The Application of Mobile Hydrostatic Transmissions

New concepts and evolutions of existing concepts are occurring at an increasing rate in the field of fluid power transmission. This paper discusses the following specific areas relating to open loop, piston type hydrostatic transmissions: the hydrostatic assist drive, the powered wheel, higher horsepower hydrostatic drives, a new concept in variable pumps, variable displacement motor.

With proper application, these developments mean hydrostatic transmissions which are more compact, are easier to apply, are functionally superior, and utilize engine horsepower over a broader vehicle speed range.
