ABSTRACT:
This invention describes an integrated hydro-mechanical transmission having continuous, through zero, variability from maximum forward to maximum reverse and is intended for use in passenger cars and lighter-duty trucks. The integrated hydro-mechanical transmission is capable of achieving high levels of efficiency and lower product cost. The unit is hydrostatically based and is automatically responsive to ratio upshifting as engine speed increases and to downshifting in response to applied load. In addition, the unit is responsive to operator selected inputs for ratio change to accommodate either temporary or extended heavy-load situations.
