Abstract (en)
[origin: WO0019127A1] A transmission for speed changing and steering of a vehicle includes a first hydrostatic pump (52) and motor (53), a first differential (24') for speed changing, a second hydrostatic pump (71) and motor (72), and a second differential (23') for steering. A prime mover drives the first pump (52), and the second pump (71) is driven by the output from the first motor (53). The second motor (72) drives the second differential (23') for steering the vehicle.
