Abstract
The operational speed of a fluid drive unit in a hydromechanical transmission is limited by means of an overspeed preventing, one-way clutch establishing a positive drive connection between torque transmitting elements of the hydromechanical transmission. Two power paths are established between the planetary gear unit and the input shaft of the transmission to drive an output shaft at a variable drive ratio controlled by a variable displacement type of fluid drive unit. One of the power paths is established through fixed ratio gearing while the other power path is established through the fluid drive units while operating within a speed ratio range limited by the one-way clutch.
