ABSTRACT:
A hydromechanical drive assembly having a hydrostatic axial piston motor with a housing and a swash plate and a cylindrical drum located in the housing. A transmission having a housing is located downstream of and coaxial with the axial piston motor and a planetary gear is located in the transmission. A transmission-side driven shaft extends out of each end of the drive assembly. The cylindrical drum and the driven shaft have the same axis of rotation. Spring-actuated hydraulically releasable devices are located in the housing to non-rotatably connect the cylindrical drum of the axial piston motor directly to a ring gear which is non-rotatably connected to the driven shaft.
