Abstract
A transmission shift system comprising a synchronizing device for idler wheels, which can be actuated hydraulically and comprises at least one piston that can mesh with a selected idler wheel as the sliding sleeve. The piston can be displaced axially on a shaft via a hydraulic actuation and is non-rotatably connected with it, thus self-locking synchronization is provided.
