An axle driving apparatus comprising a combination of a speed-change HST for coupling a variable-capacity pump and a motor with a fluid on the one hand and a steering HST for coupling a variable-capacity pump and a motor with a fluid on the other hand, configured in such a manner that the two HSTs are accommodated in a common housing. The motor output of the speed-change HST is transmitted to a differential arrangement for differentially coupling a pair of axles, and the motor output of the steering HST is transmitted to a differential arrangement for di...
[ What is claimed is:] [1.] An axle driving apparatus comprising:a forward/rearward setting operation means;a speed-change operation means;a steering operation means;a pair of axles;a speed-change HST including a fluid pressure pump of variable capacity type and a fluid pressure motor coupled to each other by a fluid;a first differential arrangement power-coupled to the output means of the motor of said speed-change HST for differentially coupling said pair of said axles to each other;a first adjusting means which can change the capacity and rotational d...
