ABSTRACT:
An integrated hydrostatic transmission has a housing comprised of two separable elements detachably joined together along a substantially horizontal parting plane. A hydrostatic transmission including a hydrostatic pump, a hydrostatic motor, and a center section is separately mounted within the housing. The center section comprises a generally L-shaped member having a hydrostatic pump and motor mounting surfaces thereon disposed at right angles to each other. A pair of fluid ports is on each of the mounting surfaces, and internal passageways are in the L-shaped member connecting each of the fluid ports on one of the mounting surfaces with one of said fluid ports being on the other of the mounting surfaces. The L-shaped member comprises first and second legs integrally joined and extending at right angles to each other, with the first leg normally extending in a horizontal direction, and the second leg normally extending in a vertical direction. The first leg has upper and lower surfaces with the pump mounting surface being located on the upper surface. The pump is mounted on the pump mounting surface and has an axis of rotation. The second leg has a first surface extending upwardly from the upper surface of the first leg, and a second surface opposite and parallel to the first surface of the second leg with the motor mounting surface being on the second surface of the second leg. The motor has an axis of rotation perpendicular to the axis of rotation of the pump being mounted on the second surface of the second leg. The pump has an input power shaft extending through the housing.
