Die Erfindung betrifft ein Belastungsgerät für physiologische Untersuchungen, das eine von der zu untersuchenden Person angetriebene Welle, einen Antrieb mit Freilauf, ein Übersetzungsgetriebe, eine Schwungmasse, die mit der Beschleunigungsseite des Übersetzungsgetriebes gekoppelt ist, einen mitlaufenden Elektromotor im Bremsbetrieb, an den externe elektrische Regel- und Laststromkreise angeschlossen werden. In der ärztlichen Praxis werden immer häufiger Untersuchungsmethoden angewandt, bei denen nicht nur sta tische, sondern auch dynamische Werte unter Belastung ermittelt werden. Die dynamischen Werte spielen in der prophylaktischen, Rehabilitations-, allgemeinen, Sport- und arbeitsmedizinischen Diagnostik eine wichtige Rolle. Die Belastung wird zweckmässigerweise durch Radfahren hergestellt, das alten und jugendlichen bzw. geübten und ungeübten Patienten die gleiche Beanspruchung auferlegt. Das Radfahren wird weiterhin in liegender und stehender Körperposition durchgeführt. Die an die Belastungssysteme gestellten allgemeinen Forderungen sind: variable Belastung, unschädlich, kann beliebig abgebrochen werden, soll physiologisch und reproduzierbar sein. Einen besonderen Vorteil stellt eine Rückkopplung dar, wenn das Belastungssystem durch die funktioneilen Parameter/Atmung, EKG, Blutdruck usw./ gesteuert werden kann Bisherigen Kenntnissen zufolge wurden zur Herstellung von Belastungen folgende technische Lösungen verwendet: WirbelStrombremsung, Elektromotor im Bremsbetrieb, das System Dynamo-Motor-Tachometer, Waagenmotor, mechanische Bremsung usw. Die Nachteile der aufgezählten Varianten sind: der robuste Aufbau, hohe Herstellungskosten, grosse Grundreibung, Zwangssysteme durch die Charakteristiken von Rotationsmaschinen, hohe Stromaufnahme, drehzahlab- hängige Belastung.The invention relates to a loading device for physiological examinations, which is a shaft driven by the person to be examined, a drive with freewheel, a transmission gear, a flywheel, which is coupled to the acceleration side of the transmission gear, a rotating electric motor in braking mode, to the external electrical control - and load circuits are connected. In medical practice, 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. The general demands placed on the stress systems are: 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./ According to previous knowledge, 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.
Von verschiedenen bekannten physiologischen Belastungseinheiten erwähnen wir das von den MEDICOR-Werken vertrie bene Gerät KE 21, das über einen Pedalantrieb mittels Freilauf eine Schwungmasse, bzw. letztlich einen Elektromotor besonderer Bauart im Bremsbetrieb angetrieben wird. Der Elektromotor wird an externe Regel- bzw. Belastungsstromkreise angeschlossen, über die die gewünschte Last eingestellt, bzw. die Kompensation der inneren Reibung, die etwa 40 - 50 W ausmacht, vorgenommen werden kann. Die bisher bekannten Einrichtungen sind - obwohl sie ihrer grundlegenden Aufgabe gerecht werden - aus dem Aspekt unvorteilhaft, dass ein zu grosses Eigengewicht vorhanden ist, wodurch die Handhabung bzw. der Transport erschwert wird, zur Kompensierung der inneren Reibung aufwendige Lösungen notwendig sind, deren Genauigkeit nicht immer ausreichend ist.Of various known physiological load units, we mention 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.

An den Elektromotor sind externe elektrische Regel- und Belastungskreise angeschlossen, des weiteren schliesst sich die erfindungsgemässe Antriebswelle über einen Freilauf an ein Scheibenrad mit Innenverzahnung an, das im Inneren mehrere gleich grosse und mit gleichzahligen Zähnen herausgebildete Zwischenräder, die an einer Kreisbahn gleichmässig verteilt sind, aufweist. Die Zwischenräder sind mit einem Wellenritzel gekoppelt, das an der Antriebswelle angeordnet ist. Der Läufer des Elektromotors ist an der Innenwelle angeord net, so dass dieser Gleichzeitig die Schwungmasse darstellt. Der Stator des Elektromotors befindet sich neben dem Scheibenrad mit Innenverzahnung und trägt eine Mehrphasenwicklung, die an den elektrischen Belastungskreis angeschlossen ist. Des weiteren liegen die Läuferwicklungen über Schleifringe am externen Regelstromkreis an. Um eine bessere Raumnutzung zu erreichen, ist der Läufer so herausgebildet, dass der Eisenkern aus zwei überlappten Hälften besteht, die zueinander gebogen sind. Im Raum zwischen den beiden Hälften befinden sich die Schwungmasse und die Läuferwicklungen.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.

