Abstract:
1. A hydraulic transmission assembly for an associated ground vehicle comprising: a pump unit configured to operably connect to an associated motor of the associated ground vehicle; a manifold fluidly connected to said pump unit, the manifold including means for mounting to the associated ground vehicle; and a hydraulic motor assembly connected to said manifold, said motor assembly including: wherein pressurization of said hydraulic motor assembly via said pump unit rotates said motor housing relative to said stationary output shaft which, in turn, rotates the associated wheel assembly in one of a first direction and second direction, wherein said manifold is fluidly connected to said at least one passage of said pump unit and said at least one passage of said output shaft via at least one internal passage, wherein said manifold fluidly connects said pump unit and said hydraulic motor assembly with no intervening external fluid lines.
