1. A rotating hydrostatic transmission comprises a hydrostatic transmission in shaft/rotor (4) an outside the shaft/rotor situated master controller/processor to control and regulate from the outside incoming adjustable power or from the shaft/rotor delivered, wherein the master controller/processor even controls/regulates the split of the power to the two ends (2, 6) of the shaft/rotor or when the power comes in control and take care of the not adjusted power in at the two end ends of the shaft/rotor by controlling/regulating the split of velocity speed and torque ratio, the split is regulated by the angel of the swash plates (7, 8) which adjust the variable displacement in the axial piston pumps/motors (3, 5) with adjustable displacement, the control and regulation is done by transferring a signal of desired/wished position/angel of the swash plate into the shaft/rotor, the transfer is done by two separate pulse width modulated DC fed pulse trains, a different width of the of the pulse is utilized as different signals of the value of the angle, the value of the signal is compared in some slave controller/CMOS logics with an actual position/angel of the swash plate, when there is a difference, the difference is adjusted by a servo which gets its command from the slave controller, the master controller/processor can also switch on and off auxiliary equipment in the shaft/rotor like valves and charge pumps, the controlling/regulating is done inside shaft/rotor by two slave controllers and servo functions, the transfer of power and the on and off function is also done by the two separated DC energized pulse trains which also are voltage regulated, the energized pulse trains are coming in one from each end of the shaft/rotor mechanically via a commutator or contactless by induction from a fixed attached coil (24) over to coil (25) at the end of the shaft/rotor, and wherein one or more tanks/accumulators (1) take care of leakage oil from the case drain of the pumps/motors and also replenish the closed system with oil , the replenishment oil from the tanks/accumulator go by check valves (19, 20) to the inlet and outlet of the pumps/motors, in each inlet and outlet there is a relief valve (17, 18), and the pressure needed to load the tank and to allow charge oil to enter the closed circuit comes from the chase drain. |
