Abstract:
The present disclosure relates to a hydro-mechanical transmission having two rotating groups that mount on a common shaft. At least one of the rotating groups operates as a variable displacement pump or motor. At least one of the rotating groups interacts with a torque transfer unit rotatable about the shaft axis relative to both the shaft and the rotating group. The torque transfer unit includes a valve plate, a swash plate and a torque output section that all rotate in unison with one another about the shaft axis relative to the shaft and the rotating group. The valve plate includes an inlet passage for inletting hydraulic fluid to the rotating group and an outlet passage for outletting hydraulic fluid from the rotating group.

Claim (Index 1):
A hydro-mechanical transmission comprising:\n a shaft rotatable about a shaft axis, the shaft having an input end; a pump rotating group including a pump cylinder barrel that rotates in unison with the shaft about the shaft axis, the pump rotating group also including a plurality of pump pistons that axially reciprocate within pump cylinders defined by the pump cylinder barrel, the pump pistons including pump piston shoes; a pump swash plate that does not rotate with the shaft about the shaft axis, the pump swash plate being angularly adjustable relative to the shaft axis to adjust a displacement of the pump rotating group, the pump piston shoes riding on the pump swash plate, a pump valve plate that does not rotate with the shaft about the shaft axis, the valve plate including a pump output passage for outputting hydraulic fluid pumped from the pump rotating group and a pump inlet passage for returning hydraulic fluid to the pump rotating group; a motor rotating group including a motor cylinder barrel that rotates in unison with the shaft about the shaft axis, the motor rotating group also including a plurality of motor pistons that axially reciprocate within motor cylinders defined by the motor cylinder barrel, the motor pistons including motor piston shoes; and a torque output unit rotatable about the shaft axis relative to both the shaft and the motor rotating group, the torque output unit including a motor valve plate, a motor swash plate and a motor torque output section that all rotate in unison with one another about the shaft axis relative to the shaft and the motor rotating group, the motor valve plate including a motor inlet passage that provides fluid communication between the pump outlet passage and the motor rotating group and a motor outlet passage that provides fluid communication between the motor rotating group and the pump inlet passage, the motor piston shoes riding on the motor swash plate.
