  • Patent number: 5584772
    Abstract: An infinitely variable hydrostatic torque-routing transmission with at least two operating ranges shiftable via switching elements includes a first, mechanical part, including a planetary differential gear, and a second, hydrostatic part, including two adjustable hydrounits. The hydrounits are coupled to each other energetically, are operable in both directions as pump or motor, and are coupled to the mechanical part. The ring gear is coupled, in the various operating ranges, for control of the direction of rotation and speed of rotation of the transmission output shaft, to a first hydrounit, and with the second hydrounit being in the first operating range in drive connection with the transmission output shaft via an alternating switching element, while the first hydrounit, connected to the ring gear, operates as a pump and the second hydrounit as a motor.
