<p>The invention relates to a hydro-mechanical gearbox (3) with a hydraulic pump (10), a hydraulic motor (17) and a set of planetary gears (6). The hydraulic pump (10) is connected to the hydraulic motor by lines (15,16), thereby forming a closed circuit. Either the sun wheel (5) or the planet-carrier (9) of the set of planetary gears (6) is coupled in a rotationally fixed manner to the input shaft (2) of the gearbox (3), and the other one of these two elements (5,9) of the planetary gear (6) is coupled in the same manner to the output shaft (4) of the gearbox (6), and the hollow wheel (8) is coupled to a rotational unit of the hydraulic pump (10), preferably to its casing, while the other rotational unit of the hydraulic pump (10) is coupled to the frame or to the output shaft (4) of the gearbox (6). According to the invention one rotational unit of the hydraulic motor (17), preferably its rotor, is coupled in a rotationally fixed manner to the input shaft of the gearbox (2), and the other unit of the hydraulic motor (17), preferably its stator, is coupled either to the housing of the gearbox (6) or to its output shaft (4).</p> |
