Abstract
A belt and chain drive for vehicles or for use in drive technology with an input shaft and an output shaft supported on a frame, the input shaft and the output shaft project out of the frame, with the following features: a) gear transmissions with gear wheels, which are embodied as belt and chain drives, are located between the input shaft and the output shaft, b) all of the gear wheels are constantly in rotation during operation, c) the gear transmissions located between the input shaft and the output shaft are embodied as belt and chain drives with toothed belts as traction mechanisms and with pulleys as gear wheels, d) the traction mechanism are reinforced with aramide, Kevlar, carbon fibers or other fibrous materials, is characterized in that e) the traction mechanism is pressed into a kidney-like shape onto the pulleys by at least one component during no-load rotation, and that under the effect of load this component does not touch the traction mechanism, and f) the kidney-like shape of the traction mechanism during no-load rotation is formed by a convex curvature of the driving side and by a concave curvature of the slack side, and g) the kidney-like shape of the traction mec…
