Abstract

A transaxle with a hydrostatic transmission which is compact, reliable and economical to manufacture, including a novel means for hydraulically reducing the speed of the input to the transaxle; an improved differential which is stronger and less complicated than prior art designs; a longer lasting, more effective means of preventing oil leakage from the axle shafts in the transaxle housing; a center section for the hydrostatic transmission supporting the output drive shaft, eliminating the need for additional bearing support; an improved means for hydraulically bypassing the hydrostatic transmission and a unique check valve arrangement for maintaining oil pressure within the hydrostatic transmission. The hydrostatic transmission also includes a pump and a motor whose orientation to one another may be varied according to the space requirements dictated by the size and configuration of the vehicle through the use of a helical gear.
