Abstract

The process consists of circular bearer components mounted concentrically on each pedal axle and turning with the axle. Each of these bearers has a stripe-code, as, for example, the ABS system. Two optoelectronic sensors are also placed in each pedal area so as to read these codes. The sensors read both codes simultaneously and are linked to a microprocessor which calculates the turn count in relation to pressure applied. The process is accurate and can be used with any mechanical spring system between pedal and chain. The signal from the processor can be used to inform the cyclist direct or to control an electric servo-drive.

Description

Vorteileadvantages

Das Verfahren ist sehr genau und läßt sich mit verschiedenen mechanischen Federsystemen kombinieren. So sind zwischen Kettenblatt und Tretlager Druck-, Zug- oder Blattfedern oder auch Elastomere denkbar.The process is very precise and can be done with various mechanical spring systems combine. So there are compression, tension or leaf springs or between chainring and bottom bracket elastomers are also conceivable.

Auch kann die Feder im Tretlagergehäuse liegen und als hohler Torsionskörper um die Tretlagerachse liegen oder aus mehreren ringförmig um die Tretlagerachse angeordneten Torsionsstäben bestehen.The spring can also lie in the bottom bracket shell and as a hollow torsion body around the Bottom bracket axis or from several arranged around the bottom bracket axis Torsion bars exist.

Bei einer Federanordnung im Tretlagergehäuse können die beiden ringförmigen Träger des Strichcodes auch in diesem Gehäuse geschützt untergebracht werden.With a spring arrangement in the bottom bracket shell, the two ring-shaped carriers of the Barcodes can also be protected in this housing.

Die Abbildung zeigt beispielhaft den Aufbau einer Meßeinrichtung am Fahrrad. Bei diesem sind beide Sensoren in einem Gehäuse zusammengefaßt das auf das Tretlager aufgeschraubt werden kann. Dadurch ist es einfach auch nachträglich zu montieren.The figure shows an example of the structure of a measuring device on a bicycle. In this case, both sensors are combined in one housing on the bottom bracket can be screwed on. This makes it easy to install later.

Device for optoelectronic power measurement on muscle vehicles, consisting of
  • 1. A split pedal crank drive whose chainring can rotate on the bottom bracket shaft and is supported against it via an elastically deformable element.
  • 2. Two ring-shaped carriers arranged on each of these two parts and rotating concentrically to the bottom bracket axis, on each of which a ring-shaped bar code (such as in ABS systems) is applied.
  • 3. Two optoelectronic sensors arranged on the frame side near the bottom bracket or in the bottom bracket shell.
Kennzeichen
Beide Sensoren lesen je einen Code simultan ab und ein Mikroprozessor errechnet daraus die U/min und aus der Drehzahldifferenz der beiden sich unter Last gegeneinander verdrehenden Codes das Drehmoment.
Auf diese Weise kann in einem Vorgang die Leistung direkt ermittelt werden. Das gewonnene Signal kann entweder zur direkten Leistungsinformation des Fahrers benutzt werden oder zur Steuerung eines elektrischen Servoantriebes.Mark
Both sensors read a code simultaneously and a microprocessor uses this to calculate the rpm and the torque from the speed difference between the two codes rotating under load.
In this way, the performance can be determined directly in one operation. The signal obtained can either be used to provide the driver with direct performance information or to control an electric servo drive.
