Abstract:
An integral transaxle apparatus for driving and steering a vehicle, comprising:a housing forming a fluid sump therein;a pair of final output means disposed in said housing;a differential unit disposed in said housing for differentially connecting said final output means with each other;a first transmission system disposed in said housing for steplessly driving said pair of final output means, including a first hydrostatic transmission and a first mechanical transmission, wherein power of a prime mover is transmitted into said differential unit through said first hydrostatic transmission and then said mechanical transmission, anda second transmission system disposed in said housing for accelerating one of said pair of final output means and decelerating the other of said pair of final output means, including a second hydrostatic transmission and a second mechanical transmission, wherein said second mechanical transmission driven by said second hydrostatic transmission branches into two parallel drive trains drivingly connected to said pair of final output means, respectively, so that two oppositely directed equal rotational forces are applied onto said pair of final output means by said two drive trains.
