Actuating arrangement for a gearbox and method of operating the same

Abstract

An aim of the invention is to provide a double clutch transmission enabling shift actuation in multiple gear trains with a single actuator device. The time required for a gear ratio change should also be reduced, hereby improving comfort and operability. To this end, the invention provides that a gear ratio can be shifted with an actuating element through a shifting element and that in the shifted state of this gear ratio, the same actuating element can actuate at least one other shifting element in order to select other gear ratios. A neutral channel wide enough to allow the selection movement of an actuation element is advantageously retained in the shifted state of one or more gear ratios. A shifting element may follow an actuating element with a path hysteresis that is identical to or greater than the path of the shifting element between the neutral position and a final gear position. This can be achieved by making the width of the shifting opening equal to or greater than the sum of the selector finger width and the distance between the neutral position and the final gear positions of the shift fork or by providing play equal to or greater than the path of the shifting element between the neutral position and the final gear position, between the shifting element and the actuating element.
