The housing is open Carriers 7, the spout 6 with the gear wheel K) attached. The rotation of the housing 8 causes the wheel 10 to roll on the gear wheel 9, which gives the worm 6 revolutions, which allows the displacement on the periphery of the worm wheel 5 without rotating it set because the Ueberstzung the gear J. 0 in relation to the gear 9 is the gear ratio of the worm 6 to the worm gear 5, which means that the shaft 4 does not rotate, which results in a zero gear ratio - the revolutions. If you want to give this gearbox a gear ratio, for example, set the vehicle in motion , the position of the blocking shift-rotary sleeve JT, which is attached to the sleeve of the gear wheel 9 and on the shaft 4, whereby from the side of the shaft 4 the sleeve has the guide strips 12 and 12, which with the mandrel 14 of the toothed wheel 9 and the mandrel j_5 of the shaft 4 work together when moving the sleeve J. in the direction of the gear 9 and when turning to the left then there is a partial rotation of the wheel against the shaft 4 and
