  • Rotating hydrostatic transmision
    Patent number: 9157527
    Abstract: A hydrostatic transmission in the shape of a shaft/rotor comprising two hydraulic pumps/motors with adjustable displacement connected in a closed hydraulic system. The displacement of the pumps/motors is adjusted by adjusting the angle of swash plates of the pumps/motors. The control and regulation of the angle of the swash plates is done by transferring a signal by two separate pulse width modulated DC fed pulse trains. The hydrostatic transmission includes oil accumulators connected to the hydraulic pumps/motors.
