Abstract:
1. A traction belt and chain drive transmission 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 projecting out of the frame, comprising: gear transmissions with gear wheels, which are embodied as belt and chain drives, located between the input shaft and the output shaft, all of the gear wheels are constantly in rotation during operation, 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, the traction mechanisms are reinforced with aramide, Kevlar, carbon fibers or other fibrous materials, wherein: the traction mechanisms are 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 the at least one component does not touch the traction mechanisms, and the kidney-like shape of the traction mechanisms during no-load rotation is formed by a convex curvature of a driving side and by a concave curvature of a slack side, and the kidney-like shape of the traction mechanisms under load is formed by a straight shape of the driving side and by a concave curvature of the slack side, and the at least one component includes a traction guide with plural pressure bearings which press against the traction mechanism.
