, preferably in
• the flywheel generator is connected to the wheel drive motor via a control device and that the wheel drive motor acting as a generator is used to brake the vehicle via the control device and changeover switch while simultaneously interrupting its feed connection to the flywheel generator instead of the feed generator to the Flywheel motor can be switched on.
• the internal combustion engine normally drives the flywheel motor via the feed generator, which in turn, possibly via a transmission gear, drives the flywheel in such a way that, when traveling in the plane at a uniform speed, essentially the entire energy requirement covers the wheel drive motor so that the energy stored in the flywheel remains essentially unchanged.
• a buffer battery is preferably seen from which, if necessary, relatively high electrical energy for flywheel drive can be removed for a short time, so that the total energy available briefly for acceleration is still significantly above the maximum storage energy of the flywheel.
• the buffer battery can then be gradually recharged via the feed generator driven by the internal combustion engine. If the flywheel reaches a predetermined maximum speed after storage of the braking energy after a long descent, the internal combustion engine is advantageously switched off by a control device; after the speed has dropped to a likewise predetermined value, the internal combustion engine can be automatically switched on again using known means.
• FIG. 1 shows schematically the overall structure of a drive device according to the invention
• Figs. 2 and 3 also schematically, in mutually perpendicular, partially sectioned views represent an advantageous embodiment of an integral structural unit comprising the flywheel motor, the flywheel and the flywheel generator.
• Pig. 1 is a relatively small gasoline or diesel engine 1, for example with 10 KW, connected via a rigid shaft 2 to an electric generator 3, referred to briefly as a feed generator, which operates in a buffer operation, indicated only schematically, with an accumulator battery 4 and, like this, in FIG Position a of a first switch 11 electrically feeds a flywheel motor 5.
• the rotor of the flywheel motor 5 is connected to a flywheel 7 via a rigid shaft 6 or a transmission gear, which in turn is connected to the rotor of a flywheel generator 9 via a rigid shaft 8 or a transmission gear.
• the output voltage of the flywheel generator 9 is applied to a wheel drive motor 15 in the position a of a second changeover switch 12 via a control device 10 used to control the energy supply, which drives two wheels 15 of the motor vehicle via shafts 14 in the exemplary embodiment shown.
• a control device 10 used to control the energy supply, which drives two wheels 15 of the motor vehicle via shafts 14 in the exemplary embodiment shown.
• the wheel drive motor 13 which now acts as a generator, is connected to the flywheel motor 5 via the control device 10.
• the drive device described works as follows:
• the internal combustion engine 1 essentially runs continuously at the optimal speed.
• To switch 11, 12 in position a is in the
• the flywheel generator 9 drives the wheel drive motor 13 via the appropriately similar loan as the gas and brake pedals of motor vehicles with direct internal combustion engine drive control device 10.
• a significant proportion of the energy supplied to the wheel drive motor 13 is taken from the flywheel 7, while otherwise the energy requirement of this motor is essentially covered by the internal combustion engine 1 via the electromechanical drive chain containing the flywheel motor 5, the flywheel 7 and the flywheel generator 9.
• Flywheel 7 accelerates so that a significant part of the braking energy is stored in the flywheel. The greater the 3-rated voltage ratio of the two motors
• an automatic control device for example in the form of a centrifugal switch with two
• Circuits that are in Pig. 1 e.g. sits on the drive shaft 6 of the flywheel 7 and via a control line
• the engine 1 can be switched off when a predetermined maximum speed of the flywheel 7 is reached and can only be switched on again when this speed drops to a predetermined minimum value, so that in the meantime the entire energy requirement is covered by the flywheel 7.
• the control device 10 preferably contains thyristor or transistor circuits which chop up the respectively applied DC voltage and each supply the motor 13 or 5 with a variable mean DC voltage.
• Electric motors 13 and 5 are advantageously used disc rotor motors that work on the principle of the Barlow wheel, the flywheel generator 9 can have the same structure as the motors.
• the transition from acceleration to braking is advantageously controlled by a microprocessor because the pulse duty factor of the pulsating voltage must be changed very quickly. It is also possible instead a drive motor common to all wheels to use a separate motor for each wheel, in particular a disc rotor motor.
• a microprocessor can then control the speed of the individual motors so that cornering without a differential is possible and that spinning or locking of one or more wheels is largely prevented.
• a further advantageous embodiment of the invention results if, according to FIGS. 2 and 3, in an integral structural unit formed from a flywheel motor, flywheel and flywheel generator, the flywheel 7 is a disk 20 made of magnetic material, in particular a magnetized magnet, according to arrow 21 in FIG. 3 Ferrite is formed, which also forms a common anchor for the flywheel motor and the flywheel generator.
• the flywheel motor 5 and the flywheel generator 9 can have stepping winding windings 22, 23 which are uniformly distributed over the circumference of the disk 20 and lie in a common plane 24-24, but are equally angularly offset from one another. In this way, a very compact and space-saving unit is obtained, whereby of course appropriately trained control devices must be assigned to the motors.
