The gearing consists of a four-shaft toothed-gear planetary (epicyclic) transmission and a parallel, infinitely variable hydrostatic transmission, as well as additional gear wheels; toothed clutches achieve the various gears (speeds), whereas the hydrostatic transmission effectuates the infinitely variable adjustment of the infinitely variable transmission of the entire gearing; the gear shifting takes place at a synchronous speed of rotation, load-free, and without interrupting the tractive force. The special characteristic consists in the design of the toothed clutches and the control that has been provided for the shifting action, the effect being that the shifting into a new gear and out of the previous one is completely smooth and free of jolts. Apart from provding this comfortable and easy shifting action, the gearing also possesses an extensive range, overall, of transmission adjustment capability, as well as a good efficiency factor. Thus, it is very suitable for application in motor vehicles.
