ABSTRACT:
A transaxle housing is provided for a small-sized vehicle such as a grass-mowing lawn tractor and encloses an internally located hydrostatic transmission in association with speed reducing gearing and mechanical differential for reasons of compactness and simplicity of manufacture. The axle housing comprises two members connected together alone a parting plane to define a number of internal chambers, at least one chamber used to enclose the hydrostatic transmission and remaining chambers enclosing speed reducing gearing and differential. One housing element is provided with a vertical input shaft which is operatively connected through bevel gearing to a hydraulic pump, the pump mounted perpendicular and fluidly coupled to a hydraulic motor, the rotary axis of the hydraulic motor being coincident with the parting plane of the housing and parallel to the rotating axes of the half shafts of the transaxle. The bevel gearing being located within either the chamber enclosing the hydrostatic transmission or within one of the remaining chambers enclosing the reduction gearing and differential.
