<p>A gearbox comprising a combination of a planet gear having an outer ring (17), planet wheels (19) and a sunwheel (5) and a linear gear (1A, 1B; 2; 21; 22; 3; 13) with a drive shaft (4) mounted coaxially therein. A rotatable toothed sleeve (3) having inner teeth and outer teeth is mounted in a housing (24) in the linear gear for displacement in the axial direction of the linear gear and the drive shaft (4) with the aid of a gear shift (6). The gear shift (6) is journalled on a guide (8) and can be displaced by means of a gear shift displacing device (10) to different positions of engagement with teeth on the sunwheel (5) and with two toothed rings (21, 22) in the linear gear.</p> |
