ABSTRACT:
To prevent engine speed from increasing during low-speed operation, a transmission includes a change-gear mechanism, a centrifugal clutch, a control unit and a secondary sheave rotation sensor. The change-gear mechanism has an input shaft, an output shaft and an actuator for changing a change-gear ratio between the input and output shafts. The centrifugal clutch is connected to the output shaft. The control unit controls the actuator. The secondary sheave rotation sensor detects and outputs a rotational speed of the output shaft to the control unit. The control unit controls the actuator based on a target change-gear ratio obtained by dividing a target rotational speed of the input shaft by the rotational speed of the output shaft.
