ABSTRACT:
The hydromechanical transmission is all in all designed as a power splitting transmission having at least two hydraulic machines adapted to selectively act as pumps and motors, a control or connecting block, epicyclic gearing and various clutches, the hydraulic machines adapted to selectively act as pumps and motors forming a preassembled unit or subassembly with the control or connecting block. The subassembly, the epicyclic gearing, the clutches and any intermediate shaft required are arranged in a unitary manner in a common housing, in which the various elements are surrounded with a small clearance. the hydraulic machines adapted to selectively act as pumps and motors are arranged within the overall length of the epicyclic gearing and are axially parallel thereto.
