ABSTRACT:
A continuously shifting-type steering system includes a pair of left and right hydrostatic continuously variable transmissions each of which is comprised of a hydraulic pump and a hydraulic motor, and a pair of left and right planetary gear mechanisms each having a first sun gear, a second sun gear, a two-step planetary gear and a carrier. A first driving gear connected to an engine, is operably connected commonly to the left and right first sun gears. Left and right second driving gears secured to motor shafts of the left and right hydraulic motors, are operably connected to the left and right carriers, respectively. Left and right output shafts are operably connected to the left and right second sun gears, respectively. Thus, it is possible to provide an increase in the shifting range of the continuously shifting-type steering system, and an enhancement in low-output performance.
