Abstract
An adjustable drive for auxiliary aggregates of internal combustion engines in which some auxiliary aggregates such as the fan are adapted to be driven from the crankshaft of the internal combustion engine by way of an adjustable V-belt drive automatically regulatable under the influence of the centrifugal force in such a manner that at smaller crankshaft rotational speeds, a transmission with a speed-up results whereas at higher crankshaft rotational speeds a transmission with a speed reduction results; the control range of the V-belt drive is thereby subdivided at least into two partial ranges by a corresponding matching of the lever arms of the flyweights and/or of the spring forces, respectively, of the spring forces themselves, between which lies a range with constant transmission ratio.
