Abstract
A hydro-mechanical transmission 10 having fluid motor 48 that is entirely rotatable to eliminate the need for separate gearing is disclosed. The gearless hydro-mechanical transmission 10 provides a variable speed and torque output from an external mechanical power source 14 and an external hydraulic power source 20. The hydro-mechanical transmission 10 comprises a stationary case 42, an output shaft 44 mounted within the case for rotation about a central axis 52, a mechanical input 46 mounted in coaxial alignment with the output shaft 44 for rotation about the central axis 52 with the input 46 being connected to and rotatable driven by the mechanical power source 14, a rotatable hydraulic motor 48 having a drive unit 60 for rotatably driving a driven unit 62 with the driven unit 62 being coupled to drive the output shaft 44, and means 100 for conducting pressurized hydraulic fluid from the hydraulic power source 20 to the hydraulic motor 48 for driving the driven unit 62 of the hydraulic motor 48 by the drive unit 60.
