Method and device for measuring force, torque and output on an ergometer or bicycle
TLDR
In this article, the authors proposed a method and a device for measuring force, torque and output on an ergometer or bicycle, where, when the bicycle is used as intended, a torque is transmitted via a shaft (1) onto a flexible drive and further onto the flywheel of the bicycle by two pedal cranks having pedals.Abstract:
The invention relates to a method and a device for measuring force, torque and output on an ergometer or bicycle, wherein, when the ergometer or bicycle is used as intended, a torque is transmitted via a shaft (1) onto a flexible drive and further onto the flywheel of an ergometer or the rear wheel of the bicycle by two pedal cranks having pedals, the flexible drive having a pulley (4) or a sprocket wheel which is non-rotatably connected to the shaft (1) in at least one direction of rotation. According to the invention, elastic torsions of the shaft (1) that result independently from the torque transmission are detected at both sides of the pulley (4) or of the sprocket wheel as a measure of the forces applied to the shaft (1) to determine the torque and the output both of the left and the right leg of the user of the ergometer or the bicycle. Corresponding electrical sensor signals (8, 9) are generated and are supplied to a memory and/or evaluation unit (7) for further processing.read more
