Abstract
The invention relates to a device for synchronising a gearbox shaft and two idler gears (75, 76) rotatably mounted on the gearbox shaft, the device having an actuation system (85). The invention is characterised in that the actuation system (85) comprises two actuation elements (95) that are rotatable relative to each other and the idler gears (75, 76), and have a locking mechanism (207) that prevents two speeds from being engaged at the same time.
