<p>A hydromechanical transmission that can be used as a simple and efficient continuously variable transmission comprising a differential mechanism (4) for forming either a first high-speed mechanical transmission line (a) or a second low-speed mechanical transmission line (b), a hydraulic power transmission mechanism (8) comprising two hydraulic pump/motors (5, 7), one of said hydraulic pump/motors being of the fixed displacement type, and the other is of the variable displacement type, and a mode selection mechanism for selecting either a low-speed mode or a high-speed mode in function of that mechanical transmission line (a, b) connecting the output shaft (19) to the input shaft (13). </p> |
