Abstract:
This stepless transmission (1) has a transmission motor (7), a clamping motor (8), a control device (9), and a variator (2). The variator (2) has a primary pulley (3), a secondary pulley (4), and a belt (5). The stepless transmission (1) also has a planetary gear mechanism (6) and screw-feeding mechanisms (35, 45) so that the speed of the variator (2) is changed on the basis of the output torque of the transmission motor (7) and the transmission ratio of the variator (2) is fixed on the basis of the output torque of the clamping motor (8).
