Abstract: A hydrodynamic-mechanical vehicle drive wherein an engine drives the primary portion of an input clutch whose secondary portion can receive torque with varying degrees of slip and rotates the pump of a counter-rotating hydrodynamic torque converter, either directly or through the medium of a differential. The turbine of the converter is adjacent to the inlet side of the pump and drives the input shaft of a reversing gearing which utilizes a friction clutch to drive the take-off shaft forwardly and a friction brake to drive the take-off shaft in reverse. The turbine and the pump rotate in the same direction during hydrodynamic braking and the pump is then rotated at a speed which depends on the degree of slip of primary portion of the input clutch relative to the secondary portion.
