Abstract
A crank-CVT transmission which has a freewheel device connected to an output shaft of the transmission. The device selectively enables and blocks a relative rotation between the device and the output shaft. The transmission further has a switching unit adapted to switch the device and an internal shaft, which can be connected to the output shaft and by a connecting element to a differential. The internal shaft can be displaced in the axial direction of the output shaft. The transmission further has an actuator interacting with the switching unit and adapted to initiate the switch of the device. The actuator has a first mechanism adapted to displace the internal shaft in the axial direction, disconnecting the internal shaft from the differential a second mechanism adapted to drive the switching unit. The second mechanism is coupled to the first mechanism and is driven after the first mechanism.
