Description
BESCEiREIBÜNGDESCRIPTION
Bekannt ist, daß Trainingsgeräte für den Fitness- und Leistungssporfbereich mit Gewichten, aerodynamischen
(Windräder) und elektrodynamischen Widerständen (Wirbelstrombremsen) arbeiten, die der Trainierende zu
überwinden hat. Die Regelbarkeit der Gewichte und aerodynamischen Widerstände erfolgt von Hand.
Wirbelstrombremsen bieten die Möglichkeit, die Widerstandskraft über den aufgebrachten Strom zu regeln.
Die Erfassung der vom Sportler erreichten Kraft erfolgt über Kraftmeßdosen, in hydraulischen Systemen über
Druckgeber, bei der Verwendung von Umienkrollen über die Auflagekräfte, bei elektrodynamischen Anwendungen
über die Erfassung des Generatorstromes.
Die Erfassung der zeitabhängigen Größen ermöglicht eine umfassende Auswertung.It is known that training equipment for fitness and competitive sports works with weights, aerodynamic (wind turbines) and electrodynamic resistances (eddy current brakes) that the trainee has to overcome. The weights and aerodynamic resistances can be controlled manually. Eddy current brakes offer the possibility of regulating the resistance force using the current applied. The force achieved by the athlete is recorded using load cells, in hydraulic systems using pressure sensors, when using pulleys using the contact forces, and in electrodynamic applications using the generator current.
The recording of time-dependent variables enables a comprehensive evaluation.
Problemproblem
Der im Anspruch 1 angegebenen Erfindung liegt das Problem zugrunde, ein Trainingsgerät zu entwickeln, das über einen Rechner prozeßgesteuert mit veränderlichen Widerstandskräften arbeiten kann und auch während eines Zyklus veränderliche Werte aufbringen kann.The invention specified in claim 1 is based on the problem of developing a training device that can work with variable resistance forces in a computer-controlled process and can also apply variable values during a cycle.
Die Erfassung der vom Nutzer eingeleiteten Kraft soll so erfolgen, daß alle Komponenten, wie Lagerreibung, Trägheitskäfte, Reibungskräfte in den Laufrollen und Bremskräfte erfaßt werden.The force introduced by the user should be recorded in such a way that all components, such as bearing friction, inertia forces, friction forces in the rollers and braking forces are recorded.
Der Bereich Bremsung und der Bereich Zugkrafterfassung sollten mechanisch getrennt sein, um Beeinflussung der Messung zu vermeiden.The braking area and the traction force measurement area should be mechanically separated to avoid influencing the measurement.
Die Erfindung realisiert die o.g. Probleme mit dem Ziel, eine optimale Bremskraftsteuerung und Zugkrafterfassung zu ermöglichen.The invention solves the above-mentioned problems with the aim of enabling optimal braking force control and traction force detection.
Die eingeleitete Zugkraft bewirkt ein Abrollen des Seiles von der Rolle und leitet ein Drehmoment ein. Die Drehbewegung der Rolle fuhrt zum Aufwickeln eines Gummiseiles, das später das Einholen des Zugseiles beim Zurückführen der Arme gewährleistet. Die Rolle stützt sich auf einer drehbar gelagerten Platte ab, die sich auf der einen Seite auf einen Biegebalken abstützt. Die im Biegebalken auftretende Verformung (resultierend aus der äußeren Zugkraft) wird über Dehnmeßstreifen erfaßtThe introduced tensile force causes the rope to unroll from the roller and introduces a torque. The rotating movement of the roller leads to the winding of a rubber rope, which later ensures that the traction rope is pulled in when the arms are returned. The roller rests on a pivoting plate, which rests on a bending beam on one side. The deformation occurring in the bending beam (resulting from the external tensile force) is recorded using strain gauges
Das Drehmoment der Welle wird über einen Zahnriemen auf eine zweite Welle übertragen, auf der sich die Wirbelstrombremse befindet und die notwendige Bremskraft erzeugt. Die Verwendung von zwei Wellen entkoppelt die Systeme Zugkrafteinleitung und Abbremsung, vermindert somit die Beeinflussung der Zugkrafterfassung durch die Wirbelstrombremse. Das Übersetzungsverhältnis zwischen den Wellen kann verändert werden.The torque of the shaft is transmitted via a toothed belt to a second shaft on which the eddy current brake is located and generates the necessary braking force. The use of two shafts decouples the traction force introduction and braking systems, thus reducing the influence of the eddy current brake on the traction force detection. The transmission ratio between the shafts can be changed.