Bei einem vorteilhaften Ausführungsbeispiel der Erfindung besteht der Stator aus einem inneren und einem äusseren Gehäuseteil sowie aus einer Armatur, die zwischen diesen, dμrch Gewindespindeln befestigt, angeordnet ist. Die Wellen der Mitnehmerräder sind im inneren Gehäuseteil befestigt.In an advantageous embodiment of the invention, the stator consists of an inner and an outer housing part as well as a fitting which is arranged between them, by means of threaded spindles. The shafts of the driving wheels are fastened in the inner housing part.
Die Erfindung wird im weiteren anhand eines in der bei- gelegten Zeichnung dargestellten Ausführungsbeispieles näher beschrieben. In der Zeichnung zeigenThe invention is described in more detail below on the basis of an exemplary embodiment shown in the accompanying drawing. Show in the drawing

Fig. 2 einen Schnitt entlang der Linie II-II.Fig. 2 shows a section along the line II-II.
Das in Fig.1 dargestellte physiologische Belastungsgerät besteht aus einem Stator und einem angeschlossenen Läufer. Der Stator besteht aus einem scheibenförmigen, nach innen ausgesparten Aussengehäuse 1 und aus einem Innengehäuse 3, das durch Gewindespindein 2 gehalten wird, zwischen dem Innen- bzw. Aussengehäuse 1,3 ist eine Lamellenarmatur 4 angeordnet. Die Armatur besitzt Polnuten und trägt eine Dreiphasenwicklung.The physiological exercise device shown in Fig.1 consists of a stator and a connected rotor. The stator consists of a disc-shaped, inwardly recessed outer housing 1 and an inner housing 3, which is held by a threaded spindle 2, between the inner and outer housing 1, 3 is a lamellar valve 4 arranged. The valve has pole slots and carries a three-phase winding.
Im Inneren des Stators befindet sich zentrisch eine Antriebswelle 5, die durch die Lager 6,7 gelagert wird. Die Antriebswelle 5 ragt beiderseitig über die Seitenwän de und trägt jeweils ein Pedal 8,9. Die Antriebswelle 5 ist durch eine innere Welle 10 umgeben, die mit der Antriebswelle 5 unmittelbar nicht verkoppelt ist und durch das Lager 11 im äusseren Gehäuse 1 bzw. durch das Lager 12 im inneren Gehäuse 3 gelagert wird.In the interior of the stator there is a drive shaft 5 which is supported by the bearings 6, 7. The drive shaft 5 protrudes on both sides of the side walls and carries a pedal 8.9. The drive shaft 5 is surrounded by an inner shaft 10, which is not directly coupled to the drive shaft 5 and is supported by the bearing 11 in the outer housing 1 or by the bearing 12 in the inner housing 3.
Die innere Welle 10 weist beiderseitig einen Bund auf, der durch Eisenjochs 13, 14 begrenzt ist. Die Eisenjochs 13, 14 sind scheibenförmig und an ihren Enden kammförmig zueinander gebogen, so dass diese Megnetkerne bilden. Im Raum zwischen den Eisenjochs 13, 14 befinden sich die Schwungmasse 15, die umliegende Y/ickelspule 17 und die Läuferwicklungen 17. Die Klemmen der Wicklungen des Läufers 17 sind an Schleifringen 18 angeschlossen, von denen die im äusseren Gehäuse 1 befestigten Kohlebürsten 19 den Strom abgreifen. Der Läufer wird über die Antriebswelle 5 mittels Pedalen 8,9 angetrieben. Die Antriebswelle 5 ist über einen Freilauf 20 mit dem Scheibenrad 21 gekoppelt. Durch den Freilauf 20 wird erreicht, dass das Scheibenrad 21 ein Drehmoment nur aus einer Richtung erfährt, so dass beim Rotieren durch die zeitweilig stehenden Pedalen auf das Scheibenrad keine Bremswirkung ausgeübt wird.The inner shaft 10 has a collar on both sides, which is delimited by iron yokes 13, 14. The iron yokes 13, 14 are disc-shaped and are comb-shaped at their ends so that they form megnet cores. In the space between the iron yokes 13, 14 there are the flywheel 15, the surrounding yoke coil 17 and the rotor windings 17. The terminals of the windings of the rotor 17 are connected to slip rings 18, of which the carbon brushes 19 fastened in the outer housing 1 connect the current tap. The rotor is driven via the drive shaft 5 by means of pedals 8.9. The drive shaft 5 is coupled to the disk wheel 21 via a freewheel 20. It is achieved by the freewheel 20 that the disk wheel 21 experiences a torque only from one direction, so that no braking effect is exerted on the disk wheel during rotation by the temporarily stationary pedals.
