Abstract
A multi-range synchronous shifting concentric gear train package having two inputs and a single output which when connected to a mechanical input and to the output of an infinitely variable drive device (shown as a hydrostatic component) powered by the same mechanical input with the input axes aligned with the center of rotation of the components of the gear package forms an all concentric multi-range synchronous shifting hydro-mechanical transmission. The combination of the same gear train package with mechanical and hydrostatic inputs in combination with right and left output planetary gear sets and a hydrostatic steer arrangement powered by the same mechanical input forms a hydromechanical steering transmission having a concentric gear train package. Gear train elements for exchanging the rotational movement of inner and outer shafts of a set of concentric shafts to permit implementation of the concentric gear train package are also disclosed in detail.
