Anwendungsgebiet der ErfindungField of application of the invention
Die Erfindung betrifft ein Pedal zur meßtechnischen Erfassung der Tretkraft-Verläufe während der zyklischen Tretbewegung im Radsport.The invention relates to a pedal for metrological detection of treadmill gradients during cyclic pedaling in cycling.
Charakteristik des bekannten Standes der TechnikCharacteristic of the known state of the art
Die zielgerichtete Beeinflussung der Trettechnik stellt in den Radsportdisziplinen e!ne wichtige Leisturgsreserve dar, um das im Training physisch erworbene Kraftpotential effektiv in vortriebswirksame Leistung umzusetzen.The goal-oriented influence of the technology of traction in the cycling disciplines e ! ne important Leisturgsreserve to implement the physically acquired in training power potential effectively in propulsive power.
Dazu ist das Erfassen der Tretkraft, differenziert in die auf das Pedal in vertikaler und horizontaler Richtung aufgebrachten Kraftkomponenten, sowie deren zyklische Zuordnung zur jeweiligen Kurbelstellung erforderlich. Bekannt sind bisher Kraftmomentmessungen an der Tretkurbel zur Ermittlung eier Antriebsleistung. Bekannt ist auch eine Einkomponenten-Kraftmeßeinrichtung für das Fahrradpedal zur Ermittlung von Maximalkraftwerten für Dimensionierungsaufgaben (Forschungsergebnis TU Dresden).For this purpose, the detection of the treading force, differentiated in the applied to the pedal in the vertical and horizontal direction force components, and their cyclical assignment to the respective crank position is required. So far, momentum measurements on the pedal crank are known to determine the drive power. Also known is a one-component force measuring device for the bicycle pedal for determining maximum force values for dimensioning tasks (research result TU Dresden).
Mit diesen Meßeinrichtungen ist es nicht möglich, die zur Ermittlung des Tretkraftvektors (Größe und Lage) erforderlichen Meßdaten zu liefern, damit ist es auch nicht möglich, die vortriebwirksamen und Verlustanteile der eingesetzten Tretkraft nachzuweisen.With these measuring devices, it is not possible to provide the measurement data required for determining the pedaling force vector (size and position), so that it is also not possible to prove the propulsion-effective and loss components of the pedaling force used.
Ziel der ErfindungObject of the invention
Ziel der Erfindung ist es(eine Meßeinrichtung zu schaffen, mit welcher die Tretkraft des Sportlers hinsichtlich der Effektivität des Krafteinsatzes meßtechnisch analysiert werden kann, um ihm zielgerichtet eine effektive Trettechnik anzutrainieren.The aim of the invention is ( to provide a measuring device with which the treadle force of the athlete can be analyzed by measurement with respect to the effectiveness of the use of force in order to train him effectively an effective technique.
Daiiogung des Wesens der ErfindungAccuracy of the essence of the invention
Der Erfindung liegt die Aufgabe zugrunde, die Tretkraft auf das Pedal getrennt in die vertikale und horizontale Komponente und die Winkelstellung des Pedals im Tretzyklus als Impulsfolge jedem Einzelzyklus genau zuordenbar zu messen. Dias wird erfindungsgemäß dadurch erreicht, daß zwischen Pedaltrittplatte und Pedalachse ein oder mehrere Kraftsensoren, ein· inkrementaler Drehwinkelgeber sowie ein optoelektronischer Signalgeber, bestehend aus dem mit der Trittplatte verbundenen Lichtdiodenträger und mit der Pedalachse verbundener dcniinscheibe, angeordnet sind. Bei Einsatz eines Zweikomponenten-Kr1. sensors stützt sich dieser über die Pedallager auf der Pedalachse ab und nimmt die Pedaltrittplatte auf.The invention has for its object to measure the pedaling force on the pedal separately in the vertical and horizontal component and the angular position of the pedal in the cycle cycle as a pulse train each individual cycle accurately assigned. According to the invention, slides are achieved by arranging one or more force sensors, an incremental rotation angle sensor and an optoelectronic signal generator, consisting of the light diode carrier connected to the tread plate and disc plate connected to the pedal axle, between pedal tread plate and pedal axle. When using a two-component Kr 1 . The sensor is supported by the pedal bearings on the pedal axle and receives the pedal plate.
Ee ist möglich eine Kombination aus mehreren Einzelsensoren einzusetzen, wobei den beiden Kraftkomponenten zugeordnete Kraftaufnehmerzu einem System gekoppelt sind und sich so ebenfalls einerseits auf die Pedalachse abstützen und andererseits die Pedaltrittplatte aufnehmen.Ee is possible to use a combination of several individual sensors, wherein the two force components associated force sensors are coupled to a system and so also supported on the one hand on the pedal axle and on the other hand record the pedal kick plate.
Der inkrementale Geber dient zur Messung der Drehbewegung zwischen Pedaltrittplatte und Pedalachse. Zur Erfassung der Nullstellung für jeden Drehzyklus ist der optoelektronische Signalgeber angeordnet. Damit ist es möglich, jedem Winkelimpuls die entsprechenden Kraftwerte eindeutig zuzuordnen. Die Winkelmeßeinrichtung wird noch durch eine in das Pedal eingebaute Leiterplatte komplettiert, die der Erfassung und Formung der Wegsignale dient.The incremental encoder is used to measure the rotational movement between pedal plate and pedal axle. For detecting the zero position for each rotation cycle of the optoelectronic signal generator is arranged. This makes it possible to unambiguously assign the corresponding force values to each angular momentum. The angle measuring device is completed by a built-in pedal circuit board, which serves to capture and shaping the path signals.
