Definitions

  • the known gyro and other flywheel drives have a constant moment of inertia. This has an unfavorable effect insofar as a relatively high drive torque, which is dependent on the moment of inertia of the flywheel, is required both when starting off and when increasing speeds that are reduced by power output.
  • the aim of the invention is to eliminate these disadvantages caused by the constant moment of inertia of the flywheel. This is achieved according to the invention by the method with the features of claim 1 and by the device with the features of claim 3.
  • the movable mass parts In the idle state and preferably also at lower speeds, the movable mass parts initially remain near the center. Since the moment of inertia is still small, a smaller drive torque is sufficient. With increasing speed and increasing centrifugal force, the movable mass parts are moved outwards, so that a maximum moment of inertia with a correspondingly increased energy storage capacity of the flywheel mass is established. On the other hand, under load, the deflection of the mass parts decreases with a reduced speed, so that the moment of inertia is also reduced, which in turn means that a lower drive torque is sufficient to increase the speed than would be necessary with a constant maximum moment of inertia.
  • Fig. 2 Flywheel in cross section and floor plan in rotary motion, mass parts enlarge the inertia diameter due to centrifugal force, by swinging out.
  • the mass parts 1 are held at standstill and at a low speed in the center by the pressure and weight of the moving flywheel via the lifting rods, which gives the small inertia diameter. If the flywheel shown in FIG. 1 is now rotated, the mass parts 1 are pulled outwards as a result of the centrifugal force, as shown in FIG.
  • the entire flywheel mass is mounted with two bearings 7, the lower one being additionally provided with an axial bearing.
  • the conventional flywheel has a rigid flywheel mass and a constant inertia diameter
  • the flywheel described according to the invention has a variable flywheel mass and an orbital diameter that can change in itself. This has the advantage that the moment of inertia can be increased or decreased, respectively, by reducing the orbit diameter and, when the optimum speed is reached, the orbit diameter expands again to the maximum.
  • a initially small flywheel with a small wheel circumference Fig. 1 can be rotated about the axis, whereby only a small moment of inertia occurs.
  • the inertia diameter has also increased and the wheel circumference has been created, FIG. 2, the moment of inertia also increasing at the same time.
  • the driving force can be kept small. If the speed drops, the inertia diameter automatically decreases and the drive brings the reduced flywheel mass back to the target speed without an interruption or standstill. This variability in inertia diameter naturally brings quite pregnant centrifugal force, which is stored in kinetic energy in the flywheel.
  • an extended energy consumption can be achieved as a result of energy storage.
  • This prolonged decrease in energy has a particularly favorable effect on an electric driving force, in particular if the drive motor is powered by a battery or a solar generator.

Abstract

L'invention concerne un volant d'inertie comprenant quatre parties massiques (1) qui s'ajustent entre une position d'écartement minimal et une position d'écartement maximal par rapport au pivot (2), sous l'effet de la force centrifuge. Le moment d'inertie de la masse d'inertie varie de ce fait lui aussi entre une valeur minimale et une valeur maximale. Pour les masses d'inertie connues, telles que par exemple le disque d'inertie (5) rotatif déplaçable dans le sens axial, le moment d'inertie est constant et détermine la hauteur du couple d'entraînement requis. Par contre dans ce cas, au moment du démarrage ou pour augmenter une vitesse qui a baissé, le volant d'inertie proposé ne doit surmonter qu'un moment d'inertie réduit, si bien qu'un couple d'entraînement réduit suffit. A contrario, en cas de couple d'entraînement donné, une meilleure capacité d'accumulation est obtenue dans l'effet final. Ce procédé et ce volant d'inertie s'utilisent avant tout dans des commandes électriques, notamment avec une batterie ou un générateur solaire.
