Abstract
A gear change device for including a first and a second primary shaft, selectively connectable to a driving shaft of a motor vehicle by a double clutch engagement device, and a first and a second secondary shaft. A plurality of gear selector devices rotatably couples each of the freely rotatable gear wheels with the shaft on which it is mounted, and, at least one rotatable actuator drum, for controlling the selector devices, having a plurality of cam tracks. The selector devices include respective fork-like actuator members and each has a cam follower element engaged in a respective cam track of the respective actuator drum. Each pair of cam tracks adjacent to each other provided on an actuator drum controls fork-like actuator members which are associated to different secondary shafts and which have the can follower elements thereof engaged on the drum in positions angularly spaced with respect to each other.
