Transmission system and method for performing a gearshift

摘要

A transmission system and method for operating the transmission system, where the transmission system includes a selector assembly arranged to select between gear ratios instantaneously without substantial power interruption. The selector assembly includes first and second sets of engagement members and an actuator system. The actuator system may have a first actuator member for moving the first set of engagement members, a second actuator member for moving the second set of engagement members, a first actuator device for actuating the first actuator member and a second actuator device for actuating the second actuator member independently of the first actuator device.
