HYDROMECHANICAL AUTOMATIC MULTISTAGE GEARBOX GEAR SHIFTING FOR VEHICLE AND VEHICLE Russian patent published in 2016 - IPC F16H47/06 B60K17/10 

FIELD: machine building.

SUBSTANCE: invention relates to hydromechanical automatic gear shifting boxes speed (AKPP), as well as to move on ground and on water using hydromechanical gearbox. In automatic transmission pinion gears are made as arranged on central gear input shaft and installed with gearing with gear, having various diameters. Each gear is installed on input shaft of one of hydraulic transformer with centrifugal pump and turbine wheels arranged on its input and output shafts and forming wheel working fluid circulation. In circulation congestions accommodates rotary blades of reactor. There are disclosed features of geometrical parameters and forms of profiling of blades of centrifugal wheels pumps and turbines torque converters, as well as their design with vaneless slot diffuser at inlet of turbine wheel.

EFFECT: high efficiency, small dimensions.
