Abstract:
1. A hydrostatic transmission assembly comprising: a first gerotor motor including a first output shaft aligned along a first axis; a pump housing connected to the first gerotor motor; a first variable displacement pump including a first driven shaft mounted to the pump housing and aligned along a second axis, the second axis being generally perpendicular to the first axis, the first variable displacement pump being in fluid communication with the first gerotor motor via passages in the pump housing; a second gerotor motor including a second output shaft generally aligned along or generally parallel to the first axis, the second gerotor motor being connected to the pump housing on an opposite side of the pump housing as the first gerotor motor; a second variable displacement pump including a second driven shaft mounted to the pump housing and aligned generally parallel to the second axis, the second variable displacement pump being in fluid communication with the second gerotor motor via passages in the pump housing; and a radiator disposed between the pump housing and at least one of the gerotor motors.