Zwischen Scheibenrad 21 und innerer Welle 10 befindet sich die in Fig. 2 im Schnitt dargestellte Beschleunigungsübersetzung. Das Scheibenrad ist am inneren Rand verzahnt. Die Verzahnung stimmt in unserem Falle mit drei Mitnehmerritzeln 22, 23, 24 überein. Die Mitnehmerritzel 22, 23, 24 sind leichte Kunststoffzahnräder, deren Wellen im inneren Gehäuse 3 gelagert sind. In Fig. 1 ist das Mitnehmerritzel 22 und dessen Welle 25 zu sehen. Die Wellen der Mitnehmerritzel 22, 23, 24 sind an den Spitzen eines gleichschenkligen Dreiecks angeordnet, so dass diese im gleichen Abstand zur inneren Welle 10 zu finden sind. Die innere Welle 10 weist im Bereich der Mitnehmerritzel 22, 23, 24 eine Verzahnung auf, um durch das Drehen des Scheibenrades ein beschleunigtes Rotieren der inneren Welle 10 zu erreichen.The acceleration transmission shown in section in FIG. 2 is located between the disk wheel 21 and the inner shaft 10. The disc wheel is on the inner edge interlocked. In our case, the teeth match three driver pinions 22, 23, 24. The driver pinions 22, 23, 24 are light plastic gearwheels, the shafts of which are mounted in the inner housing 3. In Fig. 1 the driver pinion 22 and its shaft 25 can be seen. The shafts of the driver pinions 22, 23, 24 are arranged at the tips of an isosceles triangle, so that they can be found at the same distance from the inner shaft 10. The inner shaft 10 has teeth in the area of the driver pinions 22, 23, 24 in order to achieve an accelerated rotation of the inner shaft 10 by rotating the disk wheel.
Bei obiger Anordnung der Beschleunigungsübersetzung wirkt nur das Drehmoment auf die innere Welle, da sich die radialen Druckkräfte gegenseitig aufheben.With the above arrangement of the acceleration ratio, only the torque acts on the inner shaft, since the radial compressive forces cancel each other out.
Bei der Betätigung des erfindungsgemässen physiologischen Belastungsgerätes setzt die zu Untersuchende Person durch die Pedalen 8,9 den Läufer im Inneren des Gerätes in Drehbewegung. Der Reibungsverlust des ganzen Antriebes beträgt etwa 4 - 5 W, was eine bekannte Konstante ist und somit bei der Ermittlung hinzugerechnet werden kann. Beim Drehen des Läufers wird durch die Wicklung des Läufers 17 durch eine auf der Zeichnung nicht dargestellte Regeleinheit ein Erregerstrom geleitet, wobei durch das entstandene Magnetfeld in den Wicklungen eine Dreiphasen- Spannung induziert wird. Die Armatur wird an eine hier nicht dargestellte Bremseinheit, die im grundegenommen ein verstellbarer Lastwiderstand ist, angeschlossen, so dass der Arzt das Bremsmoment einstellen kann. Bei dem Ausführungsbeispiel kann die Drehzahl im Bereich von 20 - 100 U/min geändert werden, wobei die abgegebene Leistung maximal βOO W betragen kann. Dadurch, dass die Erregung und die Belastung voneinander unabhängig sind, kann die Last drehzahlunabhängig stufenlos geändert werden. Bei dem erfindungsgemässen physiologischen Belastungsgerät ist das kleine Volumen bisher bekannter Einrichtungen ähnlicher Leistung gegenüber charakteristisch. Bei einem Vergleich ist wichtig zu bemerken, dass die erfindungsgemässe Ausführung eine innere Reibung von etwa 4 - 5 W aufweist, die gegenüber dem Reibungsverlust von 40 - 50 W herkömmlicher Vorrichtungen vernachlässigbar und somit eine Kompensation durch eine gesonderte Regelung nicht erforderlich ist. Durch die besondere Ausführung des Übersetzungsgetriebes ist eine geräuscharme, ruhige und gleichmässige Drehbewegung gewährleistet. When the physiological exercise device according to the invention is actuated, the person to be examined sets the runner inside the device by means of the pedals 8, 9 in a rotational movement. The friction loss of the entire drive is about 4 - 5 W, which is a known constant and can therefore be added to the determination. When the rotor rotates, an excitation current is passed through the winding of the rotor 17 through a control unit (not shown in the drawing), a three-phase voltage being induced in the windings by the resulting magnetic field. The valve is connected to a brake unit, not shown here, which is basically an adjustable load resistor, so that the doctor can adjust the braking torque. In the embodiment, the speed can be in the range be changed from 20 - 100 U / min. The fact that the excitation and the load are independent of each other means that the load can be changed continuously regardless of the speed. In the physiological exercise device according to the invention, the small volume of previously known devices of similar performance is characteristic. When making a comparison, it is important to note that the embodiment according to the invention has an internal friction of approximately 4-5 W, which is negligible compared to the loss of friction of 40-50 W of conventional devices, and therefore compensation by a separate regulation is not necessary. The special design of the transmission gear ensures a quiet, smooth and even rotation.
