Abstract

A hydromechanical transmission has an operating assembly including an input hydrostatic unit (50) and an output hydrostatic unit (60), each having a rotating cylinder (180, 182) and piston element (210, 212) and a non-rotating yoke element (150, 151). The non-rotating elements are yoke elements (150, 151) linked together to react the separating forces internally, bypassing the housing (120).
