  • examination methods are increasingly used, in which not only sta tables, but also dynamic values can be determined under load.
  • the dynamic values play an important role in prophylactic, rehabilitation, general, sports and occupational medicine diagnostics.
  • the stress is expediently created by cycling, which places the same strain on old and young people, or on practiced and inexperienced patients. The cycling continues in a lying and standing body position.
  • variable stress variable stress, harmless, can be terminated as desired, should be physiological and reproducible.
  • Feedback is a particular advantage if the load system can be controlled by the functional parameters / breathing, ECG, blood pressure etc./
  • the following technical solutions were used to produce loads: eddy current braking, electric motor in braking mode, the Dynamo system Motor tachometer, scale motor, mechanical braking, etc.
  • the disadvantages of the variants listed are: the robust construction, high manufacturing costs, high basic friction, forced systems due to the characteristics of rotary machines, high power consumption, speed-dependent load.
  • the KE 21 device sold by the MEDICOR works, which is driven by a pedal drive by means of a freewheel, a flywheel, or ultimately an electric motor of a special design in braking mode.
  • the electric motor is connected to external control or load circuits, which can be used to set the desired load or to compensate for the internal friction, which is around 40 - 50 W.
  • the previously known devices are - although they do their basic job - disadvantageous from the point of view that the weight is too great, which makes handling or transport more difficult, complex solutions are necessary to compensate for the internal friction, the accuracy of which is not is always sufficient.
  • the invention has for its object to create such a physiological load unit that has a small internal friction with a simple design.
  • the physiological load unit according to the invention has a freewheeling shaft driven by the person to be examined, a step-up gear, a flywheel mass which is coupled to the acceleration side of the step-up gear or to an electric motor in braking mode. External electrical control and load circuits are connected to the electric motor. Furthermore, the drive shaft according to the invention is connected via a freewheel to a disc wheel with internal teeth, the inside of which has several intermediate wheels of equal size and with identical teeth, which are evenly distributed on a circular path. having. The intermediate wheels are coupled to a shaft pinion which is arranged on the drive shaft. The rotor of the electric motor is arranged on the inner shaft net, so that it also represents the flywheel.
  • the stator of the electric motor is located next to the disc wheel with internal teeth and carries a multi-phase winding which is connected to the electrical load circuit. Furthermore, the rotor windings are connected to the external control circuit via slip rings. In order to achieve a better use of space, the rotor is designed so that the iron core consists of two overlapping halves that are bent towards each other. The flywheel and rotor windings are located in the space between the two halves.

Abstract

L'appareil de charge comporte un arbre moteur central a pedales (5) entrainant par l'intermediaire d'une roue libre une roue pleine (21) comprenant une denture interieure couplee de maniere appropriee a trois roues d'entrainement. Celles-ci entrainent par leur denture un arbre interieur (10) qui est dispose autour de l'arbre moteur. Sur l'arbre interieur est place le rotor d'un moteur electrique rotatif entoure d'une armature (4) comportant un enroulement polyphase. L'armature (4) est disposee entre une partie interne et une partie externe d'un bati. Les enroulements du rotor recoivent le courant d'excitation par l'intermediaire d'une bague collectrice; les enroulements de l'armature sont attenants a un ensemble de freinage.
