A differential tooth gear with appliance for control of speed variation has body in which the small and the large central gear wheels are placed, satellites and carrier and appliance for control of speed variation as closed hydro-system, this interacts with the large central gear wheel or pole through pinion hydro-pump and toothed gearing. The differential tooth gear is made of two or more stages connected to each other in such way that the carrier of the first stage is connected to the small central wheel of the second stage, the carrier of the second stage is connected to the small central wheel of the third stage, à the carrier of the n-th stage is connected to the small central wheel of the n+1 stage. Control of speed is performed through large central gear wheels of the first, second, n+1 stage by means of closed loop hydraulic systems installed on those or connected to each other in such a way that the large central gear wheel of the first stage is connected to the small central wheel of the second stage, the large central gear wheel of the second stage is connected to the small central wheel of the third stage, à the large central gear wheel of the n-th stage is connected tothe small central wheel of the n+1 stage, and control of speed is performed through the carriers of the first, second, n+1 stages by means of closed loop hydraulic systems installed on those. |
