Gear box switching device mounted in motor vehicle e.g. car, has actuator device that operates frictional elements and closure elements in independent manner

摘要

The device has closure elements (14a) that are connected in series with the frictional elements (13a) of multi-stage coupling units (10a). An actuator device (16a) is arranged within the closure elements. The frictional elements and the closure elements are operated independently by another actuator device (17a). An independent claim is included for method for controlling gear box switching device.
