A gear device for steplessly variable transmission, comprising an epicyclic gear (10) having a central sun wheel (12), planetary wheels (13), an outer annulus (14) and a planetary wheel carrier (11) for mounting of the planetary wheels, coupled to an output shaft (16). A differential (3) is intercoupled between an input shaft (1) and the sun wheel (12), whereby a drive gear (2) on the shaft is in drive connection with a differential housing (4), while a drive wheel (6) in the differential is in drive connection with the sun wheel (12), and a second drive wheel (7) in the differential is in drive connection with an adjustment wheel (17) which is coupled to the annulus (14). An adjustment appliance (21, 22, 23, 24) is provided for controlling the rotation of the annulus. |
